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.
The larger hammer circle on certain Meteor Hammer Mill models allow a lower RPM operating speed, producing high quality fiberized material while reducing operating noise, bearing down time, and vibration. A Williams Meteor Hammer Mill is constructed of heavy 1/2" plate for both the housing and rotor.
Because tip speed is a function of hammermill diameter and motor speed, it is necessary to have a variable frequency drive on the hammermill motor to adjust tip speed. The variable frequency drive allows the operator to adjust hammer tip speed while requiring minimum idle time. Related: Grain particle size analysis recommendations updated by K ...
Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill's chamber through the feed chute, typically by gravity, where it is struck by ganged hammers attached to a shaft that rotates at high speed inside the mill's grinding chamber.
