Rod mill is also called rod grinding mill. Grinding rod mill can be classified into ore rod mill, wet rod mill and so on. Grinding rod mill is mainly used in the preparation of the coal chemical industry, quartz sand, silica sand, sand filling, tungsten ore, potassium and sodium feldspar, bauxite and other industries. The particle size of the finished products produced by the rod mill is
The characteristic of the rod Mill is that in the grinding process, the grinding medium is in line contact with the ore, so it has a certain selective grinding effect. Product particle size is more uniform, less crushing ore grains. When used in coarse grinding, the processing capacity of the rod mill is larger than that of the ball mill. Advantage. save power Save more than 40% of the power

(1) Rod mill is usually selected in order to prevent over grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine; (2) In two stages grinding, the capacity of rod mill machine used in the first stage grinding is larger than ball mill''s; (3) In some cases, rod mill can replace short head cone crusher.
The general ore grinding process in most overseas ore beneficiation plants is made up of crusher, rod mill and ball mill. The rod mill is hardly used in China ore beneficiation plant. The feeding particle of ball mill is too high, which causes the large consumption of energy, grinding medium and lining plate. In addition, the grinding efficiency is relatively higher, product granularity is
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 lower steel consumption. Our heavy rigid construction combined with the open end feature insures maximum
The rod mill feeds a wet ball mill at a feed size of mm (1000 μm) and produces a product with 80% passing a 150 μm screen. The rod mill is in an open grinding circuit. Determine: 1. the shaft power of the rod mill, 2. the size of the industrial mill. Data: Laboratory Standard Bond Test: Rod Mill: Grindability index at 10 mesh = kWh/t
Figure Media motion in the tumbling mill. Grinding Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semiautogenous. The grinding action is induced by relative motion between the

Ball mills can be used for coarse grinding as described for the rod mill. They will, however, in that application produce more fines and tramp oversize and will in any case necessitate installation of effective classification. If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25
Rod mills are very similar to ball mills but instead of using grinding balls they use long steel rods to do the media grinding. Some miners believe that rod mills are more efficient than ball mills and that the desired product result is obtained at a lower cost per ton. But it depends on the material you are mining for that will ultimately decide whether you should use a ball mill or a rod
Product Process. Raw material: high quality round steel; Forming: cutting; Quenching: quenchant ; Tempering: continuous tempering furnace; The quenching and tempering heat treatment wearresistant steel bar is produced by automatic production method, which is suitable for the use of rod mill. According to different materials and hardness, the performance is different. The key is the

While most grinding in the mineral industry is achieved using devices containing a steel grinding medium, the IsaMill uses inert grinding media such as silica sand, waste smelter slag or ceramic balls. The use of steel grinding media can cause problems in the subsequent flotation processes that are used to separate the various minerals in an ore, because the iron from the grinding medium can
Grinding machine is the key equipment for grinding materials after the crushing process. But do you know what factors should be considered when choosing grinding machine? Click it to learn more details. 05:02:00 . 424. 0. How Does Raymond Mill Work? Raymond mill is a commonly used equipment for processing nonmetallic mineral grinding powder. Do you know how does it work?
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. The rods used in the mill
23/12/2013· Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a selfgrinding mill which is used in breakage of larger rocks. SAG (SemiAutogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length. Vertical mill is used in grinding material at smaller particle sizes, which is used
In addition, the processing capacity of the rod mill is larger than that of the ball mill of the same specification. The overflow, end peripheral discharge and center peripheral discharge are the three main types of rod mill, while only the wet overflow type rod mill is usually used as the pregrinding equipment in the cement plant. In order to
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.
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. . Rod mills are less common than ball mills for grinding minerals. The rods used in Quartz or silica is commonly used because it is
Grind coarse feed material with a reliable Rod Mill that won''t overgrind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions like Rod Mills. Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product.
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 to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of
