Abstract: A system including at least one means for mechanical processing of surfaces using a blasting agent (5), in particular steel or cast iron beads. An additive (6) for degreasing and cleaning of the surface to be blasted (2) and/or of the blasting agent is provided with the blasting agent (5), and comprising a granular material (6), which exhibits a lower breaking strength under the mechanical stresses that the blasting agent (5) is subject to during the blasting procedure than the at least one means for mechanical processing of the surfaces themselves. As the granular material (6) breaks down, additional additive (6) is added into the blasting agent (5) such that the proportion of the additive (6) in the blasting agent mixture blend (5) remains largely generally constant even at a prolonged operation of the device.

Abstract: A method for improving flame resistance in filter systems in which an air flow charged with flammable aerosols is fed to a filter. The filter prevents a least a substantial portion of the flammable aerosol from reaching the air flow exiting the filter. A granular flame retardant material is fed to the air flow containing the flammable aerosols prior to the air flow containing the flammable aerosols being fed to the filter. The flame retardant has porous mineral granuales as an essential component.
