  • How to Reduce Steel Consumption in Grinding Mills

      However, the actual amount required for a particular ore would probably be different For example, in a sulfide concentrator, addition of lime to the pyrrhotite regrind mill reduced ball consumption by 40% The lime was added at 06 kg/t of ore which changed the feed pH = 82 to discharge pH = 91 Composite Materials for Ball   An iron ore mill relies on the grinding and impact of grinding balls to complete iron ore crushing The operating process of an iron ore mill is as follows: first, the ores are poured into the mill, and both the ores and the grinding balls are lifted by the lifting bar arranged on the wall of the cylinder body to a certain height, after which they fall onto the bottom of the mill to complete the crushingFriction and wear of liner and grinding ball in iron ore   Hence, grinding the iron ore blend at 11 min and 9 min is not desirable, since the amount of energy supplied at these two grinding times is more than the required energy for desired particle size reduction and leads to increased energy consumption by the ball mill, which is not economicalInvestigation on Iron Ore Grinding based on Particle

  • Investigation on Iron Ore Grinding based on Particle

      The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore Grinding experiments were conducted according to Bond’s standard test procedure []For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method  To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly In order to reduce the feed size of ore, the particle size of crushing product must be small, that is, "more crushing and less grinding"10 Ways to Improve the Grinding Efficiency of Your   Ball mills are progressively used to grind the ores for particle size reduction and to liberate valuable minerals from the ores The grinding of ore is a highly energyintensive process [1,2,3,4]In this process, the size of the particle obtained depends on the energy consumption of the ball Estimation of Grinding Time for Desired Particle Size
