Feeder System For Particle-Size Analyzer

Abstract

Feeder system meters precise stream of powder into precise flow of gas. Used to feed light-scattering particle-size analyzer that determines distribution of sizes of particles in powder. Dry analysis of powder takes about one-third time of conventional wet analysis and consumes less powder. Feed rate more precisely controllable, leading to more precision in analysis. In dry analysis, no need to dispose of hazardous liquid waste.
