HEUBACH – Dustmeter Typ III Basisgerät mit Zubehör für granulatförmige Produkte
Measurement Principle The sample is placed into the steel drum (1). When rotated, three blades inside the steel drum simulate handling and conveying. A precision air flow control system provides a constant flow of air that carries air borne particles through a coarse particle separator (2) onto a filter (3) mounted in a filter housing (4). The dust quantity is measured in the majority of cases by simple weighing the filter. If required, the dust can be extracted from the filter for further analyses as for example determination of particle size distribution or chemical composition. Type III: Varies from "Type I" by a special dust generation chamber (6) equiped with an impeller (7) and four steels balls (8) causing forces of attrition to the sample, especially to granules or pellets. The released dust resulting from attrition is collected on a filter and available for further analyses Verkauf nur an Unternehmen.
