1. It is necessary to strengthen the iron removal work of the ore feeding. If the non-broken material falls into the pair of rollers, it will damage the equipment and cause a parking accident. Therefore, the iron removal installation should be installed in advance.

2. Pay attention to safety during the operation of the double roller crusher, especially when larger materials enter the crusher cavity, large pieces of material are easy to jump out of the crushing cavity and hurt people.

3. The viscous material is easy to block the crushing space. When dealing with the blockage, it should be stopped for disposal, and the ore should not be stopped during operation.

4. The double-roller crusher should not be overloaded, and electrical instruments should be paid attention to at any time.

5. After running the double crusher for a long time, due to the large wear of the roller surface, it will cause the product particles to be too fine. At this time, it is necessary to pay attention to adjusting the discharge port or repairing the equipment.

6. Strengthen the inspection of the double-roller crusher, refuel the smooth parts on time, and keep the equipment in a good and smooth state.

7. When placing the movable mounted chassis plane, dust and other materials should be removed, so that when the double-roller crusher encounters materials that cannot be broken, the movable bearing cannot be moved on the chassis, resulting in serious accidents.
