Hammer Mill HM

The hammer mill, also known as the pulverizer, works according to the principle of impact grinding. Its core consists of a rotor with wear resistant impact hammers and external housing for the roller bearing. Our hammer mill HM is ideal for grinding, crushing, and processing soft to medium-hard grinding materials such as minerals for preparation for further processing.

Suitable for Continuous Operation

A rotary airlock feeds the raw material to the hammer mill. During the crushing and grinding process, a controller adjusts the air lock speed and the mass flow of the entering raw material. The material is ground between the rotating beaters and the housing.

A fan generates a constant flow of air or hot gas and transports the ground product out of the mill housing into an air separator. There, a dust separator removes the finished product from the air flow.

Uniquely Designed for Low Maintenance

In general, it is possible to automatically and continuously discharge product components that are difficult to grind. However, this process is only possible with our HM hammer mill. This makes the hammer mill uniquely maintenance-friendly and achieves extremely long service lives even when handling difficult processes.
