Ball mill grinding circuits are essentially multivariable systems characterized with couplings, timevarying parameters and time delays. The control schemes in previous literatures, including detuned multiloop PID control, model predictive control
· Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.
Closed circuit ball mill Basics revisited Request PDF. The summary results of the four tests are given inTable 1Test 3 simulates a ball mill in closed circuit with high fre quency screens, which typically have in the order of 100 per cent circulating load and 90 per cent classifiion efficiency.
first mill operating in an open circuit and the second mill, in a reverse closed circuit. The second grinding circuit involved two mills operating in parallel, both in direct closed circuits. The results indied that the parallel circuit produced 20% less slime than the series circuit, with an additional % throughput in the flotation feed. No

The circuit (Figure 3) consisted of two parallel lines, each employing singlestage primary milling followed by rougher and cleaner flotation using Wemco flotation cells, the tails of which were thickened and pumped to a tailings dam. The milling approach, termed runofmine ball milling employed mills receiving runofmine material,

MODEL PREDICTIVE CONTROL OF SAG MILLS AND FLOTATION CIRCUITS *Michael G. Forbes and Bill Gough . ANDRITZ AUTOMATION Ltd. 100 – 13700 International Place Richmond, BC V6V 2X8 Canada (*Corresponding author: ) ABSTRACT . Precise control of SAG mill loading and flotation cell level is critical to maximize production and
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG ...
