The material enters into crusher through material entered bucket, the material is divided into two parts thought material distribution device, parts of the material enter into high speed rotated impeller through the middle of the material distribution device and are fast accelerated inside the impeller, their speed can reach one hundred times acceleration of gravity, and then are cast out through around flow ways of the impeller by 60-70m/s, firstly are impulses and crushed with partial materials freely fallen from around material distribution device and then they are impulsed into vortex lining layer in vortex crushing cavity and rebounded by material lining layer and up to the top of the vortex crushing cavity and then changed their moving direction and are turned down towards and formed material continuous screen with materials emitted form impeller’s flow ways .so, a piece of material has twice to many times probability to be impulsed ,rubbed crushed and milled in the vortex crushing cavity, the broken materials are discharged through discharge outlet at the bottom and formed into closed route through circulating sieve system, generally three times circulation can crush the materials under 4.75mm,the clever air self circulation in the vortex cavity eliminates dust pollution
