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.

PCL Sand Making Machine is suitable for crushing and shaping soft, medium-hard and very hard materials. It is widely used in all kinds of minerals, cement, refractory material, carborundum grain, glass raw material, construction sand, stone stock and all kinds of metallurgy slag, especially carborundum, sintered bauxite, magnesite, such materials are with features of very hard and anticorrosion. And Sand Making Machine is more productive than other kind of crushers.
In project, it is the ideal equipment for the production of artifical sand, cushion layer, asphalt concrete aggregate and cement concrete aggregate.
In the mining industry, it is widely used for the forepart of grinding because it can produce a mass of powdered ores. So the costly grinding process could be easier.

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 outlet downward, then go to vibrating screen which controls the size of final product.
