Different Milling Machine Operations. A milling machine is a machine tool that cuts metal as the workpiece is fed against a rotating multipoint cutter. The milling cutter rotates at a very high speed because of the multiple cutting edges, it cuts the metal at a very fast rate. This machine can also hold single or multiple cutters at the same time.

Attrition mills mechanically reduce solid particles through the intense acceleration of particles against one another in a curved or flat grooved surface called a stator. These mills use a high-speed rotor to create centrifugal forces that facilitate the necessary particle interactions. Rotors' designs can vary, where some include m…

CONTINUOUS ATTRITOR ("C" OR "H" MACHINES) (Fig.5) C-machines are best suited for the continuous production of large quantities of material. H-machines are built the same as C-machines, but use smaller media (2-3mm) and run 60-70% higher rpm. A well-premixed slurry is needed to be able to use this type of process.

In the rod mill balls are replaced with rods equal in length to the drum. Attrition occurs in addition to impaction. Rod mills overcome the problem of ball mills clogging with sticky material. 15.2 Operating methods Batch operation is limited to devices such as the ball mill; most other milling equipment is used
