Vertical Shaft Impact Crusher have another name called Sand Maker, which is  of high energy but low consumption and of international advanced level developed by introducing foreign outstanding technology of the same type of products. At present, it is the most advanced and practical equipment for medium-sized and fine crushing and shaping. It plays an irreplaceable role in fine crushing and sand making .

Vertical Shaft Impact Crusher  is widely used in fine crushing and rough grinding of metal, mineral, building aggregate, concrete, anti-fire material, glass raw material, manufactured sand and all kinds of metallurgical slug. It is also can utilized in shaping of high rank road surface.

Features

1.    Simple and reasonable structure,low operating cost

2.    High strength wearable parts,the use of cost savings

3.    Advanced principles and technology,energy efficient,large crushing ratio

4.    Simple maintenance convenience,saving time

5.    Solve the universal problem of motor frame being easy to break

6.    Reduce the chance of damage to the machine

Operating principle

Stone enters sand making machine through the belt conveyor.  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 to sand washing machine, however overlarge material will go back to sand maker to be recrushed. Output sizes can be made according to customers requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
