Rod mills used products maximum sizes 4 mesh 35 mesh. rods rod mill contact result preferentially grind largest particles relatively narrow range distribution; tramp oversize extreme fines. Figure 1 shows various types rod mill discharge arrangements.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
classifier rod for rod mill. Question a twostage grinding circuit using a rod mill in an open circuit with a ball mill in a closed circuit with a cyclone classifier is used to grind tonnes per hour of ore sG the circuit layout is illustrated in the figure below assuming that the circuit is sampled and the results are shown in the table below rod mill discharge ball mill
The SAG mill was designed to treat 2,065 t h 1 of ore at a ball charge of 8% volume, total filling of 25% volume, and an operating mill speed of 74% of critical. The mill is fitted with 80 mm grates with total grate open area of m 2 (Hart et al., 2001). A m diameter by m long trommel screens the discharge product at a cut size of ca. 12 mm. Material less than 12 mm falls into a cyclone feed sump, where it is

rod millrod milling machine idee. A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting,. The discharge die gap a of the grinding machine is used for the ground solid matter in this formula.,But note that the term ''''rod mill'''' is also used as a synonym for a slitting mill, which makes rods of iron or other metal.
The rod mills, which have a discharge port in one end of the shell, are called quot;End Peripheral Discharge Typequot; ( type as per ), while those having a discharge port in the center of the shell are called quot;Center Peripheral Discharge Typequot; ( type as per Fig. 2).
The CIW is a Small Ball Mill thats belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears. All these mills are standard with white iron bar
mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.
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 openings where
Apr 09, 2015#0183;#32;The rods crush the material and as the charge passes through the mill, it is reduced in size to approximately 2 mm to mm. The mill can be fed from one end with the product removed from the other end or, alternatively, the mill can be fed from both ends with the discharge at the centre.
Most discharge via trunnionoverflow; Volumetric loading is similar to that of a ball mill (3035%) Design standards for drive components are more demanding than ball mills; Dry applications feature a peripheral discharge or an airswept arrangement; Typical operating speeds are slower than either SAG or ball mills: 6570% TCS (wet) and 6263% TCS (dry)
