Máy tạo hạt bụi, độ bụi TSI 3410
The Dust Aerosol Generator Model 3410 comes in two versions that differ in the way the powder is fed to the disperser.
- Model 3410U is for poorly flowing powders at low dosing rates (>50 mg/m 3 ). Here the powder is continually poured onto a metal ring where excess material falls off the side and back into the reservoir.
- Model 3410L meters powder using a moving toothed belt. The well-defined spaces between the teeth ensure a constant and reproducible supply of powder and achieve mass concentrations of 0.5 to 160 g/m 3 .
Both versions disperse the powder via an ejector nozzle with ceramic inlay to make it more resistant against abrasive material. Shear forces in the ejector nozzle disperse and de-agglomerate particles. In both models the reservoir can be refilled while in operation to accommodate any required dosing interval.
