The powder was produced by planetary ball milling process. 15 ml alcohol was added into each ball mill tank, and the ball milling ratio was 30:1. The ball milling speed was kept at 150 rpm (revolutions per minute). The ball milling time was 7 h. The powder was dried in a vacuum oven at 60 ℃ for 3 h before being removed.
Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills. Ball mills are available in various contact materials to accommodate contamination and wear requirements.
For ball mill working capacity, the optimum process parameter level No.3 (2.0 L) with a value of SN ratio (-12.915) based on smaller-the-better characteristic while for ball milling speed level No.2 (105 RPM) with a value of SN ratio as (-13.386) based on smaller-the-better characteristic, is the optimum process parameter level.
The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill speed, rpm. The actual motor energy consumption is 5-10% greater than this due to ...
