The rod mill usually adopts the steel bar with a diameter of 50-100mm as the grinding medium, while the ball mill often uses steel ball as the grinding medium. The difference on grinding medium is the main difference between the ball mill and rod mill. There is point-to-point contact between the ball mill with the steel ball, while there is line-to-line between the rod mill and steel rod. So ...
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 ...
The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 25-50mm 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 of rod mill.
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.
the Difference of Rod Mill and Ball Mill. Rod mill , as the name suggests, is to rely on rod bars for the material grinding,and wet overflow is a generally used material wayRod mill is generally used as a grinding equipment in the artificial stone sand, concentrator, chemical plants and power sectors the ball mill has a great similarity in appearance with rod mill,which is most
24/04/2020 In 1870, on the basis of ball mill, rod mill with uniform discharge size was developed. In 1908, a self-grinding machine without grinding medium was created. From the 1930s to the 1950s, the United States and Germany successively developed roller bowl mills, roller disc mills and other vertical shaft medium speed mills. The appearance of these crushing machines has greatly improved the ...
Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product. Our Rod Mills are available in multiple diameters to fit the needs of your operation.

Once replaced by AG and SAG mills, Rod Mills have had a recent ...
The structure of the rod mill is roughly the same as that of the overflow ball mill. The grinding medium is round. The structure should be slightly different from the ball mill in order to ensure that the rod is flexed without hitting each other when there is a regular movement and falling in the rod mill. The cone shape end cap curvature of the rod mill is smaller, the inner side is lined ...
Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing. 2. In the two stage grinding process, if it requires grinding the ore from 20-6mm to 1-3mm in the first stage, rod ...
19/11/2019 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.
The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30% higher than the energy consumed by bar mills and this is for comparable performance.
