### How to Charge Rods into a Rod Mill - The Charging Process ...

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.

### Grinding Balls & Rods

As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%. It has been found that as grinding rods wear a 4″ or 4½” rod will generally break up at about 1½” diameter.

### Recommended Rod Mill Bar Length

The mill length inside end liners measured along the surface of the shell liners should be 0.1 to 0.15 meters (4″ to 6“) longer than the rods so that the rods will fit in the length of the grinding chamber without tipping or laying across the charge.

### Rod mills, how they function - Mine Engineer.Com

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 they can cause rod tangling.

### Ball Mills vs Rod Mills

Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in …

### Tubular Rod Mills - ScienceDirect

8.3. Operation of Rod Mills 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 …

### Rod Mills | rod mill grinding, rod mill crusher| Korea Crusher

Rod mill Grinding are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum, in place of steel balls in ball mills. Rod mills are an efficient crushing machine for grinding various materials into powder.

### Rod milling in the Magotteaux Mill - Grinding Solutions Ltd

Grinding Solutions are currently running extensive flotation trials on a base metal project, where the Magotteaux Mill is running a rod charge rather than a ball charge. This is done in order to better simulate the particle size distribution of a ball mill in closed circuit …

### Rods Mill For Grinding - rolvaplast.be

Mill (grinding) - Wikipedia. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.

The rods grind the ore by tumbling within the the 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).
