They are designed for large-capacity runs over long hours and require constant feeding from trucks hauling in materials. Equipped with vast conveyor systems, crushers, screeners, sorters, scrapers and grinders, these quarries push the limits of aggregate production and can crush from anywhere between 200 mm to 12 mm or less.

Mobile crushers operate within a smaller footprint but still push the envelope of production. These plants are required to perform similar duties as a stationary site, but in smaller volumes with the added luxury of mobility. The mobility allows for the units to be versatile and accommodating by reducing the need for truck transport and increasing onsite turnaround.

The objectives of stationary and portable plants are the same, but these have different operational goals for processing materials efficiently. As a result, stationary plants and mobile crushers require unique approaches to determine the best conveyor belt for their application.

For example, its hard to dispute that using a mobile crusher thats too small for the job will fail to meet yield requirements and reduce profits. Similarly, a crusher that is oversized will carry additional expenses to manage and wont add value, but it will add cost.

Many believe conveyor belting has a singular purpose: to convey material from one location to another. In reality, working with industry experts using advancements in rubber belting technology amplifies the value the component part can bring to the entire operation.

If a stationary plant is running multiple sorting conveyors at a variety of inclines and lengths, then using the same belt for each conveyor would not be optimizing productivity. However, a methodical approach in determining function over value for each conveyor will increase system performance overall.

In addition, manufacturers can build modern conveyor belts engineered with low-profile, high-strength inputs, meaning improved strength and durability in a thinner and more flexible design. This concept alone will increase efficiencies by reducing energy consumption, downtime and costly replacement parts.

A stationary plant can support longer conveyor systems due to the sites permanent structure and immobility of the stationary crusher units. A mobile unit will have much shorter runs but will see increased cycles and revolutions on conveyor belts.

Conveyor length helps to determine the specification requirements of a conveyor belt, with many of these properties relating directly to cost. For instance, longer conveyor belts see heavier loads with fewer cycles and require a stronger belt carcass with a robust connection method at the belt ends. Shorter conveyors require a more durable cover compound with increased flexibility on the carcass and at the connection of the belt ends due to the increased cycles.

Mobile units, particularly, require a conveyor belt with the strength to resist impacts, punctures and gouges, but also the flexibility to perform under accelerated cycles. Belt thickness and mass, in this case, become critical as mobile units have a limited power source to operate. Therefore, the belt needs to be light and flexible while maintaining high-strength properties to achieve peak-system efficiency.

Say two similar conveyors are running the same products with conveyor belts that also share similar performance specifications, but Belt A weighed 25 percent less in mass than Belt B. Energy efficiency on the conveyor with Belt A would decrease by 40 percent and reduce the wear and tear on the conveyor systems bearings and rollers. Belt A will be saving money even when its running empty in comparison to Belt B.

In the end, conveyor belting is one of the most expensive individual components of any conveyor system. Sourcing the most optimal belt for an application based on its requirements will more than pay for itself in the long run.

Baioni Environment, a division of Italian company, Baioni Crushing Plants, based in Le Marche, is launching its water treatment and washing products onto the Chinese quarrying market from its new branch office in Luoyang, Henan province.

This move helps in the internationalisation of Baioni, says Milena Bianchi, Baioni Environments marketing & communications manager. Having a market presence in China will also open a path to the Russian market. Russia has a long-standing history as a partner for Italian industries. But we need to make our products successful in China before we look at Russia.

As part of a big exports push, Bianchi says that Baioni is looking into potential co-manufacturing partnerships for its crushing, screening, water treatment and washing solutions in Egypt and the Middle East. We have a new dealer in Saudi Arabia, which is a big market for crushing, screening, water treatment and washing equipment. The UAE is another interesting market for us, and were also doing market research on Iran. Theres the Iran ConMin 2016 exhibition for the quarrying, mining and construction industries taking place in Tehran in November, and Unacea has organised a stand for Italian companies.

