How to Control Dust in Half-Wet Material Crushers?

Dust control in Half-Wet Material Crushers focuses on source sealing, negative pressure dust collection, and explosion-proof cleaning, offering quick and easy implementation. I. Source Sealing (Most Critical) • Fully seal the feed inlet, discharge outlet, machine cover, and bearing seats, adding flexible connections and sealing strips to reduce spillage. • Equip with a sealed belt/screw conveyor to prevent open-mouth material discharge and dust generation. • Control the material moisture content to 30%–50%; excessive dryness results in excessive dust, while excessive moisture easily leads to machine blockage. II. Negative Pressure Dust Collection (Standard Solution) • Each feed and discharge outlet has a dust suction port connected to a pulse bag filter, ensuring airflow matching and stable negative pressure. • Short, straight pipes with few bends prevent dust accumulation and blockage; the dust collector is equipped with an ash discharge device for dust recovery and reuse. • Dust concentration is controlled at ≤30mg/m³, meeting emission standards. III. Explosion and Fire Prevention (Mandatory) • Equipment, pipelines, and dust collectors must be grounded against static electricity. Open flames and smoking are prohibited. • Spark detectors and explosion vents must be installed. Motors and electrical controls must be dustproof and explosion-proof. • Dust accumulation must be cleaned every shift. IV. Workshop Auxiliary Facilities • Forced ventilation with slight negative pressure in the workshop to prevent dust diffusion. • Spray mist cannons in the operating area to suppress dust. • Personnel must wear dust masks and goggles and take appropriate occupational protection measures.
