Rod millsnormally carry35 to 65% rod chargeby 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 they can cause rod tangling.

The following cost advantages should be considered when evaluatingrod mill grinding:Rod Millsuse low cost grinding media. Less power is required sincegrinding rodsare not cascaded and operate at lower peripheral speeds. Highergrinding efficiencyis obtained since there is less void space in arod chargecompared to any other grinding media.
New feed entering at one end of themillcauses therod chargeto spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling androlling rodsexpend most of their crushing force on the coarse fractions of the feed material and only to a lesser degree on the finer material filling the interstices in therod charge.
Eachrodmeasures almost five metres in length and weighs up to 240 kg.Rod millsare used extensively as primarymillsin many mines, with therodsacting as grinding media. As therodswear down, new ones have to be introduced regularly to ensure grinding efficiency is maintained.
To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of tangling Increases rapidly. For rod mills larger than 3.8 meters (12.5 feet) in diameter rod availability and quality have to be considered.
Rods are loaded or charged into a Rod Mill using a mechanised charger. The rod charger with extendable boom moves rods safely inside the trommel/trunnion before charging with a typical 30 seconds or less cycle time per rod. Rod Mill Charging - YouTube

Rod millshave an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface thanrods. The power needed to operate arodmill could exceed 30% of the power used in a ball mill. When they are worn,rodsmust not stretch but break in rather small pieces, so that they can exit ...
Jul 03, 2017· “Only two people are involved: one to operate the unit, and one to check that therodsfeed smoothly into the mill.” Another significant advantage is the reduced time taken to conduct therod charging; the complete process has been cut down from over an hour to just about 25 minutes.

Jan 03, 2014· Modern wirerod millsare high speedmillscapable of rolling of smaller dimensions at high production rates, while at the same time keeping investments and operating costs at the reasonable levels. As a rule, wirerod millsare designed for an annual output of between 300,000 t and over 800,000 t (two strandmills).

The mill vessel has a tilting hand operated mechanism for easychargingand discharging of material sample. This make the mill easy to operate Discharge the material once milled is done through a discharge chute with a stainless steel grid to separate the sample from the grinding media ( balls /Rods)
Arodmill is an ore grinding mechanism that uses a number of loose steelrodswithin a rotating drum to provide its attrition or grinding action. An orechargeis added to the drum, and as it rotates, friction between the tumblingrodsbreaks the ore down into finer particles.
