Sand making machine(sand maker) also named vertical shaft lmpact crusher is a kind of advanced equipment with high-efficiency and low-consumption, which is designed basing on our chief engineer Bai Yinghui many years hard work and study of mechanical equipments. It absorbed the advanced technology of the similar products of Barmac Company of America, now it is of the international advanced level. It plays an irreplaceable role in crushing minerals into pieces.

Usage of Sand Making Machine:
The vertical shaft lmpact crusher is widely used in many kinds of minerals, cement, refractory material, bauxite chamotte, carborundum grain, glass raw material, artificial construction sand, stone and all kinds of metallurgy slag, especially carborundum, sintered bauxite, magnesite, etc with features of high hardness and anticorrosion. This series of crushers are more productive than other kinds of crushers.

Working principles of Sand Maker:
Materials fall from the upper part of machine to impeller which rotates at a high speed. Under great centrifugal force, they hit materials scattered around the impeller. After hitting each other at a high speed, there forms a vortex between impellor and shell, and materials hit each other several times, finally smaller pieces come out through downside outlet, and then go to vibrating screen which controls the size of final product.

Characteristics of Sand Making Machine:
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 high-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.
