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.

The toothed roll crusher has a small volume, large crushing ratio, low noise, simple structure, and high productivity. and products are sold to more than 120 countries and regions around the world. Such as South Africa, Zimbabwe, Zambia, Algeria, Australia, Malaysia, Nepal, Ethiopia, Saudi Arabia, the Philippines, Mexico, Brazil, and other countries
Nearly 40 years of mining equipment technology and experience make the toothed roller crusher a simple, rational and compact structure. Rigorous quality management guarantees the superior quality of each machine.
Compared with other types of crushers, this series of crusher has many advantages such as big crushing ratio, low noise, low vibration, low energy consumption, small coverage size, simple and convenient maintenance.;
Double roll crusher is mainly used for the crushing of medium or lower-hardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production. Roll crusher machine has a theoretical maximum reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher, the absolute smallest size one could expect from the crusher is 1/2 inch. Toothed roller crusher will only crush material down to a minimum particle size of about 10 Mesh (2 mm). Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Roll crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)
Tooth Roll Crusher is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, etc.
Toothed Roll Crusher is worked by making two toothed roll rotate oppositely under the action of two pulleys on two sides of crusher, which driven by one motor or some motors. Thus the materials reaching the required size fall and discharged automatically, while the ones larger than two toothed rollers still left to be crushed until they reach the required size.A roll crusher using compression to crush, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times of the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.
