Hammer Mills, type PHM

Pulverizing of all types of brittle and fiberous,  medium hard to soft materials such as annual plants, roots, chemicals, pharmaceuticals, soft minerals etc.

Method of Operation

Installation of the hammermill is on the production floor or in a pit. Feeding is done manually. An infeed chute for belt conveyor feeding is available. Material is size reduced by impact with fast rotating, free swinging type hammers. A screen holds material inside the grinding chamber, as long as it is too coarse. Fine material gets discharged through the screen into a pneumatic discharge system. Bottom discharge onto a mechanical conveyor or into a bin is available.

An open rotor with hammers having a thickness of 8 mm is standard. Bearings are outboard and no grease can enter the grinding chamber. Hammers come in sets of equal weight.

The screen has a maximum open area for maximum capacity. The standard hole size of the screen is 10 mm ( 3/8"). Other screen sizes are available.
