Vertical Shaft Impact Crusher (VSI Crusher) is a kind of crushing equipment to make artificial sand. According to the material and the final product the customer request, the impact crusher, cone crusher or vertical shaft impact crusher are available. But the Vertical shaft impact crusher is the most widely used in sand making field according to its industry function and usage scope. So it also named sand making machine. In fact, the sand making machine is not limit to vertical shaft impact crusher.
Sand making machine 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.
1.After perfection of rotators of the deep chamber, throughput of materials has increased by about 30%.
2.Direction of side plate can be adjusted upside down after it’s partially damaged, which will be able to bump up material using rate and prolong life span by more than 48%.
3.A combine design of hammbers can enable only damaged hammers being changed, which will enable using cost being reduced by more than 30%. Beside, assistant hammers are installed, which will be able to effectively protect side plate from being damaged while main hammers are damaged.
4.Key abrasion proof material is the high abrasion proof and high tempreture proof materials used in important industries of America.
5.A diamond impact block is adopted to protec plate from being damaged while materials are impacting.
Feed at center:
Materials fall into the hopper and then through the feeding opening in the center enter the high speed rotor which will throw out the materials with high speed. Materials firstly strike those materials that are free falling down.. Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing chamber and then fall down. After that, the falling materials with materials shot from the impeller form a continuous materials curtain. Ultimately, crushed materials will be charged from the discharging opening.
Feed both in the center and from sides:
The materials fall into the hopper and the circle hole and then will be divided into two parts by the distributing plate. One part of materials cross the distributing plate and enter the high speed impeller and then is accelerated and thrown out .The other part falls down from the sides of distributor. Materials firstly strike the free falling down materials.Then, materials strike the materials-liner in the vortex or the impact liner and are rebounded to the top of crushing cavity and then fall down. The falling materials with materials shot from the impeller form a continuous curtain of materials. At last, crushed materials will be discharged from the discharging opening.
