The overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. But the both are different in performance and applications. In this article, the similarities and differences between ball mills and rod mills are analyzed from 9 aspects, and suggest how to choose ball mill or rod mill.
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 most of their crushing force on the
Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals.
Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
Nov 19, 2019 The rod mill adopts overflow type and open type discharge, does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state.
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.
Grind coarse feed material with a reliable Rod Mill that won't over-grind. 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 ball mill for mineral processing. It accounts for up to of the total power consumption in mineral processing plant operations so, selecting the efficient solution for grinding section is very important prominer provides ball mill rod mill grinding system which is widely used in various types of ores beneficiation, electricity, cement and chemical industries

Nov 19, 2019 The rod mill adopts overflow type and open type discharge, does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill
The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3. Mill length = 7 meters. Rod Mill-Ball Mill Circuits Diagrams of mill circuits [image: (135-8-2)]
Sepor’s 16 x 32 continuous ball or rod mill is ideal for pilot plant studies of ore grinding and processing or just regular small scale grinding requirements you may have. The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill.
Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. The daily maintenance requires constant addition of a certain amount of steel balls, while the rod mill only needs to be inspected and replaced in a period of time.The product of the rod mill is rough, but the particle size is uniform, coarse particles and slime are less, the over
Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency, better grinding performance and lower energy costs.
Jun 11, 2019 The ball and rod mills are similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium. In some cases, they can be used interchangable, but not with a mix of balls and rods. Both ball and rod mills can be operated either wet or dry, and in a batch or a continuiously mode.
What s the Difference Between Ball Mills and Rod Mills . The rod mill adopts overflow type and open type discharge, does not use grate type discharge the diameter of the rod mill discharge end is larger than that of the same size ball mill when the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state
No 1 rod mill/ball mill circuit was operating very effi ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than 0.5 due to an extra amount of
mills. The mills in mining operation grind the product from the crushers to fine material ready for treatment. Rod mills, ball mills, autogenous mills, and semi-autogenous mills (SAG Mills) all have a number of lubricating and hydraulic systems, and they must work to keep mineral output high.
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
The over-grinding phenomenon of the grinding process is severe, and the grinding efficiency is also significantly lower; however, the overflow ball mill has a simple structure, is inexpensive, and is suitable for fine Grinding equipment, so overflow ball mills are also widely used in production practice. Rod mill
Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. However there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency, better grinding performance and lower energy costs.
Category analysis (different drainage methods)In the ball mill, there are commonly used lattice type ball mills and overflow type ball mills (named from different mine discharge structure), while rod mills do not use grid plate for mine discharge, only overflow type and open type, and the discharge end The diameter of the hollow shaft is

They 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 done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency through automatic operation
