Abstract
Growth rate phenomena of a NaCl single crystal were observed under conditions of continuous micro-crystal feeding. Y type tube mixer was proposed as the micro-crystal generator. The particle size distribution (PSD) of micro-crystals was changed and the effect of PSD on the growth rate enhancement was investigated. As the results of experiments, the growth rate enhancement was not temporary but was maintained during slurry feeding and the degree of growth rate enhancement depended on residence time for micro-crystals.
