For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (make-up balls) DM function of the feed size xG (80% passing size - µm), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):

When the tube mill was first introduced, grinding was done in open circuit; i.e., the ore was ground to pass the limiting screen size by one passage through the mill. It was found, however, that if sufficient time of contact between the ore and grinding media were provided to ensure that no unground particles (or oversize) discharged from the ...

air separator mill with drying chamber for iron ore grinding. The single-compartment mill is ideal for the grinding of fine-grained feed material. One typical application is the combined grinding and drying of iron ore concentrate with a high feed moisture content (up to approx. 8 %). High-efficiency separators minimise the power
