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 times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

Use perlite to aid drainage. Succulents and other plants sensitive to moist soil benefit from having perlite added to the potting compost. The perlite will trap air in the compost and encourage water to drain through, ensuring the plant's roots will never sit in damp soil. Mix perlite with compost at a ratio of around 1:4.

According to the generated energy, ball milling can be mainly classified as lowenergy ball milling and highenergy ball milling. The rotation speed of most planetary ball mills is 0~500 rpm, while highenergy ball mills can reach up to 1800 rpm. During ball milling, shear force, impact force, and friction force can be generated.
