Shaft Impact Crusher

There is two franges from verticals symmetry on both end of the shaft impact crusher,the high speed revolution roller is drived by the multiple groove pulley. Materials enter into the hopper,through the center feeder into the high speed impeller ,and speedup at more than ten times of the gravitational acceleration, then discharged from the discharging opening. Firstly, they bump with other materials which fall free after being bounced back. Then they impact together on the liner plates, and bounce back to the top area of vortex chamber.Again, the materials turn their moving direction , and this time move downward, thus to form a continual material layer by striking with the materials launched from the impeller channel. In this way, big materials are impacted, rubbed and crushed two and even more times inside the vortex chamber, finally discharging in smaller size at the bottom.

Applicability

Shaft impact crusher is widely used in medium and fine crushing of special materials with high hardness and ultra hardness, such as all kinds of mining stone, concrete, fireproof material, bauxite, emery, glass raw materials,ect. It is widely used in the field of hydropower, highway,construction, concrete and metal mining.The final product is in the shape of cubic, with low content of elongated flaky particle. It is more widely used in crushing machine-made construction sand, stones and all kinds of metallurgical slags. Compared with other crushing machines, it is characterized by higher capacity, stable operation, easy maintenance and high sand-making rate.
