Metalfab Screw Conveyor - Manual (Page 2)

For standard drives, wire the motor for the proper voltage and check
the direction of screw rotation. All Conveyors are provided with right
hand flights and the rotation is clockwise when facing the discharge
spout. Proper motor fusing or heaters should be provided.
Operation
For Conveyors with shrouds or metering sections, a choke feed is
required. For Conveyors without these features, a regulated flow is
required to the Conveyor. When regulated flow to the Conveyor is the
mode of operation, then the Screw Conveyor should be turned on
either before or at the same time as the unit that is regulating the
flow.
Maintenance
The bearings should be checked periodically for wear. Increase in
amperage draw or excessive noise is a good indication of bearing
wear. The seal should also be checked for leakage. If leakage occurs,
repack the seal with greased cotton waste.
To remove the screw or drive end bearing on units of one (1) piece
assembly, the forward bearing plate should be removed with the
bearing in place.
Caution: All set screws should be loosened on bearing set
collars.
The screw may then be moved forward for complete removal or moved
forward partially for removal of rear bearing.
Intermediate bearings are of two (2) piece construction and can be
removed without disassembly of the screw assembly.
Coupling inserts and belts should also be checked for wear on a
regular basis. It is suggested that bearing, belts or coupling inserts
and a screw section be kept as spare parts.
Note: Before maintenance is performed, motor should be
electrically locked out.
