For small throughput
Our universal and small hammer mill
The hammer mill HM is a universal and small machine for grinding a wide range of products, such as grain, mixed feed, cleaning waste, fish meal, etc.
It is designed for pneumatic conveying of the ground product. A specially designed rotor, similar to a blower, generates a strong air flow for product transport through the mill into a separator. The HM series includes two housing sizes for motorization from 11 kW to 45 kW drive power.
Small and universal
