Function

Vertical shaft impact sand maker is a common machine for 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 .

Operating Principle

Material falls down to impeller cavity of vertical shaft impact used sand maker. Under great centrifugal force, it hits material that is flowing around the impeller as an umbel. After hitting each other, they force a vortex between impeller and shell and hit each other for several times, and finally smaller stone comes out and forms closed cycle. The required end product shape is controlled by the screen equipment.

Features
1. Simple structure and low operating cost;
2. High crushing ratio with low consumption;
3. Function of fine crushing and crude grinding;
4. Slightly influenced by moisture content of material, and the max moisture content is about 8%;
5. More suitable for crushing mid-hardness and hardness materials;
6. Cubic shape of final products, high density of piling up and low iron pollution;
7. More wearable and easier maintenance;
8. Low working noise (lower than 75 decibel) and light dust pollution.
