Grinding Mills. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016 7.1 Introduction. Grinding is the last stage in the comminution process where particles are reduced in size by a combination of impact and abrasion, either dry, or more commonly, in suspension in water.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

A 1-5/8" hole is drilled into the bottom of the blank for the grinding hardware retention plate. Next I switch to a 1-1/16" forstner bit and drill from the top and then the bottom of the pepper mill body. Once I've gone as far as possible with the forstner bit, I'll switch out to a 1" speedbor to hog out the rest.
