Product introduction

Volcanic Rocks roller crusher has achieved a breakthrough in the equipment manufacture of aggregate production.  roller crusher has achieved a breakthrough in the equipment manufacture of aggregate production.  Volcanic Rocks 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.

Volcanic rock is a common ore, which has the characteristics of high hardness, high density and high wear resistance, so it is widely used in industrial production. For the sand making industry, the processing of volcanic rock is an important part. And roll crusher is a commonly used crushing equipment, which can crush volcanic rock and other hard ores with high efficiency, thus providing important technical support for sand making industry.

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.

Volcanic Rocks Crusher working principle

The Volcanic Rocks roller crusher operates through rollers. The volcanic rocks, 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.
