Hammer Crusher
Hammer and rotor disc
The hammer and the rotor disc are made of ultra-high manganese steel. By casting with abrasion resistant alloy rods, the service life is over 1.5 times that of common alloys.
Housing/Casing
All the inner surfaces of the housing that come into contact with the mineral materials are protected by liner plates in order to prevent wear.
Crushing plate
The crushing plate is placed directly in front of the rotor, and the material size to be delivered is determined by the gap between the crushing plate and rotating motor circle. It is made of a high manganese steel through a casting process, with the maximum clearance designed to be the same as the maximum size of the discharged materials.
Grate
The grate is composed of cast high manganese steel grate bars. These grate bars are mounted at bottom of the rotor, covering almost all working surfaces with laying in a circumferential direction, thus wet materials can be easily removed.
Security door
By outfitting this equipment with a security door, foreign materials will be immediately discharged using centrifugal force, with the door automatically closing to prevent unprocessed materials from accidentally being removed. The security door can usually be left open when the required discharge size is large.
- If there are large sized materials that cannot be crushed by the hammer in the first round, the belt pulley mounted on the shaft end will return to the rotor disc in order to ensure a stable rotor operation.
- Due to its large feeding size design, a variety of minerals can be fed into crusher body.
- The materials can be crushed once by hammer crusher, and then transferred to the grinding process.
- The hammer is designed with an entire rotation function, so the material impact on the rotor is significantly decreased.
- The crushing chamber is adjustable, thus reducing abrasion on wearing components.
- The rotor of this hammer crusher features a great inertia and high rotating speed, and the linear velocity of the hammer reaches 30~35m/s.
