Read MoreA hammer mill drive must be equipped with a frequency converter in order to be able to control the speed and thus adjust the capacity and resulting fineness of the materials. 3.5 Product feed The feed to the mill must be controlled (at least roughly) by a dosing equipment such as a vibrating tube, a screw conveyor, or an airlock rotary valve .
Read MoreHammer Milling. Hammer Mills use mechanical 'in-air' impact forces to transform bulky raw materials into uniform particles. The key variables controlling particle size are rotor speed, screen size & geometry and feed throat. Fitzpatrick Hammer Mills produce the smaller PSDs and are more suited to abrasive and difficult to mill products.
