MATERIAL RETENTION TIME IN A BALL MILL & VRM

 · The circulating load could be obtained by measuring the particle size distribution of the feed, the product and the reject, and by then using the Koulen method. (see this post ) The material M accumulated within the mill could be observed by measuring the level of the material within the mill, deducting the volume occupied by the balls and assuming a reasonable value for the material density.

THE OPTIMAL BALL DIAMETER IN A MILL

For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding.
