Siemens, the company that introduced Gearless Mill Drives (GMD) to mining industry started up its first GMD on a ball mill in Norway in 1980. The mill and its drive system are still in service. Today, GMDs are mainly used for SAG mills between 36 and 40 feet (10.7 to 12.2 m) and ball mills from 24 to 28 feet (7.3 to 8.5 m).

Laboratory Ball Mill Tests were conducted with all four ores to determine the effect of CaS addi tion on mercury, silver, and gold during grinding. A 50-pct-solids slurry con taining 1 lb st NaCN, enough lime to give a pH of 11, and 0.1 lb st CaS 4 was added to a laboratory ball mill and ground for r.

Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33 Dry Ball Mill = kg kWh = 0.023A i 0.5 Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size. Azzaroni (1981) and Dunn (1989) recommended the use of the following expression for the size of the makeup media.

From one side. As the mill rotates at low speed the grinding media is ground into very fine particles due to the action of balls or rods on the grinding media. The ground products can be collected on other end. Figure 1.1 [1] shows the cut away section of a ball mill. Figure 1.2 [1] shows an industrial ball mill. The two types of tumbling mills.

0.23 S. The ore is a combination of competent diorite and andesite, with typical ball mill work indices of 14 to 17 kWh t, rod mill work indices of 21 to 26 kWh t and unconfined compressive strengths of 150 to 200 MPa. Production of gold from oxide ores at BGM began in August 1987 and is.

Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many.
