Introduction. The Haarslev Wet Mill is designed for crushing and grinding large volumes of wet poultry or red meat. This type of hammer mill equipment is usually part of a complete Haarslev fluidizer system, used for sizing coarse "wet" inputs into a meat slurry consisting of small particles that can be cooked quickly, with only a short retention time.

Increasing hammer tip speed increased (linear, P < ) AoR. Increasing screen hole diameter decreased (linear, P < ) AoR. In summary, the particle size range for a specified hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible using motor variable frequency drives.

A] Hammer Mill Working Principle and Main Components. The process of size reduction (for feed material) is carried out by rectangular pieces of hardened steel that rotate inside the chamber at a high speed, striking the material to be milled with a powerful force. These radially swinging hammers (from the turning central shaft) help crush/grind ...

Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