Another eye-catching export growth move for Baioni, a 90-employee company with a 15 million annual turnover, was the opening of a branch office near La Havana in Cuba in April this year. Baioni has been selling its products in the Caribbean island nation since 2012, having spent the previous six-years applying for a place on the islands approved foreign traders list.

Bianchi continues: Its a very strong market. Weve recently sold our fourth wash plant in Cuba, to a Cuban government import-export company thats part of the Ministry of Construction. The plant includes a BaiWash, a BaiPress [filter press] and a GRF fines recovery solution. The plant was delivered in July 2016 and is going to be used at the Cantera Habana quarry to produce sand, to wash aggregate products.

Previous Baioni sales in Cuba have included five MIL 1000 SP horizontal impact crushers to the same government import-export company that recently bought the Baioni wash plant solution. Baioni now also takes a commission from selling other Italian companies products into Cuba as part of their approved traders list status offering Bernardi Impianti asphalt plants and concrete batching plants to potential island-based customers.

Meanwhile, for its crushing, screening and washing plant model customers, Baioni is also now offering full Ma-estro plant automation. The sales agreement with the Rovereto, based in North East Italy, company was finalised earlier this year.

The first Baioni plant with Ma-estro automation is a 500 tonnes an hour plant, including a Baioni primary crushing unit with a MIP impact crusher, secondary crushing stage with MIS impact crusher and four screens, sold to an Algerian limestone quarry customer. The customer will mainly use the plant during the construction of new highways, explains Bianchi.

The second Baioni plant with Ma-estro automation is a 250 tonnes/hour plant, including a Baioni BP jaw crusher, a MIS secondary impact crusher and a MIL tertiary impact crusher, sold to an Algerian state company. The third Baioni plant with Ma-estro automation is a 200tonnes/hour plant, including a secondary and tertiary crushing stages, plus fines recovery GRF, washing and clarification plant. The automation covers both the crushing and screening and the washing and clarification section.

The Italian water treatment plant manufacturer is taking part in Strabags Brglen quarry renovation project. Phase one of its wet mud and aggregate waste water treatment plant installation, part of a joint venture works program involving Swiss and German companies, has seen the delivery and operational start-up of a FPTA 1620-80 (extendable to 100 plates) high beam filter press, a 235m clarifier settling tank (12.5m high x 6.5m diameter), and relevant ancillaries. The first project phase units are now treating water from a renewed aggregates washing plant.

For this customer, we are supplying a turnkey plant including piping, building, wiring, lighting and control panel for the drilling mud and aggregate waste water treatment plant. Nothing is being sub-contracted and it has been a big responsibility for us, explains Matteo Parolini, Tecnoidea Impiantis process engineer. Its the first time with one of our filter presses that weve used straight stainless steel hydraulic pipes to meet ever more stringent Swiss-German standard requirements.

Once installed, the Tecnoidea Impianti wet mud and aggregate waste water treatment plant will be capable of producing 200tonnes/day of sludge cakes, and recycling more than 3,000m/day of process water. With this joint venture, Strabag want Brglen quarry to be the reference quarry in Switzerland, says Parolini. Its one of the most significant current customer orders for Tecnoidea Impianti.

Tecnoidea Impiantis high beam filter presses such as the FPTA 1620-80 model for Strabags Brglen quarry renovation project have many features, including a sand blasted SA 2.5, zinc coated and epoxy painted frame; a multi-task trolley for plates opening, shaking and closing, plus clothes-washing nozzles and maintenance winch; a highly effective and non-intrusive automatic filtering clothes washing system; and filtering plates with external and visible outlet pipes to check the filtered water quality.

The Strabag Beton Brglen project represents the latest example of what has been a successful trading period for Tecnoidea Impianti in Germany, Switzerland and Austria, where its represented by the Metcam dealership. We have increased our market share in these countries and have a very good partnership with Metcam, says Parolini.

