Vertical Shaft Impact Crusher By Henan Liwei Industry Co., Ltd.

VSI Series Vertical Shaft Impact Crusher has another name called Sand Making machine. Sand Making machine is high-performance equipment for sand making and shaping, is researched and produced by our corporation through absorbing the advanced technology from Germany, and has achieved world advanced standards. This equipment has two types: rock-on-rock and rock-on-iron. Sand yield of ock-on-iron?type is higher by 10-20% than that of ock-on-rock? type.

Usage:-
1.It is used for producing building aggregate, concrete, aggregate for road surface and roadbed, asphalt concrete and cement concrete.
2. It is also used for sand making and shaping in the field of engineering such as water conservancy, hydroelectric power, high-class highway, railway, bridge and municipal works.
3.It is used in fine crushing of mining industry such as building materials, metallurgy, chemical engineer, mining, anti-fire material, cement etc.
4.Sand Making machine is used for producing glass raw material and quartz sand etc.

Working Principle:-
Material falls down onto impeller cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impeller and shell, and hit each other several times; finally smaller stone comes out, and goes to vibrating screen. Satisfactory material is transported by conveyor belt. However overlarge material will go back to sand maker to be crushed again.
