The impact crusher is used for the fine crushing of metal and non-metal ores, cement, refractory materials, bauxite, corundum, glass raw materials, building materials, artificial sand making and various metallurgical slags, especially for medium hard and extra hard materials than other types of crushers are more effective.

For the maintenance and maintenance of the impact crusher, a brief summary is as follows:

1. Regularly stop the machine and open the observation door to observe the internal wear of the impact sand making machine. The wear degree of the central feeding pipe, cone cap, impeller upper and lower runner liners, circumferential guard plates, and wear-resistant blocks should be replaced in time after wear. When repairing and replacing the wear-resistant blocks, they should be replaced at the same time to ensure that the weight of the wear-resistant blocks is the same. It is strictly forbidden to open the observation door to observe the internal working conditions during the working process of the crusher to avoid danger. If the impeller body is found to be worn, replace it in time and find the manufacturer to repair it. Special attention, without the consent of the manufacturer, it is strictly forbidden to make the impeller by yourself.
3. The tension force of the transmission triangular belt of the sand making machine should be adjusted appropriately to ensure that the triangular belt is evenly stressed. The sand making machine is more effective;
4. When the sand making machine works for 400 hours, it should add a proper amount of grease. When it works for 2000 hours, it should open the main shaft assembly to clean the bearing. If it works for 7200 hours, it must be replaced with a new one. bearings.
5. The lubrication of the sand making machine is dry oil lubrication, the amount added is 1/2 to 2/3 of the bearing cavity, and an appropriate amount of grease is added every shift.
6. During the working process, because the sand making machine is a high-speed operating equipment, special attention should be paid to safety. The staff should stay away from the equipment. If it needs to be repaired on the machine, it must be operated after power off.
