2. Air-to-cloth ratio - Wikipedia

   en.wikipedia.org/wiki/Air-to-cloth_ratio

   The air-to-cloth ratio is the volumetric flow rate of air (m 3 /minute; SI m 3 /second) flowing through a dust collector's inlet duct divided by the total cloth area (m 2) in the filters. The result is expressed in units of velocity .

   Airborne particles are commonly either biological contaminants, particulate contaminants, gaseous contaminants, or dust. This diagram shows the size distribution in micrometres (µm) of various types of airborne particles.

4. Dust collector - Wikipedia

   en.wikipedia.org/wiki/Dust_collector

   Dust concentration and particle size – For minerals processing operations, the dust concentration can range from 0.1 to 5.0 grains (0.32 g) of dust per cubic foot of air (0.23 to 11.44 grams per cubic meter), and the particle size can vary from 0.5 to 100 micrometres in diameter.

5. Hopper (particulate collection container) - Wikipedia

   en.wikipedia.org/wiki/Hopper_(particulate...

   Materials can be added either manually or automatically to the top of a hopper. For dust collection, it enters the hopper from a collection device. For example, baghouses are shaken or blown with compressed air to release caked-on dust from the bag. Precipitators use a rapping system to release the dirt. The crumbling dust falls into the hopper.

   Reverse pulse-jet dust collectors can be operated continuously and cleaned without interruption of flow because the burst of compressed air is very small compared with the total volume of dusty air through the collector. On account of this continuous-cleaning feature, reverse-jet dust collectors are usually not compartmentalized.

7. Particle-size distribution - Wikipedia

   en.wikipedia.org/wiki/Particle-size_distribution

   Particle size distribution can greatly affect the efficiency of any collection device. Settling chambers will normally only collect very large particles, those that can be separated using sieve trays. Centrifugal collectors will normally collect particles down to about 20 μm. Higher efficiency models can collect particles down to 10 μm.
