The impact crusher has a wide range of uses. It not only promotes the rapid development of granite mining and processing, but also applies to the production of concrete. Of course, the impact crusher is well known in the mining of limestone.

Limestone is used to make glass, soda ash, caustic soda, etc., iron smelting uses limestone as a flux to remove gangue, and quicklime as a slagging material to remove harmful impurities such as sulfur and phosphorus. In daily life, limestone is burned to produce relatively pure powdered calcium carbonate, which is used as a filler for rubber, plastic, paper, toothpaste, cosmetics, etc. In agriculture, lime-sulfur mixture Bordeaux mixture and other pesticides are prepared with quicklime. The application of hydrated lime in the soil can neutralize the soil The acidity of the soil improves the structure of the soil to supply the calcium required by plants. Brushing the trunk with lime slurry can protect the trees. The chemical industry uses the chemical processing of limestone to make calcium chloride, calcium nitrate, calcium sulfite and other important calcium salts. Limestone in Xinjiang Province, China The reserves are abundant. In view of the huge economic value of limestone mining, in recent years, the limestone powder processing industry has been vigorously developed and good economic benefits have been achieved.

The work of impact crusher When the stone material falls directly from the upper part of the machine into the high-speed rotating turntable under the action of high-speed centrifugal force, it will cause high-speed collision and high-density crushing with another part of the flying rocks around the turntable in an umbrella manner. After the stones hit each other, they will A vortex motion is formed between the turntable and the casing to cause multiple mutual impacts, friction, and crushing, and it is discharged directly from the lower part. It forms a closed circuit for multiple cycles, and is controlled by the screening equipment to achieve the required particle size.
