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 .
Jan 01 2013 To calculate Bond rod-mill work indices the four samples were screened and the particle size distributions plotted in Fig. 2.The plot was used to find F 80 of the samples for calculations. Fig. 3 Fig. 4 show the grinding kinetics of Pb Cu Fe and Mn ores in the Bond rod-mill in different test-sieves. The slopes of all lines in the figures are equal to the k value of Eq.
Bond Work Index - an overview - ScienceDirect Topics. The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 336 mm 6 mesh to product size in the range of 45-150 m 325-100 mesh thus determining the ball mill work index Wi B or BWi The work index calculations across a narrow size range are conducted using the appropriate laboratory work.
Rod mill power is dependent on mill capacity and work index. Mill power increases with Increasing rod charge Increasing mill speed Increasing mill length. Rowland and Kjos 1980 provided an expression to quantify power draw at the pinion shaft per unit mass of rods P M

Dec 01 2007 The traditional Bond work index proposed by F.C. Bond over 60 years ago is still today a useful tool for characterizing material crushability and grindability in the minerals industry. Although not as popular as the Bond ball mill or the Bond rod mill work indices the impact work index also called Bond crushability index continues to be much .
The Bond Work Index for Rod Mill is a special equipment for testing Bond rod mill work index. Simple lab test can choose rod mill by power method or judge the effects of material properties change to the rod milling process or the operation condition of rod mill by using this equipment. From 1980s the company developed the equipment and .
Generally Bond work index is a common method for selecting comminution equipment as well as estimation of grinding efficiency and calculating required power. In the current research a simple fast and accurate procedure is introduced to find the rod-mill work index based on the conventional Bond work index.
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.

The design of rod and ball mills is still carried out with the Bond ball mill and rod mill grindability tests. As discussed earlier in this paper it is important in this case to match the reduction size of the test to that desired from the industrial mill. As such primary ball mills should be designed with the rod mill work index and single .