The European market is asking for more filter presses, especially where a site has previously had a big lagoon. Governments are saying that, from now on, building material producers must not waste water. You must recover it with a settling tank and filter press technologies. In some German areas, for example, producers are being fined 1 cent for each cubic metre of waste water discharged into a lagoon. The goal is to save space as well as recycle as much water as possible.

CDE Global (CDE) says it is increasingly witnessing a strategic shift by African quarry and mine operators who recognise that to gain an edge over their competitors, they need to offer the best quality sand to their customers. To target a better and more profitable market segment and increase return on investment, operators are starting to invest in more efficient sand and gravel washing systems such as the popular CDE EvoWash, which comes with its own electric control panel and is pre-wired.

Water conservation is a major concern in Africa. Northern Irish company, CDE, reports that savvy customers often combine their plant with a CDE AquaCycle, which recycles up to 90% of used water and runs for as little as R3/tonne. Mobile and compact CDE plants, with advanced no-spill transfer points, high quality components and reduced maintenance, offer a simple, one-touch solution.

Wayne Warren, CDE business manager for Sub-Saharan Africa, says: It is definitely worth looking beyond the initial cost of the equipment to see that in the long run, bucket wheel washers and screw classifiers are actually a money drain.

CDE says it understands that operators may not always feel confident to be left to their own devices once their plant has been installed. It offers a complete after care package to its customers, who benefit from the best after-sales service in the business.

Warren says: For operators located in very remote regions, we also advise stocking some spares on site to reduce risk in case of a breakdown or preventative maintenance actions. We have a wealth of experience in washing applications in various types of rock, so we are able to advise our customers on the best recommended spares package.

The CDE EvoWash range has, says CDE, revolutionised the sand and gravel washing industry in terms of efficiency, allowing customers to wash even the dirtiest of sands and aggregates thanks to its pinpoint accuracy in silt and clay cut points (usually around 75 to 63 micron).

The complementary CDE AquaCycle range enables user-friendly water management on site, with a thickener system that recirculates up to 90% of the waste water from the sand/gravel washing plant immediately for reuse. As a welcome bonus, the AquaCycle comes as a neat compact solution that can easily be added on to the sand washing plant.

Comprising an EvoWash unit and double or triple deck rinsing screens onto one compact chassis, the CDE M2500 was the first all-in-one washing solution to be created, with a capacity of up to 250 tonnes per hour. Its powerful upgrade, the M4500, with a capacity of up to 450 tonnes per hour, has recently been added to the M-Series range.

Paying particular attention to quality, performance and resilience, all transfer points, pumps and pipes are rubber-lined for maximum wear resistance. Screening media use Isenmann high-wear life PU panels and the Infinity range features a high frequency zero-weld screen design. Each machine is developed, made to order and tested at the CDE factory to satisfy every requirement set out by the client.

For quarry and mine operators who wish to optimise business opportunities, the flexibility of new sand washing opportunities and the range of applications available to them are set to revolutionise the African market. Nicolan Govender, CDE regional manager Africa, reflects on the future of the sand and gravel washing business: The concrete market in Africa is screaming for better quality sand. Currently, concrete producers are making do with a combination of dry crusher sand and natural river sand.

The gradings and quality of these sands fluctuate, especially the natural river sand in regions affected by drought. Washed sand and gravels are consistent and enable concrete producers to steady their mix designs and thus save on water and cement consumption.

Environmental pressure to stop river sand mining, as well as increased government duties on these mining activities will make natural river and plaster sand either scarce or too expensive for the local market.

The future of the African construction and mining sector is bright as we are starting to witness an upturn in the regions economy. Major infrastructural projects are currently in the pipeline and, as they commence in the near future, manufactured sand is going to become more prominent, with natural river sand resources becoming less attractive due to taxes or availability.

Sand and gravel washing allows you to sort and valorise construction and demolition waste, produce rinsed aggregates in demand for road projects and create a variety of sands for the glass and golf industries to name just a few applications.

