The average particle is subjected to an action similar to many sets of rolls in series, before it is discharged. Because of this, the rod mill can effectively reduce 1 feed size to 10 mesh or finer in open circuit. The voids or interstitial space within a rod load are approximately half those in a ball mill grinding load.

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 5

These mills may be divided into three types ROD MILLS, BALL MILLS and AUTOGENOUS MILLS. In the first type, the ROD MILL, the ore is introduced into the mill. Before we get to the operating skills and theories needed to operate this machine lets go over the construction of it.
Learn how a ball mill works, all of its main parts and some of its design features This 3D animated video allows you to see all the internal parts of a ball mill and what is occurring inside the
A ball mill, a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
The rod mill usually uses 50100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 2550mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8 1 the loading capacity of rod is about 35 45 of the effective volume
The rod mill is a grinding machine with steel rod as grinding medium, mainly used for rough grinding operation. It is generally used as wet overflow type and can be used as onestage open grinding

Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However, many customers are confused when they choosing equipments for grinding due to their similar appearance. This paragraph is a brief explanation to the difference of ball mill and rod mill below.
Rod mill products are generally coarser than those produced in a ball mill. Because of these characteristics, the rod mill has also found wide acceptance by manufacturers of fine concrete aggregates, where rigid state or federal specifications must be met. Rod mills are also used extensively in the grinding of chemicals, coke, limestone, slag, etc.
BallRod Mills, based on 4 liners and capacity varying as 2.6 power of mill diameter, on the 5 size give 20 per cent increased capacity on the 4 size, 25 per cent and on the 3 size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel Head BallRod Mill, as this unit can carry a greater

Rod Mill Introduction The Hongxing Rod Mill manufacturer adopts advanced controllable feeding and discharging technology, combined with the actual grinding material, with the appropriate grinding body, and the traditional surface contact is changed into line contact so that the discharge granularity is more uniform and the output is higher.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Rod mill to ball mill can be done, it is the other way that is difficult. The biggest issue will probably be your ball storage and feed system. This is very different from a rod feed system. Also balls are fed on a fairly regular basis such as once a day.
Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semiautogenous mills having between 100 and 1,000
