The Dust Dispersers of series SAG 410 for dosing and dispersing powders use the proven method of metering powder by a moving belt to the disperser like in directive VDI 3491-8 described. That ensures a constant and reproducible supply of powder, even at low feed rates. The particle concentration of the output aerosol can easily be adjusted over a wide range by changing the speed of the feed belt.
The powder is removed from the belt by an ejector nozzle (similar to ISO 5011).
Dust is often needed for tests, research and quality assurance tasks. It is defined as a dispersion of fine solid particles in gas. To produce such aerosols, often very small amounts of solids must be dosed consistently and continuously.
The new designed dust feeder SAG 410/U applies an innovative concept of a rotating stainless steel ring for dosing. By means of the ring very small amounts of powder can be fed.
Especially for poor-flow, cohesive materials the model SAG 410/P has been developed.
