As a rst glance to the problem we compute the lling heights of the mill with only balls (dry milling), and balls with suspension for two di erent cases: 300 l and 400 l of suspension and a packing of the balls of 75% (25% free space between the balls). These lling heights are plotted in Figure 1.5 where h1 is the lling height with only balls and

The suspensions were prepared with a ball mill in 33% by particle weight using a dispersing agent. A qualitative interpretation was made for the development of the phenomenon with a floc model in which suspensions of acicular particles form bulky structures with larger volume fraction of flocs phase at higher rate of shear, …

Ball mills are a type of grinder used to grind and blend materials for use in various industries. The basic principle of ball mills involves two or more grinding media, such as balls or rods, rotating in a container to grind materials to a desired fineness. The principle of ball mills is based on impact and attrition.
