Applied materials: coal, pebble, limestone, dolomite, granite, construction waste, pebbles, glass, cement clinker, basalt, iron ore, quartz stone, coal gangue, etc. Its advantages: high capacity, ability to handle wet, sticky feeds.

Roll crusher, as one of the most economical and practical crushers, is designed to handle the first and second crushing of friable minerals and stones such as coal, clay, coal gangue, limestone, slag, cement clinkers, and shale, etc.

According to the number of rollers, the FTM roll crushers can be divided into three types: single roll crusher, double-roll crusher, and multi-roll crusher. And the most common one is double-roll crusher.

Roll crusher is applied more widely than other crushers because of its small volume and cheap price. With the adjustable discharging system, it can be used flexibly in coarse and fine crushing processes of the industries such as cement, chemical engineering, electricity, mining, metallurgy, building materials, and others.

Roll crushers can adjust the wedge device between rollers to control the feed and discharge size of the machine. Also, it is equipped with a spring device to protect the crushing machine and avoid shutdown caused by overload and iron passing.

When the adjustable bolt pulls the wedge upward, the wedge pushes the movable roller away from the fixed wheel, then the gap between the two rollers becomes larger, and the discharge port becomes larger, and vice versa.

The gasket device adjusts the size of the discharge by increasing or decreasing the thickness of the gasket. When the gasket is added, the gap between the two rollers becomes larger, and vice versa.

The unique structure of rollers makes selective crushing of the roll crushing equipment. Since minerals fed are crushed along its internal friable crack, the finished products are uniform with the cube shape.

The minerals are crushed under the force of rollers and machine body, and ores smaller than the gap between roller and machine frame (of single roll crusher) or roller (of multi-roll crusher) will pass directly without repeated crushing.

With the supporting CPU, operators can control roll crushing machines and monitor gaps between rollers, and clean up the crushing cavity through the central control room, which will help save energy of 30% to 50%.

The main working parts of the roller crusher is the cylindrical rollers. The rollers are supported by the fixed and movable bearings, and they are relatively rotating which are driven by the motor. The materials are crushed by the friction of the rotating rollers, and the finished products are discharged from the gap of the rollers.

The spring is used to balance the pressure generated between the rolls. If there are non-crushed materials falling between the two rollers, the compression spring of bearings can be pushed to make a large gap so that non-crushed materials can be discharged immediately.

The quality of the crushers has a great impact on its price. The high-quality equipment will cost more in terms of workmanship, technology, materials, etc. Meanwhile, it will have a long service life, low failure rate, and better performance, and bring more profit to investors.

In 2019, Fote has exported a total of 39 roll crushers to India, Indonesia, Zimbabwe, Vietnam, South Africa, the United States, Pakistan, the Philippines and other countries, mainly for coal, bentonite, rare earth ore, limestone, aluminum, manganese and others.

Large numbers of iron ore mines are in operation in Orissa, India to meet theinternal and export demand of iron ore for iron and steel making. During the process of mining relatively lower grade iron ore containing 56-58% Fe is also being generated and stockpiled separately due to less market and industrial value. The accumulation of these lower grade lumps and fines are increasing day by day due to increase in the regular production of iron ore for steel industries. Simple washing of these low grade ores by scrubbing could not upgrade the iron content as evidenced from some laboratory studies.

Pelletizing plant iron ore involves different types of equipment. The main areas or processes are the hub, ball, induration and handling. The concentrator is where the ore is ground to a fine particle size typically 80 % - 45 micron powder and other impurities separated by magnetic separation and flotation . The area of agglomeration is where the powder ore is mixed with water, a binder and rolled in rotating drums to create spherical balls . The area of induration fact can be broken down into three areas: grid, oven, cooler. The grate surface is where the pellets are dried and the curing process is started. Pellets at this stage are more stable and can be stored in the oven without braking. The oven is used to conduct heat in the pellets to force the reaction throughout the pellet. In an effort to recover all of the heat that is present in the pellet after the oven, the granules fall into a cooling device .

Hematite is weak magnetic associated ore. The Mohs hardness of the hematite is 6. The flow of the technics would be: 1st stage ore washing--storage--1st stage crushing--2nd stage crushing--3rd stage crushing--2nd stage ore washing--storage--feeding ore into rotary kiln--magnetizing roasting--ore cooling--storage--ore milling--magnetic separation--dehydrate--fine ore.

iron ore price: have the bears got it wrong? | hellenic shipping news worldwide

iron ore price: have the bears got it wrong? | hellenic shipping news worldwide

Commodity forecasting is a difficult business at the best of times. Even the most sophisticated all-singing, all dancing supply-demand model cannot account for a myriad of imponderables. These can include weather events and environmental factors, operational outages and disasters, government policy changes (especially in China)and heavens above, a global pandemic.

Granted, there is always a crystal ball element to price forecasting. But in the case of key steelmaking raw material iron ore, analysts, consultants and industry experts, and often market players themselves, have consistently got the price outlook wrongtypically on the low side.

