Simple Instrument for Estimating the Dust in Granular Particles

Abstract

Many minerals used in the form of grains in industry, such as abrasives and refractories, are formed by crushing a large mass of fused material. The process of crushing leads to dust formation; this dust becomes adsorbed onto the grains. Many incoming material inspection standards do not cover dust testing. Dust is detrimental to further use of the granular particles. The present study describes a simple instrument to test dust in granular materials and illustrates its utility in solving a rejection problem that occurred during abrasive wheel manufacturing.
