### Cement Kilns: Size Reduction and Grinding

In 1904, Krupp produced a self-contained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.Effect of ball and feed particle size distribution on the,Jun 01, 2018· In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

### Particle Size Distribution of Grinding Mill Products

Apr 27, 2019· A comparison of the size reduction by impact and ball mill grinding is shown in figure 2.
