Our system effectively mitigates the number of variables in the control formula of your mill to optimise the performance of your operation.
Read MoreMine ore, simulation A grinding mill circuit forms a crucial part in the energy-intensive comminution process of extracting valuable metals and minerals from mined ore. The ability to control the grinding mill circuit is of primary importance to achieve the desired product speciﬁcation with regards to quality and produc-tion rate.
Read MoreJan 03, 2020 Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores. The grinding of ore is a highly energy-intensive process [1,2,3,4].In this process, the size of the particle obtained depends on the energy consumption of the ball mill.
Read MoreWorking principle. Ball mill grinding machine is a kind of horizontal drum-type grinding mill with external gear and double bins. Materials goes evenly through quill shaft in feeding device into the first bin, which has ladder lining or ripple lining with steel balls in different specifications.Steel balls are taken to a certain height by centrifugal force from drum rotation and then fall.

Iron ore processing for the blast furnace grinding mills water is added at this point to transport it 94 percent of the water is recycled while the rest is lost through evaporation fine grinding is achieved using these smaller mills bringing the ore to a similar grind.
Read MoreInside the mill and it is composed of balls, ore and water. The ball charge is a function of the bulk fraction of the SAG mill volume (Jb) occupied by balls the ore retained in the mill is the result of the volumetric ﬁlling which depends on the ore size distribution (spe-cially the +600 and the 600 +100), on the rotational speed (N Nc).
Read MoreJun 16, 2020 A particle size monitor can assist the mill operator to maximize the grinding circuit throughput as the milling conditions change due to variable ore processed at the mine. Particle size monitors use ultrasonic attenuation technology to provide particle size analysis of a mineral slurry stream. They can help ensure the final grind target at.
Read MoreSemi-Autogenous Grinding mills can be optimized for maximum ore throughput or maximum grinding energy efficiency. In both cases, precise control of the mill weight is critical. Model predictive control provides an additional tool to improve the control oSemif -Autogenous Grindingmills and is often.
