In a ball mill circuit, the output can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two inputs to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

The designed ball milling circuit product is 80% passing 150 m. Several large tonnage copper porphyry plants in Chile use an open-circuit SAG configuration where the pebble crusher product is directed to the ball mills (SABC-B circuit). The original grinding circuit at Los Bronces is an example: the pebbles generated in the two SAG mills are ...

The on-line sampling system and ultrasonic particle size monitors were installed on each hydrocyclone battery in …
primary wet autogenous mill (WAM) and a series of ball mills. WAM is customary chosen either based on examination of analogous equipment specifications, or from the evidence of very expensive commercial and semicommercial testing that requires large sampling, much time and high investment [1].

Following the upgrades in the SAG mill circuit, sampling and modeling of the ball mill circuit identified a bi-modal hardness characteristic of the ore. valuation with both MetCom and JK SimMet E lead to changes in the ball make up size from 75 mm to a 50:50 mix of 75 mm and 38 mm.
This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 m). Furthermore, the operating capacity of the ball mill has reached 90% capacity, running at near full load.
