VSI Vertical Shaft Impact Crusher

Usage and Application
VSI impact crusher is a classic type of fine crushing equipment, which fully embodies advanced fine crushing technology. It is mainly used for the production of high-quality sand and stone aggregate for the construction of highways, high-speed railways, hydropower projects, airports and other construction projects. It is an ideal equipment for sand making and stone shaping.

Features
1. Hydraulic cover opening device makes it easy to repair and maintain which saves time and effort.
2. Compared with traditional vertical shaft crusher, the reasonable structure design of crushing cavity can decrease the abrasion, reduce cost and increase the capacity.
3. Special feeding crushing structure can easily realize the free conversion of "stone strikes stone" and "stone strikes iron" crushing.
4. Vibration alarm device could detect automatically and ensure the reliable operation of equipment.
5. Thin oil station lubricates, double oil pumps supply oil complementary, ensure the bearing lubrication is always in good condition, this could extend service life of the equipment.
6. The finished product has excellent grain size, reasonable gradation and adjustable fineness modulus.

This machine has two kinds of feed mode, the central feeding: materials fall into the hopper and enter high speed rotating rotor via center feeding mouth. Inside the rotor, materials are rapidly accelerated and thrown out of rotor with high speed. First to impact with materials which are falling freely after rebound , then hit together on the lining or back block, be inclined upward rebound to the top of the crushing cavity, then deflected downward movement, and strike with materials emitted from impeller passage to form a continuous material curtain. Materials are impacted, rubbed and ground by many times in the vortex crushing cavity to be broken finally, crushed material is discharged from bottom discharging mouth. The central feed falls with the annular waterfall: the material falls into the hopper and falls down through the annular hole, being divided into two parts by the feed plate, one part enters the high-speed rotating impeller through feed plate, the other part falls down around the feed plate. Materials in impeller are cast in high speed, firstly impacted with part of the materials free falling, then hit together into the whirlpool materials liner around the crushing cavity, rebound by material lining, oblique shocks upward to the top of the crushing cavity, then deflected downward movement, strike with materials emitted from impeller passage to form a continuous material curtain. Materials are impacted, rubbed and ground by many times in the vortex crushing cavity to be broken finally, crushed material is discharged from bottom discharging mouth.
