20191213Bond Ball Mill Index Test. Measuring ore grindability in balls mills. The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a locked cycle test conducted in

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.

The Bond Ball Mill Grindability test is designed to give a measure of the grinding characteristics of a material by finding the amount of size reduction resulting from a controlled energy input. Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured.

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling.

examined the relationship between them. The most widely known measure of grindability is Bond's work index which is defined as the resistance of the material to grinding. The standard equation used by them for the ball mill work index (Bond work index) is as follows. / F 80 80 0.23 0.82 /10 44.5 1.1 GP W i bg i

In recent years, many grindability test methods have been developed on different scales for different applications, from common mills circuits to autogenous (AG) and semi-autogenous (SAG) mills circuits. The most common grindability tests used in the industry are the Bond ball mill work and Bond rod mill work tests.

The procedures to carry out the Bond grindability tests in ball mills and rod mills. are outlined in Sections 2.2 and 2.3. They are usually referred to as the standard tests,

3.2 The test of standard ball mill Bond grindability The standard Bond grindability test is a closed-cycle dry grinding and screening process, which is carried out until steady state condition is obtained. This test was described as follow (Bond and Maxson, 1943: Yap ct al., 1982; Austin and Brame, 1983; Magdalinovic, 1989):

Determining the Bond work index is a standardized method for characterizing the comminution performance of mineral samples. CEMTEC uses this method for designing rod and ball mills. The comminution performance is, just like the desired comminution step and the production capacity, crucial for determining the required mill size.

GRINDABILITY TESTS BOND BALL MILL GRINDABILITY The Bond ball mill grindability test is performed according to the original Bond procedure [4]. It requires 10kg of minus 6-mesh (3.35mm) material that is preferably prepared at the testing facility, by stagecrushing the sample to passing 6-mesh, but normally less than 5kg are actually used in the

grams per revolution (Gbp) is the ball mill grindability. The ball mill work index, Wi (kWh/short ton) is calculated from the following equation (Bond 1961):1 The mill should be cleaned by either blowing air into it or wiping the interior with a cloth and or brush. The FC Bond ball mill is now ready for the next sample.

Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