In fact, from practically the time your blogger started covering the iron ore and steel industryfrom Shanghai in May 2008, the month of Fortescue Metals Groups inaugural shipmenthe was told: Dont get excited by all the hype now, there will be a massive oversupply in a few years. Australian and Brazilian expansions, accompanied by millions of new tons from Africa, will swamp the market; scrap will increasingly displace iron ore; and prices will return to their historically low levels.

On the day this blog was written, the S&P Global Platts IODEX 62% Fe benchmark stood at $160.70/mt CFR China, 70% higher on the year before. So much for low prices! Forecasts are not carved in stone, of course, and are subject to revisions as market conditions change and new information emerges. But the consensus continues to be that iron ore prices will fall markedly in coming years. Most analysts see them dropping by roughly $5-$10/mt each year over the next four years, to an average of $95/mt in 2021, $85/mt in 2022, $$75/mt by 2023 and $70/mt in 2024.

At this stage, Platts does not provide a formal iron ore price forecast. This is therefore merely a personal view based on observing the market closely for almost 13 years. But heres why I think an overly bearish outlook on medium-term prices may be wrong:

There is little in the way of meaningful net new supply guaranteed to hit seaborne markets in the next 2-3 years. It is hard to see where the estimated hundreds of millions of tons of new supply over the next few years, built into some projections, are coming from. Yes, there are mine replacement in Western Australia projects (more on this later), and Fortescues new Iron Bridge magnetite project. Fortescue also has plans to lift capacity at Port Hedland by an additional 20 million mt/year, while BHP has similar plans to increase throughput at the port. But planned capacity and actual production are two different things.

Many were skeptical (including this author) when Rio Tinto and BHP routinely trotted out the view a few years back that China would produce 1 billion mt of crude steel by 2025-2030. When Chinese steel output seemed to go into reverse from 2014, the view was that Chinese steel consumption and output had peaked. The party was over! Instead, things took off again in 2016, helped by some capacity reduction and a property construction boom. Bumper profits incentivized Chinese mills to build new capacity and lift output. In 2019, China produced 996 million mt of crude steel and this year the 1 billion mt mark will be breached. As it turned out, Rio Tinto and BHP were 5-10 years too late in their predictions. Platts expects Chinese steel production to keep growing at 1%-2% in the next couple of years. The demand side of iron ore will remain extremely strong and it wont just be coming from China (see below).

Despite its increasing sophisticationautomated logistics, use of big data, control centers 1,500 km away from the mine site, etcmining is still essentially about digging holes and transporting material on trains and ships; there are many things that can go wrong along the supply chain. Further, the iron ore hubs of Australia and Brazil happen to be located in regions that suffer cyclones and heavy rains every year. Damage to facilities is not uncommon.

Theres not much point building ambitious volumes into a supply-demand model when companies keep missing their current year targets. In October, Vale said it would reach 400 million mt by early 2023 at the latest. In December, the Brazilian company downgraded its 2020 target from 310 million-330 million mt to 300 million-305 million mt. Rio Tinto has been beset by operational issues this year, and has downgraded its full-year production guidance more than once. In fact, Rio Tinto and BHP have both flagged maintenance work in calendar Q4 as being likely to impact iron ore production. Anglo American Kumba has said annual port and rail maintenance at its South African operations will see it achieve the lower end of its production guidance this year.

Following on from the above point, there are a number of significant mine replacement projects due to start in the Pilbara region of Western Australia. Fortescues new 30 million mt/year capacity Eliwana mine has just produced its first ore. Next year, Rio Tinto will start its new 43 million mt/year Koodaideri mine to keep up its flagship Pilbara Blend product, as supply at older mines is depleted. BHP will launch its new South Flank operation in 2021 that will replace the 80 million mt/year Yandi mine. In other words, a lot of tons of iron ore depend on successful tie-in work, commissioning and ramp-up of new projects. Will the majors maintain overall production and export volumes as new operations are brought online? Given the way the market often freaks out (like right now) at any potential supply shortage, any announced delays could see prices spike.

Quite simply, the iron ore industry cannot afford another Samarco, Brumadinho or Juukan Gorge. It would be hysterical to say such an important industry is in the last chance saloon with investorsbut the fate of outgoing Rio Tinto CEO JS Jacques shows the level of scrutiny the sector is now under. Investors have walked away from thermal coal, and many are snubbing metallurgical coal. Cleaner sectors have growing investor appeal, which is one reason for the current buzz around hydrogen. S&P Global Ratings includes ESG factors in its criteria for evaluating companies and they are likely to play a larger role over time. Many of the miners have now put in place measures to ensure rigorous consultation with traditional owners and First Nation communities. A more careful and diligent approach to developing and expanding iron ore mines could see longer project timelines.

There is a massive amount of new integrated steelmaking capacity planned for Southeast Asia in the next few years. Most of the mooted new projects will probably get no further than the drawing board. But one would have to think some new capacity will be builtespecially as the lions share is being funded by Chinese companies, which could potentially benefit from Belt & Road Initiative borrowing terms. In the meantime, established mills such as Vietnams Hoa Phat are adding blast furnaces. Over time, the region could pick up any fall in demand for iron ore from China, Japan and South Korea.

Taken together, these drivers point to upward support rather than downward pressure in the iron ore market, in the short-to-medium term at least. But of course, my crystal ball is just as cloudy as everyone elses Source: Platts
