Dusts created during treatment processes (mixing, weighing, adding) will vary with regard to their content and particle size (from nano particles to granulate).
The volume of dust created during the handling of bulk material is usually not consistent - air displacement with raised dust occurs in varying degrees. This characteristic is of vital importance when selecting the proper extraction design.
Hazardous fumes may also be produced during mixing processes, such as when adding solvents.
Depending on the material, explosion protection measures may be required.
