1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.

Principle of Ball Mill Operation. The ball mill operates by rotating a cylinder horizontally and partially filled with balls. The cylinder's rotation causes the balls to cascade and fall back into the mill, generating impact and friction against the material to be ground. The following are the key components of a ball mill: 1.

According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, and ceramics. It works on the principle of impact and friction between rotating balls and the powder materials. The ball mill consists of a rotating drum and a hollow cylinder filled with grinding media, typically ...
The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.
Fig.1: Cascade Operation in Ball Mill (a) Low Speed (b) High Speed (c) Correct Speed: The material to be ground is fed from a hopper at a 60° angle and the product is discharged through a 30° angle. As the shell rotates the balls are lifted on the rising side of the shell and cascade down (or drop down onto the feed) from near the top of the ...
Optimised milling throughput – Controlling the mill fill level rather than bearing pressure increases milling capacity; Increase mill efficiency – Improve mill power utilisation by grinding optimally; Reduce opex – Reduce ball consumption/ton milled and reduce liner wear by operating the mill at an optimal fill level

The replacement of the ball mill liner is a very cumber some and technically high-quality work. In addition to the above mentioned replacement techniques, the personal safety of the staff is particularly needed. Correct ball mill liner replacement operation can improve the use time of the ball mill and ensure the safe operation of the ball mill.
Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface.
