The work indices of various iron ores in the world were measured. From the values of the work indices of the iron ores, the powers required to grind the iron ores were estimated. And thus, the grindability of the iron ores was investigated. The results obtained are as follows: (1) The work indices of the iron ores are ranged from 6.22 to 17.40.
Sag mill and ratio of bond ball and rod work index. 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).

Mar 10, 2020 Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps ...
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 m.

Ball mills usually operate at 65% to 75% of the critical speed. The critical speed is calculated as under . R r g 2 1 n c (2) 2.1.3 Work Index: Work index is defined as the gross energy required in kilowatt-hours per ton of feed needed to reduce a very large feed to such a size that 80% of the undersize passes through 100- m screen .
The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis to another. The proposed model consists of two components, the variable coefficient that is determined from a specific work index determination and a fixed exponent determined by a calibration procedure.
Ball Mill for Iron ore benefication: A Ball Mill a type of grinder is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball Mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
