Page 6: Safety Conditions / Intended Use
For safety reasons, under no circumstances may the machine be commissioned if there is visible damage. In this event, please contact Palas® (Tel.: 0721/96 213-0). The dust disoerser has been set by the manufacturer to be used with a maximum pre- pressure of P 8 bar for the compressed air supply. -
Page 7: First Operating Instructions
OPERATING MANUAL RBG 1000 I RBG 1000 ID 3. First Operating Instructions Connect mains plug. Connect compressed air supply (4 - 10 bar overpressure) via a pressure reduction valve (or another suitable valve) to the generator and set desired pre-pressure (see volume flow curve). -
Page 8: Operating Principle
OPERATING MANUAL RBG 1000 I RBG 1000 ID 4. Operating Principle The Rotating Brush Generator RBG 1000 I or RBG 1000 ID transfers dry, non-cohesive powder and dust particles into an airborne state. The generator permits the solution of two basic problems relative to the dust- and powder technology. -
Page 9: Feed Rate And Mass Concentration
OPERATING MANUAL RBG 1000 I RBG 1000 ID 4.1 Feed Rate and Mass Concentration The feed rate relative to the mass, also called mass flow, indicates the amount of dust per time (dimension: gram per hour) which is propelled out of the powder dispersion generator. The mass flow M is exactly determined by the following parameters: diameter of powder reservoir compact density of powder inside the reservoir... -
Page 10: Dispersion Air And Dispersion Effect
OPERATING MANUAL RBG 1000 I RBG 1000 ID 4.3 Dispersion Air and Dispersion Effect Only use dry, oil-free and particle-free disperdion air. Wet air causes coalescation of brush and sedimentation inside of dispersion nozzle. A general rule is: the smaller the particles, the higher the required energy for their dispersion. -

Page 21: Filling Of The Powder Reservoir
OPERATING MANUAL RBG 1000 I RBG 1000 ID 6.2 Filling of the Powder Reservoir In order to obtain a constant feed rate while using a constant piston feed speed, a constant compact density must be maintained in the powder reservoir. The bulk material is slowly being fed into the cylinder, and each time its density is slightly regulated by compacting, in order to achieve a constant compact density. -
Page 22: Inserting Of The Powder Reservoir
OPERATING MANUAL RBG 1000 I RBG 1000 ID 6.3 Inserting of the Powder Reservoir A groove has been mill-cut to the side of the powder reservoir (see fig. 5). The counterpiece to this groove is a bolt located at the dispersion head to the left of the insertion opening for the powder reservoir. -