In short, if, as an operator, you have a washing solution that covers both your customers needs for various grades of high quality sand and gravel and your own requirements for efficient, reliable and economical equipment providing high return on investment, you are master of your washing destiny, Govender says.

cement plant crushers manufacturers | jaw crushers | roller crushers | hammer crushers

cement plant crushers manufacturers | jaw crushers | roller crushers | hammer crushers

Cement Plant requires raw materials including calcium, silicon, iron and aluminum majorly. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum. These raw materials are large size rocks that need to be crushed in to smaller size rocks, Crusher reduces the size of large rocks to the size of gravels.

Raw materials from quarry are now routed in Cement Plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.

Hammer Crushers: Raw materials from quarry are now routed in Cement Plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.

Impact Crushers: Impact crusher is best suited for brittle hard to medium hard raw material crushing. In the impact crusher the feed material entering the crushing chamber encounters the impactor bars immovably mounted on the rotor and revolving with it at a circumferential velocity of 30-45m/second. The fragments are flung against the upper breaker plate, rebound into the crushing chamber, are again subjected to the action of the impactor bars, and so until they have been sufficiently reduced to pass through the upper gap onto the space between the two breaker plates. Here the process is repeated until the material is fine enough to pass through the second gap.

Compound Impact Crusher: compound impact crusher the two stages primary and secondary are combined in a single machine this is a dual rotor crusher in which the primary rotor runs at 35 m/ second and the secondary rotor (mounted below and to one side of the primary) runs at about 45m/ second circumferential velocity. The maximum product particle size is determined by the bottom gap formed by an additional ridged comminuting anvil plate. Compound crushers can accept feed lumps up about 1.5 m size reducing it to a product in which 95% is smaller than 25mm, corresponding to a reduction ratio of 60:1 achieved in a single pass.

Jaw Crushers: Jaw crushers are used for the primary reduction of very hard and abrasive admixtures for cement manufacture.The reciprocating motion of the crushing jaw of the double toggle (or Black type) jaw crusher subjects the material to a mainly compressive action. This machine is especially suitable for crushing very hard material fed in coarse lumps.

In the single-toggle jaw crusher the jaw moves not only backwards and forwards but also up and down, so that there is attrition as well as compressive crushing action. Crushers of this type are more suitable for the reduction of hard to medium hard material fed in smaller lumps.

Roller Crushers: Roll crushers are used for the primary reduction of medium -hard moist and abrasive materials such as marl, shale and clay. The feed is subjected to compressive and shearing action between a pair of counter rotating rolls, which may be either smooth or corrugated or provided with tooth like projections. The teeth give better bite to the feed and concentrate the action of the crushing force, enabling large and compact pieces of rock to be split.

Primary crushing plants can be equipped with gyratory crushers, jaw crushers, twin-shaft sizers, double-roll crushers, impact crushers or hammer crushers, depending on material properties and required throughputs.

We areable to provide mobile, semi-mobile or stationary plants and work together with our clients to choose the most suitable machine type depending on the mineral deposit, mine plan and mining method.

TAKRAF supplies fully-mobile crushing plants equipped with crawlers, wheels or walking mechanisms. Fully mobile crushing plants are directly fed by shovel or wheel loader and no haulage trucks are required.

A considerable number of mines around the world opt for a semi-mobile crushing plant. These plants are designed in such a manner that they can be relocated through the use of transport crawlers and/or multi-wheel trailers. Having the flexibility to relocate the crushing plant enables travel distances for haulage trucks and belt conveyors to be optimized during the life of the mine - all with a view to providing increased efficiency and flexibility to the mine operator. Choosing the optimal crushing plant location is an essential criteria for the reduction in the number of haulage trucks required and increase in operational efficiency.

For mines or quarries boasting mineral deposits with smaller extensions and/orwith short haul distances between bench and plant, a stationary crushing plant is usually the most optimal solution.Variations in production caneasily bematched by increasing or decreasing the number of haulage trucks.

