Ball Mill Vs Rod Mill How To Choose Ball Mill Or Rod

the overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. but the both are different in performance and applications. In this article, the similarities and differences between ball mills and rod mills are analyzed from aspects, and suggest how to choose ball mill or rod millplanetary ball mills have been proven their applicability as reactors for organic syntheses from different points of view. performance of chemical reactions in the solid state without a solvent takes advantage of the high mixing efficiency of ball mills and the continuous particle refinement resulting in sep 01, 1991 scanmec designs traditional mills of all sizes from 100 to 4,000 kw, but for large mills it prefers the shell-supported design, with or without a wrap-around motor. the first installation of this type, built in conjunction with aker trondelag as, was the sydvarager ball mill, diameter by long, powered by an 8.1 MW siemens wrap grinding media in coarse-grinding chambers, i.e. balls of up to 100 mm in cement mills and balls of up to 100 mm in dry-process raw mills. the ducrostep shell lining is a fully bolted on lining except for

Ball Mill Shells From South Africa To Egypt

design and construction of prestigious gold mining projects. the challenge our client was contracted to manage all aspects of a major gold mine upgrade in egypt, including engineering, procurement, construction and logistics. the upgrade included enhancement of onsite crushing capabilities requiring the importation of large ball millsabstract: processing in planetary ball mills is well suited to a large number of applications because they are easy to operate and versatile, grinding faster than other mills. research related to planetary mills are mainly about the process evaluation, and there are few studies on the mechanical design aug 01, 2007 sag mill liner development draws primarily on practical experience from sag milling operations supported by computer-based modeling of charge motion in sag mills and on established good design practice. liner design needs to respond to the process aspects of mill liner action that are critical to good sag mill performance, i.e the impact of shell liners on the grinding action and of 8.3.2.2 ball mills. the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter the feed can be dry, with less than moisture to minimize ball coating, or slurry containing 2040% water by weight.
