For this purpose, ball milling time and speed were varied in the mechanical activation of the black dross after water treatment. The ballmilltreated black dross was dissolved in an NaOH solution by varying such leaching conditions as NaOH concentration, pulp density, and leaching time and temperature.

Jun 15, 2018· Size of the mill feed (80% passing in microns' size) = 15000 microns (15mm) Work index for the feed = 18 kwh/ %age of mill in critical speed = 70%. Specific gravity of the feed = gm/cm3. Mill effective diameter = m. 335 is a constant used for dry grinding with steel balls in the mill.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
