Studies in Ultrafine Particle Production

Abstract

Ultra fine grinding has attracted many industries for the better product quality. It has been seen that new developments in electronic industries have demand for the desired size distribution (narrow distribution) offine sizes. Attrition mill has specific advantage over other conventional milling equipment such as Ball Mill and fluid energy mill due to the energy saving in the combination process. An attempt has been made to study the performance of grinding in a laboratory Attrition millfor the control of the product size distribution.The experiments were carried in the laboratory Attrition mill and the effect of ball size distribution on product size distribution was studied. The study was concentrated in the estimation of the comm inution functions such as specific rate grinding by experimental techniques. The experimentally estimated breakage distribution functions were used to predict the rate of grinding, and the product size distribution.
