#0183;#32;The correction is not always needed for high reduction ratios, but it is used if W i for the rod mill and ball mill is greater than 7. 7. Correction for low reduction ratio in ball milling. If the ball mill reduction ratio is less than 6, a correction factor, F 7, is applied: ()
Rod mill grinding rods of all sizes and length. High hardness, range is 45~55HRC Low bending, less than /m Dense microstructure, Bainite +Pearlite+Carbide Low breakage rate, more than 15000 times/ Low unit consumption, 40% reduction compared to unprocessed round steel

evaluation of grinding circuit performance in esfordi phosphate Sid. calculations, the reduction ratios of rod and ball mills were and, which show high the ball mill is increased and therefore its reduction ratio is higher.
Effect of Grinding Rod Media Load on Rod Mill the feed size was 54% plus 3 mesh with the 2#189; inch (64 mm) rods (reduction ratio over 40), and only 40% plus 3 mesh with the 3 inch (76 mm) rods (reduction ratio less than 30). This substantially coarse feed may have had a negative effect on mill efficiency, as indicated by Bonds reduction ratio correction factor. We also experimented with
Reduction ratio = 2 20 depending on material. Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% 65% range; Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = tons/m3; In wet grinding, the solids concentration 1s typically 60% 75% by mass. A rod in situ and a cutaway of a rod mill interior. [image: (135

Ball Mill Reduction Ratio Industry Crusher Mills Cone. Calculations the reduction ratios of rod and ball mills were 6465 and 115 which show high discrepancies from design values 23 and 75 for rod and ball mills. Grinding In Ball Mills Modeling And Process Control
A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wetgrinding rod millball mill circuit. Rod mills came into use in the United States beginning in 1900s and
Grinding rods, usually made of high carbon steel, are used instead of balls in rod mills. They are 25125 mm in diameter and may be circular, square or hexagonal in crosssection. They extend to almost the full length of the shell and occupy about 35% of the shell volume. In such mills, attrition forces predominate but impacts also play a part in size reduction. They are classed as

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of
