Solid-particle aerosols are used for research, development and quality management in numerous fields. They are produced by dust generators. In case dry and easy flowing substances are applied, the dust generators of the model series SAG 410 are suitable.
They transport the solid material using a dosing belt (VDI 3491-3). This ensures a continuous, constant and exact dosing. The dust generators of Topas GmbH consist of a control unit and a dispersion unit.
The modular design enables the user to realise a wide range of powder mass flows. The fine adjustment of the powder mass flow is done by a comfortable infinitely variable control of the belt speed. Finally, the powder is transported by suction from the dosing belt and dispersed using a two-component nozzle (designed in accordance with ISO 5011).
In case poor-flowing powders such as Pural NF are used for the generation of aerosols, the dust generators SAG 410/U or SAG 410/P are suitable. The transport of the solid material is performed by a feed screw and dosing ring. If the used solid material also tends to adhere to surfaces, the use of a special nozzle (P-nozzle) ensures the suction of the solid material from the dosing ring.
The generator models SAG 410, SAG 410/L and SAG 410/H, SAG 410/M, SAG 410/V use the same principle of feeding the powder by a special feeding belt. The defined segments warrant a constant and reproducible supply of the powder even in small quantities. The resulting particle number concentration of the output aerosol can be easily adjusted by setting the feeding belt speed over a wide range.
Filling the small segments is realized by the scraper. Its design enables a constant dosing of the powder that is nearly independent of the powder reservoir filling level. The reservoir can be refilled during operation without any effects on the aerosol concentration.
The dispersing unit consist of a dual-stream ejector nozzle (similar to DIN ISO 5011) and a tube connection to the housing for compressed air supply. Shear forces created in this ejector disperse and deagglomerate the powder to form an aerosol.