Capital and operational costs of an operation depend directly on the material transport system. Conventional truck haulage as todays predominant means of material transport in surface mines are well established and provide excellent flexibility, however contribute up to 60% of the overall mining cost. Further to the potential operational expenditure (opex) reduction, IPCC systems also offer a number of other benefits to mining operations ranging from an increase in safety to reductions in dust, noise and greenhouse gas emissions, increased automation and bad weather downtime.

IPCC represents a viable, safer and less fossil fuel dependent alternative, comprising fully-mobile, semi-mobile or stationary crushing stations connected to conveyors and spreaders (for waste) or stackers (for ore) to transport material out of the mine.

crushing contractor tops up fleet with mobile jaws - quarry

crushing contractor tops up fleet with mobile jaws - quarry

Milbrae Quarries, a family-run quarrying and mining services business, has expanded on the local contract crushing market bolstered by the acquisition of two primary mobile jaw crushers suited to large-scale quarrying and mining operations. Damian Christie reports.

Milbrae Quarries is part of a privately owned group of companies that provide specialist services in quarrying, mining and concrete manufacture and supply across New South Wales, Queensland, Victoria and the Northern Territory. Its headquarters are based in Leeton, in the New South Wales Riverina district.

Established in 1969 as a small trades service business, PA Woods and Co has evolved into an important competitor in the mining services industry, providing contract crushing services to many big players Australia-wide.

The company name Milbrae comes from the first property that we bought near Leeton we commenced quarrying on the site, and when we started out our office was just a telephone on a pole in the middle of a paddock, recalled Chris Woods, the managing director of the company today. Nowdays the Milbrae site acts as our company headquarters and is home to our mechanical, engineering, transport and drill and blast teams.

The propertys original name was Millbrae with two L letters in it, but we are a race horsing family and my father, Peter Woods, insisted that we drop one letter out of it to get seven so thats why it has one L in it! Woods laughed. A number of famous racehorses had seven letter names!

While the business name may be short and to the point, it is attached to a very impressive organisation that has grown considerably over its three decades of operation. The Milbrae Business Group today employs more than 200 people across its businesses, and its assets include four fixed plant hard rock quarries, 20 road base pits, sand operations, a pre-cast yard, seven concrete plants and a fleet of mobile crushing plants and mobile concrete batching plants.

Having founded the business more than 50 years ago, Peter Woods now enjoys a well-earned retirement but continues to take an interest in the growth of the operations. Milbrae is actively managed by Peters two sons Chris and Brett. Chris is the companys managing director, overseeing the performance of the business as well as the mining services activities while Brett primarily drives the operational side of the business. Both Chris and Brett have sons involved in the business, ensuring that Milbrae will continue well into the future.

Milbrae is a vertically integrated enterprise. Its operations begin with being able to win material via in-house drill and blast or mechanical methods, crushing and screening the material either in its fixed plant operations or via one of its 17 mobile crushing trains, conditioning material via pugmills, transporting crushed material to users via its transport fleet through to producing ready-mixed concrete and pre-cast concrete panels for end users.

Chris Woods and his regional operations manager Scott Gillieatt estimate that on the hard rock quarrying side of the business, the annual output across the four sites would be in excess of one million tonnes of blue metal aggregates, and sand and gravel.

In addition to its company-owned operations, Milbrae has also built for itself a highly successful contract quarrying and mining business. Initially we designed and built three wheel plants consisting of primary and secondary crushers, all electrically driven to service our satellite pits, Chris Woods explained. We would mobilise our mobile crushing train to site, crush material to build our stockpiles to use for customer sales for a period of time, and the crushing equipment would then be moved to another site.

As a result, outside of the Riverina operations, the company has operated up and down the eastern seaboard including northern and southeastern Victoria, the whole of New South Wales, Queensland and the Northern Territory.

