Oct 28, 2021 Bond Ball Rod Mill Work Index. Bond ball mill work index (BBMWI) test is a standard test used to measure the ball mill work, which is calculated in accordance with the procedure proposed by the Bond [21]. The BBMWI determines how much energy is needed to grind a sample of ore in a ball mill [22].

Safety is a prime consideration for all Alsto equipment and the Bond Index Ball Mill is supplied equipped with acoustic enclosure. The ball mill is designed to accept a ball charge in accordance with F. C Bond’s standard. This ball charge consists of 286 balls as follows 44 x 35mm balls. 67 x 30mm balls. 10 x 25.4mm balls, 71 x 19.05mm balls.

For practical calculations using 80 passing the 100 micron mesh, the Bond Ball Mill Work Index (BBMWi) is widely used to measure the grindability of a mineral, described in kilowatt hours per ton ASTM C989-989M, Standard Specification for Slag Cement for Use in Concrete and Mortars Siddique, Rafat, and Paulo Cachim.

Bond (1961) and Bond (1963) described a standard procedure to determine work index at length. Pongprasert et al. (1994) followed the procedure step by step using a lab ball mill to determine the Bond work index of feldspar ore from Nopphitam District, Thasala, Nakhon Si Thammarat, Thai-land.

Metso Outotec has designed, manufactured and installed over 8,000 ball and pebble mills all over the world for a wide range of applications. Some of those applications are grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high temperature milling oprations and . All equipment adheres to the applicable.

The grindability test (ASTM D409, ISO 5074) uses a ball-and-ring type of mill in which a sample of closely sized coal is ground for a specified number (usually, 60) of revolutions. Then the ground product is sieved and the grindability index is calculated from the amount of undersize produced using a calibration chart.

Were conducted standard Bond tests to determine ore grindability and work indices, batch grinding tests to determine parameters for breakage and selection functions , and standard ball mill tests for mineral liberation characterization by an automated mineral liberation analyzer (MLA).The tests were conducted in a size range from 0.063 to 2 mm.

An average work index of 15.5 kWh t. A very broad range of results was received, characterising the ‘standard ore’ from medium to very hard. A disappointing result considering the reliance on this test globally for design and optimisation. An improved method using less mass compared to the Bond Ball Mill Work Index test.
