The crusher in closed circuit is then used to reduce the size of the critical size material and return it to the mill. As the pebble ports also allow steel balls to exit, a steel removal system (such as a guard magnet, Chapters 2 and 13 Chapter 2 Chapter 13 ) must be installed to prevent them from entering the crusher.

ABC closed circuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill.

Before the advent of the cone crusher the usual practice was to make a 2-in. product in two steps consisting of a primary breaker of the jaw or gyratory type followed by a secondary gyratory crusher. If anything smaller were desired, a third stage was added comprising coarse crushing rolls in closed circuit with a screen.

Both open and closed circuit crushing is employed. For close circuit the product is screened with a mesh size much less than the set. The following figure is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed ...

Several different circuit configurations are adopted in industrial installations, including open or closed circuits with a classifier, stand-alone mode (single-stage), or coupled with a ball mill in SAB configuration . Full secondary pre-crushing of the fresh mill feed is an effective alternative to increasing the SAG mill throughput .

In turn, the product of a secondary crusher operating in open circuit is screened, with oversize fed to a tertiary crushing circuit, typically operating in closed circuit with screens. Variations or alternate configurations are common, but the product of a typical tertiary crushing plant is nominally passing 13 mm.
