Application

Grade Crusher is mainly used to crush raw coal in coal mines and coal preparation plant. It can also be used to break other brittle materials whose hardness is lower than 10(Protodrakonov scale of hardness)

Working Principle  

Through the feed opening, the raw material fall into the crusher between the two rollers, after crushing, the final products drop out naturally. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and the hard or unbreakable material so as to avoid the machine being damaged. The clearance between the two rollers can be adjusted to change the sizes of final products

Features  

1. Their initial cost is lower

2. Our Grade Crusher is durable and strong

3. Design is simpler and easier to repair

4. Taking electric and torque converter double overload protection to improve its reliability and safety.

5. Fixed spacing between 2 tooth rollers makes it stable to discharge.

6. Using PLC to control the whole procedure, increase its automation level.

7. All tooth roller bearings are lubricated concentrated with lubricating grease pump, more convenient and faster.

8. Reasonable design for the shape of tooth plate and high-qualified wear resistant material extents its working life.
