• Crusher Overview

• Hammer crusher also named hammer mill, and crushes materials by the collision between the high-speed hammer and materials. The hammer crusher 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.

• Crusher Features

• 1. Simple structure
  2. High crushing ratio
  3. High efficiency
  4. suitable for dry and wet crushing

• Working Principle

• Driven by the motor, the rotor of hammer crusher which consists 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.

• Crusher Application

• Hammer Crusher is widely used for medium or fine crushing for medium hard and brittle materials by departments of mine, cement, coal, building material, metallurgy, chemical industry, road construction, gas chemical industry and thermal power generation, etc. Coal gangue, coke, slag, limestone, phosphate rock, salt, whiting, gypsum stains, alum, brick and tile, etc. can be crushed by this equipment.
  
  The compression strength of the materials shall not exceed 100MPa, while the moisture content shall be lower than 15%. The equipment 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.
