KnowledgeScape. Model Predictive Control on a SAG Mill and Ball Mills The solution for the SAG Mill is an adaptive controller which controls mill load using direct mill weight measurement or indirectly from bearing oil pressure The solution automatically controls ore master feed rate and water addition to increase throughput while keeping mill load within
Ball Mills Components Custom Mill Inching Drive. The drive package consists of hydraulic power unit the necessary control valves and the final reduction unit cw a fail safe park brake. The maximum design output torque is 60000 lbft and the maximum output speed is 2 RPM. This equates to a mill speed of .15 revolutions every minute 7
2018-5-29rougher head feed is a combination of multiple ball mill hydrocyclone overflows and therefore does not represent the performance of any individual ball mill circuit. Thus the rougher head stream samples cannot be used in a ball mill control strategy for real-time particle sie control
Mine to mill optimisation effect of feed sie on mill throughput No. 48 SRK Consultings International Newsletter One of the most valuable aspects of blasting is the generation of very fine particles e.g. smaller than 12mm that will pass through the primary mills and onto the secondary ball mill circuits alleviating a common bottleneck
Control does not have to be what it was 30 years ago and with KnowledgeScape leading the way in automated process optimiation higher throughput and increased reliability are now possible. Utiliing a MillScanner results in better grinding clear vision of the mill contents at all times reduced steel and power usage longer liner life
