Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case It produces size reduction by impact The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer) which rotates at high speed inside the chamber
Hammer Mill Operating Principle We have never subscribed to the idea that the hammermill is suited to the primary breaking of shovel-loaded, quarry-run, or ROM mine-run rock and ore Even though the material be non-abrasive and quite friable there are other machines which are better fitted for such work

25 Operating Principles Figure 2-1 illustrates the basic operating principle of the Prater Full Screen Hammer Mill The G Series mill uses a shaped grinding chamber with distinct grind and release zones Coarse material is fed to the mill through the top product inlet usually by a gravity rotary feeder
The basic principle is straightforward A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted The hammers are free to swing on the ends of the cross, or fixed to the central rotor The rotor is spun at a high speed inside the drum while material is fed into a feed hopper
Pin mill work by similar principle as hammer mills (impacts and shearing) but with typically faster tip speed rotor-stator configuration of intermeshing pins which impact the particles as solids are directed through the intermesh pins The mill product leaves by centrifugal forces to the periphery and is then collected or further processed
