CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

The flat die pellet mill was designed around the turn of the 20th century to produce animal feed. The ring die pellet mill design was not really developed until the 1950's. The original purpose for all pellet mills was to compress animal feed into pellet form. There were several advantages of processing animal feed into pellets.
