4.8 COMPLETE SYSTEM
The complete system of the press / screw separator also includes the material supply and discharge
handling.
The incoming material can be delivered by pump or from an elevated tank by means of gravity. Be-
cause the pump delivery rate cannot be precisely determined, an overflow is absolutely required in
order to protect the separator from an overload.
The pump should be designed to slightly ex-
ceed the capacity of the separator, but the
pressure on the separator should not exceed
2
m water column [0.2 bar]
. A higher pressure
would damage the seal in the separator.
In order to obtain a homogeneous mixture of
solid and liquid, a stirring machine is required
when supplying the slurry via a pump or from
an elevated tank.
It is very important that the supply of material to
the separator is always controlled by the switch
cabinet.
The correct selection of the pump, the stirring
machine and the supply and disposal lines is
critically important.
When supplying the separator from an elevated
tank by means of gravity, a flow regulator may
be required in some circumstances to limit the
pressure on the separator. In this case, an
overflow is not required.
The effluent should be disposed of via an open
(and thereby ventilated) drain channel or col-
lected in a drainage pit and then pumped out in
order to avoid generating a suction effect on
the separator. The ventilation is required be-
cause otherwise particles are drawn into the
screen gap and remain stuck there, blocking
the open screen surface and impairing the
function of the separator.
The separated solid can be piled up and trans-
ported away as needed, brought away on a
conveyor belt or disposed of by container or
truck.
The supply line available with the BAUER separator as an accessory is a reinforced yet flexible tube.
This reinforced tube is resistant to negative pressure. Ventilation openings can be added to the inflow
line through the connection of a breather pipe to the inflow element. The ventilation is required for a
pump with a very high pump capacity since the high flow speed in the overflow line would otherwise
produce a siphon effect that would limit the supply to the separator and impair the separation process.
