Dust suppression


Lenmontag Group is a production partner of the Russian State Hydrometeorological University (RSHU), provides dust suppression services using industrial highly efficient ecological dust suppression systems developed within the framework of a joint scientific and educational center.

Together with the Russian State Hydrometeorological University, we have developed and launched into production highly efficient environmental protection systems and construction technologies that provide a minimum load on the ecology of the construction area and industrial production.

Dust suppression guarantees clean air.

What we offer

The range of services provided by our company includes:

Integrated dedusting of offshore coal terminals

For marine coal terminals, dust suppression cannons and fog nozzle systems are used to effectively dedust the following components:

  • open warehouses for bulk cargo;
  • stacker reclaimers;
  • transfer stations;
  • ship loading machines.

For each of the above nodes, well-grounded solutions are developed using the best and available technologies (“dry fog”, “wet fog” and other methods according to the BAT Guide, 2019) with full automation of the process of controlling the operation of dust suppression systems according to the principle of “optimal climate”.
Equipment supplies are provided on a turnkey basis from the development of working documentation to service maintenance.
– when using our systems, a decrease in the level of dust content up to 90% was noted
– according to the report of JSC “Scientific Research Institute for Atmospheric Air Protection”
even in precipitation conditions (the surface of the material being loaded is wet), a decrease in dust content is noted. A significant decrease in the content of suspended dust particles was recorded at
80% (from 1116.0 to 224.0 mg / dm3),

Complex dedusting “DRY FOG”

Dry fog systems provide the most efficient form of dust suppression available on the market and have been recognized as the best technology for dust suppression in coal preparation plants, dedusting of various grades of coal, mining, crushing, beneficiation and transportation, as well as mining and metallurgical plants. Our low water flow fine atomization systems create “dry fog” with droplets of 1-10 microns that easily agglomerate (bind) dust particles down to 10 microns. “Dry fog” increases the weight of dust particles with a minimum of moisture, so particles in the air settle (return) back into the rock without significant moisture in the product.

We offer reliable, low-maintenance and low-maintenance UDS “dry fog” dust suppression systems that are specially designed and engineered to meet the high performance requirements of our customers to prevent dusting without dampening the material.
Advantages of “dry fog”: The reduction efficiency of suspended dust particles of 10 microns and 2.5 microns is close to 99%. Humidification of the product less than 0.023% moisture by volume.

Our company’s “dry fog” systems allow meeting the requirements for environmental and sanitary safety, fire and explosion safety, as well as qualitatively increasing productivity, profitability, safety and health of employees for production requirements.

We use modern technologies, including:

  • irrigation technologies BAT B-2 * “to prevent dusting”
  • irrigation technologies BAT B-3 * “for absorbing and settling dust” = dry fog, wet fog
  • optimum climate technology

Our capabilities

  • Development of technical design and working documentation (including calculation of efficiency)
  • Full automation of control based on a local meteorological station and implementation in the APCS
  • Automatic control of dust content in the air in the working area / at the border of the SPZ
  • Control of throw range (50, 100, 150 m) and injection flow density (60, 120, 180 psi)
  • Installation, installation supervision, construction and installation work, commissioning, commissioning
  • Monitoring efficiency and interaction with sanitary epidemiological authorities
  • The range of services of the Laboratory for Chemical Analysis of Natural Environments of the Russian State Medical University is used:
      • analysis of water, soil, soil and bottom sediments for industry and construction;
      • environmental support for the implementation of projects for the construction of structures on land, rivers, lakes, reservoirs and the sea shelf;
      • monitoring of the state of the environment and ecology.
  • Warranty repair
  • Service 24/7

Why they trust us

For 30 years of successful work – Lenmontag Group has gained successful experience in performing work on especially hazardous,

technically complex and unique construction projects, including those in the Far North.

Lenmontag Group, as a production partner, together with the Russian State Hydrometeorological University (RSHU), within the framework of the scientific and educational center, have developed and launched into production highly effective environmental protection systems and construction technologies that provide a minimum load on the ecology of the construction area and industrial production.

Wide geography and many years of experience in various climatic conditions of Russia allow us to develop and implement the most effective and reliable solutions to dusting problems both at positive and negative ambient temperatures, guaranteeing high efficiency of the equipment.
