Complete System - Bauer S300 Original Operating Manual

4.8 COMPLETE SYSTEM

The complete system of the press screw separator also includes the material supply and discharge han-
dling.
The incoming material can be delivered by pump or from an elevated tank by means of gravity. Because
the pump delivery rate cannot be precisely determined, an overflow is absolutely required in order to pro-
tect the separator from an overload.

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.

The pump should be designed to slightly exceed
the capacity of the separator, but the pressure on
the separator should not exceed 2 m water col-
umn [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 elevat-
ed 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 ma-
chine 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 pres-
sure 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 collected
in a drainage pit and then pumped out in order to
avoid generating a suction effect on the separator.
The ventilation is required because otherwise par-
ticles 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 con-
veyor belt or disposed of by container or truck.
