How to prevent dust from coal conveying cable trays
There are a wide range of techniques available to control and prevent dust from becoming problematic. Misting cannons have become the predominant method for dust management based on their ease of use, cost-effectiveness and proven success. Coal handling plants (CHPs) generate significant amounts of dust during processes such as coal crushing, screening, loading, unloading. In today's episode of the Dust Safety Science podcast, David Wood, Senior Technical Advisor at Benetech Inc., discusses redesigning chutes and conveyor systems to reduce fugitive dust. Coal dust is a contributor to lung disease and it therefore poses a threat to not only workers in these facilities but even to residents of. Fugitive dust on conveying systems is an ongoing issue faced by mines, transfer stations and utilities transporting, processing or burning coal, writes Mark Strebel, Division Manager, Martin Engineering. Effective dust control has become an increasingly important challenge, with raised awareness. Effective dust control in mining involves a combination of strategies tailored to specific operations and environments.
