Ball mills are available in various sizes and capacities, and their technical specifications can vary depending on the manufacturer and model. Some of the key technical specifications include: - Diameter and Length: Ball mills are typically available in diameters ranging from 0.6 meters to 4 meters and lengths ranging from 1.5 meters to 12 meters.

If a grind size of 30 µm (D90) is the objective, the most suitable ball size would be between 20 mm and 30 mm. If smaller particles are required, the balls must be removed and replaced by smaller ones for a second process step. As larger balls could crush smaller ones, it is not advisable to combine different ball sizes in one milling process.
