Vertical Shaft Impact Crusher

The Vertical Shaft Impact Crusher is also called Sand Maker .Star Trace develop this domestic,international ,advanced level efficient crushing equipment combining the actual situation in domestic sand making ,and it is based on the “stone hit stone ”principle and technology .It is widely used in all kinds of hard and brittle materials for medium ,fine crushing .Such as ,rocks ,abrasive ,refractory,cement clinker ,quartz,iron ore and concrete aggregate and so on . And building sand ,building road gravel are the most appropriate.

Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times, finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported by conveyor belt. However overlarge material will go back to Vertical Shaft Impact Crusher to be recrushed. Output sizes can be made according to customer’s requirement.
