Can the diameter of the steel rod of the rod mill be greater than 1m?

The rod mill In the rod mill high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls This mill gives a very uniform fine product and power consumption is low although it is not suitable for very tough materials and the feed should not exceed about 25 mm in size

Product Introduction

Ball Mills Mineral Processing amp Metallurgy

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

Silver steel round bar is manufactured from high carbon bright tool steel it is called s ilver steel due to its bright finish it does not contain any silver This rod product is manufactured with closely controlled analysis for ensuring uniform machining properties and consistent response to heat treatment it is also centerless precision

Diameters are going to range from 5mm to 15mm with most adhering to the international ISO standards allowing sizes to range from those indicated above and upon reaching 15mm in increments of 5mm until that point advancing in increments of 1mm until a size of no greater than 20mm All steel wire rods is formed into coils and without break

O1 Tool Steel Round Rod Polished Finish Precision Ground

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

Although similar in operation a rod mill is often more effective than a ball mill as it requires lower rotational speeds and less steel to achieve the same results It is however limited to maximum rod and drum lengths of approximately 20 feet 6 meters and is generally only used for wet grinding processes

Rod mills how they function Mine

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

The rod mill In the rod mill high carbon steel rods about 50 mm diameter and extending the whole length of the mill are used in place of balls This mill gives a very uniform fine product and power consumption is low although it is not suitable for very tough materials and the feed should not exceed about 25 mm in size
