DHM Dry Grinding systems
For dry grinding of industrial minerals

DHM dry grinding Mill is an impact grinding system with integrated classifier and therefore ideal for products with steep particle size distributions. The multipurpose mill can be used for soft and medium hard minerals where wear resistant materials can be chosen.This innovative air DHM Grinding mill is capable of fine grinding all kinds of dry products with virtually no contamination.Through this specialized milling concept, product grinding is entirely autogenous. ball alone create the grinding energy. No tool wear occurs!
DHM systems have been designed for dry milling hard materials, They are used for the continuous production of micronised powder. The production cycle is fully automated to offer a high production output and low energy consumption.
An integrated dynamic classifier in the housing can be infinitely adjusted to the desired fineness. This guarantees exact adjustment of the grinding parameters and reproducible product quality.

Even the hardest of products poses no problem for this machine. In addition, extremely temperature sensitive products such as wax can be processed under continuous operation.

The horizontal mill drum rotates with  x but optimum speed and moves/transmits the grinding energy to the balls. The comminution takes place between the grinding media by compression, friction and impact. The air ow allows a continuous process and a uni- form product  ow through the drum. Product and air leave the mill drum and enter the external dynamic air classi er. The product  neness can be adjusted fast and easily by changing the classi er wheel speed.
