Embedding Degree and Accessible Void of Fine Particles on Coarse Particle Surface by Rotational Impact Blending

Abstract

In this research, the embedding degree of individual fine particles coated by rotational impact blending is measured by image analysis and the relationship among the operational conditions is investigated. As a result, the embedding degree is enhanced with an increase in the peripheral velocity of the rotor blade, and the treatment time and with decrease in the fine-particle diameter.
Moreover, the accessible void area of the coarse particle surface is related to embedding degree and the surface uniformity in our former paper for coating with fine particles of multi sizes.
