VSI Sand Making Machine

Vertical shaft impact crusher is widely used in all kinds of mineral, cement, corhart, bauxite chmotte, carborundum grain, glass raw material, machine made construction sand, stone stock and all kinds of metallurgy slag, especially carborundum, sintered bauxite, magnesite, and so on material with features of very hard and anticorrosion. And Sand Making Machine is more productive than other kind of crushers.

Working Principle Of  VSI Sand Making Machine: 
Stone less than 60mm enters sand making machine though conveyor belt. Stone is crushed by hitting other stones. 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.

Characteristics of VSI Sand Making Machine: 
Simple structure and low operating cost;
High efficiency and low consumption;
Sand Making Machine has the function of fine crush and crude grinding;
Slightly influenced by the moisture content of material, and the max moisture content is 8%;
More suitable for crushing mid-hardness and high-hardness materials;
Cubic shape of final products, high density of piling up and low iron pollution;
More wearable and easy maintenance;
