Custom Made Micronized Silica For Paint Industry Via Fine Grinding Process

by Samayamutthirian Palaniandy et al. Azojomo, 2 May 2006 The paint industry demands stringent filler specifications. Custom made mineral fillers with improvement in terms of particle size and shape during the fine grinding process will enhance the paint quality. An experimental work was carried out by varying the classifier speed of a jet mill to improve the particle size and particle morphology while the grinding pressure was kept constant. The control of the fine grinding process was essential as the classifier speed influenced the ground product in terms of particle size and shape. The highest circularity index, 0.962 was obtained at 10000 rpm with a smooth surface texture and trimmed sharp edges which fulfils the filler specification of the paint industry. Read more
