Plastic crusher maintenance knowledge

It is believed that when people use plastic crushers, there will be small problems such as loose screws. Today, let us talk about the usual maintenance knowledge of plastic crushers.


The ventilation position should be placed mechanically to ensure that the motor heat is dissipated before extending the life of the plastic crusher.

Regularly check the tool screws. After the new machine is used for 1 hour, fasten the tool with a tool and fix the screw of the knife to enhance the stability between the blade and the tool holder.

Bearings should be regularly lubricated to ensure lubrication between the bearings.

In order to ensure the sharpness of the tool incision, the tool should be checked frequently to ensure its sharpness and reduce unnecessary damage to other components caused by the blunt blade.

Before starting the second time, the remaining scraps in the machine room should be cleared to reduce the starting resistance. The inertial hood and the pulley cover should be opened periodically to clear the ash outlet below the flange. The powder discharged from the crusher chamber enters the bearing of the rotating shaft.

When the tool is changed, the clearance between the moving knife and the fixed knife is more than 20HP crusher 0.8MM, and the following 20HP crusher 0.5MM is better. The thinner the recycled material, the larger the gap can be adjusted.

The machine should be well grounded

Check the belt regularly for relaxation and tighten it in time.

When the new machine is in use, it shall be shut down every 4 days. The scrap room shall be opened and the nut of the blade shall be tightened one by one with a wrench.

When the plastic crusher is not used for a long time, it should be marked with anti-embroider oil to prevent rusting of the cutter.
