    controller presented in this paper is perhaps the first successful implementation of MPC for ball mills described in the literature Current MPC software has its roots in a set of heuristic, modelbased control algorithms proposed and implemented within the process industry in the late 1970s (Richalet et al, 1978; Cutler and Ramaker, 1980) Subsequent to that, many important developments inBall mills are usually the largest consumers of energy within a mineral concentrator Comminution is responsible for 50% of the total mineral processing cost In today’s global markets, expanding mining groups are trying to optimize mill performances Since comminution is concerned with liberating valuable minerals for recovery in the separation process, it is crucial to run the mills at theOptimization of mill performance by using· Every operator should strive (by design, or redesign) for a high circulating load in their ball mill circuits, and this paper clearly shows why “Pulp Densities Within Operating Ball Mills, ” by Davis, E W, 1945, Issued as Technical Paper 1843 of AIME, Mining Technology, May This is perhaps the only work ever conducted that provides the actual material contents of a continuouslyThe essential grind CIM

  • Paper # 25 Copper Mountain Overview on the Grinding

    MILL DRIVES ABSTRACT This paper will first give a short overview of the Copper Mountain project in British Columbia, which just has started commercial operation earlier this year The grinding process with one 34' x 20' SAG mill and two 24' x 395' ball mills will be briefly discussed All three mills are gear driven by a ring gear, dual pinion and two low speed synchronous motors Copper· Ball mills are a special instrument used to break up hard solids into a fine powder They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill Using a motor, container, belt, caster wheels, and some basic buildingHow to Make a Ball Mill: 12 Steps (with Pictures) wikiHowMills Office Productivity Social Responsibility Practices are based on the principle that businesses have an important role to play in addressing the social interests and sustainable development goals of their community Learn More We are here to help Our customer care team would love to help you with any request from Monday Friday 8am5pm To contact customer care please call 1800665Mills Office Productivity: Office Supplies British Columbia
