In mineral processing design and operations 2016. 8.3.1 rod mill charge. rod mill charges usually occupy about 45% of the internal volume of the mill. 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.
grate discharge dry grate discharge wet overflow discharge wet figure 8.5 effect of mill filling on power draft for ball mills. the data is taken from rexnord process machinery reference manual, rexnord process machinery division, milwaukee, 1976 the effect of varying mill speed on the power drawn by the mill is shown graphically in figure 8.4
rod mills for coarse grinding fl. most discharge via trunnion-overflow; volumetric loading is similar to that of a ball mill design standards for drive components are more demanding than ball mills; dry applications feature a peripheral discharge or an air-swept arrangement; typical operating speeds are slower than either sag or ball mills: tcs and
rod mill liners. rod mills are very similar to ball mills, except they use long rods for grinding media. the rods grind the ore by tumbling within 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 1.4 to 1.6.

therefore, the rod mill causes no excessive grinding, enabling you to produce products of relatively sharp particle size distribution curve. features. the rod mill is a grinding mill used for coarse grinding or fine grinding, which offers the following types and uses. peripheral discharge type. wet grinding type
grate discharge ball mill. grate discharge ball mill can discharge material through sieve plate, with the advantage of the low height of the discharge port which can make the material pass quickly so tha to avoid over-grinding of material. under the same condition, it has a higher capacity and can save more energy than other types of mills;
rods are placed parallel along the length of the rod mill. rods are 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 meters. rod mill
jun 23, 2020 converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. the grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. this is different to an overflow mill which holds the slurry and balls inside until
In some circuits, the rod mill discharge is fed first to the ball mill before process and instrumentation diagram for the SA mill discharge sump and use of an energy balance around the mill sump to estimate
rod mill principle. rod mill is usually selected in order to prevent over-grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine; In two stages grinding, the capacity of rod mill in the first stage grinding is larger than that of ball mill; In some cases, rod mill can replace short head cone crusher.
the rod mill usually uses diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. the length of steel rod is shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% 1%; the loading capacity of rod is about 35% 45% of the effective volume
rod mills are very similar to ball mills, except they use long rods for grinding media. 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 1.4 to 1.6.
