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.

This is provided by a high pressure oil pump which delivers oil between the bearing and journal. The oil, injected under pressure, lifts the mill and helps to reduce the friction between the shoe and ring, providing alignment. The minimum oil viscosity for most mills is 44 cSt at 100°C and typically requires an oil with an ISO 460 Cst viscosity.

In mainshaft bearings, modular windturbine designs commonly use sphericalroller bearings (SRB) units that are more than 1m in diameter. Designers often select single SRB designs, one supported by a single main bearing and two torque arms that carry gearbox reaction loads. At least two factors contribute to early failures in mainshaft bearings.
