La description

primary hammer crusher application:
●PCH series ring hammer crusher is a machine which is utilized to crush the coal, it is the most suitable to crush each brittle materials, like coal, gangue, coke, slag, red sandstone, shale, loose limestone, etc.
●The compressive strength of the material does not surpass **0MPa; the moisture content does not surpass *5%.
●It has the following features: saving the energy, guaranteeing the discharged material size, the higher production efficiency, the lower noise, the less dust and so on. 
●Otherwise, the discharge opening can be adjusted according to the customer’s requirements. Working Principle:
PCH series ring hammer crusher is an impact rotor-type crusher with hammer ring. The materials are impacted and crushed by the high-speed rotating hammers after entering the chamber. The crushed materials get the impetus energy from the hammers, and then they will impact on the crushing plate. After the secondary crushing process, the materials fall on the sieve plate. Then the materials are crushed again after being sheared, extruded, and grinded, and then dropped out. Unbroken matters enter the metal collector, which are cleaned periodically.
