The HAMMER MILL MACHINE is the most common and oldest form of grinding mill. Hammer mills are made up of a series of hammers that are connected by a central shaft and housed in a rigid metal frame. It reduces the size of the object by impact. These rectangular pieces of hardened steel, which rotate at a great speed within the chamber, strike the materials to be milled. All in all, by using the HAMMER MILL MACHINE, the feed material is brittlely fractured by these dramatically swinging hammers, which travel at a high angular velocity.
