The hammer mill also named hammer crusher, 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%. Liming heavy industry coarse powder mill (also called hammer mill or hydraulic Hammer Crusher) is one kind of new high efficient grinding machine. this mill is mainly used for coarse powder and small size of sand producing. the output size can reach more than 90% of 0-3mm.The coarse powder mill is one kind of new hammer mill ,it can be widely used in metallurgy, mining, chemical, cement, coal gangue, construction, sand, refractory material, ceramic and other industrial and mining enterprises, engaged in breaking and crushing the material in the operation. it is mainly suitable for crushing various soft and hard ore. whose compression strength is not higher than 320mpa (mpa).

　　This hammer mill crusher is applicable for both dry and wet crushing. 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%.

　　This hammer mill crusher machine 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.

　　How Hammer Crusher works:

　　In the hammer mill machine, the motor drives the rotor to rotate at a high speed through the belt, and on the rotor there are series of hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed are crushing them, the crushed products meeting the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushing area by the hammers for being re-crushed until they reached the required size.

　　hammer mill structure & features hammer mill(efficient crushing mill) consists mainly of frame, rotor, hammers and grizzly bars and other components.

　　1. high production capacity, high crushing ratio.

　　2. low power consumption, uniform particle size.

　　3. simple structure, easy to operate.

　　4. low investment cost, easy management.
