JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016 374 Performance Rod mills are used in an open circuit between crushing and the ball mill They often operate in wet and where the pulp contains up to 50% solid by mass This machine is equally very applicable to dry …

When calculating rod mill power for a rod-milling-only application, use an inefficiency factor of 1.4 when the feed is to be prepared with open circuit crushing, and use 1.2 when the feed, is to be prepared with closed circuit crushing. The other milling efficiency factors also must be applied to the calculated- grinding power.

Typical mill circuit on Vimeo. F 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 ...

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. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.

Rod Mill an overview ScienceDirect Topics. Rod mills are used in an open circuit between crushing and the ball mill They often operate in wet and where the pulp contains up to 50% solid by mass This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture As such, when the product is sticky, rod mills are preferred over ball mills

Is A Rod Mill An Open Circuit. Rod Mill Design Calculations EF1 Dry Grinding for the same range of work dry grinding requires 1 3 times as much power as wet grinding EF2 Open Circuit Grinding when grinding in open circuit ball mills the amount of extra power required compared to closed circuit ball milling is a function of the degree of control required on the product …

The Rod line maximum capacity is 264,000 short tons per year. Molten copper is molded into a bar at a rate less than ½ a mile per hour and exits the mill close to 72 miles per hour. The bar is rolled through 16 stands and is reduced from a 2.5" x 5" rectangle bar to a 5/16" rod (1/200th of its original size).

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
