  • Fully Autogenous Grinding At Unki Mine

    Milling, realizing savings in both power requirements and grinding media consumption. The original mill sizing had been done with fully-autogenous milling in mind, but allowing for flexibility and mitigation in case of varied mining fragmentation. Since attaining steady state, target grinds have been achieved.

  • Autogenous Grinding Mining Fundamentals

    The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media the rock itself.

  • Grinding Mills For Mining And Minerals Processing Metso

    Autogenous grinding tests were run in a 10-ft x 4-ft Rockcyl mill. The principle of prepared feed and media was utilized to determine how coarse a feed could be commercially fed to a rock mill. Secondary rock milling was expanded toward the particle sizes of primary milling while still utilizing the practices of secondary milling.

    The closed circuit test mill was installed in an operating plant in parallel with existing conventional rod mill-ball mill circuits. Three stages of open circuit crushing were used to prepare rod mill feed. Grinding media was selected from various areas of the mine and tested separately. Impact tests on the three basic types of ore give Work Indices varying from 14.8 to 9.1 with two types appearing to be suitable as media and the third type questionable. The test mill was fed plant run ore with an average Work Index of 16.

  • Ag Autogenous Grinding

    Critical size buildup occurred in the first series of tests run, with a feed 80 passing 1 in. The size of media required for this size feed could not be obtained from the discharge of a primary crusher in commercial practice.

  • Grinding Mills Types Working Principle Amp Applications

    Using mill feed averaging 80 passing 58 in. critical size buildup occurred only when there was an excess of tramp oversize due to bin segregation and when using soft ore for grinding media. Screening mill feed at 1 in. square mesh solved the problem. It was established that rock milling could be applied to the product of a closed circuit tertiary crusher.

  • Case Boliden Autogenous Mill Application 131017

    Media all plus 5 in. square and averaging 6 in., weighing 1015 lb. was found to be ample to perform the desired grind. Depending upon the type of ore used as media the average rate of media addition was 8 to 12 of the total feed rate, new feed plus media. Mill power was used as a guide for media additions.

  • Grinding Mill An Overview Sciencedirect Topics

    The test mill drew maximum power with about a 40 load and was run with from a 35 to 40 load. With no critical size buildup and with controlled rate of media addition there was no need for crushing in the mill so the load could be carried at near maximum power level. The media wore through the critical size range at least as fast as critical size material was generated. Critical size material not being in the feed must be generated in the mill and is probably only a small percentage of the total mill charge.

    The Bond Work Index Formula was used to determine the operating Work Indices for the test rock mill and the parallel rod millball mill circuits. This formula, taking into account feed size, product size and power, proved an accurate tool for comparison. The operating Work Indices compared favorably and checked laboratory Work Index data.

    Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5-8217 diameter mill had both pebble ports and 8221 wide slotted grates. The plus 8221 mill product was crushed in a cone crusher and returned to the mill feed along with the minus 8221 plus 4 or 6 mesh fraction. Tests were run with a short mill, inside length of 26-388243, or diameter-to-length ratio of 2.50 to 1. The same mill was then lengthened to 48-388243, diameter-to-length ratio of 1.36 to 1.
