Product description

  What is Rocks roll crusher

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.

Rocks is the rock with very high hardness, such as granite, quartz sandstone, basalt and other magmatic rocks, iron and calcium cemented conglomerate, sandstone, limestone, muddy greywacke, dolomite and other sedimentary rocks. Crushed hard rock is used in the construction of roads, tunnels, municipal buildings, airport runways, railways and so on.

Reasons for choosing us

  1. Compared with hammer sand making machine, roller crusher does not need to replace wearing parts.

2. The finished product features pretty shape, well gradation, low over-crushing rate and high output.

  1. Roller crusher is superior to hammer crusher and impact crusher, and the average service life ofitsroller sleeve is more than 2 years.

4. Roller skin contains high content of chromium, manganese and other rare metal materials. Adjustable discharge size.

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.

Rocks crusher is to use two sets of individually driven rollers to crush materials by squeezing and grinding shear force generated by relative rotation. The material falls into between the two rollers through the feeding port, and the finished products fall naturally after crushed by the roller extrusion. When encountering too hard or unbreakable materials, the rollers can automatically back off by the action of hydraulic cylinder or spring, so that the gap between the two rollers increases, and the hard or unbreakable materials fall naturally to ensure that the machine is not damaged, and the two rollers rotating in the opposite direction can be adjusted by the pressure of the hydraulic cylinder or spring to control the product’s The two rolls rotating in opposite direction can adjust the pressure of hydraulic cylinder or spring to control the granularity of the product.

working principle

The  double roller crusher performs crushing operations through rollers. The material enters between the rollers from the feed port and crushes the river pebbles through the extrusion action. There is a certain gap between the two rollers. The larger the gap between the two rollers, the larger the material output size. Under the action of the compression spring, the smaller the gap between the two rollers, the smaller the material output size. By changing the gap, the material output size can be controlled.
