Mill Speed

13.1.1.2 Medium-speed mill. Medium-speed mills are smaller than low-speed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.

Rod mills deliver a more uniform granular product than other revolving mills while minimizing the percentage of fines, which are sometimes detrimental. The pebble mill is a tube mill with flint or ceramic pebbles as the grinding medium and may be lined with ceramic or other nonmetallic liners. The rock-pebble mill is an autogenous mill in which the

Turning a Crushgrind Mill

Assembling the Crush Grind Mill. Mount the crush grind mechanism into the mill body and mark the shaft where it sticks out 1-1/8" from the body. Cut the shaft at this mark and file the end to a taper. This removes any sharp burrs and makes the head easier to install. Now we'll use epoxy to glue the mechanism in place.
