Sampling and characterization research: Developing two tools for powder testing
You'll find researchers hard at work on bulk solids handling and processing problems at academic institutions throughout the world. At Laurentian University in Sudbury, Ontario, Dr. Brian H. Kaye's studies have led to the development of two tools for powder processors. One is a tumbling sampler that can handle very fine powders; the other is a flow characterizer that studies powder avalanching. This article describes the research behind these developments and discusses how the devices work. No product endorsement is intended.
Obtaining representative powder samples and efficiently characterizing powder flow will help you solve many bulk solids handling and processing problems. For instance, good samples ensure your mixing or sizing test results are accurate; effective powder characterization can help you predict flow changes in powder mixtures and the effect of flow agents on powders. The following information discusses research to develop two powder testing tools: a tumbling sampler and a flow characterizer.
