Double Roll Crusher Introduction

The two-roll crusher uses two sets of individually driven roller shafts to crush the material by the extrusion rolling force and grinding force generated by the relative rotation.

When the material enters the crushing chamber of the machine, the material is subjected to the action of the rotating roller shaft, so that the material is forced through between the two rollers. At the same time, it is squeezed and sheared by the roller shaft, and the material starts to chip and crack. Small particles along the tangent to the rotation of the roller pass through the gap between the two roller shafts and are thrown under the machine. Large particles of material that exceeds the gap continue to be broken into small particles.

Double roll crusher use

Double-roll crusher can be used in mineral processing, chemical engineering, cement, refractories, abrasives, building materials and other industrial sectors, fine crushing ore, rock and refractories below high hardness. Double roll crusher is more excellent than refractory crusher in refractory materials and mining industry. In recent years, it has been widely used in crushing steel grit and other industries.

The crushing production line supporting equipment includes:

Jaw Crusher (Smasher), Hammer Crusher (Hammer Break), Impact Crusher (Reverse Break), Compound Crusher (Compound Break), Roll Crusher (Double Roll Break), Roll Break Machine, Double Roll Crusher, Impact Crusher (Shock Break), Compound Pendulum Fine Jaw Crusher, Ring Hammer Crusher, PCL Crusher, Self Impact Crusher, Impact Crusher, Vertical Compound Crusher , Horizontal compound crusher, cone crusher, impact crusher, crusher, crusher, and vibrating feeder (feeder) used in crushing line, pendulum feeder, compound pendulum feeding Machine, Conveyor, Belt Conveyor, Conveyor Equipment, Linear Vibrating Screen (Linear Screen), Circular Vibrating Screen (Round Screen), Screening Equipment. Screening equipment, belt conveyors and other mining machinery crushing equipment.

Working principle and structure

1. This series of roller crusher is mainly composed of roller, roller bearing, pressing and adjusting device and driving device.

2. Adjustment of discharge granularity: There are wedge-shaped or gasket adjusting devices between the two rollers. The top of the wedge device is equipped with adjusting bolts. When the adjusting bolt lifts the wedge upwards, the wedge moves the roller away. The fixed wheel, that is, the gap between the two rollers becomes larger and the particle size of the discharged material becomes larger. When the wedge is downward, the two rollers of the movable roller become smaller under the action of the compression spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the material 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 particle size of the discharge becomes smaller. .

3. The drive mechanism is composed of two motors, which drive the drag roller through the V-belt drive to the sheave, and rotate according to the relative direction. When the material is crushed, the material passes through the roller from the feed port and is broken by rolling. The broken product is discharged from under the bottom frame.

4, for safety, the transmission part should be based on the actual situation to install the safety cover.
