AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill Operator
Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns; The CenterPeriphery Discharge mill has feed reporting from both ends and the product The ore ball mill designed by our company, which is represented by gold ore ball mill and iron ore ball mill, is manufactured with highquality materials and advanced technology They have the characteristics of high efficiency, energysaving, green environmental protection, simple operation, stable operation, and low failure rate, and have a good reputation in the industryBuy Ore Ball Mill for Mineral Processing Iron Gold Ore Ball Mill2016年6月6日 It can be very difficult operationally to trade grind for throughput in an SAG circuit—once designed and constructed for a given circuit configuration, an SAG mill circuit has limited flexibility to deliver varying SAG Mill Grinding Circuit Design 911Metallurgist2003年7月1日 If the grate provides a high resistance to flow of slurry, then the mill will fill with an excessive amount of slurry to a level past where efficient grinding occurs, and the mill will “go off the grind” (Austin et al, 1984)Moys (1986) supported this view and stated that an excessive buildup of slurry would seriously affect autogenous mills as a large volume of dense slurry Slurry flow in mills: grateonly discharge mechanism (Part1)
