Gary Mooney is at the controls of the McCloskey Jaw Crusher. Against the dusty backdrop of Ballycastle Quarry in Northern Ireland, this mighty rock crushing machine is moving in close again to collect more rock just blasted from the quarry face. Between the heavy duty Volvo Penta D13 engine and this mighty stone crusher, its a combination that matches industrial power and performance needed under extreme conditions.
After initial blasting, the hard rock from the quarry face is fed through the jaw rock crusher. This is no small task, and requires a durable and high power diesel engine. The stones are then lifted from a screener to make chippings that are used in the construction industry for concrete, tarmac and other purposes.
Over 20,000 tonnes of material is processed and crushed per month at this plant. The igneous basalt otherwise known or old solidified lava is used for high quality concrete in building foundations, roads and much more.
When the McCloskey rock crushing machine is not hard at work at the Ballycastle quarry, it can be found working on recycling applications. This powerful machine crushed 1,900 tonnes of material a month at a previous job site, which is enough for over 20,000 trucks loads to be used at various construction sites.
According to Neill Suitor, Engineering Director at McCloskey International, its the torque that sets the Volvo Penta diesel engines apart. The engines have great torque curves, which make a good difference to the running of our machines. They have the ability to keep the machine running under the tough conditions they work in.
The demands of one recent assignment in Arklow, County Wicklow required additional Volvo Penta horsepower, as Neill explains. The jaw crusher was originally built with a 360Hp D11 engine. The rock in Arklow was so hard we uprated the engine to the current 510Hp D13 and an uprated hydraulic drive to transmit an additional 100Hp to the crusher. The productivity increased significantly and the fuel consumption actually reduced.
The relationship between Volvo Penta and McCloskey International goes back several years, and McCloskey employs five different power ranges of Volvo Penta diesel engines in their range of jaw stone crushers. Neill explains the reasons behind the positive partnership. Volvo Penta work alongside us and guide us to the best solution and aid the initial design process right through to after sales support and backup. We are planning ahead together.
For machine operator Gary Mooney, the pleasure is in the performance and handling of the jaw crusher and diesel engine. It just makes life a lot easier. Were under a lot of pressure to deliver, so knowing that we have the right power onboard from the start makes operators like me very happy.
This robust diesel engine provides power to the McCloskey rock crusher machine with the high performance thats required grind hard rock down into a finer substance. The D13 delivers high power and torque at a low rpm, enabling heavy duty machinery to see more performance. It also gives the operator more comfort due to its low noise levels. In addition to high performance features, the off-road D13 engine cuts operating costs significantly because of its low diesel fuel consumption.
McCloskey International is an independent manufacture of mobile crushers, vibrating screeners, trommel screeners, stackers and washing equipment. The company was formed in 1985 with a headquarters in Ontario, Canada. Their powerful and robust machines can be found in a variety of machine industries: such as aggregates, mining, construction and demolition, infrastructure and roadbuilding, landscaping, waste management and recycling.
Kirpy are the stone specialists. Best known for the Kirpy Stone Crushers. They have been manufacturing and developing these Big Yellow Stone Crushers for decades. The wealth of experience they have gathered is beyond compare
With advances in Tractor development Kirpy have kept pace and developed ever larger and more productive crushers and ancillary equipment. Crushers are now capable of working over 500mm deep and processing thousands ofcubic meters of material per day harnessing the largest of today's tractors.
Kirpy machinery will be found processing rock and stone for sub bases in warehouse construction, recycling materials for farm roads and motorways alike, and on many of thenotablesportsfieldand amenity projects.
The Kirpy range of stone crushers are arguably the original and the best in the field. Designed to crush stones and rocks with a controlled processrather to simply smash. This controlled process gives users the ability to produced a determined size of stone to suit the particular application.
The longstanding BPS models have a huge range of production and can produced near sand like material for reclaiming areas for farm land or more often sports field work. The BPS can also accommodate large stone material and by using the adjustable anvil can produce engineering grade aggregates in-situ for road construction.
The BSC stone crusher is an evolution of the BPS for larger tractors and deeper work. Using the heritage of the open drum frame design, tough carbide hammers and ever reliable belt drive the BSC is built for decades of work. Working again in reclamation and roadways alike the Kirpy BSC crusher is a professional unit to contend with the toughest of stone.
The profile and mounting geometry of the forged solid steel legs means that rocks and foreign objects are pulled up out of the ground. This is as opposed to the leg merely being tripped over them. Bringing these stones to the surface allows for further efficient processing and or removal. By moving the ground it also aids drying and in turn reduces fuel consumption.
The heavy duty construction differs from agricultural cultivators with hollow or torch cut steel. A choice of packer rollers and similar options facilities use in agricultural cultivation where a strong cultivator is required.
Builtof a heavy duty construction the rippers have been utilised in major earthworks projects where rocks have precluded the use of standard techniques. Uses include the incorporation of lime in soil stabilisation projects drying out unsuitable soils.
