Processes in the chemical and formulation industry generate dust/air mixtures, many of the chemical components are flammable and, when dispersed, explosive. During the process, particles of bulk solids are atomised in the air and create a dust/air mixture with explosive concentrations of combustible dust.
An ignition source in the vicinity of such an explosive mixture leads to an explosion which can have a destructive effect on equipment and pose a health risk to employees.The main technological processes associated with explosive concentrations of combustible dusts:
- transport of bulk ingredients (pneumatic or mechanical systems);
- aspiration processes (cyclone separators, filtering systems, etc.);
- storage, sampling, weighing and dosing of bulk solids (silos, bins, scales, etc.)
- mechanical separation or mixing of materials and ingredients (mills, crushers, etc.).
