Double Roll Crusher

Double Roll Crusher is short for roll crusher or roll crusher. The roll crusher has simple structure and few over crushing phenomena. The tooth shape, size and arrangement on the roll surface can be changed with the material properties, and it can be used for medium and fine crushing of medium hard and soft ores. The counter roller crusher is mainly composed of roller, roller support bearing, pressing and adjusting device and driving device.

Outstanding advantages
lower production cost
The tooth ring of the roller crusher is equipped on the tooth roll, and the tooth sleeve can be replaced when it is worn to a certain extent, so as to reduce the downtime and production cost.
Safe and stable operation
The limited rectangle hydraulic coupling not only absorbs the impact force during crushing to make the machine run smoothly, but also plays a role of safety protection for the machine.
Reduce over crushing and loss
The dual function of crushing and screening reduces the over crushing and energy consumption of materials, prolongs the service life, and has the effect of shearing and tensile crushing.
Materials are not easy to block
The two rollers are non-uniform, non meshing and non constant speed operation, which can reduce the material blocking phenomenon of the opposite roller crusher.
Working principle
The roller crusher is mainly composed of roller, roller support bearing, pressing and adjusting device and driving device. A wedge or gasket adjusting device is installed between the two rollers, and an adjusting bolt is installed at the top of the wedge device. When the adjusting bolt pulls the wedge upward, the wedge will push the movable roller away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the discharging particle size becomes larger. When the wedge is downward, the gap between the two rollers becomes smaller and the discharging particle size becomes smaller under the action of the compression spring. The gasket device adjusts the size of the discharge particle size by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger; when the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller.
The driving mechanism is composed of two motors, which are driven to the grooved pulley by the V-belt to drive the roller and rotate in the relative direction. When crushing materials, the materials pass through the roller from the feed port, and are crushed by rolling. The crushed products are discharged from the bottom of the underframe. For safety, the transmission part shall install the safety cover according to the actual situation.
