The designed ball milling circuit product is 80% passing 150 µm. Several large tonnage copper porphyry plants in Chile use an opencircuit SAG configuration where the pebble crusher product is directed to the ball mills (SABCB circuit). The original grinding circuit at Los Bronces is an example: the pebbles generated in the two SAG mills are ...
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
The estimate considered the entire circuit operating costs from primary crushing to final grind (rougher flotation feed). The estimate utilized C per kWh for energy cost, C1050 per tonne for the cost of steel media, a wear rate of 6000 h for HPGR roll tires, 72 g/kWh for SAG mill media and 52 g/kWh for Ball mill media.

2 Compared to a ball mill, a semi auto generous (SAG) mill utilizes less steel balls for grinding in addition to the ore (pieces of rock), and it is generally used as a primary or firststage grinding solution before ball mills. Reference [1] Rufli, M., van de Vijfeijken, M. Driving value: Sophisticated ringgeared mill drives from ABB (Part 1).
The SABC, an acronym for SemiAutogenous Ball mill pebble Crusher configuration, was adopted for the Sossego industrial grinding circuit under a nominal throughput of 1841 t/h for a product with an 80% passing size (P 80) of mm . Accordingly, a longdistance conveyor belt conveys the primary crusher product to a primary stockpile.
to an industrial semiautogenous (SAG) mill in Craig and MacLeod (1995, 1996), and the linear model predictive control for an industrial ball mill circuit in Chen et al. (2007). A robust nonlinear model predictive controller (RNMPC) was proposed by Coetzee et al. (2010) to control a ROM ore milling circuit. Full state feedback was assumed.

This circuit shows a semiautogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of 'critical size' material in the circuit. 'Critical size' material, also referred to as pebbles, represents material that does not selfbreak as readily as ...
reduction of pebbles. For mill speed the media displayed two common mode operations namely cascading at a low speed of 65% and cataracting at higher speed of 75%. The higher speed generated the least pebbles. Keywords: Attainable region, semiautogenous mill, ball mill, SABC circuit optimisation, pebbles, MODSIM®
High Pressure Grinding Rolls (HPGR) circuits have the potential to reduce these emissions by up to Megatonnes/year, or % when compared to the Semiautogenous/ball mill circuit alternatives.
