The most common secondary mill is a ball mill in which relatively fine feed particles ( mm top size) are ground in a charge consisting predominantly of steel balls. Mills can be operated in open or closed modes (which refers to whether the product is size separated in some way with the oversize fed back into the mill).

The Multotec hydrocyclone technology range comprises hydrocyclone diameters from 25 to 1 400 mm. Most of these diameters can accommodate a range of cone angles, while different vortex finders and spigot diameters are standard for all diameters. Small diameter hydrocyclones (up to 100 mm) are manufactured mainly from polyurethane, while larger ...
