When the crusher has been running for some months or some years, the raw materials may become harder to crush or a higher output may be needed. The MHC twin shaft breaker can then be adjusted in several ways.

The size of the drive pulleys may be altered to achieve a higher throughput or a higher torque.

Minor adjustments of the output size can be made by altering the synchronization of the two rotors.

3. Easy Maintenance

The Twin shaft breaker has four bearings that are continuously lubricated by a grease pump placed in a cabinet. The excess grease in the bearings is discharged inside the machine and ends up in the crushed product. The barrel contains grease for several months and the system is monitored by sensors that trigger an alarm if a malfunction occurs or the grease barrel is empty.

The condition of the crusher wear parts (toothed discs in rotors and cleaning teeth) is easily monitored by taking a glance inside the breaker. The breaker is moved into maintenance position by lowering the wheels at the corners. Tools and lifting yoke are supplied together with the breaker to facilitate quick and trouble-free maintenance, including replacement of wear parts. If the humidity of the coal is greater than 15%, Double Roll Crusher for coal is more appropriate.
