gear technology, the standard drive design of Vertical Roller Mills (VRMs) comprised gear units featuring a bevel stage and two helical gear stages. When RENK presented the first planetary gear unit for VRMs in 1979, its compact dimensions and the lower gear unit weight were a true innovation. The new concept made it possible to design
The mill design was then made with consideration for the estimated hardness of each block in terms of both SAG and Ball milling with allowance for annual periods when the ore is harder to grind. Operating specifications were selected to achieve an optimum of capital and operating costs through use of the CEET program.

The American Gear Manufacturers Association (AGMA) Mill Gearing committee recently released AGMA 6014, a standard for rating gears for grinding mill and kiln service.
Cup-shaped grinding wheels are dimensioned to duplicate the cutting channel for one particular gear design (with stock allow-ance taken into account). A typical cutting or grinding channel is shown (Fig.2). Particularly for large spiral bevel gear sets, it is common to use pressure angles of 20° for concave and convex flanks. In such
