A hammer mill has a horizontal rotor with a shaft that contains hammers, also called blades or knives. These are the elements that crush or grind the bulk material, that rotates with a speed that is settled according to the material that is being processed. This machine also contains a screen that filters the crushed material and ensures that only the particles with the desired size pass through.

The hammer mill needs to have sensors of speed and temperature to keep in good conditions the machine as well as the raw material, moreover to control the variables of the process. Choose a hammer mill with easy access to the chamber to do maintenance and reparations, furthermore replace the hammers frequently to guarantee their sharpness and good state.

This mill equipment is an important part of the process line of feed, food, chemicals, and cosmetics.

A roller mill has one or more cylindrical rollers or wheels, that rotate to crush or grind the materials by friction.  They can be horizontal or vertically oriented. The horizontal roller mills have rollers placed parallel in the horizontal axe, turning in opposite directions and at different speeds, generating pressure and tear between them and the material that passes through. The vertical roller mills have a spinning plate or grinding table with rollers placed in its perimeter, which exerts vertical pressure on the material over the plate.

The roller milling equipment is great to grind grains, cement, clay, rocks, and other minerals. Due to the tear and wear of the rollers, it is important to have regular maintenance and replacement of the rollers, especially if they process abrasive materials. Is also important to adjust the gap between the rollers according to the material and particle size you need.
