Abstract
The effect of mill diameter ( D = 74.3 , 86.6 , 99 and 112.5 mm ), ratio of feed volume to mill volume ( V - 10,30,50,70 % ), number of balls ( N = 2,3,4, 5,6 and 7 balls), ball diameter (d = 10,20,30 and 37.5 mm), mill speed (RPM - 60,80,90 and 100% of max. mill speed), grinding time (T - 10, 20,30,40 and 50 min) and feed particle size (x, = 2000,1000,500 and 100 μm) on the increase in specific surface area of the ground Alumina Oxide has been investigated. The ground materials were screened by using normal and micro sieves down to 45 micrometer to give a complete analysis of the ground product. The increases in specific surface area of the products were evaluated. The results of the best operating conditions that achieve high increase in specific surface area of the ground Alumina Oxide with low energy consumptions were tabulated in table (3).
