This heavy duty Industrial Rotopactor is used for production of sand from grit. This crushing system is equipped with rotatable disc that applies heavy force for throwing stones that collide with its annular rings. As its result, those thrown stones break into small particles and tend to rebound in upward direction. As its consequence, those stone particles falls on ground and break into fine particles. These particles are again thrown from the rotor of this machine so that these can collide with the screen to transform into finer particles. Provided Industrial Rotopactor is well known for its high production capacity, low noise and vibration generation level, ergonomic appearance and standard dimension.
