- the separating drum 1 therefore sits on two bearings, which are configured in diameter are that at the end faces 8, 8 'of the drum shell enough surface is available to direct the exhaust air or supply air by means of fixed supply and exhaust air nozzle 5, 6 in the drum or lead out of the drum Exhaust port 5. 6 are connected to the fan, not shown here, the supply air pipe 6 with the
- Pressure line of the blower and the exhaust port is connected to the vacuum line of the blower.
- Atmospheric pressure E (p;> p a ) can be divided. With the nozzle 5, air is sucked from the negative pressure region D and through the nozzle 6 air is blown into the drum 1 of the overpressure region E.
- the separation drum 1 is fixedly or adjustably mounted by means of two mounting brackets 7, 7 'at the end of a conveyor belt, not shown here. Further, the drum 1 is rotated by means of a drive 2 via a drive roller 12 in rotation. The drive 2 is fastened via a bracket 3 to the non-rotating end face 8 '.
- the drive roller 12 is located on the outer side of the drum shell of the driven
- the complete unit is placed with the mounting brackets 7 on site.
- drum with other, not shown here drive means e.g. Belt-driven chain drives are driven.
- FIG. 2 shows a sectional view transversely to the drum axis 14.
