To conduct a test in either ball mill, specific amounts of liquid and ore or rock are selected to provide a slurry. The ratio of ore weight to total surface area of the specimens is kept the same in both mills for comparison of results. Typically, 1.13 L of liquid, 3.8 L of ore, and six specimens are used in the larger ball mill.

Design. Ball mills consist of a container, usually cylindrical, filled with grinding balls, which is connected to an electric motor, which spins the container. The container is made of metal or plastic. The grinding media (balls) are often made of lead - antimony alloy, or tungsten carbide. Steel is usually avoided, since it will spark.

The average age of the ball mill is one year and seven months, according to data provided specifically for the relining of the ball mill. The liner of the ball mill will be replaced on May 19, 2023, according to the results of an analysis of liner wear conducted on June 23, 2022. This means that the ball mill will be one year and five months old.

Traditionally, mill media wear rate is evaluated by measuring the media level in the mill, or by removing media charge and weighing it after a certain number of hours. As mentioned above, the mill was stopped after 24 h (one cycle) with a total of 24 cycles for each ceramic ball type. Grinding tests were carried out for 24 days (576 h) and ...

A ball mill is another type of milling machine that uses balls to crush material. The ball mill is made up of a hollow section that spins down either a horizontal or a vertical axis. The section is packed with balls. The materials to be crushed are added and the balls move around inside the mill, colliding with the materials.
