Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Dry ball milling also uses less energy than wet ball milling, which can lead to reduced operating costs. However, there are a few disadvantages to dry ball milling as well. One downside is that dry ball milling can create more dust than wet ball milling. Additionally, dry ball milling can lead to a slightly lower quality final product.

The advantages Wet ball milling has over dry milling are higher energy efficiency, lower magnitude of excess enthalpy, better heat dissipation and absence of dust formation because of the aqueous environment it is being performed. Particle Size Reduction Milling the powder in the wet or dry state produces different results.

The increase of the milling speed reduces the crystallites size in case of wet milling. In the case of dry milling, the crystallite size admits a maximum at 450 rpm. The crystallites are smaller in dry milling. Zhang et al. [11] have attested that dry milling and high milling speed were the key parameters for small WC crystallite size.
