Indeed, according to Boulvin et al. [44], experimental data from a grinding circuit show that mill throughput impacts the separating curve. A recent experimental study on parameters affecting the VRM performance shows a correlation between product fineness and dynamic separator speed, mill throughput, and the rollers hydraulic pressure applied to the grinding table of the VRM [45].

Main Features of a Modern Wire Rod Mill. The objective of a wire rod mill (WRM) is to reheat and roll steel billets into wire rods. Wire rods are normally rolled in a highspeed rolling mill, where steel temperature is above 1,000 deg C, maximum speed of rolling can go up to 140 metres per second (m/s) and coils of wire rod produced can be up ...

Let us apply these ideas to the derivation of an equation for the rate of grinding in a mill. It follows that if, as appears reasonable, the change of specific surface S cm²/cm³, within a mill depends upon the diameter of the mill, upon the ball diameter and upon the mean diameter of the particle, D, d and b respectively, upon the density of the balls and the pulp, q and σ respectively, on ...
