The roller crusher is mainly composed of rollers, roller support bearings, pressing and adjusting devices, and driving devices. Its structure is simple. The roller crushers produced by our company mainly include powerful double-roll crushers, four-roll crushers and double-toothed roller crushers. It is widely used in medium and fine crushing operations in cement, metallurgy, chemical industry, electric power, coal and other industrial sectors. It mainly crushes various medium-hard materials such as limestone, slag, coke, and coal.
The double-roll crusher crushes the crushed material by dropping it between the two rollers through the feeding port, and the finished material falls naturally. When there are too hard or unbreakable objects, the rollers can automatically retreat by the action of hydraulic cylinders or springs, so that the gap between the rollers increases, and the extremely hard or unbreakable objects fall down, thus protecting the machine from damage. There is a certain gap between the two rollers rotating in opposite directions, and the particle size, particle shape and fineness modulus of the product can be controlled by changing the gap. The double-roller crushing sand making machine uses a pair of opposite-rotating round rollers or special-shaped rollers for crushing, and the four-roller crushing sand-making machine uses two pairs of opposite-rotating round rollers or special-shaped rollers for crushing operations.
Features of Roller Crusher
1. The toothed roller crusher mainly uses special wear-resistant toothed rollers to rotate at high speed to split and crush materials (traditional toothed roller crushers use low-speed extrusion crushing), forming a mechanism of high productivity.
2. The driving mechanism is driven by two electric motors, which are driven by V-belts to the sheaves to drag the rollers, and move and rotate in relative directions. When crushing materials, the materials pass through the rollers from the feed port, and are crushed by rolling, and the crushed finished products are discharged from the bottom frame.
3. Simple structure, convenient maintenance and low operating cost.
4. The gap of the discharge port is adjustable, which can ensure the discharge granularity according to the needs of users.
