Hammer Crusher

  Hammer crusher or hammer mill is used to crush mid-hardness and weak corrosive materials, whose compressive strength is under 100 Mpa, and water ratio is less than 15%. Hammer crusher possesses qualities of simple structure, large reduction ratio, and high-efficiency. Both Dry and Wet Process are available.

Hammer crusher is widely used in mining, cement, coal, metallurgic, construction material, road building, and Petroleum & Chemical industries. The hammer crusher can be used not only in the crushing and sand making production lines, but also the mineral processing production line, taking the place of cone crushers.The hammer crusher can be also used for crushing chips and paper with fiber structure and strong elasticity and ductility, or recycling asbestos fiber by crushing wastes of asbestos cement, etc. Gap between the gratings are adjustable to change grain size of the discharge, so as to meet different requirements of the customers.

  Hammer crusher working principle

Driven by the motor, the rotor of hammer crusher which consist of main shaft, disk, pin shaft and hammers rotates at high speed in the crushing cavity. Raw materials enter the cavity through the feed opening. Materials in the cacity are blowed, impacted and ground by the hammer. Below the rotor is the sieve plate, which screens the materials.

Materials in the hammer crusher that reach the required size can be discharged from the sieve plate, while the oversize materials will be left and crushed again until reach the standard size. The final product size of the hammer crusher can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.
