What Is A Dust Collector? | Aerodyne

Posted by Tom Hobson on Mar 30, 2023 1:15:00 PM

A dust collector is a mechanical device used to remove dust from an air stream. The dust collection system consists of a hood (or air collection device), the dust collector, the motive fan and any inter-connecting ductwork, stack, dampers, controls, etc. Aerodyne Environmental manufactures cyclone dust collectors and the dust handling valves (airlocks) mounted on the dust collectors.20181025_123137-1 

To properly specify a dust collector, certain information is required:

  1. Dust collector typeCyclone, baghouse, etc.
  2. Airflow (CFM) – The amount of air going through the collector. The airflow is critical to sizing a dust collector and without airflow no collector can be sized.
  3. Temperature, pressure, humidity of airflow – Higher temperature, pressure, and humidity will affect collector materials of construction, size and may require special valves and controls.
  4. Dust description* – The better you describe your dust the better your dust collector will operate. Example a sticky dust will bind a cartridge collector which will require frequent cleaning and/or replacing of the cartridges. While cyclones are well suited for sticky particulate.

    a. SG or density of the dust/particulate – the greater the density, the easier it is to remove.

    b. Dust/particulate loading (lbs/hr) – amount of dust.

    c. Particulate size distribution (microns) – how big is the dust (smaller dust is removed in baghouse but larger dusts can be effectively removed in a cyclone).

    d. Fibrous, abrasive, hydroscopic, granular, tendency to bridge, sticky, etc. (dust with these properties can wreck havoc on baghouses and cartridge collectors.
  5. Removal efficiency required – The greater the removal efficiency, the more expensive the design will be.
  6. Materials of construction required – from carbon steel to stainless and high alloy steel, the materials of construction affects price. Process conditions (temperature, gas/air composition, dust composition and humidity) can require specific materials of construction. (Example: salt in a humid environment requires stainless steel to prevent corrosion.)

    *If unknown, a pilot unit can often be rented from the manufacturer to test on your existing system.

Inspired To Be Different.

At Aerodyne, we choose to take a different approach to collecting dust and handling materials. Our cyclones are unique in design to address common issues such as problematic dusts and space constraints. Our airlocks are chosen to fit your specific application instead of hastily installing traditional equipment options. We believe that when we see things differently, we can solve problems effectively. That's why so many people turn to us for help in solving their tough dust problems.
