After the user purchases a suitable sand and gravel sand making machine, choosing a suitable maintenance method can increase the use time of the equipment, which can be divided into the following points:
     1. Bearing: It bears all the load inside the sand making machine, and its good lubrication effect can increase the service life of the product and the operation rate of the product. It is necessary to add lubricating oil in the product in time to increase the service life of the bearing.      2. The use of wearing parts: the wearing parts are fast, and the wearing parts should be maintained in time and the worn parts should be replaced in time, which will not affect the use time of the product.
     3. The oil temperature of the bearing: When the oil temperature of the bearing shaft is too high, it should be s ped immediately for inspection to eliminate hidden dangers.
     4. Infrastructure requirements: The foundation construction at the bottom of the machine should be free of dust and debris. When the broken materials cannot be moved on the movable bearing, an accident will occur.
