calculating a grinding circuits circulating loads based on screen analysis of its slurries. compared to %solids or density based circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or for a recent ball mill is shown in figure mill suppliers define the starting torque at an angular displacement of the charge. the cascading point of this mill is at angle of this implies that a motor connected through a reduction be capable of transferring 120% of its rated full load torque when it has turned through revolutions.
calculation Of load torque In cement balls mills. calculation Of load torque In cement balls mills. ball mills these mills use forged steel balls up to inches 127 mm in diameter to crush and grind the material mill length is two or more times its diameter rod mills steel rods up to inches 114 mm in diameter and slightly shorter then the mill length are used for the grinding process mill the milling process definitions cutting speed,v indicates the surface speed at which the cutting edge machines the workpiece. effective or true cutting speed, indicates the surface speed at the effective diameter .this value is necessary for determining the true cutting data at the actual depth of cut .this is a particularly important value when using round insert cutters
