Hammer Mills

The robust, industrial hammer mills type HM 142, HM 342 and HM 672 are used for crushing materials ranging from dry to damp, soft to tough, chewy to brittle. Depending on product characteristics and the desired milling result, both types may be equipped with a variety of sieve and bar grate screen inserts. Comfortable acces to hammers, shaft and sieve insert for revision and maintenance is provided by the foldaway fronthousing. The sieve insert in easily changed from the side. The JEHMLICH hammer mills are designed for both standalone operation (batch) and direct integration into a production line.

Both types are available in mild and stainless steel.

• Crushing as preparation for fine milling

• Crushing of soft to hard, tough or damp materials

• Sample preparation for research institutions
