The basic principle is straightforward. A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft which hammers are mounted. The hammers are free to swing on the ends of the cross, or fixed to the central rotor. The rotor is spun at a high speed inside the drum while material is fed into a feed hopper. The material is impacted by the hammer bars and is thereby shredded and expelled through screens in the drum of a selected size.

LZ series sand recycling machine manages to resolve this flaw which stated before. Now this products are now distributed in the most of developing countries and widely used in glass raw material processing system, artificial sand production line, slime recovery project and environmental engineering.
