In mine bins, the moment ore pours down from conveyor belts, grayish-brown dust explodes like mushroom clouds, filling the limited space. Traditional fixed dust suppression equipment has limited coverage and often struggles with dynamic dust from multiple unloading points. However, mobile trailer fog cannon machines, with their "flexible movement + precise dust control" features, have become powerful tools for dust reduction in such complex scenarios.

Core Advantages of Mobile Dust Suppression

The challenge of mine bin dust lies in its scattered sources and dynamic changes. Multiple points such as main unloading ports, transfer chutes, and temporary stockpiles can generate dust at any time, which is difficult for fixed equipment to fully cover. Mobile trailer fog cannon machines adopt a four-wheel trailer chassis design with a minimum turning radius of only 3.5 meters, allowing them to move freely in narrow mine bin passages and quickly reach wherever dust appears.

Their retractable fog cannon arms can adjust height within 3-8 meters, combined with 360-degree rotation function, enabling precise targeting of dust sources at different heights. Special wear-resistant atomizing nozzles break water into 50-200 micron fog particles, which effectively adsorb ore dust. The dust suppression efficiency is more than 4 times higher than traditional sprinklers, and it will not cause water accumulation and slipping on the mine bin floor.

Case: Dust Reduction Innovation in Iron Ore Bins

A large iron ore mine in Chile once suffered from severe dust problems in its main mine bin. This 20-meter-high and 800-square-meter mine bin handled 5,000 tons of iron ore through 3 conveyor belts daily, with dust concentration reaching up to 4.8mg/m³, far exceeding the national limit of 2mg/m³. Miners had to wear full dust-proof equipment and replace dust masks 4 times a month. Equipment in the mine bin had a 30% higher failure rate than other areas due to dust erosion.

Last year, after the mine introduced 2 mobile trailer fog cannon machines, the situation improved significantly. During operation, one fog cannon machine monitored the main unloading port, with its fog curtain automatically adjusting fog volume according to the unloading rhythm of the conveyor belt through remote control; the other patrolled flexibly, dealing with sudden dust in temporary stockpiles at any time. The fog cannon machines were also linked with mine bin dust sensors, automatically starting when the detected concentration exceeded 1.5mg/m³ and stopping when the concentration reached the standard.

Three months later, third-party testing showed that the dust concentration in the mine bin stabilized at 0.8mg/m³. Miners reported no choking sensations when removing masks. The amount of dust attached to equipment surfaces was reduced, and the maintenance cycle was extended from 1 month to 2 months. More importantly, the abnormal rate of occupational disease screening caused by dust decreased by 60%, and the mine bin was awarded the title of "Safe Production Model Post". It was calculated that the two fog cannon machines consumed only 12 tons of water per day, saving 60% compared to the 30 tons used by the original 4 sprinklers.

Multiple Values Beyond Mobility

The value of mobile trailer fog cannon machines in mine bins goes beyond flexible dust suppression. Their diesel-powered design allows them to work normally even in emergency situations such as power outages in mine bins, ensuring uninterrupted dust suppression. The equipment is equipped with a large-capacity water tank that can work intermittently for 8 hours continuously. With a quick water inlet, the single water replenishment time does not exceed 15 minutes, hardly affecting the normal production rhythm of the mine bin.

For enterprises with multiple mine bins, the sharing of such mobile equipment significantly reduces costs. Practice by a Vietnamese mining group shows that 3 mobile trailer fog cannon machines can meet the dust suppression needs of 5 mine bins, saving 40% of initial investment compared to installing fixed equipment in each mine bin. The intelligent control system of the equipment can also record the dust patterns of each mine bin, providing data support for optimizing production processes.

In today's increasingly strict requirements for green mine construction, mine bin dust control has become a must for enterprises to achieve compliant production. Mobile trailer fog cannon machines, with their features of flexible coverage, efficient dust suppression, water and energy saving, provide targeted solutions for complex scenarios like mine bins. When iron ore falls from the conveyor belt again, the fine water mist sprayed by the fog cannon machine locks the dust at the source in time, protecting miners' health and building a solid environmental defense for the sustainable development of mines.
