Dustiness measuring methods of disperse powders

Industrial handling of bulk materials, for example to store, convey, mix, fill etc. often leads to dust emissions. Generated dust is closely related to health hazards and environmental pollution and often leads to fires and explosions. The dust liberation property of powders depends on a multitude of variables and also on the method and intensity of stressing. The present paper describes further developed resp. used dustiness measuring methods. it also describes particle measurement techniques and summarizes the measurement methods systematically.
