The Hamex® Full Automatic hammer mill runs at a lower speed than the Hamex® hammer mill, namely a maximum of 1800 rpm. However, the tip speed of the hammers has remained the same, so you can achieve a comparable grinding with lower energy consumption. Thanks to the robust design and the relatively low speed, there is also a minimal noise level.

A hammer mill is an essential machine in the pharmaceutical and food processing industries. It can be used to crush, pulverize, shred, grind and reduce material to suitable sizes. In a hammer mill, swinging hammerheads are attached to a rotor that rotates at high speed inside a hard casing. Principle of Hammer Mill:

The hammer mill works with a sieve to control the particle size inside the system which can ensure that no oversized ends up in the product fraction and significantly lowers any yield loss. Screens, set at a specified cut point, retain coarse particles for further grinding while allowing product sizes below the cut point to pass and exit the mill.
