Shear rates were estimated by considering the ball charge motion inside the mill. Two types of ball motion, cascading and cataracting, were taken into account. For the first type of motion, Morrell's power model approach [Morrell, S., 1996. Power draw of wet tumbling mills and its relationship to charge dynamics: Part 1.

the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application. The critical speed of a ball mill is calculated as 54.19 divided by the square root of the radius in feet. The rotational speed is defined as a percentage of the critical speed. Smaller diameter mills

Engineers use the shear rate between the screw and the barrel wall during this process. In contrast, the shear rate as the screw penetrates the steel disk is γ = (4 x Q) / (π x R 3 __) with the volumetric flow Q and hole radius R, which still bears resemblance to the original shear rate formula.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
