Ball mills are used extensively for grinding metal bearing ores and abrasive minerals. ... A wet grinding 4 x 10 center peripheral discharge rod mill used for producing fine aggregates. ...
2012-11-26The 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.
2020-5-1F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. citation needed But note that the term rod mill is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...

The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. ... A cone crusher consists of an interior grinding cone that rotates on an eccentric vertical axis inside a fixed outer cone. ... in diameter. The mixture of ore and water is further broken up in two ball mills, which are like a rod mill ...
2019-6-28SAG Mills are advantageous because they utilize the ore material as a grinding media, thus the actual grinding media costs are reduced. The balls in the mill serve to increase the amount of grinding done compared to if the mill was fully autogenous.
2015-7-17maximum size of 3 to 15 mm in diameter. This crushed ore was then taken to rod or ball mills for grinding to the size required for flotation. From grinding mills, the pulp was fed to classifiers e.g. Cyclones, which returned the coarser particles to the mill for further grinding. According to 9, fineness of
The objective of this study was to conduct a rapid determination of Bond work index by considering grinding kinetics of the particles in standard Bond rod-mill as well as size-mass balance equations in the mill. For this, series of experiments were conducted on different ore types to simulate grinding kinetic in a rod-mill.
