Shot blasting is a method that basically consists of throwing an abrasive (abrasive grit) at high speed against the surface to be cleaned. The action of throwing the shot is achieved by centrifugal force, through the rotation of a turbine rotating at a continuous shaft speed. The blast media bounces off the surface to be treated and returns to the hopper for further processing.
Shot blasting machines are designed in such a way that the turbine throws the abrasive at an inclined angle to the floor surface to be cleaned.
