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).

CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch.
