It is recommended to use a similar high gold content alloy when casting.
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.

Tumbling mills are machines used in mining, chemical, and construction industries to reduce the size of solid materials by using the principle of impact and attrition. They consist of a rotating cylinder, which contains a charge of loose grinding media.As the cylinder rotates, the grinding media falls, collides, and crushes the materials inside the cylinder.
— 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.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
