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.

Advantage

1. Superior sand quality
Rounded particles with less than 5% flat/elongated particles
Continuous particle size distribution and adjustable fineness modulus
2. Energy-efficient design
30% improved crushing efficiency compared to conventional equipment
20-25% reduction in energy consumption
3. Exceptional wear resistance
Critical components made of high-chromium composites
Reversible protection plates extend service life by 50%
4. Intelligent control
PLC control system with one-click start/stop
Real-time monitoring of operational parameters
5. Environmental performance
Completely enclosed structure limits dust emissions
Noise level below 75 dB
6. Simplified maintenance
Hydraulic opening for easy access
Interchangeable modules for main components

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.
