Effects of grinding aids on model parameters of a cement

The impacts of the grinding aids on the ball mill are mathematically expressed using the obtained data from industrial tests. The particles at a certain size in the mill are formed by both particles at that size present in feed and the particles that are broken from coarser size to that size.

Effect of Slurry Solids Concentration and Ball Loading on

The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the results.
