Product introduction

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.

Reasons for choosing us

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

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

3. Iron ore sand making machine 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.

Working principle

The Roll 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.
