Solid Aerosol Generator SAG 410 Flow visualisation Poor-flow test dusts and smallest feed rates A new generation of dust disperser has been developed for substances, which are difficult to handle because of their poor-flow properties, such as titanium dioxide, aluminium oxide and soot. The innovative principle consists of loading the dust on a dosing ring from which it is drawn off by the dispersing nozzle. This enables reliable feed rates and dispersing of cohesive materials as well as delivery of very small quantities of powder at low dosing rates. Optimization of combustion processes Solid aerosols are used in a variety of applications, aerosol and powder science, industrial processes and quality assurance tasks. The technique for the dispersion of dry dust and powders comprises two steps, the continuous supply of material to the disperser and the dispersal of the material as an aerosol. A proven method for metering powder to the disperser is to use a moving toothed belt. The well defined spaces between the teeth ensure 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 with ceramic outlet tube. A specially designed scraper ensures even filling of the belt spaces and minimises the influence of the powder level in the reservoir on aerosol mass flow.
