Ball mills can be as small as lab-scale mills or as large as industrial mills with a diameter of up to 8 m. The mill's capacity is dictated by its volume. The volume depends on both diameter and length. 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 ...

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5. The
1. Introduction. Ball mill is one of the most commonly used mills for the crushing and grinding of mineral ore. It is generally used to grind material down to the particle size of 20 to 75 μm and can vary in size from a small batch mill up to a mill with outputs of hundreds of tonnes per hour.
Usually, the ball-filling rate is about 40%. The mill balls' size is initially 30–80 cm in diameter but gradually wears away as the ore is ground. In general, the ball mill grinder can be fed either wet or dry. The ball mill machine is classed by electric power rather than diameter and capacity.
