  • Optimizing your SAG mill operation

    In turn, this leads to a higher rock to ball ratio, resulting in insufficient grinding energy and a further increase in load inside the mill Pebbles flow-back; Similar to slurry flow-back, the pebbles flowing back into the mill increase with larger pebble port or grate slot size...

  • SOLUTIONS TO CHAPTER 12: SIZE REDUCTION EXERCISE 12

    Table 1231 gives information on the size reduction of a sand-like material in a ball mill If the values of specific rates of breakage Sj are based on 5 revolutions of the mill, determine the size distribution of the feed materials shown in Table 1232 after 5 revolutions of the mill Table 1231: Results of ball mill tests Interval (μm)...

  • Dry Grinding VS Wet Grinding

    Dry Grinding VS Wet Grinding , These observations are of some interest in view of a theory of the internal dynamics of the ball mill, propounded by one of the present writers, since that theory suggests that when the quantity of solid material is small in relation to the volume of the ball charge, the particle size reduction might be small ....

  • Introduction to Mineral Processing

    Flotation circuits are often operated at a pH range of 75 to 115 The exact range at any given plant is optimized for the ore at that site Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite Particle Size The particle size to which the ore is ,...
