Ball mill
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
The ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with grinding media (balls), which can be made of steel (chrome steel), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber.
When the mill rotates, the grinding media (balls) are lifted to a certain height and then cascade down, impacting the material to be ground. The grinding action is a combination of impact, attrition, and abrasion. The material is crushed by the impact of the falling balls and the friction between the balls and the mill's inner surface. The rotation speed of the mill is critical: if it is too low, the balls will not cascade effectively, and if it is too high, the balls will be pinned to the inner wall by centrifugal force, reducing grinding efficiency.
The size of the grinding media and the material to be ground, along with the rotation speed, determine the fineness of the final product. Ball mills are widely used in industrial applications due to their ability to produce a fine and homogeneous product.
