DUST SUPPRESSION SYSTEMS
When ordinary water is atomized into dusty environments, dry fugitive dust particles absorb the water droplets causing them to increase in weight and cohesiveness. This causes the dust particles to settle out of the air either returning back into the process material or settle to the ground/
This range of misting systems produce 10-20 micron (or smaller) sized water droplets which suppress dust without wetting the process material, your equipment and facilities.
Our approach to dust suppression costs a fraction of traditional dust extraction equipment and avoids the moisture problems of common spray type system.
Truemist Misting Systems have been shown to be an effective method of Dust Suppression, Dust Abatement and Air Filtration. Our misting systems can effectively suppress or remove breathable fugitive dust particles from 1 to 1000 microns. Due to the high standards of workmanship and industrial misting experience, TrueMist Misting Systems meet or exceed EPA PM 10 standard for dust suppression.

what is mean by dust suppression system?
Dust suppression is a technique to contain both visible dust and non-visible respirable dust particles present in the atmosphere by spraying of liquids by strategically placing spray nozzles. Dust particles are either made to settle down or Agglomerate with micro liquid spray particles.
Dust suppression system is an assembly of drawing liquids from source and deliver the liquids at a specified pressure using spray nozzle and associated system and suppress dust.
Where the dust suppression systems are used?
It used in places where occupational and environmental standards are to be maintained which includes cement processing plants, coal handling plants, silica manufacturing units, limestone units, wood pulp processing units, Quarry as well as Public places
What are the benefits of dust suppression system?
Improved occupational, health and safety by reducing respirable and inhalable dust, irritation and vision impairment
Increased equipment performance and reliability
Improved production quality by avoiding chemical additives
Reduced Machinery maintenance costs with lesser wear and tear
Clean up costs reduced
Natural suppressant of unpleasant odors
Creates a cooler environment for workers on-site
What are the types of dust suppression systems available?
By place of installation
1. Indoor dust suppression system
2. Outdoor dust suppression system
1. Fogging or Misting system
2. Dust suppression cannons
1. Dry fog dust suppression system
2. wet dust suppression system
What is Particulate matter?
Particulate matter or aerosol particles is the sum of all solid and liquid particles suspended in air and many of the particles are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. These particles vary greatly in size, composition, and origin.
coarse particle size ranging from 2.5 to 10 µm (PM10 – PM2.5).
Fine particles are up to 2.5 µm (PM2.5).
ultra fine particles are smaller than 0.1 µm.
What are the different pressure range of dust suppression misting system?
Dust control Sprinkler systems uses a pressure range of 30 bar (435 PSI) (1 bar = 14.5 PSI)
High pressure misting system operates in the pressure range of 50 to 80 bar
Dust cannon operates in the pressure range of 6 bar to 20 bar
Factors to consider while selecting right dust suppression system your requirement
The process and material producing the dust. Availability of utilities and resources includes electricity, compressed air, water.
What is the dust particle size?
A dust particles ranging in diameter from 0.1 to 400 microns are airborne a dust particle of 5 microns will continue to follow the air stream around a water droplet of 200 microns, therefore, avoiding collision. With the dust particle and a water droplet of similar size, the air stream is not as great and collision occurs, causing agglomeration.
What liquids are used for dust suppression?
- Plain water
what are the nozzles used for dust suppression?
Selection of spray nozzles are based on drop size of the individual particles and spray pattern. Following spray nozzles are used for dust suppression.
• Air atomizing nozzles: produce the smallest drop sizes, followed by fine spray, hollow cone, flat fan and full cone nozzles.
• Higher pressures mist nozzles: yield smaller drops, and lower pressures yield larger drops.
• Low Pressure mist nozzles: Lower-flow nozzles produce the smallest drops, and higher-flow nozzles produce the largest drops.
• Fine Spray Hollow cone Nozzles
• Fine Spray Full Cone Nozzles
What will be the impact if the dust suppression is not performed in industrial setup?
- Violation of environmental and occupational standards
- Wear and tear of mechanical parts like conveying pulleys, idlers, belting and motors.
- Damage to conveyor equipment and other associated equipment
- Reduced productivity of employees
Our Industrial misting system for dust control helps meeting the environmental objective of Industries and Factories.
OUTDOOR DUST SUPPRESSION SYSTEM
Outdoor Dust Suppression Systems is designed in accordance with industry standards. With our own R&D, production and after-sales provide the perfect solution to solve your dust problem. we provide the best solution to dust problems. 1. Cold Fog Dust Suppression System
2. Plain Water Dust Suppression System
3.Sprinkler Dust Suppression System
INDOOR DUST SUPPRESSION SYSTEM
Dust Suppression System uses high-pressure water fogging which creates a fine fog consisting of very fine water droplets (less than 10-micron size) in diameter. These tiny water droplets absorb even the smallest dust particles in the atmosphere without making the ground wet and best suited for dusty environments.
DUST SUPPRESSION SYSTEM FOR CRUSHER PLANT
Dust Suction is widely used by installing higher capacity exhaust fan to recover suspended particles using special fabric. Operational expenses are very higher in this method. Installation by almost closely sealing all the moving parts, such as belts, screens, crushers, loading, and unloading duct.
The dust suppression sprinkler system sprinkle water at the points where dust is emitted. This is an economical way of suppressing the dust but the water consumption is higher. An efficient sprinkling delivery system reduces water consumption and the dust is suppressed effectively. Our dust suppression plant is based on the sprinkling principle by Water fogging.
WATER FOGGING MISTING SYSTEM
This system consists in applying to the points of dust emission like exchange points between the conveyor belts, hoppers, jaw and impact crushers, a spay of water with specially designed high-quality mist nozzles that produce a mist made of minute droplets. Each point of application is connected to a network of nylon tubing with pressurized water from 60 to 110 bars.
The water consumption is very low and the installation is quick and easy.
Upstream of the pressurization pump some filters having a fine mesh ensure the functionality of the system and avoid any clogging of the nozzles.
For the treatment on the transit or working areas we can supply fog cannons for a range up to 50 meters which are provided with an automatic or remote-controlled rotation system.
DUST SUPPRESSION SYSTEM IN COAL MINES HANDLING PLANTS
Water spray applications are one of the principal means of controlling airborne dust in coal mines. Since many coals are hydrophobic and not easily wetted by water, wetting agents can be added to the spray water in an effort to improve coal wetting and assist with dust capture.
- What is atomization?
It is the process of breaking up water into very tiny droplets between 30 to 200 microns
- How do I select a dust suppression system?
Various factors include industry, site layout, size of particles, weather, water pressure, application, and many other elements that involve the selection of the right type of system.
- Can water from any source be used?
Water from any source can be used but need to be filtered and then pumped to the nozzle as the impurities can damage and block the system.
- How often is maintenance required?
Depending on the usage and frequency the system requires minimum maintenance, nozzles can be removed and cleaned incase of any obstruction in spray flow.
- How long does it take to get a unit?
Depending on the size of the system required anywhere from 2 to 3 weeks.
