Ball Mills - Mine Engineer.Com

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge

13/02/2017  Ball Mills. Ball mills can be used for coarse grinding as described for the rod mill. They will, however, in that application produce more fines and tramp oversize and will in any case necessitate installation of effective classification. If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25—40 mm(1″—1½”) balls and possibly tertiary ball mill

22/01/2020  In the original concentrator, material with a copper grade over 0.38% is loaded onto trucks and sent to the milling circuit, where giant rotating crushers reduce the size of the ore to approximately onehalf of an inch. The ore is then sent to the ball mills, which grind it to the consistency of fine powder. The finely ground powder is agitated in a water and reagents solution and is then transported to flotation cells. Air is pumped into the cells producing a froth, which carries the copper ...

TECHNICAL NOTES 8 GRINDING R. P. King

These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines ...

Mill (grinding) - Wikipedia

Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral ...
