Ring Hammer Crusher is a kind of  impact rotor type crusher  which have a ring hammer.Ring Hammer can not only switch along with the rotation, but also rotate around the hammer pin. When the material enters into the crusher, it can be crushed by the ring hammer which is revolved by the high-speed motor, at the same time the material obtained the kinetic energy and rushed at the impact plate receiving the second crushing process, then falls on the screen sieve and be cut, extruded, and grinding by the ring hammer. At last the materials that come up to the standard can be discharged by the machine. Uncrushable material enters into the metal collector and should be eliminated regularly.
Through the replacement of the sieve plate, the discharge size of materials can be adjusted. The gap between the rotor and the sieve plate, can be adjusted by the mechanism.
