A Rod Mill has for Working Principle its inside filled grinding media, in this case STEEL RODS. These rods run the length of the machine, which is most commonly between eight and sixteen feet in length. The diameter of these rods will range from, when new, between two and four inches. The rods are free inside the mill.
the mass of rods in the mill. 8.3. A wet rod mill was loaded to 45% of its volume with a charge consisting of a gold ore and steel rods. The rods diameter was 70 mm. The mill had an inner diameter of 1980 mm and was rotated at 21 rpm with a rod load of 23.8 t.
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.
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. How you charging a rod 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.

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles.
No change in mill power draw was reported during the test. Bond (1950) made recommendations for the correct size of rod to be used, noting that oversize rods decrease the available contact surface area of the charge, and that undersize rods …
Here a Rod Mill has its daily 3.5" steel rods being added using a mechanised rod mill charger. The operator only has a few minutes to load the rods and rest...

On the fourth rod there is a change: on this rod you will put a bushing in the first slot, skip two slots, and put a hammer in the fourth slot. Then put a bushing in the fifth slot, skip two slots and so on. The reason for this change is that the hammer pattern repeats itself every four rods and four hammers.
The objective of the invention is to increase the efficiency of the loading rods in a rod mill and simplification of load terminals in the device due to a change in the construction of freight trucks; simplify the design of the device and reduction of capital costs by eliminating additional components and mechanisms, as well as hydraulic equipment.
Hack the butt off with a hack saw. Just be sure you secure the rod in a vise of some sort and make a good measurement before cutting. You can also score the line to help avoid any epoxy or graphite chipping while you saw. You will need to weight the butt afterwards because it does change how tip-heavy the rod is.

Further fast change-over is the key to the flexibility of the mill. The mill is to be able to convert to the next order while still processing the current one and change the line from one product to another with virtually no downtime. A typical layout of wire rod mill with a capacity of 400,000 tons per year is shown in Fig 1.
1. Lift the rod out of the location. 2. Pull out the cam to place it in a new location. 3. Lock the rod into cams. For more helpful quick tips on how you can rearrange your closet, visit the The Closet Rehab Youtube channel here .
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. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
