Generally, the length-to-diameter ratio of the mill, known as the L/D ratio, is between 0.5 and 3. Shorter mills are used for crushing coarse materials, while longer mills are utilized for grinding fine materials. The ball mill dimensions and capacity are determined based on the application, and the required throughput.
