Product Introduction

The impact sand making machine is designed for crushing and shaping brittle materials with Mohs hardness ≤9. It integrates efficient crushing, particle shaping, and uniform classification functions.

Key Applications:

Metal/non-metallic ore processing
Construction aggregate production (artificial sand, gravel)
Metallurgical slag recycling
Building materials crushing

Advantages & Characteristics

Working Principle

Materials enter the feed hopper and fall through the annular opening, where they are split into two streams by the distributor plate:

One stream passes through the central hole and enters the high-speed rotating impeller;
The other stream falls around the periphery of the distributor plate.

The material entering the impeller is rapidly accelerated (reaching an acceleration of dozens of times the gravitational acceleration) inside the impeller, then ejected at high speed. This ejected material collides with the second stream (falling around the distributor) for initial crushing. Both streams then impact the vortex lining in the vortex chamber, rebound off the material lining, and strike the top of the vortex chamber at an upward angle. Their direction of motion shifts downward, and they collide with the material emitted from the impeller’s flow channel—forming a continuous material curtain.

A single material particle undergoes multiple impacts, friction, and grinding within the vortex crushing chamber until it is reduced to the desired size. The crushed material is finally discharged through the bottom outlet.