Our largest growth area that we have experienced was contract crushing for mine operators, with beginnings in the Mt Isa area utilising the company-built wheel-mounted crushing plants, Woods explained. Milbrae was initially involved with several smaller mining operators, before becoming involved with Xstrata and Glencore. It was the biggest increase we had in personnel and equipment. We have conducted contract mining operations at Mt Isa Mines, George Fisher Mine, Mt Cuthbert, Handlebar Hill Mine and then up in McArthur River Mine amongst others. This experience drove Milbrae to explore mining opportunities in New South Wales, and we have since conducted work at operations owned by Evolution Mining, Newcrest, Aurelia Metals, Tronox, CMOC, Alkane Resources and CBH.

Due to the logistics of operating remotely from its core region, the Milbrae Business Group established its own aviation service. It operates a turboprop Pilatus PC12 NG to support its operations throughout the country. Able to take aboard a complement of nine people, the aircraft can also be converted to handle cargo. The PC12 is able to operate from remote dirt landing strips commonly found in regional Australia and it has been essential in supplying parts to remote locations. Since COVID-19 began to impact our operations, the PC12 has been critical in allowing crews to be flown directly from home locations to mine sites without transiting hotspots, Woods added.

Milbraes growth has been impressive for a company that had humble beginnings, conducting mobile crushing for Leeton Shire Council 35 years ago. Today, it produces several million tonnes per annum output from its mobile crushing business and in excess of six million tonnes in its contract mining services division.

Milbrae regularly undertakes mobile crushing services for approximately 15 shire councils across New South Wales, Queensland and Victoria, along with a number of government departments and private entities.

Milbrae also contributed to the Hume Highway Woomgara Alliance, in which it provided mobile crushing works on a 9km dual carriageway and four bridges. It supplied about 290,000 tonnes of blue metal granite and 490,000 tonnes of regular granite for the project, with its mobile gear crushing at a rate of up to 320 tonnes per hour (tph).

The Riverina region is booming at the moment due to the great conditions in the agricultural industry, Woods added. There are a number of infrastructure projects underway, including major highway projects, feed lots, several solar farms as well as a rapid expansion being undertaken in the poultry industry, resulting in new chicken farms being opened here. Weve seen demand for road bases and concrete double over the past year, and weve probably never been busier in our history.

Any successful mobile contract crushing service is only as good as the equipment that it operates. Over the years Milbrae has used a variety of different makes of mobile crushing plant but since providing mining services, it has identified Metso Outotec as its crushing supplier of choice. The company has progressively upgraded its inventory so that Metso Outotecs renowned line-up of Lokotrack crushers now make up nearly half of its tracked mobile fleet.

Milbrae has worked with Tutt Bryant Equipment (TBE), the national distributor of Metso Outotecs Lokotrack and Nordtrack ranges of mobile crushers and screens, for the past seven years. The companys Lokotrack crushing fleet comprises two 63-tonne LT120 jaw crushers, one LT106 jaw crusher, four 43-tonne LT300HP cone crushers and seven 55-tonne LT1213S impact crushers.

Our wheeled crushing plants have proven themselves time and time again while undertaking mining projects, so we believe that the Metso tracked equipment complements the wheeled plants. The wheeled plants can undertake high volume static works, where feed material is readily available at the crushing location, such as being trucked from underground, while the tracked Metso equipment will undertake projects where flexibility in crushing location is required, such as crushing material located in large volume stockpiles, or at a moving face.

Woods said Milbrae was drawn to the Metso line-up because it has a strong reputation for reliability and robustness. We believe that Metso is one of the best producers of plant and equipment in the world. The early days were a little challenging but Tutt Bryant made a commitment to improve their back-up service and customer relations, and the relationship has come a long way, particularly with people like Wayne Kruger [Tutt Bryant Equipments technical sales representative for the Metso tracked plant] who had a hands-on crushing background. Thats always a big plus when people like Wayne have worked in crushing, it helps the sales person understand the key challenges that the customer faces on the ground.

