The Best Dust Collector is One that is Planned,
Designed and Manufactured Specifically for You.

Wet ScrubbersSeveral factors must be taken into consideration when purchasing and installing a dust collector. Among other things, we should take into account the unit’s design, operation and efficiency; the overall dimensions of the equipment and its construction; as well as purchasing, operating, and maintenance costs. This is where the MGB FAB Engineering Team, under the supervision of Mr. Pierre Bonnier, Eng. stands out. 

Each type of dust collector has its advantages and disadvantages. However, the selection of a dust collector should always be based on the following factors: 


  • The Concentration of Dust and the Particle Size - For example, during mineral processing operations, dust concentrations can range from 0.1 to 5.0 grains (0.32 g) of dust per cubic foot of air, and the particle size can vary from 0.5 to 100 µm. 
  • The Level of Dust Collection Required - The degree of dust collection depends on its potential as a nuisance to health, the location of the factory, the allowable emission rate, the nature of the dust, and its recovery value, along with several other factors. Whether you have high efficiency equipment such as electrostatic precipitators which are very expensive, equipment with high yield at an average cost such as bag filters and wet scrubbers, or inexpensive options like the primary units of centrifugal dry collectors, the selection of a collector should first be based on efficacy.
  • The Characteristics of the Airflow - Additionally, the characteristics of the airflow can have a significant impact on the selection of a collector. For example, cotton fabric filters cannot be used when the temperature is above 180 degrees Fahrenheit (82 degrees Celsius). In addition, the condensation of water vapor may affect the bags. Various chemicals can also attack the fabric or metal, causing corrosion of the equipment. 
  • The Characteristics of Dust - Some dust concentrations from moderate to high (like silica sand or metal ores) can become too abrasive for dry centrifugal collectors. Hygroscopic materials may also bog down the collectors’ bags. Stickies can adhere to the equipment and the ducts.  Since certain shapes and sizes of particles can do this, we should exclude certain types of fabric collectors.
  • Disposal Methods - Methods of removal and disposal of dust vary according to its composition, plant processes, or the volume and type of sensors used. Collectors can be emptied continuously or in batches. Dry materials can create secondary dust problems during disposal, which does not occur with wet scrubbers. On the other hand, the disposal of sludge may cause handling problems, especially in sewers or water pollution levels if wastewater is not treated properly.

When the MGB FAB Engineering Team examines a particular dust extraction or filtration problem, all of these factors are view site in order to design reliable components, which will give your equipment optimal efficiency and a positive return over the years.
