xIn industrial material yards such as sand, gravel, and coal storage areas, the dust problem has always been a major headache. It not only pollutes the environment but also affects production safety and the health of employees. Nowadays, the fog cannon machine brings hope to solve this dilemma.

I. The Great Hazards of Dust in Material Yards

Materials in material yards are prone to generating dust during loading, unloading, transportation, and under the action of wind. Dust pollutes the atmosphere, increasing the concentration of inhalable particulate matter. The risk of respiratory and cardiovascular diseases for surrounding residents has greatly increased, and their lives are also deeply affected. For the material yards themselves, dust leads to material loss, increasing costs. It also reduces visibility, causing potential traffic safety hazards and equipment failures.

II. The Dust - Suppression Principle of the Fog Cannon Machine

The fog cannon machine consists of a water tank, a high - pressure pump, a fan, and a spraying system. When it works, the high - pressure pump pressurizes the water in the water tank, and the spraying system forms fine mist droplets with a diameter of 50 - 200 microns. The fan sprays the mist droplets over a long distance. The mist droplets, due to their stickiness, adsorb dust particles. Subsequently, under the action of gravity, they settle, achieving dust suppression. Moreover, the fog cannon machine can adjust the spraying angle, height, and coverage area according to the situation of the material yard.

III. The Remarkable Advantages of the Fog Cannon Machine

(1) High - Efficiency Dust Suppression

Compared with traditional dust - suppression methods such as watering, the fog cannon machine is more efficient. Traditional watering trucks have a small watering range and fast water evaporation. The fog cannon machine can reduce the dust concentration in the material yard in a short time through long - distance and large - area spraying. For example, in a large sand and gravel material yard, when the fog cannon machine is turned on for more than ten minutes, the dust is significantly reduced.

(2) Energy - Saving and Environmental - Friendly

The fog cannon machine uses less water but has a good dust - suppression effect, saving water resources. Its energy consumption is also low, reducing operating costs. In addition, it has a long service life and is easy to maintain. In the long run, it saves a lot of expenses for the material yard and has a high cost - performance ratio.

(3) Convenient Operation

The fog cannon machine is easy to operate. Staff can control the start, stop, spraying angle, and wind power on the operation panel. Material yards of all sizes can select suitable models, and it can adapt to different environments such as high - temperature, low - temperature, and windy conditions, stably playing a dust - suppression role.

IV. Excellent Results in Practical Applications

A large - scale coal material yard had serious dust problems during the peak loading and unloading period. There were many complaints from residents, and it was also warned by the environmental protection department. After introducing the fog cannon machine and turning it on for dust suppression before loading and unloading, after a period of time, the surrounding dust decreased, air quality improved, residents' complaints reduced, material loss decreased, and economic benefits were also improved.

In conclusion, with its unique principle, remarkable advantages, and successful cases, the fog cannon machine has become an ideal choice for dust suppression in material yards, helping material yards bid farewell to dust and achieve green development.
