  • Charge behaviour and power consumption in ball mills

    Abstract. Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5-m ball mill. Specifically, changes in charge fill level, lifter shape (either by design or wear) and lifter pattern are analysed.

    Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and

  • Use of drilling performance to improve rock-breakage

    3/1/2020· Abstract. In a hard-rock mine, blasting is an important rock-breakage process that impacts energy consumption both in downstream comminution processes and mine productivity. Optimizing the blast fragmentation to improve rock-breakage efficiencies during crushing and grinding is key to mine-to-mill (MTM) optimization.

  • Mining comminution crusher, ball mill, and advanced

    Based on the density of the rock body being blasted, the drilling pattern, and a whole host of other factors, there will be a range of rock sizes included in the run of mine (ROM) ore. Smaller pieces will fall through the rock crusher and make their way directly to the SAG mill or ball mill.

  • Combined DEM and SPH simulation of overflow ball mill

    Discharge of finer rock, pebbles, ball scats and slurry from mills and its flow through trommels and into other processing operations all affect the performance of overflow ball mills. Modelling of the coarser rock components and the grinding media is best done using the Discrete Element Method (DEM) while modelling of the slurry component is best done using a compatible particle method such

  • Comparison of HPGR-Ball Mill and HPGR-Stirred Mill

    Abstract. In the past 20 years, the energy-efficient comminution technologies, including high pressure grinding rolls (HPGR) and high speed stirred mill, have been developed and adopted in the hard-rock mining operation in order to reduce the energy consumption and improve the process performance.

    10/20/2008· Abstract. The size distribution produced by the ball milling of various crystalline and non-crystalline materials, showed that initially there was a fairly even distribution over the size range up to 355μm. The slopes of these lines were steep for rock salt and sucrose (crystalline materials) indicating that milling was rapid, whilst with
