Cone crusher is a primary crusher, used in mining or Ore processing. It reduces large aggregates to smaller aggregate.
VSI means, 'Vertical Shaft Impactor'. In which shaft and crushing chamber are in a vertical position which is a latest crushing technology.
The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher.
The stone or material fed at the center of the rotor, which is rotating at high R.P.M. accelerate the material and material is thrown out from the rotor with a vigorous velocity of 300 ft. per sec. The main advantage of this process is material breaks at the minimum surface area, which makes the particle of cubical/spherical shape and brings consistency in size.
