1) Iron for ore feeding should be strengthened. Non-fragments (bits, etc.) falling into the rollers will damage the mobile crusher, resulting in parking accidents. Therefore, the iron removal device should be installed before the crusher.

2) Viscous materials are easy to clog the breaking space. Stop processing should be done when dealing with the clogging fault. It is not possible to poke ore in operation.

3) When the treated materials contain large blocks, it should be noted that large blocks of ore are easily squeezed out of the crushing space to prevent injury or damage to equipment.

4) When the mobile crusher runs for a long time, the wear of the roll surface will cause the product to be too fine. At this time, attention should be paid to adjusting the ore discharge port or to the maintenance of the equipment.

5) Strengthen the inspection of mobile crusher and lubricate parts of equipment.
