A hammer mill is a mill whose purpose is to shred or crush aggregate material into smaller pieces by the repeated blows of small hammers. These machines have numerous industrial applications, including: Ethanol plants (grains) A farm machine, which mills grain into coarse flour to be fed to livestock Fluff pulp defiberizing Fruit juice production

A roller mill produces far less heat and dust compared to a hammer mill. The grooves of a roller cylinder can be switched out to suit your needs depending on the material. Hammer mills don't have this kind of customization. Milling Capacity. One of the best benefits of hammer mills is the amount of material they're able to process at one time.

Hammer configuration and thickness: more hammers means finer grinding, but also higher energy requirements. Thin flat hammers (3 mm.) generally affect milling positively in terms of output and thicker hammers tend to push the product forward, instead of reducing it. The degree of wear should be checked regularly: excessively worn hammers reduce ...
