The middle screen may direct the next largest rock size to a conveyor for stacking, while the bottom screen catches the smallest desired rock size, allowing fines and dust to fall through. Additionally, a portable plant may also have a grizzly deck installed before its impactor, which is a specific type of screening system that is used to ...
In the mineral processing sector, a common approach to expanding a SAG mill circuit is the addition of secondary or tertiary crushing to reduce the size of the mill feed. The addition of pre-crushing can increase the throughput of an existing SAG mill circuit by 10% to 30% or more, depending on the nature of the ore and the crushing
SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill.

b) Semi autogenous grinding in which the pebble fraction of mill discharge (+½ in.) is taken out through pebble ports for separate crushing and ball milling. The minus ½ in. fraction of mill discharge is recycled to the SAG mill through a classifier. The circuit is called SACB: Semi autogenous/ Crusher/Ball mill.
