Evaluation of the Dustiness of Different Kaolin Samples. | LitMetric

Evaluation of the Dustiness of Different Kaolin Samples.

J Occup Environ Hyg

a Department of Chemical Engineering, Universitat Jaume I, Castellón , Spain.

Published: April 2016

AI Article Synopsis

  • Several kaolin samples with varying particle sizes were tested for dustiness using the continuous drop method, adhering to EN 15051:2006 standards.
  • The study explored how properties like particle size distribution, specific surface area, and Hausner ratio relate to the materials' dustiness.
  • Findings indicate that factors like mean particle size and specific surface area significantly impact dustiness, which is crucial for reducing air pollution and ensuring occupational health during kaolin processing.

Article Abstract

Several samples of kaolin with different mean particle size were prepared and tested using the continuous drop method, one of the reference test methods according to standard EN 15051:2006 "Workplace atmospheres - Measurement of the dustiness of bulk materials - Requirements and reference test methods." On the other hand, with a view to relating the dustiness of the materials to their properties, particle size distribution, specific surface area, and Hausner ratio of these samples were determined. This article presents a characterization of these samples and an assessment of the influence of some material parameters on dustiness. The results show that dustiness may significantly be affected by mean particle size, specific surface area, and Hausner ratio. Moreover, it is highlighted that a detailed study of the influence of fine particles content on the dustiness was carried out. This information is deemed essential for establishing the most efficient preventive and/or corrective measures to reduce the generation of fugitive emissions of particulate matter during kaolin processing, both into the outside atmosphere (air pollution) and inside the facilities (occupational health).
