The hammer mill is machinery which is mainly used to crush the materials dimension between 6mm and 50mm such as tree branches, cotton stalk, corn stover, corn cops and other agro-wastes. So it is also called wood crusher, Through processed by hammer mill, the size of raw material can reach less than 3-5mm, then the materials can be further processed by other pellet mill equipments.

The work principle of hammer mill is very simple. In fact, the wood hammer mill is a steel drum that consists of a vertical or horizontal rotating shaft or drum. The rotor is spun at a high speed while the raw materials are fed into the feed hopper. Under the impact of hammer bars, the raw materials is shredded and expelled through screens with a selected size.

However hammer mills have wide applications in different lines. Choosing a right equipment is not an easy job to fit the wood pellet plant. KMEC, a specialized manufacturer, will provide professional hammer mill for the pellet production line through technical innovation. For example, wood chips, tree branches and agro straws can be crushed into small sizes to meet standard size.
