Bond Tests Mining SGS

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.

Rapid determination of Bond rod-mill work index by

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.

A study of simulating the calculation method of the Bond

Based on the nth order grinding kinetic equation and the theory of linear additivity in the grinding process, the grinding kinetic characteristics of the feed and the circulating load in standard Bond rod-mill grindability tests are studied.A new method of simulating the calculation of the Bond rod-mill work index by using the grinding kinetic test data of the feed is proposed.

Relationships between comminution J energy and product

Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond’s theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond’s equation is as follows: [6] where W is the work input (kWh/t); Wi is the work index

Bond Ball Mill Index Test JKTech

A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample Requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.
