The Dust Feeder / Dust Disperser SAG 420 is a device for generating solid aerosols by transforming a powdered solid into the air-floating state and has a very large dosing range.
enhanced dosing range: 6g/h...12kg/h
under operating conditions easy refillable
mass flow control by weigh scale option
In applications where air-floating particles are required such as testing of the separation performance of filter media an aerosol with certain, well-defined characteristic features and stability over a period of time is to be used. If the aerosol is produced from a certain powder the characteristic features of the generated dust will be determined by the powder. Additional characteristic features of the aerosol are achieved by transferring the powder into the air-floating state.
The process is divided into two parts: the continuous dosing of the powder mass flow and the dispersing (thinning out) of the powder preferably down to the primary particle size of the material.
Applications
Charging of filters, filter media and separators with dust
Generation of dust to determine the fractional as well as the total separation efficiency
