VSI Sand Making Machine
Capacity: 30-900 t/h
Discharge Fineness: ≤5 mm
The VSI sand machine is a high-performance fifth-generation sand making equipment developed by Liming Heavy Industry. Based on the combined principles of "stone-on-stone" and "stone-on-iron" crushing, it is specially designed for the production of high-quality manufactured sand. Integrating the functions of crushing, shaping, and sand making, this equipment offers unique technical advantages: optimal particle size, uniform particle size distribution, and precise control of fines content, making it an essential component of modern aggregate production lines.
Mineral Processing:

Working Principle
Feeding: The material is divided into two streams by the distributor.
Acceleration: One portion is propelled at high speed by the rotor.
Curtain formation: The other portion creates a curtain of material.
Primary crushing:
Stone-on-stone impact between the projected material and the curtain.
Stone-on-iron impact against the protective plates.
Classification: The treated particles are discharged through the screen.
This advanced technology enables the efficient production of premium-quality sand, while ensuring sustainability and environmental friendliness.
