grinding mills. Our rod mills have been manu-factured since 1925. Applications The rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/ coke, and other materials for both wet and dry p- a plications. The rod mill accepts feed ore as coarse as 1 1/2" top size although better performance is obtained
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 place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ...
The article presents the results of laboratory-scale research on the determination of the impact of ball mill parameters and the feed directed to grinding on its effectiveness and comparing it with the efficiency of grinding in a rod mill. The research was carried out for grinding copper ore processed in O/ZWR KGHM PM S.A.

The principle of Grate Discharge grinding is nearly universally adapted in the cement grinding industry. Grate Discharge Ball Mills are the rule rather than the exception. Rod Mills for raw and finish grinding begin to enter the picture. Larger and larger diameter mills become common. Lengths tend to shorten. Cement grinding …
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.
3. Peripheral Discharge Rod Mill. This type of rod mill is similar to the overflow type, but the discharge end is fitted with peripheral discharge plates that allow coarse particles to exit the mill quickly, thus preventing over-grinding and minimizing production of fines. 4. Center Peripheral Discharge Rod Mill. In this type of rod mill, the ...
Essa RM Series Laboratory Rod Mills are recognised for their efficiency, uniform granularity and high quality sample achieved when milling and grinding.

Over a range of mill speeds (about 40 – 60 of mill critical speed for rod mills and 50 – 70 : of mill critical speed for ball mills), the holdup is approximately constant but at rotational speeds above or below this range, the holdup increases sharply.
The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary portion of a grinding circuit will utilize the lower profile liners. The reason is as lift decreases, friction ...