According to the crushing force mode, the crusher machine divides into stone crushers and grinding machine.Whats the difference between stone crusher and grinding mill?General speaking, the former one is used to reduce the larger slab into a smaller size, various models of crusher are designed to maximize productivity at the lowest cost. The configuration of the suited crush machine is varied with different crushing stages in the complete crushing circuit, coarse crushing, medium-sized crushing, and fine crushing. The latter one of grinding mill machines are preferred to process fine and extremely fine material, grinding mediums include steel ball, steel rod, gravel, and metal lump so on. Some equipment is capable of crushing and grinding, such as self mill.Discrimination of the working principle1 Jaw Crusher. The movable jaw plate continually presses against the fixed die at a set time and force to squeeze the rock material caught in it.2 Cone Crusher. The inner movable cone rotates eccentricity and bumps the outer fixed cone, thus exerting strong crushing force on the ore material.3 Roll Crusher. The ore material is subjected to continuous crushing and impacting force between the two rollers.4 Impact Crusher. The ore lump crushed by the impact force of rapidly rotating moving parts.5 Ore Grinding Machine. The ore slab is crushed by the impact and grinding force of the grinding medium (steel ball, bar, gravel or lump) in the rotating cylinder. Rod mill, pan mill, ball mill, vibration mill, centrifugal mill, etc.Each kind of crusher has various models to suit different applications. Jaw crusher has the features of large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and economical operation cost. PF-I series impact crusher can crush materials with length less than 100 ~ 500 mm and its compressive strength can reach up to 350 MPA, which has the advantages of large crushing ratio. It is suitable for crushing medium hard materials, such as limestone in cement plant.
1 Adjustable fine crusherThe adjustable fine crusher mainly consists of a rotary part, guard plate, crushing chamber. The latest fine crusher equipped with a hydraulic device can be very convenient to maintain, save time cost.2 Jaw crushing typeJaw crusher, is the first choice for primary crushing equipment, with large crushing ratio, uniform product size, simple structure, the relatively small volume can be installed in the tiny space, etc. Therefore, it is widely used in mines, metallurgy, construction material, water conservancy and chemical industries.Compared with cone crusher, jaw type crusher has less investment, less finished flake and lower production cost. Compared with hammer crusher, the wear resistant parts have longer service time, high production efficiency and fewer maintain fees.The common jaw crusher has single toggle type and double toggle type, the former one also called as simple swing crusher, the latter one is called as complex swing crusher.3. Gyratory crusherThe gyratory crusher is a large scale crushing machine which uses the gyratory movement of the crushing cone in the crushing cavity to extrude, squeeze and bend the materials. When the shaft sleeve rotates, the crushing cone is moving in eccentric around the center line of the machine continuously. The productivity of gyratory crusher is higher than that of jaw crusher.There are two types of discharging material and overload insurance, one is mechanical type, by adjusting the nuts on the top of the main shaft to lift up or down the crushing cone, thus change the discharge outlet width, and by cutting the safety pin on the driving pulley to stop overload. Another way is hydraulic gyratory crusher type, by changing the plunger under the hydraulic oil volume can adjust the crushing cone position, thus changing the size of the discharge port.4 Cone crusherCone crusher widely used in the metal and mon-metal mines, cement, sand & gravel, aggregate, quarry, metallurgy and other industries. it is suited for fine crushing all kinds of ores and rocks with hardness 5 ~ 16, such as iron ore, Non-ferrous metal ore, granite, limestone, quartzite, sandstone, cobblestone, etc.The working principle of cone crusher is the same as that of gyratory crusher, but it is only suitable for medium-sized crushing or fine crushing. The requirements of uniformity of particle size distribution in medium and fine crushing operations are generally higher than that in the coarse crushing operation. Therefore, a section of the parallel zone should be set at the lower part of the crushing cavity. In addition, the rotating speed of the crushing cone should be accelerated so that the material can be squeezed more than once in the parallel zone.The crushing of fine crushing operation is larger than that of coarse crushing operation, so the loose volume after crushing increases greatly. In order to prevent the crushing chamber from blocking, the total discharging cross section must be increased by increasing the diameter of the lower part of the crushing cone without increasing the discharging opening to ensure the required discharging granularity.When the Simon Spring Safety cone crusher overloads, the cone-shaped Shell forces the spring to compress and raise itself in order to enlarge the discharge port and discharge the non-broken material. The adjustment of the discharge opening is carried out by the adjusting cover, and the adjusting cover fixed with the shell can be rotated to drive the shell up or down by the thread on the outer circle, so as to change the size of the discharge opening. The safety and adjustment mode of hydraulic cone crusher is the same as that of hydraulic gyratory crusher.Maintenance of cone crusher1, Ensure full load production, avoid too coarse product granularity.2, Optimize the cone crusher productivity by setting reasonable crushing ratio.3, It is necessary that equipped with an iron removal device.4, The spring cannot be too heavy pressured, the large pressure may occur shaft broke, light pressure may cause spring vibrating, influence the crushing efficiency.
Right way. First of all, you need to know the crusher materials, the maximum feeding size, finished particle size, handling capacity, crushing environment. With detailed information, JXSC will provide the stone crusher suitable for your production needs.
The humidity and hardness of different materials are different. The higher the hardness, the higher the degree of difficulty. For example, granite hardness, the jaw crusher, cone crusher, impact crusher will better. River pebble texture hard wear-resistant, roller crusher crushing effect is better. Brittle materials are more suitable for heavy hammer crushers, such as calcite.
2. Sorting machineWe can design the crushing plant flow chart when knowing the crushing demand and determine the primary, secondary and tertiary crusher use of which type. crusher. The next step is to choose the type of device. In order to improve efficiency, the general primary crusher processing capacity will be larger than the secondary.
1. Control material sizeThe crusher has a maximum feed size. When the feed particle size is too large to the equipment caused serious damage. Whether soft or medium-hard material, both cause different damage. If some of the materials are larger than the maximum feeding size of the crusher, the crusher is easy to appear stuck cavity, blocking phenomenon, affecting the aggregate production efficiency. 2. Correct feeding materialMany enterprises in order to increase the production capacity and blindly carry out the transformation of the bunker. It resulted in excessive feeding. And that feed too much, it will cause the material too late to break, and the broken material can not be discharged in time, resulting in blocking. Therefore, material cut-off and excessive feeding will affect the capacity of the crusher. 3. Maintenance and repairsThe daily maintenance and repair of the stone crusher is the key to the effective operation of the equipment. Check the machine regularly and replace the wear-out parts in time.
