Comparative Study on Improving the Ball Mill Process …
Natural silica sand was collected from Peshawar city located in the North West Province of Pakistan. This silica was thoroughly washed and dehydrated in furnace up to 140 °C for an hour to remove impurities. Improving silica sand particle size was done using an acid–base filtering process to minimize metallic impurities in the final product.
Effect of operational parameters on the breakage mechanism of silica …
The size reduction of silica was intensive as the jet mill is energy intensive. Abrasive and destructive breakage mechanisms took place varying according to the operating conditions of the jet mill. The minimum particle size obtained was 3.15 μm with a span value of 1.30. The circularity value of the ground silica ranged from 1.29 to 2.02.
