Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. The critical speed (rpm) is given by: nC = 42.29/√d, where d is the internal diameter in metres.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

This approach is based on a hybrid numerical model of a 24-degree-of-freedom gearbox, simulating one gear train and two drive shafts. The impact forces of the mill drum are modelled by a discrete element method (DEM). The ball-filling rate (Fr), the mill speed (Nr), and the ball size (Db) are considered to study this phenomenon.

There are two well-known modes in which the ball charge moves inside the mill: cascading and cataracting. The cascading motion of ball charge forms a compressive zone inside the mill where particles may break under slow compression. The cataracting motion, on the other hand, causes the particles to break under high-impact forces.

Principle. Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).
