Abstract

This paper presents the prototype of a device for measuring the dustiness of powdered materials by means of a new measurement method. The currently employed stationary laboratory device, utilised in KD “Barbara”, uses the attenuation of a radiant flux transmitted through a dust cloud induced by a manually generated air blast. The new device uses the same measurement method, but it includes modern elements based on a microprocessor, a laser line generator instead of an LED diode, and a precise multi-channel detector. The generated quantity of the mixture (dust and air) is strictly determined and precisely dosed via buffer containers, pressure sensors, and high-speed solenoid valves. Utilising the new solutions will make it possible to improve the repeatability of the air blast parameters and the detection of the dispersed dust cloud, which will enable a better evaluation of the tested dust quality. The paper presents a prototype of a device for measuring the dustiness of stone and lime dusts. The device can also be used to determine the dustiness of other powdered materials.
