REDUCTION RATIO FOR BALL MILLING | worldcrushersMay 03, 2013· reduction ratio of rod mill ? Grinding Mill China This indicates that the rod mill reduction ratio is much larger than those at normal condition, and ball mill reduction ratio is much smaller ? More detailed ball mill reduction ratioRod mills, how they function - Mine EngineerComRod mills operate at lower speed than ball mills since the rods are rolled and not cascaded For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore The rod charge must be maintained in good working condition, and broken and worn rods must be removedcalculation of the ball mill reduction ratioThe reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the oreThe usual reduction ratio is about 8 According to Bond [4], the reduction ratio is a function of length and diameter of the mill The optimum reduction ratio, R RO, can be written asRolling processesthickness reduction, rolling usually increases work width This is called spreading, and it tends to be most pronounced with low width-to-thickness ratios and low coefficients of friction, so the volume of metal exiting the rolls equals the volume entering 53 Where w o and w f are the before and after work widths, mm (in); and L o and L fSpecial Bar Quality Steel - TimkenSteelIn-Line Forge Press and Rolling Mill The 3,300-ton in-line forge press enhances center soundness of a larger cross-section of special bar quality steel The process - combined with rolling - improves shape and size control to deliver consistent foot-weight and size toleranc This helps improve the dependability and performance of criticalcalculation of reduction ratio ball millevaluation of grinding circuit performance in esfordi phosphate , - S calculations, the reduction ratios of rod and ball mills were 6465 and 115, which show high , the ball mill is increased and therefore its reduction ratio is higherReduction Ratio Of Ball MillReduction Ratio Conical Ball Mill The reduction ratio R in rod mills varies from 2 and 20 depending on the characteristics of the usual reduction ratio is about 8 According to Bond 4 the reduction ratio is a function of length and diameter of the mill >>REDUCTION RATIO FOR BALL MILLING | Crusher Mills, Cone ,The average values of reduction ratios for rod and ball mills were equal to 6465 and 115, with standard deviation of 391 and 003, respectively volume ratio of grinding ball in ball mill
