Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..

The Strommashina plant manufactures a wide range of the rod …
This test determines the Bond Rod Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements of sizing rod mills. The test is a closed-circuit, dry grindability test, is run in a standard rod mill, and can be performed at sizes ranging from 4.76 mm to 210 microns.
The ball mill oversize feed factor (EF 4 BM) is always calculated with the rod mill work index for the optimum feed size and the ball mill work index for EF 4 BM. The model assumes that the calculated value of E ssbm + the specified contingency is greater than the sum of E sag + E peb ; otherwise E bm will be negative.

In addition, with same specificationthe, the cylinder rotating speed of the rod mill is lower than that of the ball mill. The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium.
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. Though ball mills are used more often rod mills can be the better option for specific mining ores and larger site projects. In a ball mill the actual balls in ...
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. 2. Selection by required particle size
Ball Mills vs Rod Mills - Metallurgist & Mineral Processing Engineer
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.
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 nes present being fi fi ner than 650 μm.
was surprising that the Bond Rod Mill Wi average was 11.3 kWh/t. Since the ore is unusually soft, the Rod Mill Wi is probably irrelevant in determining required power for the SAG mill.
