Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closed-circuit dry grindability test performed in a standard rod mill.

The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus.The SAGMILLING.COM models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners".

Rapid determination of Bond rod-mill work index by modeling the grinding kinetics. ... The Bond rod-mill work index is used in conjunction with Bond’s third theory of comminution to merely calculate net energy requirements for sizing rod-mills. This test was originally developed in the mid 1930s by F.C. Bond. ... To calculate Bond rod-mill ...

using Bond rod mill work index (RMWI), and Bond ball mill work index (BMWI). However, the author has developed a relationship between the Bond third theory SE values and the AG/SAG SE values to enable the additional power required for AG/SAG milling to be determined.

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

W is the work index measured in a laboratory ball mill (kilowatt-hours per metric or short ton) P 80 is the mill circuit product size in micrometers; F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles.

The Titan Bond Work Index Rod Mill is one-piece cast construction with integral wave liners of a form described by Bond. This mill is used to perform the necessary metallurgical testing to determine the grinding characteristics of ores and power requirements for operating production-size rod mills.

At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm.

The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a “single-stage ball mill” calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies below 75 µm ...

Index (BWi), the Rod Mill Work Index (RWi), the Crusher Work Index (CWi) and the Abrasion Index (Ai). Over the years, it has been determined that Efficiency Factors (EF1 to EF9) should be applied to Equation 1 to drive the corrected power requirement (Rowland, 1982).
