APT specifies and designs the entire circuit around the mill, to
The 1st ever built rod mill 2 m in diameter by 4 m long was to be installed at a mine where a coarser feed was required for shaking tables. Crushing rolls and rod mills were eventually used commonly to prepare feed to shaking tables. Later, rod mills of 2.9 m in diameter by 3.9 m long replaced most roll crushers. Rod Mills cannot be to short With the increase in the diameter of rod mills, problems occurred in the shorter rod mills
May 31, 2016 Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2 feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

Abstract The rod mill product is characterized by its narrow size distribution if it is compared with that of a ball mill operating under the same conditions in open circuit. This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes the grinding kinetics aspect, and partly due to the nature of material flow through the mill with its rod load the ...
Rod Mills ZJH minerals could produce the rod mills of the diameter under 8m. It is featured with high crushing ratio, good reliability, strong adaptability and large capacity.They are applied for the primary ore grinding for the mining industry or the high standard sand making for the aggregate industry.
Rod mills are very similar to ball mills, except they use long rods for grinding media. 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.

Apr 09, 2015 Rod mills This type of mill is only suited for those kinds of ores which are of a fairly coarse nature but once they are broken, disintegrate readily into small size. Typically this type of mill can deliver a product with a fineness of less than 0.1 mm. Testing of material is needed before hand to determine the suitability of the ore for ...
SAG and AG Mills operate by lifting oregrinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill.
Jan 01, 2016 Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill Australia wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.
