The stone production line is a specialized production line equipment for manufacturing construction sand and stone materials, also known as the sand and gravel production line. In the stone production line, the relatively more frequently used equipment is the crushing equipment. Among them, there are jaw crushers for coarse crushing of stone, impact crushers for secondary fine crushing, or heavy-duty stone crushers for secondary shaping. Sometimes, according to process requirements, impact crushers, also known as sand making machines, need to be configured. Therefore, in the stone production line, Most of the maintenance work for the equipment is aimed at the crushing machine. Doing a good job in this part will greatly extend the service life of the stone production line equipment. The following is a brief description of the maintenance and upkeep of crushing machine equipment from three important aspects.

1. Bearing maintenance

The bearing part of the crusher is prone to damage and wears out significantly during use, so it requires regular maintenance and frequent oiling to increase the service life of the bearings.

2. Lubrication aspect

Regular attention and timely lubrication of the friction surfaces can ensure the normal operation of the jaw crusher and extend the service life of the equipment. The grease added to the bearing housing should be 50-70% of its volume. It must be replaced every three months. When changing the oil, the raceway of the bearing rollers should be carefully cleaned with clean gasoline or kerosene. When the toggle plate comes into contact with the toggle plate pad, lubricating grease must be injected before the crusher is started.

3. Daily aspects

To ensure that the crusher is in good technical condition and can be put into operation at any time, reduce the downtime due to faults, improve the integrity and utilization rate of the crusher, reduce the wear of the crusher, and extend the service life of the crusher; It is necessary to carry out regular maintenance and enforce it. The relationship between use, maintenance and repair should be properly handl d. It is not allowed to use without maintenance or only repair without maintenance.
