live chatSimplifying wet grinding with Metso AG/SAG mills AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids) AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball millOptimum protection of your mill heads The role of these liners is to protect the mill heads against wear and offering the longest possible lifetime with the optimal grinding efficiency The design will depend on: Drilling pattern on mill heads Mill speed (rpm) Maximum grinding media diameter (mm) Grinding media filling degree (%) Key benefits:.

live chatModel 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 .Want to control grinding mill feed, Automatically? The MillMinder Audio Signal Converter listens to the sound levels generated by the impact inside the grinding mill and provides the operator with an output signal that allows automatic material feed control to the mill.

live chatThe Selection and Design of Mill Liners Malcolm Powell*, Ian Smit#, , Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour In this case the liners sections are 35 t eachSAG mill heads and more detailed specifications for non-destructive testing (NDT) of welds Mill drives: the desire for increased power and the associated limits and conditions 3 , SAG mill is rated at 29 MW and 78% CS, with a 42 ft dia mill built but not yet operational The more recent option.

live chatThe Intelligent Mill Liner Bolt Up until now, SAG mill operations have lacked the means to intelligently determine mill liner replacements, other than the "blind" option of shutting down production, clearing the feed chute and doing a full, physical inspection of the mill lining and its wear depthmills in the older plants that had many mills in parallel In fact this is generally still the case in the multi-stream plants, where mill liner design and selection is only tackled on a cost consumables basis However, the gains to be had through good liner design and selection are just as great as on the large SAG mills.

live chatThese equations are used by SMCC Pty Ltd to estimate the specific energy of AG/SAG mills under all normal operating conditions, eg ball load, mill speed, feed size and ore hardness and for all .Developments in SAG Mill Design and Operation Over the last few years, SAG mill manufacturing technology has advanced rapidly The bounds of mill size have been pushed from two directions Firstly, the advent of ring motors has removed the constraint applied by the power that a.
