advantage of rod mill over ball mill

  • Ball Mills vs Rod Mills

    Ball Mills vs Rod Mills. Previous Next 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

  • Rod Mill an overview ScienceDirect Topics

    As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small

  • Rod Mills Mineral Processing & Metallurgy

    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. This internal feed pocket permits coarser pieces of material to roll down to the toe of the rod load and be absorbed, minimizing rod spread. Rods will not tangle or jam

  • Ball Mill: Operating principles, components, Uses

    A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed

  • Ball Mills Mineral Processing & Metallurgy

    Over a period of many years various fine grinding machines have been developed and used, but the ball mill has become standard because the Steel-Head Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness. In larger plants where several stages of coarse and fine crushing are used, it is customary to crush from 1/2″ to as fine as 8 mesh. Many grinding circuits

  • Grinding Mills: Ball Mill & Rod Mill Design & Parts

    Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding

  • Advantages of Bead Mill and Ball Mill zhangchun002

    As to the production of the two grinders, it is very easy for us to find the advantages of the bead mill. Usually, the bead mill can produce great amount of powders while the ball mill can only produce a little good powders. As to the noise, the ball mill has larger noise than the bead mill. However, the ball grinder also has its advantages

  • 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. Rod mills accept feed up to about 50 mm

  • Rod mill should be chosen over ball mill gooブログはじ

    Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. The calling name of ball mill and rod mill is from the different grinding medium. The ball mill&&'s grinding medium is steel balls, which is a kind of high-strength wear-resisting material. The grinding medium of rod mill is steel rods. However there are some advantages to using rod

  • Comparison between Rod Mill and Ball Mill ore

    Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing. 2. In the two stage grinding process, if it requires grinding the ore from 20-6mm to 1-3mm in the first stage, rod

  • Ball Mills an overview ScienceDirect Topics

    Ball mills have the following advantages: To minimise over-grinding modern ball mills are fitted with dynamic separators (otherwise described as ‘classifiers’ or more simply as ‘separators’). The working principle is that cement is removed from the mill before over-grinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about

  • Mill (grinding) Wikipedia

    A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
