A secondary mill will require the high surface contact with more of the grinding motion that the lower cascade brings. This means that the secondary mill will have LOW PROFILE ROD MILL LINERS in them. If it is a ball mill being used as the primary grind the size of the grinding media will be increased, this is to increase their impact.

Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles present between each rod, while no fine particles receive impact and are ground.

Mill finish is the surface texture or finish of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre it may have spots of oxidation or contamination with mill oil.
Common examples are rod and ball mills, both of which are of the rotary drum type which rely on internal grinding agents to achieve their milling action. Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods lying within the drum and parallel to its axis.
The recent price hike of rod does not for syndicate, rather it is an impact of raw materials price hike in the global markets, claimed leaders of different rod mill owners39 associations.
Rod life is maximized of rod lengthtomill diameter is maintained between 1.4 to 1.6. Rods wear unequally with thin rod formed at the feed end and forming an elliptical shape. Rod diameter is a function of
citation needed But note that the term 39rod mill39 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. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter.
End Peripheral discharge and center peripheral discharge rod mills are described in detail on pages 28 and 29. Feed and discharge heads of Rod Mills are conical in shape providing important advantages over a mill with straight heads. 1. They provide the essential feed pocket and also a space for the pulp to squeeze from the rod mass.
Rod Mill Work Index Table Previous Next Here is a list presented in table form of Rod Mill Work Index as testedpresented by SME handbook of mineral processing, N.L Weiss Editor, N.Y. 1985.
Rod Mill. 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. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
Commentary on the apparatus of the Bond rod mill Work Index. by Alex Doll December, 2015. The Bond Third Theory of comminution was originally divided into three size classes reflecting the varieties of comminution equipment common during the time period when Bond and his collaborators were gathering the information to calibrate comminution models.
The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill models expect a mill with a 34wave liner34, and is not compatible with mills using 34smooth liners34.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.
