Product description

What is Roll Mill Crusher

In line with the development of the construction industry and aggregates, river pebbles, as an important aggregate, are in increasing demand. The river pebble can be crushed into sand which is an essential industrial raw material. And, the river pebble sand making machine is critical to the utilization of river pebbles. Then it is apparent that ordinary sand making machine no longer meets the needs of customers. However, we wondered which sand making machine enjoys both high quality and high output? HSM river pebble Roll Mill Crusher has hit the market! We can also call it river pebble crusher.

River Roll Mill Crusher has achieved a breakthrough in the equipment manufacture of aggregate production. River Roll Crusher,also named as double roller crusher or roller sand making machine, runs by driving two motors and two pairs of rollers to grind the material fed. Double roller crusher can operate crushing material less than 80mm as well as the finished product size 50 mesh-20mm.

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.

Roll Mill Crusher working principle

The  Roll Mill 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.

River Roll Mill Crusher is divided into several kinds: Spring fine crushing sand making machine, cardan shaft drive roller crusher, hydraulic fine crushing sand making machine.You can choose the machine according to your budget and the facts.

working principle

The double roll crusher uses two independently driven rollers that rotate in opposite directions, generating extrusion and shearing forces to crush materials. Feed material enters through the inlet, is crushed by the rollers, and discharged naturally. If unbreakable or oversized materials are encountered, the hydraulic cylinders or springs automatically retract the rollers to widen the gap, allowing the material to fall through safely. The discharge size is adjusted by controlling the hydraulic or spring pressure.
