201784 The laboratory ball mill was designed for grinding limestone, meaning that the work index required for the specific power calculation was assumed to be the work index of limestone, which is 11.6 KWht, with a specific gravity of 2.6 gcm. 3. or 2600 kgm. 3. The feed size F. 80 of the ball mill was assumed to be 2 mm 2000 microns.
