The PHR high-efficiency pulverizer is a shredder that combines attrition, impact and shearing actions. It can be fitted with different rotors to accentuate the effects of attrition or impact. The design incorporates easy access for maintenance and replacement of wearing parts. Mechanical parts are located outside the grinding chamber to protect them from damage caused by high-temperature drying.

Different materials are available for wear parts, as well as ceramic materials for abrasive products, which must avoid contamination by metal particles.
The PHR handles grinding/drying operations for product feed up to 85% moisture content. Combined with a dynamic classifier, it enables very fine particle sizes to be obtained.
