SmallScale Tests to Characterise Ore Grindibility

to that of the ball mill test, as follows: It is common to observe a difference between the rod mill and ball mill values for a given ore type. These differences may be caused by a variation in ore hardness by size ( for RWI and for BWI), and/or grain size properties. The Bond rod mill work index is used

Abstract. Size reduction is one of the most common unit operations for both active pharmaceutical ingredient (API) and drug product resulting particle size distribution (PSD), in most cases, is believed to have great impact on bioavailability and/or downstream processes. However, the fundamental understanding of the process is still limited.

Numerically, the work index is the energy required in kwh/t to reduce a given material from theoretically infinite feed size to 80% passing 100 microns. The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test. Bond developed separate tests for the rod mill and the ball mill.

· Abstract. At the Sarcheshmeh copper mine, 41 000 t ore per day with an average grade of 0·9%Cu is ground to 70% passing 75 μm. Grinding is effected in eight parallel lines of 8 × 5 m ball mills in a closed circuit with cyclones. The makeup balls are 80 mm forged alloy steel balls and the average ball consumption is 750 g t −1 ore ground.