Scott Gillieatt reiterated Woods comments. We recently had the opportunity to have three machines of similar capacity from different brands in our fleet crushing side by side on a client site, and the Metso outperformed the other machines, providing a higher and more consistent throughput, he said. The Metso machine was more robust, leading to Metso being our machine of choice. We also find that the parts have a longer service life, the wear is noticeably better as well, and this is coupled with the excellent service that Wayne provides.

The most exciting development for Milbrae is that it has recently purchased two Lokotrack LT130E hybrid mobile jaw crushers, which are suitable as a primary crusher in large-scale quarrying and mining operations.

For optimised energy efficiency for crushing operations, the hybrid LT130E can run on an external electrical drive or, in locations where this is not possible, an integrated 403kW Caterpillar C15 engine and 500kVA generator power package.

The LT130E incorporates Metsos renowned Nordberg C130 jaw crusher for large-scale quarrying applications. It is Metsos largest standard mobile jaw crusher, with a feed opening of 1300mm x 1000mm (51 x 39) for coarser feed material, and its heavy-duty design can manage the hardest materials. A small nip angle and kinematics ensure aggressive crushing along the whole length of the crushing cavity and for all rock conditions. The maximum output of the LT130E, in the right conditions, can be up to 1000 tph.

This large-scale unit is easy to adapt to existing processes. It is equipped with an adjustable hydraulic main conveyor and an advanced Metso intelligent crusher automation (ICr) control system. A wireless Metso ICr remote monitoring system or an interlocking cable can connect the unit to other Lokotrack crushing and screening plants. All maintenance locations are easily accessible, making daily routines easier and safer.

The LT130E can be optimised to move smoothly between sites. All the electric and hydraulic connections have quick couplings for easy disassembly. Optimised lifting points, along with user-friendly and safe hydraulic features, reduce downtime, while an easy split feature makes portability and set-up easier. For contracting purposes, the plant can be set up within a matter of hours.

The easy split advantage utilises hydraulic cylinders to lift the crusher and feeder above the chassis for transfer to a standard trailer. Like regular Lokotrack mobile plants, the chassis of the LT130E can be driven to the trailer via remote control.

As this article went to press, the two LT130Es were expected to be delivered and commissioned at Milbraes operations by March. The first of the units would go straight to work in Milbraes contract mining operations. The second, according to Woods and Gillieatt, is slated to be used at an internally owned site, allowing it to be rapidly mobilised for future mining projects.

While the LT130E has previously been trialled and demonstrated by TBE at Lima South Quarry in Victoria, these are the first units bought by an Australian quarrying producer. Wayne Kruger said this is an important milestone because Milbrae will have the two biggest Lokotracks in NSW. Besides mobile cranes, the LT130E is the biggest piece of mobile equipment that Tutt Bryant has ever sold.

The LT130E fits our model for contract mining and crushing perfectly, Gillieatt said. He added the LT130Es automation capabilities will also enhance Milbrae Quarries productivity in the pit. The LT130E can be remotely programmed by an operator in a nearby loader or excavator, which in addition to raising efficiency in the pit increases safety and removes risk for operators on the ground.

Our operators typically operate our current fleet of LT120s via remote from the excavator cabins, Gillieatt said. This provides an increased level of safety. We are all aware of the hazards of silica in mining, removing the need to have an operator physically walk over to the machine to change a setting greatly reduces their exposure.

Were also really happy with the service and maintenance side of things. The servicing comes into that as a complete package. The TBE technicians are in constant contact with our own mechanical department. Theyre great on the service, and their equipment is innovative and very user-friendly as well.

Kruger said that a major selling point of the Lokotrack plant for many quarry producers was TBEs assurance package. We provide regular technical assistance and warranty inspections. We provide an extended warranty with the equipment 10,000 hours or five years, whichever comes first. Tutt Bryant is also the only one that offers that type of extended warranty in the market.

With that sense of optimism, it is likely that Milbraes LT130Es and other Lokotrack mobile plant will continue to be a mainstay of the companys quarrying, mining and contract crushing businesses for many years to come.
