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.
