A fog cannon or mist cannon works on a simple and effective principle: it creates a controlled mist cloud that binds with airborne dust and brings it down safely.
Step 1: Water is pressurized and filtered
Water is drawn from a tank or pipeline, passed through filtration, and delivered to the nozzle header at the required pressure to avoid clogging and ensure stable spray.
Step 2: Nozzles create fine droplets
Special nozzles atomize water into micro droplets (typically in the 10–100 micron range). The droplet size is selected based on dust type—fine dust needs finer droplets for better binding.
Step 3: Fan throws the mist to the dust zone
A high-power axial fan propels the mist forward, forming a mist curtain and giving longer throw distance to reach dust sources like crushers, conveyor transfer points, stockpiles, and unloading areas.
Step 4: Dust binds with droplets and settles
Airborne dust particles collide with the mist droplets, become heavier, and settle faster—reducing dust spread, improving visibility, and keeping the work zone cleaner.
Step 5: Rotation and oscillation cover a wider area
The cannon can rotate (up to 360°) and oscillate to cover large yards or target specific dust points, ensuring consistent dust control across active zones.
Step 6: Control options improve efficiency
Timers, remote control, and adjustable spray direction help reduce water usage while maintaining effective dust suppression during loading, dumping, and material movement.
