Hammer crusher is developed for both dry and wet crushing of brittle, medium-hard materials such as limestone, coal, filings, iron eyebrow, etc. the maximum compressive strength of material is not more than 1500kg/cm2.  The hammer crusher is usually applied to the mining, cement, coal, metallurgic material, construction material, road building, and petroleum & chemical industries etc. 
2.Features

1. The body uses gas to protect the welds, through the technological performance of vibrating expiration, the toughness of structure is stronger
2. Rotating parts are processed and with quality-adjusting treatment by the numerical control center. The toughness is higher.
3. The hammer plate was processed by the high-toughness materials, through the overlaying treatment, the appearance is more anti-resistance.
4. The hammer head use the pure high-chromium alloying material. The tensile strength and the wear-resisting property is better.
5. The screen board and the protecting board use the design idea, the anti-hit, the resistance to wear is stronger.
6. The outlook design and the strengthened intrinsic quality make the performance to be more superior.

In the hammer crusher, 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.
4.Application

Hammer crusher machine are usually serve as secondary crusher. They are widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc.
