Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.

This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

For a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material. Ball Mills vs ...

11. Ball Mill: In case of continuously operated ball mill, the ceramic balls are fed up to 1/3rd portion of its volume. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell. In doing so, the solid particles in between the balls are ground and reduced in size by impact.

Supermill Plus SMP. Supermill EHP. To achieve optimal wet grinding process, the size of the beads must be proportional to the size of the agglomerates. In this way, the beads will not go into the potential spaces between the large agglomerates, since they would lose the ability to impact against them.

Bead mills are used for large batches and can maintain semicontinuous output. Operation is similar to a ball mill but the vessel is smaller and balls are 3mm diameter zirconium dioxide beads, and mixing is at a higher speed producing more rapid output. Bar mills are especially useful for highly viscous (thick) millbases.
