GB
These mounting and operating in-
structions apply to Kongskilde belt
conveyors types BCA and BCB.
Type BCA has a drive section with
chain and V-belt drive transmis-
sions. In type BCB the chain drive
is replaced by a gear drive. Apart
from the drive section the two types
of belt conveyors are designed
along the same lines.
Construction.
The BCA/BCB belt conveyors con-
sist of the following main compo-
nents:
- Drive section type BCA or BCB.
BCA
- Tensioning section Type 1 or 2.
Type 1 is a standard tensioning
section. If discharge is required at
the tensioning section, a discharge
outlet may be provided. Belt ten-
sioning will move the discharge
outlet further back.
Type 2 is designed to keep the
same position of the discharge
outlet independent of belt tension-
ing. Type 2 is therefore ideal where

accurate location of the discharge
outlet is desired.
- Inlet (fixed or movable).
Each belt conveyor may be provid-
ed with several inlets. The material
flow from any previous inlets may
pass freely under the inlet. Intended
for conveyance in both directions.
BCB
- Discharge unit (movable).
Intended for conveyance in one di-
rection only. The use of a discharge
unit requires horizontal position of
the belt conveyor. The discharge
unit has a two-way diverter to allow
discharge to both sides of the belt
conveyor.
- Extensions (0.33/1.0/2.0 m).
The total length of extensions may
reach 50 m.
- Belt (width 300 mm).
Assembly
BCA/BCB belt conveyors are
supplied from Kongskilde in pre-
as sembled main components for
erection as shown in the following
sketches (see page 20-22).
Note that the belt conveyor must be
supported at approx. 5 m intervals
and at the conveyor ends.
If it is not possible to mount a fixed
support for each 5 m, for instance
because the conveyor is mounted
on a running rail, provide the exten-
sions with diagonal bracings.
If the length of extensions exceeds
35 m, the BCA belt conveyor is
supplied as standard with return-
ing rolls. The use of returning rolls
reduces the power consumption as
well as the wear on the belt. It is
normally recommended to provide
