It is also similar to a ball mill because it uses balls, usually ceramic ones having 5-15 mm in diameter. Because the motion of the balls is independent of gravity, an attritor can handle thixotropic materials and slightly higher viscosity of millbases, but the principle of action and type of forces operating are similar to those of the ball mill.

The rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods. This means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct.
diameter Ball Mill 28 RPM. For most grinding and dispersing problems, we strive to attain the cascading, sliding action described earlier, and to accomplish this we have found that the most desirable angle of break ranges from 50° to 60° from the horizontal. The lower range is recommended for most wet grinding operations like paints and soft dry
of grinding action takes place at the surface and diminishes the closer you get to the jar wall. Optimized Rotation Speed: The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to

Tumbling ball mills are a common comminution device in the mineral industry processing, wherein the particle size reduction is performed by action of the grinding media. Different forms of transverse motion in a rotating cylinder have been studied by many researchers. The aim of this paper was to study the transitional phenomena between cascading, cataracting and …

Ball Mill. Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.
A ball mill is partly filled with steel balls (some are cylindrical shaped cylpebs) that impart a tumbling and cascading action when the mill rotates around its horizontal axis. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel or manganese steel.

Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve …
The rotating velocity of the mill in cascading or cataracting is determined and import to software. The different states of media motion can be analyzed by PFC model as shown in Fig.5.

The mill is kept about half-full of balls and is driven at the speed at which their cascading and rolling action has the maximum crushing and grinding effect on the ore as it passes through under pressure of incoming feed ; the cascading action crushes the ore by impact and the rolling action grinds it by attrition.
