Cut down excessive water & power costs while keeping fugitive dust within compliance with YG dust cannons. Featuring 360° rotation, adjustable pitch, and remote control, our dust cannons adapt to diverse working sites. Spray range is only one of the variables. Learn how to select the optimal model from 5 critical dimensions for your dust management project.
Key Structural Components of Water Cannon Dust Suppression
The water cannon dust suppression system consists of multiple precision components, each playing a vital role in its performance. Below are the main parts:
Power and water system: Includes a water tank, pipelines, and a generator set (gasoline or diesel optional), combined with a plunger pump to provide continuous high-pressure water flow for stable spraying.
Spraying and control units: The nozzles and fan handle atomization and projection, while the horizontal rotation and vertical pitching mechanisms allow angle adjustment. The control box and remote controller simplify operation and improve flexibility.
Structural materials: The support frame uses galvanized steel pipes, the air duct cover is made of cold-rolled iron, and the fan blades are aluminum alloy, ensuring durability and corrosion resistance.
How to Select the Right Dust Cannon
The core principle of selection is not “the longer the range, the better”, but matching the equipment capacity with actual site conditions. You can evaluate it from the following 5 dimensions.
1. Confirm the coverage area and height of dust sources first.
Range determines the effective coverage radius of a single unit. The 20 m model is suitable for dust suppression at stockyard corners, small processing sites, and access gates.
The 30–40 m range fits medium-sized coal yards, stone processing zones and main working faces of construction sites.
The 60 m range is designed for large coal stockpiles, port terminals, and large-scale mining operation areas.
If dust sources are scattered at multiple points, two medium-range units usually deliver better coverage than one long-range unit. The spray from a single cannon forms a conical coverage zone, and droplet concentration drops significantly at long distances.
2. Verify water consumption and on-site water supply capacity.
Water consumption of the four models is 1000, 1500, 3000, and 7500 L/h respectively, while the water tank capacity is only 460–800 L. This means continuous water replenishment is generally required; the tank only acts as a buffer.
If stable tap water or reclaimed water pipelines are available on site, the unit can run with a direct pipeline connection.
If no fixed water source is available, a water tanker or large-capacity water storage tank shall be equipped.
The return pipe size is 1400 mm. Connection position and routing need advance planning.
Water consumption is proportional to range. Before choosing a long-range model, confirm whether the site can steadily supply the corresponding water volume.
3. Check power supply conditions.
All four models are electric, 380V/50Hz three-phase. Three-phase power access is required on site.
If three-phase power is unavailable, a gasoline or diesel generator set can be considered.
Total power ranges from approx. 7.5 kW for YG-20 to approx. 22.5 kW for YG-60. On-site power distribution capacity must be checked.
When the power source is far away, cable laying shall be planned in advance.
4. Determine automation requirements based on operation mode.
All four models support 360° horizontal rotation and -10°~55° vertical pitch, with remote control operation.
Fixed-point long-term dust suppression: Smaller-range models are optional, set at fixed angles for continuous operation.
Multi-direction coverage: 360° horizontal rotation covers the whole site. Match rotation speed with dust generation frequency.
Mobile operation or frequent relocation: Net weight ranges from 200–350 kg with compact dimensions, easy to transport by small vehicles.
5. Take special operating environments into consideration.
Corrosive environments (some chemical scenarios): The main barrel is made of Q235 carbon steel. Evaluate anti-corrosion treatment if exposed to corrosive media for long periods.
Low-temperature environments: Anti-freezing measures are required for water tanks and pipelines.
Disinfection and epidemic prevention: Confirm whether the sprayed liquid is corrosive to the Q235 carbon steel barrel and aluminum alloy fan blades.
Extremely high dust concentration: Anti-clogging design is needed for the fan air inlet.

To maximize the performance of the water cannon dust suppression system, regular maintenance and proper model selection are essential. Practical recommendations include:
Routine maintenance: Check nozzles and fans for blockages, clean water pipes and filters to ensure atomization performance, and lubricate rotation mechanisms to prevent jamming.
Model matching: Choose the appropriate model based on the parameters table—YG-40 is suitable for medium-sized sites, while YG-60 fits large mining areas to meet distance and water usage requirements.
Professional support: Contact the supplier for periodic inspections, replacement of worn parts, and use of genuine components to ensure the fog cannon machine operates reliably over the long term.
Coverage depends on range and installation position. Under ideal conditions, a 40 m cannon can cover a fan-shaped area with about a 40 m radius. Actual effective coverage is affected by wind speed, wind direction and droplet size distribution. For large stockyards, zoning layout with multiple units achieves more uniform coverage than a single long-range cannon.
Q: How many units do I need?
Judge by the distribution of dust sources. Mark all dust generation points (loading/unloading points, crushing outlets, material piles, haulage passages), then divide zones according to the effective coverage radius of each cannon. One unit is enough for concentrated dust points with limited area; multiple medium/short-range units are usually more practical for scattered points or large areas.
Q: What materials is the equipment made of? Will it rust outdoors?
The bracket is galvanized pipe, the fan shroud is cold-rolled steel plate, fan blades are aluminum alloy, and the main barrel is Q235 carbon steel. Galvanized brackets and aluminum alloy blades have good weather resistance. For Q235 carbon steel barrels used outdoors long-term, check the surface coating specification or assess extra anti-corrosion solutions according to the working environment.
Q: Can it be used for purposes other than dust suppression?
Yes. Other applications include disinfection and deodorization at landfills, large-scale sterilization after public health events or natural disasters, epidemic prevention operations, and pesticide spraying for landscape departments. For these uses, confirm the chemical liquid’s corrosion resistance to Q235 carbon steel barrels and aluminum alloy fan blades; anti-corrosion treatment is needed when necessary.
