Product introduction

What are the models of weathered sand making machine?

We recommend a variety of double roller sand making machine models, such as 1510 type, 1080 type, etc, with production capacity 5-450 tons per hour.

Our machine features high efficiency as well as one-touch start-stop for sand plants’ specific requirements.

Weathered rock  roller crusher has achieved a breakthrough in the equipment manufacture of aggregate production. Weathered rock  roller 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.

Reasons for choosing us

1. Compared with hammer sand making machine, yellowish brown stone 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.

3. Yellowish brown stone 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.

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.

Weathered rock  roller crusher working principle

The Weathered rock  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.
