Uses of the new quarry crusher:

The new quarry crusher is widely used in the medium and fine crushing fields of various ores, cement, refractory materials, calcined bauxite clinker, emery, glass raw materials and other high-hardness and extra-hard materials. It is even more commonly used in the crushing of machine-made construction sand, stone materials and various metallurgical slags. Compared with other types of crushers, it has higher output and efficiency.

Working principle of the new quarry crusher:

Regarding the working principle of the impact crusher, to put it simply, it is the principle of stone hitting stone. The material enters the crusher from the feed hopper, and the material is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor and is rapidly accelerated inside the impeller. Its acceleration can reach hundreds of times the acceleration of gravity. Under the action of high-speed centrifugal force, it is then ejected at a speed of 60-70 m/s from three evenly distributed flow channels of the impeller. It first produces high-speed impact and crushing with a part of the material falling freely around the distributor, and then together they impact the material lining layer in the vortex cavity, are rebounded by the material lining layer, impact obliquely upward to the top of the vortex cavity, change their direction of motion again, and move downward at an angle. The material emitted from the impeller flow channels forms a continuous material curtain. In this way, a piece of material is subjected to two or more probabilistic impacts, friction and grinding crushing effects in the vortex crushing cavity. A closed-circuit multiple cycle is formed, and the required finished product particle size is controlled by screening equipment. The crushed material is discharged from the lower discharge port. Forming a closed circuit with the circulating screening system, generally three cycles are enough to crush the material to below 20 mesh. During the entire crushing process, the materials impact and crush each other by themselves and do not come into direct contact with metal components. Instead, they are crushed by impact and friction with the material lining layer. This reduces corner contamination and prolongs mechanical wear time. The ingenious self-circulation of airflow inside the vortex cavity eliminates dust pollution.
