This machine has production efficiency. It applies bowl bearings and has higher accuracy storage; besides, it adopts a centralized lubrication system and a novel oil seals dust control system. The hydraulic cylinder or hand-driven winch can be used adjust the size of discharge opening. When materials which cannot be crushed enter the crushing chamber, spring safety device can protect the equipment from being damaged.
The series crushers are generally used for secondary or third-stage crushing. They are suitable for the crush of various ore and rock whose hardness is moderate, such as iron ore, copper ore, limestone, quartz, granite, sandstone and so on. The standard type is applies to the moderate crushing, the middle type and short type and both suitable for fine crushing; they are widely used in materials, water conservancy, chemical industry, and other fields.
