Hammer mills are of two types, Horizontal shaft (Moves horizontally)and verticle shaft (Moves Vertically) types. They differ only by moving conditions, although the remaining things ...
The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.

Among those styles, the functionality of a hammer mill remains basically the same: Material is fed into a grinding chamber. Contact with moving hammers, and interior mill components reduce the material's size. Material remains in the hammer mill's grinding chamber until it is able to pass through a screen or grate with certain size openings.

There are screenless hammer mills, which use air to separate large and smallsized particles. These hammer mills serve as primary, secondary, or tertiary material crushers. The size and power capacity of hammer mills vary according to the application. The industrial hammer mills use the electric motors of power over 2000 to 5000 horsepower.
This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.
