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.

For saleare the 911MPE-24, 911MPE-44,911MPE-56 and911MPE-6100 both Laboratory Crushersare designedfor fast and efficient crushing ofmedium-hard rocks and ores. It iscompact and of rugged construction forgeneral laboratory or small pilot plantoperations. These small Lab Crushers have a wide range of applications acrossmany industries such as mining, metallurgical industry, coal, geology andchemistry. Advantages:
Under the dual role of subsidies for new energy vehicles and market promotion, lithium manganate will start from medium and high-end materials. The most suitable for the application of lithium manganate to pure electric bus models is Beiqi New Energy, followed by Xiamen Jinlong and CSR. In addition, Zhongtong Bus, Yutong Bus, Yangzijiang, Ankai Bus, Shenlong, Yaxing Bus, etc. all began to use lithium manganate in pure electric bus models. Since the second half of last year, many lithium manganate enterprises have expanded their production capacity, such as Hunan Haili, CITIC Dameng, Hebei Qiangeng, Zhongtian Light Source, Tianjin Tongyi, etc., and the products have also turned to medium and high-end dynamic lithium manganate. development of. At present, there are nearly 20 lithium manganate enterprises with an annual output of more than 1,000 tons. With the replenishment effect of new energy vehicles this year, and the rapid advancement of lithium manganate technology, the products will gradually be affected by the car enterprises. Favor. Manganese-based batteries are one of the most suitable choices in the future of electric vehicles. Xingheng Power will adhere to the application of manganese-based batteries in commercial vehicles, especially logistics vehicles. There are also listed companies to expand the original lithium iron phosphate battery project to the direction of lithium manganate. Golden Eagle shares previously said on the interactive platform that the company is actively adjusting the original lithium iron phosphate battery project to the direction of lithium manganate. The industry believes that if lithium manganate can maintain its original advantages, and through technological innovation, increase cycle times, increase capacity, enhance high and low temperature performance, etc., will have a place in the new energy market segment.Get in Touch with Mechanic
