1. Application of VSI sand making crusher machine:
Sand Making Machine (namely PCL Vertical shaft impact crusher) is of high-efficiency and low-consumption, which is designed depending on several years of hard work and study on mechanical mining equipment. Sand Making Machine absorbed the advanced technology of the same products of Barmac Company of America, now is of the international level. PCL 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 kinds of crushers.
2. Working Principle of VSI sand making crusher machine:
1. Center Feeding:
Raw material falls down into feed hopper, then enters impellor through central entrance hole. It is accelerated in high-speed impellor, then is thrown out at speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards though outlet.
2. Ring Feeding:
Raw material falls down into feed hopper, then through ring, it is devided into two parts by material-dividing plate. One enters into impellor through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impellor at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.
3. Characteristics of VSI sand making crusher machine:
1) High efficiency and low consumption;
2) Simple structure and low operating cost;
3) Sand Making Machine has the function of fine crushing and crude grinding;
4) More suitable for crushing mid-hardness and high-hardness materials;
5) Cubic shape of final products, high density of piling up and low iron pollution;
6) More wearable and easy maintenance;
7) Low working noise and light dust pollution;
8) Slightly influenced by the moisture content of material, and the max moisture content is 8%;
