Ball Mill vs Rod Mill | How To Choose Ball Mill or Rod ...

30.12.2019· Generally, users can choose ball mill or rod mill on base of their raw materials, product size and properties of the equipments. 1. According to Ore Properties. To a great extent, the hardness and granularity of ore will affect the selection of grinding equipment. Some ores with dense structure, small crystal and high hardness are difficult to grind. Therefore, a longer …

Rod Mill - an overview | ScienceDirect Topics

Rod Mill. Rod mills are charged initially with a selection of rods of assorted diameters, the proportion of each size being calculated to approximate to a seasoned or equilibrium charge. From: Wills' Mineral Processing Technology (Eighth Edition), 2016. Related terms: Ball Mills; Mechanical Alloying; Amorphous Phase

Rod Mills - Mineral Processing & Metallurgy

31.05.2016· 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.

05.04.2018· When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only. If the rod mill feed will consistently be the same size, such as produced with closed circuit crushing, do not apply a rod mill …

Rod Mill Introduction,Rod Mill Working Principle

Rod Mill Introduction. Rod mills are very similar to ball mills, except they use long rods for grinding media. Rod mill is named like this because the grinding media filled in the cylinder are steel rod. The rods grind the material by tumbling within the 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 …

Rod mills, how they function - Mine Engineer.Com

Of the three main types of rod mill, overflow, end peripheral discharge, and center peripheral discharge only the overflow mill is in common usage. Wet grinding rod mills are normally used in the mineral processing industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill …
