The Börger Bioselect stands for efficient separation technology.
Using a purely mechanical process, liquid parts are separated
from solid parts in the medium (such as digestate or liquid manure).
PERFECT SEPARATION RESULT
The media to be separated find their way through the inlet opening (1) into the vessel-like
Bioselect. The outer cylinder is separated from the auger (3) by a roundly sealed wire-
wound screen (2) pipe. The auger has a frictional connection to the drive. The imported
liquid flows into the screen area next to the drive. The liquid flows through the wedge wire
screen (2) into the outer vessel area. The liquid drains through the liquid outlet (4).
The solid contents remain on the screen surface. They are conveyed into the press chan-
nel (5) by the rotating auger (3). Powerful subsequent dewatering takes place in the press
channel (5). The rotating auger has a Multi Disc (6) (sealing disk), which can be shifted in
axial direction, at the non-drive end. The adjusting unit (7) presses the Multi Disc against
the auger and the compressed thick matter plug. When the thrust force of the plug is
greater than the spring force of the Easy Shift unit (7), a slot for discharging is created by
axial movement. A scraper edge is used to loosen and expel the solids.
Liquid penetration is impossible due to the Multi Disc technolo-
gy (6). The Multi Disc (6) seals the press channel (5) as long as
the required drying stage of the thick matter plug is achieved.
This is when the slot for discharging opens and the solid phase
is loosened and expelled – penetration-proof technology.
