Feb 13 2017 Feb 13 2017 This fact should be carefully kept in mind when determining the capacity of a Steel Head BallRod Mill as this unit can carry a greater ball or rod charge and has potentially higher capacity in a given size when the full ball or rod charge is carried A mill shorter in length may be used if the grinding problem indicates a definite power input
Rod mills usually require greater operator attention It is important that the rods stay essentially parallel to one another If rods become misaligned grinding action is lost and more importantly rod tangles occur Maximum rod length is limited to about 61 m 20 ft This in turn limits the length diameter and capacity of rod mills The heavier rods acting upon the lifters and liners result in greater wear on the mill liners Rod mills normally carry 35 to 65 rod

The O1 tool steel grade has better machinability than A2 tool steel It must be hardened in oil which can be done at relatively low temperatures for good dimensional stability The polished finish offers a smooth surface with few imperfections The rod has been ground to achieve the precise shape and size Steel is an iron alloy with carbon
I got the 1 inch diameter 24 inch long 1018 carbon steel round rod It measured just a hair over 24 inches long And according to my calipers its slightly over 0999 in diameter Perfect size It does have a large UPC label but unlike a previous review the label was fairly easy to peel off
We are capable of grinding up to 1M 394 of thread in certain situations with minimal fixturing interference issues We are capable of 90 RH amp LH however at lead angles greater than 35 machine specifications become dependent on tooling part and wheel diameter coolant delivery and other fixturing interference issues

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 14 to 16 Rod mills accept feed up to about 50 mm 2 in and produce a product in the size range of 3000 to 270 mm 4 to 35 mesh
