Machine-testing Video

It is suitable for crushing sticky stone material into medium size. Roller crusher utilizes two rollers rotating in opposite direction to crush the material, which consists of motor, bracket, fixed rollers, movable rollers and springs. Most of its roller surfaces are glossy, and the bearings of the movable rollers can be moved along the machine frame and held against it by springs. Therefore, When a particularly hard object accidentally drops into the machine, the bearing can be moved out of the way to expel it. Furthermore, before the machine runs, the gap between the two rolls should be adjusted with shims to ensure the crushing size.

River pebble roller crusher working principle

The river pebble roller crusher operates through rollers. The pebbles, put into the machine through the inlet, are crushed by the squeezing between the rollers. The discharge size can be controlled by adjusting the gap between the two rollers. If the gap becomes larger, the discharged size becomes larger. While the gap becomes smaller by compressing spring, the discharge size also becomes smaller.
