It is possible to make an approximate calculation of the capacity of a ball mill by means of the equation: N = ( D 3 L ρ b .ap ϕ 0 .88 + L n ) 1 η 1 η 2 where ρ is the apparent density of the balls; l is the degree of filling of the mill by balls; n is revolutions per minute; η .
Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 2 O).
The rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods. This means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct.

Ball End Mills. A ball end milling cutter is also known as a "ball nose mill". The end of this tool is ground with a full radius equal to half of the tool diameter, and the edges are center cutting. They can be single end or double end and they can be made from solid carbide or various compositions of high speed steel.
The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...
