Jun 24, 2015 As a means of controlling splash and to prevent unruly rods from moving out of the mill a discharge plug or plug door arrangement is furnished. The use of this construction permits pulp to discharge freely around the annular opening between the plug and the discharge trunnion liner
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. 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

Aug 29, 2013 Discharge Arrangements. Metso Rod Mills are built in sizes from 3’ to 14’ shell diameter with shell lengths 1 1/2 to 2 1/2 times the diameter, depending on upon the mill
Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill length = 7 meters. Rod Mill
Jan 01, 2016 The design characteristics of industrial rod mills are similar to ball mills. Most rod mills used in mineral processing are of the overflow discharge type as illustrated in Figure 7.2a. Centre peripheral (Figure 7.2c) and end peripheral discharge mills (Figure 8.1) are also in use.The feed end is generally fitted with spout feeders, scoop feeders, double scoop feeders or drum feeders

Another purpose is an autogenous grinding mill having a peripheral discharge. ... until the particles strike the inside of the mill or the material being carried along by the mill liner. This is followed by lateral or arcuate impacting imparted by the lifter bars. ... Screening discharge device for rod and ball mills US3078049A (en) * 1959-06
In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further
Rod mill is a grinding equipment with steel rod as grinding medium. It is used to coarse grinding and suitable for fine crushing and coarse grinding in first stage of open circuit grinding.
