Rod Mill

Rod Mill Introduction:

Rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and construction

materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making.

Our high-efficiency rod mill adopts rolling bearing support instead of sliding bearing support with

bearing bush. Therefore, it has advantages of even discharging size and high capacity

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 mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod

charge tangling.. Grinding action is by line contact between the rods extending the length of the mill. Rods

tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential

grinding of coarse material and minimizes production of slimes.

Of the three main types of rod mill, overflow, end peripheral discharge, and center peripheral discharge only

the overflow mill is in common usage. Wet grinding rod mills are normally used in the mineral processing

industry. Dry grinding is used in some areas; however, it is confronted with problems and should be avoided

except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled

and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower

speed and better contact between the media and ore. The rod charge must be maintained in good working

condition, and broken and worn rods must be removed. Rod mills usually require greater operator attention. It

is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action

is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in

turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners

result in greater wear on the mill liners.

Rod Mill Application and Working Principle:

Rod mill has dry and wet two sorts to decide on, Users shall make choice with regards to the actual

Requirement. The company uses the advanced output controllable technology, with the face milling

Material set the best miller, affect the traditional surface contact into line contact, increase the risk for

output granularity evener, high product, widely used in chemical industry, metallurgy, glassed Industry,

as well as the high fineness element milling industry milling, sand making of building rod mill working

principle Rod milling type system pressure-blasting machine by motor through reducer and

peripheral big gear transmission or by low-speed synchronous motor directly with the surrounding

big gear transmission, drive barrel rotary.

Rod Mill appplied to metal and nonmetal imne, water conservancy and glass building materials for

grinding various ore, rock. The grinding medium in centrifugal force and friction force, under the

action of was promoted with a certain height, fall or discharge is thrown down state falling.

By grinding materials by providing ore mouth continuous in to the cylinder, be movement with the

internal grinding medium crushing, and through the overflow and continuous provides ore power of

merchandise, from the cake layer

Rod  Mill Features

1.It is an efficient tool for grinding many materials into fine powder.

2.Popular in building material, and chemical industry.

3.Can be utilized both dry and wet.

4.Because the barrel rotates, the material is crushed involving the individual pieces of grinding  

    media that mix and crush the merchandise into fine powder over a period of hrs.

5.The longer the mill runs, the finer the powder will probably be.

6.Our rod mill is widely applied in metal and nonmetal mine, water conservancy, glass and

   construction materials industries, mainly suitable for grinding various ores and rocks and artificial

   sand-making
