VSI Sand Making Machine

VSI sand making machine is the first stone crusher designed by our company which crush between materials and crush between materials and liners. It has two kinds of crushing chamber, “rock-on-rock” and “rock-on-anvil”. “rock-on-rock” is suitable for hard materials. The sand making ratio is above 40%. “rock-on-anvil” is suitable for medium-hard materials. The sand making ratio is above 50%. These two kinds of crushing methods can transform to each other so as to suit different materials. It is widely used for metal and non-metal ores, highways, Water conservation and hydropower, refractory material, abrasive material, ceramic and glass material, aggregate for building, sintered bauxite, magnesite. It has many advantages than other kinds of stone crushers.

Characteristics

Lubrication system ensures reliable operation; The adjustable feed hopper guarantees the best quantity of material; cubic shape of final materials; high output and low power.

Working Principle

Rock-on-rock: material fall down from the top equably. Some enter into the high-speed impeller through distributor and pipes, and then are thrown out from the outlet of the impeller by the high-speed centrifugal force. Material which are thown down by impellor hit the material around impeller which are parted like an umbrella by distributor. And then, the material formed vortex in the impellor and vortex chamber and are crushed after hit and frication for many times.

Rock-on-anvil: material fall down from the top equably, enter into the high-speed impeller through pipes and are thrown out from the outlet of the impeller. At last the material are crushed by hitting the adjustable impact plate or impact bar opposite impeller in the vortex chamber.
