Comminution Circuits for Gold Ore Processing

The classic crushing circuit prepares primary crushed ore for secondary milling, or heap leaching, by using two stages of crushing. Most typically, stockpiled primary crusher product is reclaimed and fed to a secondary crusher. In turn, the product of a secondary crusher operating in open circuit is screened, with oversize fed to a tertiary ...

Working Principle of Crushers

In the same manner the crushing effort, and demand for power, becomes greater as the centre of gravity of the rock mass moves downward in the crusher. Gyratory Crushers are heavy-duty machines run in open circuit (sometimes in conjunction with scalping screens or grizzlies). They handle dry run-of-mine feed material as large as 1 m.

Crushing Circuit

Open circuit crushing on the other hand involves a single pass of the material through the crusher. Closed circuit crushing has the advantage of greater final particle size control while open circuit crushing saves time and energy.

Ball Mill Grinding Theory – Crushing Motion/Action Inside

(d) Closed-circuit crushing will always have the advantage over open-circuit crushing, in that the maximum-size particle produced will be much nearer the average size. This is a desirable condition since the size of the balls making up the charge must be computed on the maximum-size particles in the feed rather than the average size.
