rod mills, how they function,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 charge by volume. the limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge.rod mill en by metso perumin,trunnion discharge mills are equipped with a replaceable liner in the discharge trunnion and a discharge spout attached to the trunnion so that the pulp or.unit operations in mineral processing,types of tumbling mills (2/3) • rod mills • mill-length rods as grinding media • used for primary grinding • mill length between 1.5-2.5 times its diameter • size reduction mainly achieved by compression between rods and attrition trunnion bearings 27 base, base bolts trunnion feed chute lining lining bolts gear.grinding mills and their types – ispatguru,the rod mill (fig 1) is a tumbling mill which is having a large percentage of its volume (30 % to 40 %) loaded with steel rods. the rods are placed axially in the mill and are loose and free to move within the mill. the internal lining of the drum has a series of lifters which raise the rods and drop them at a predetermined point..

description: trunnion liners are potential failure points in the mill circuit.liners protect the inside of trunnions from the abrasive action of the material slurry. worn liners can lead to erosion of the trunnions, mill head, and “fit” area. unless the erosion is stopped, form: loose liner / pre-fabricated; industry & application: crushers & grinding mills, mining, pipes / piping.optimization of mill performance by using,through the liner lifetime can lead to an improved liner design. however, the example of liner design and grinding efficiency uses the media charge angle only. other examples will explore the interaction between the pulp and the media load. influence of slurry properties and load behaviour in tumbling mills
