The simplest way to describe the concept of size reduction is to look at the industrial hammer mill model: Hammer mills operate on the basic principle that most materials will crush, shatter or pulverize upon impact. This is accomplished by a simple four step process: Material is fed into the mill, typically by gravity.

Hammer Design The design and placement of hammers is determined by operating parameters such as rotor speed, motor ... Optimal hammer design and placement will provide maximum contact with the feed ingredient. Mills in which the rotor speed is approximately 1,800 rpm, hammers should be about 10 inches (≈ 25 cm) long, inches (≈ cm ...
Hammer Mill From dry saw dust to powder Up to 32 t/h High capacity Low energy consumption Direct or indirect coupling Bidirectional rotor The robust design of PromillStolz hammer mills allows to reach high level of quality and output, for a large range of applications. Parts and materials are chosen to fulfill specific needs, in order to optimize their lifetime (hammers, screens, body.).
Pneumatic Discharge Hammer Mills The grinding mechanism of this group is quite similar to the gravity discharge hammer mills. However, the pneumatic mills typically use a thinner hammer and the interior wall of the grinding chamber features a ribbed liner plate. This plate has a washboard effect on the material, and works in unison
