Ball Mills vs Rod Mills

These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. Rod Mills = Selective Grinding Ball Mills = Non-Selective GrindingHow HPGRs compare to conventional milling,Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to beGrinding Machines: Types and Selection Principles,The processing capacity of ball mills and rod mills is usually calculated by volumetric method or power consumption method, and the selection of ore mill should meet the following requirements: 1) Rod mills are mostly used for rough grinding, with a discharge particle size of 1~3mm, which can be ground to 0.5mm in a gravity separation plant.

What are the differences between ball mill and rod mill,

14/11/2019· Grinding medium of rod mill The rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while filling rate of ball mill is 40% to 50%. Rod is mainly made of several materials: A High carbon steelBall Mills - Mineral Processing & Metallurgy,11/10/2016· For the same reason the ore must be friable ; rods cannot compete with balls in grinding hard or tough material. Since the surface area of a load of rods is much less than that of a load of balls occupying the same space, the ore is not ground so fine in a rod mill as it would be in a ball mill of the same size.Ball Mill vs Rod Mill | How To Choose Ball Mill or Rod,,The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium.

The Difference Between the Ball Mill and Rod Mill Essay,

Rod mills are very similar to ball mills, except they use long rods for grinding media. The 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.Ball Mill VS Rod Mill-xinhai,For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. But for rod mill, grinding effect is better which need a lower rotate speed and has a lower power consumption. Xinhai produce,Mill (grinding) - Wikipedia,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.

How HPGRs compare to conventional milling

Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis.Key considerations when selecting a mill lining system,There are numerous types of mill designs including autogenous, semi-autogenous, ball, rod and scrubber mills. This guide will refer to the two most common varieties: Semi-autogenous (SAG) and ball mills. Key considerations. Numerous factors must be considered when selecting a mill liner design, including required grinding action, mill size as well as ore and grinding media characteristics,Rod mills, how they function - Mine Engineer.Com,Rod mills are very similar to ball mills, except they use long rods for grinding media. The 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.
