9FQ type feed hammer mill crusher working principle
feed Hammer mill work on the principle that most materials will crush or pulverize upon impact using the following steps:
Firstly, materials is fed into the feed grinding mill chamber typically by gravity.
The second, the material is struck by ganged hammers (rectangular pieces of hardened steel) which are attached to a shaft which rotates at high speed inside the chamber. The material is crushed or shattered by the repeated hammer impacts, collisions with the walls of the grinding chamber, as well as particle on particle impacts.
The third, perforated metal screens, or bar grates covering the discharge opening of the mill retains coarse materials for further grinding while allowing the properly sized materials to pass as finished product.
