Tip Speed Calculator. Otherwise known as peripheral velocity, this calculator determines the velocity of the impact surface of a hammer at the outer edge of a rotor disk. Tip speed is important because the hammer velocity directly affects how much force is applied to particles being milled. Faster tip speeds general produce smaller particles ...

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

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.
