Hydraulic cone crushers are used in mine crushing section and aggregate crushing production lines. The engineer introduced how to use the hydraulic cone crusher. In addition to the operation of the equipment and the properties of the material itself, the feeding process conditions and the layout of the feeding equipment will affect the operation of the hydraulic cone crusher. The crushing cavity of the hydraulic cone crusher is filled with materials, which can not ensure the operating efficiency of the supporting motor, but also reduce the number of unqualified products due to the close contact of the materials in the crushing cavity. The crushing cavity of the hydraulic cone crusher is filled with materials, which not ensures the particle shape, but also reduces the phenomenon of serious local wear of the lining plate and ensures the utilization rate of the lining plate. It can be seen how important it is to feed the hydraulic cone crusher with full silo.
