As one of leaders of limitation on rod mill diameter industry, SBM always seeks innovation & excellence.
For seamless pipe, there is a limit of 10% by weight (mass) over the nominal weight. Note that this limits the average wall thickness of the seamless pipe to being no more than 10% heavy, but does not limit the specific maximum wall thickness at any given point. There is no maximum thickness or weight limit .

Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.

Jul 20, 2019· A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size.

size F80 of 152 mm to 80% passing 1.7 mm, and a simple adjustment procedure in case the SAG product size needed to be adjusted. Bond rod and ball mill work indices are readily converted to pinion energy for rod and ball mills but not for SAG mills. Reproducibility, while not studied in this paper is clearly a part of the meaningfulness of the data

Rod mills have become niche comminution devices since about 30 years ago. Because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling (a potentially deadly failure for those tasked with rectifying the problem) rod mills have a maximum installed power of about 2.5 MW.

With the advancement of technology in rolling mills, the size of rolling mills grew rapidly along with the size of the products being rolled. One example of this was at The Great Exhibition in 1851, where a plate 20 feet long, 3 ½ feet wide, and 7/16 of an inch thick, and weighing 1,125 pounds, was exhibited by the Consett Iron Company.

If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about 6.1 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.

In recent years, rod mills have found increasing use in preparing ball mill feed. The rod mill is exceptionally well suited to handle coarse feed and to control the top size of the product. Rod mill products are generally coarser than those produced in a ball mill.

Table II gives rod length to mill diameter ratios for the larger diameter rod mills. 6.8 meters (20 feet) Is a practical limit on the length of good quality rods (that is rods that will stay straight in the mill and will break in to pieces that will discharge from the mill when worn).

Nov 13, 2016· Wire and Rod Drawing Process for Steel . Drawing of wire from steel rod is a metal working process used for the reduction of the cross-section of the rod. Similarly rods are drawn from steel rounds of larger diameters. During drawing the volume remains the same and hence there is increased in the length of the drawn wire or rod.
