Deep Rotor VSI Crusher introduces German technology. DR VSI crusher with many patents is key equipment in sand making area. DR VSI crusher is a kind of totally new high efficient crusher.
DR VSI crusher is widely used in various metallic and nonmetallic ores, cement, corhart, abrasive material, glass, construction material, machine-made sand, metallurgy, etc. It is also applicable to crush various stones with different hardness in medium and fine crushing area, such as iron ore, non ferrous metal, emery, bauxite, quartz sand, basalt, etc.

Advantages:
It has the following features:
1. Rotor with deep chamber increases 30% capacity after perfect design.
2. Side plate direction can be changed to increase material utility ratio, operating ratio can be increased 48%.
3. Worn hammer with combined type is only changed to reduce operating cost 30%. Another pair of vice hammer is added to prevent from damaging main hammer and side plate.
4. The most key wear resistant material uses wear resistant and high temperature resistant material in American important area.
5. Rhombus shape impact plate is used to prevent side plate from being damaged.
6. Bearing is famous international brand imported from Japan, Sweden, America, etc.
7. Perfect discharge and smooth curve reduce resisting force when material flows, so capacity is increased greatly.
8. Spread dish with double purposes can make two feeding ways change easily.
9. Special seal structure under main shaft guarantee no oil leak without seal.
10. Japanese hydraulic opening cover device is originally imported. The cover is moved easily and inspection of inner part is easy.
11. Motor with high grade of protection is selected. The motor has features of high efficiency, low noise, etc. The motor complies with IEC, insulation grade F, protection grade IP54/55.

DR VSI crusher mainly consists of: (read drawing one) riveting basic part, main shaft assembly, rotor assembly, driving motor, frame assembly (including upper and lower frame), hydraulic jacking and turning device, platform on each side.  Assistant part is made up of electrical system and lubricating system.
