High-speed stirred mills are utilized to grind particles below 10mm. Grinding sulphide minerals to as low as 10mm achieve adequate mineral liberation for successful downstream mineral processing operations, such as flotation and leaching. Particle breakage mechanism such as fracture or abrasion, determines the morphological surface features of the product particles.

Shaft journal bearings for compressors operating in most process services and some air applications are located "outside" the case, rather than being an inside bearing. This is important for maintenance, as well as for reducing the problems in keeping oil out of the gas stream; although this problem still exists, but not to such a great extent.
