    4 Reasons Foam Dust Control Is Better For Coal Handling

    Now you’re transported to a coal-fired power plant. The conveyor bends and winds its way up from the coal pile to the crusher and ultimately the furnace. At each transfer point the dust flies, the air fills with fine coal particles, and the dust respirator you’re wearing itches and restricts your breathing.
