Stone Crushing with Water Spray Technology Stone crushing has long been associated with exposure to airborne crystalline silica dust to both workers and those residing in close proximity to these operations. Water spray dust control measures are effective at reducing levels of respirable crystalline silica dust. Studies have reported reductions
Crusher dust doesn't exist in the natural world. Stone miners will extract suitable rocks from a quarry and then send them to a facility for refinement. The refinement process involves crushing the stones to create a fine powder-like material. Some refiners may add limestone, clay, or cement to increase weight and facilitate compaction.
