The impact crusher used in limestone processing

The usage of impact crusher is quite wide. It is not only helpful in the development of mining and processing of granite, but also can be applied to concrete making. Of course, the impact crusher is most well know in limestone mining.

Limestone is used in the manufacturing of glass, soda ash and caustic soda etc and it can also be used as flux in the the ironmaking to eliminate the gangue. What’s more,  being used as slag materials, the limestone can remove sulfur, phosphorus and other harmful impure materials. In the life, limestone can be processed to make pure powdered calcium carbonate, and can also be used as the filling materials of rubber, plastic, paper, toothpaste and cosmetics etc. For agriculture, the quick lime can be used to compound lime sulfur bordeaux mixture and fluid of pesticide etc. The application of hydrated lime in soil can improve soil structure by counteracting the soil acid and supplying calcium element needed by plant. Trees can be protected by tree trunk being brushed with lime. In the chemical industry, using limestone can produce calcium chloride, calcium nitrate, calcium sulfite and other important calcium salt. China's xinjiang province has rich reserves of limestone. In view of great economic value of limestone mining, the attention has been paid to the development of lime stone powder processing industry in recent years, which has achieved good economic benefit.

The working principle of impact crusher is as follows: When the materials enter the field of the hammer, it is impacted by the hammers, thrown onto the impact plate, and crushed. The stuff springs from the impact plate, is impacted by the hammers again, and thrown onto impact plate. This process will last until the stuff meets the requirement and falls from the machine. Adjusting the distance between impact frame and rotor frame can change the shape and size of the output.
