Estimation of shear rates inside a ball mill

 · Shear rate resulting from the cascading motion was thus estimated to be 13 s −1 for the above ball mill. For the second type of motion, the velocity of a free-flight ball striking the mill shell was resolved into two components: the normal velocity which causes impact breakage, and the tangential velocity which results in abrasion.

What is a Rod Mill? (with picture)

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.

steel balls cascading

A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods. A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, ...

Mill Charge

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.

Two types of charge motion can be described Cascading and ...
