F 80 is the mill circuit feed size in micrometers. 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.
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 machine is characterized in the process of grinding, the grinding medium and the ore is line contact, and thus has a certain role in the selective grinding. The particle size of the product is more uniform, crushing the ore grain less. For coarse grinding, ball mill processing capacity than the same specification of rod mill.
Alibaba offers 303 grinding media rod products. About 57% of these are cast & forged, 24% are ceramics, and 4% are stainless steel bars. A wide variety of grinding media rod options are available to you, such as alumina ceramic, steel, and zirconia ceramic.
Rod Charges. Rod mill charges come in Stainless steel and mild steel only. Grinding Media. Generally, steel grinding balls are used with steel mills, ceramic balls are used with porcelain or ceramic lined mills and steel, ceramic, or other high density media is used with elastomer lined mills. Porcelain balls have a SG of 2.3 and have a average ...
Two sizes of rod mills viz. 7" x 14" & 14" by 28 " are available with recommended quantity of grinding media of assorted sizes. For special applications the rod mills are provided by PolyGate wave type abrasion resistant lining with grinding media specially designed for wet grinding applications.
Once in motion, energy is only needed to move the grinding media as a fluid mass, and to overcome frictional losses. The increased number of impacts in the VIBRA-DRUM® Grinding Mill results in a faster, more efficient grinding action. As the grinding mill vibrates, media particle migration is experienced in both axial and transverse directions.
Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media. This also results in .
Rod Mill. The rod mill is loaded with the grinding media of steel bars. It consists of five parts including cylinder shell, feeding system, discharge system, main bearing and transmission system. It is available for both of the dry grinding and wet grinding fashion as the customer's needs.

Ball/Rod mill Literature . The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
The features of rod mill are that in the ore grinding process, the grinding media contact with the ore in a linear manner, so that it has selective grinding function. The granularity of the final products is even, and the amount of the particles that are over crushed and ground is low.
A ball mill is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media.
Mar 20, 2017· Different Types of Tumbling Mills Rod Mills:-Mills loaded with rods as the grinding media are used for primary grinding of rocks and minerals. The rods fall from a height and roll down the mill so the rods impart an impact force as well as an abrasive action. The product size from a rod mill .
At present, according to different grinding media, grinding equipment can be divided into rod mill, ball mill, gravel mill, self-mill and so on. Ball mill laboratory type Rod Mill, which has a long history and a mature manufacturing technology, is widely used in production practice and laboratory.
In a drum mill the sample (usually pre-crushed material) is placed inside the drum with the grinding media (grinding balls or rods) and subjected to external forces. The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction, in wet or dry condition.
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.
