          Description: Ring hammer crushercharacteristics◆ Hammers are made of high abrasive alloy material.◆ Hydraulic driven large machines can be repaired easily◆ The high-powered machines driven by hydraulic couplers are characterized by soft starting and short-term resistance so as to protect the motor and spindle unit.◆ The spindle of forged alloy steel has been quenched and tempered.◆ The life of the screen bottom is extended by using cast steel material.I. PCH coarse crusher1. working principleMaterials are impacted and crushed through hammers driven by the rotating rotor of the machine. Then the impacted materials are compressed, sheared and grinded between the ring hammer and the crushing plate. At last materials of the demanded size are discharged through the screen meshes. Impurities of iron, wood and others are pushed into the iron removers by hammers and cleared at regular intervals.2. Application fieldThe machine can be used in heat-engine power plant to crush medium-hard friable materials like coal gangue, limestone, etc. in cooperation with coal mills. The grain size of the product is no more than 30mm,and the capacity is bigger.3.

Working principlesSimilar as the working principle of PCH type, materials are impacted and crushed through hammers driven by the rotating rotor of the machine. Then the impacted materials are compressed, sheared and grinded between the ring hammer and the crushing plate. At last materials of the demanded size are discharged through the screen meshes. Impurities of iron, wood and others are pushed into the iron removers by hammers and cleared at regular intervals. The only difference is that the screen mesh is narrowed to meet the demand of grain size.2. Application fieldThe machine is used to crush medium-hard friable materials like coal gangue, limestone, etc. to support fluidized bed boiler. The grain size of the product is no more than 10 or 13mm.3.
