Hammer & Screen Milling

Mikro Pulverizer® Hammer & Screen Mill is is a high speed mechanical impact mill designed for continuous size reduction of a wide range of materials down to D90 = 45 microns. This device was originally invented by Hosokawa Micron Powder Systems in 1923 and has evolved into the preeminent industrial mill with thousands of worldwide installations.

These systems are suitable for grinding soft to medium-hard materials with a Mohs hardness of less than 4. Designed with flexible controls and numerous configurations, this device can be used for coarse granulation or as a fine size reduction machine.  

The principle of operation of these hammer and screen mills consists of a high speed rotor assembly fitted with sets of hammers. The grinding chamber is fitted with a cover containing a multiple deflector liner and a retaining screen at the bottom of the grinding zone. The grinding process is controlled by the type of hammers, the rotor speed, the type of retaining screen and the liner.
