Metalfab Model APB Belt Feeder - Manual (Page 2)

Operation
After the bin has been charges with material, start the bin discharger and the Belt
Feeder simultaneously. These units should be electrically interlocked so that the bin
discharger cannot run unless the belt is running.
For variable speed drives with adjustable gates, set the belt speed at mid-range and
adjust the gate height to achieve the mid-range or normal running range of the Feeder.
For fixed gates, vary the belt speed until the rate required is achieved.
Constant speed drives require adjustment of the gate to achieve desired feed rates.
Adjustments
If the nozzle does not discharge a full flow of material, and a bin discharger proceeds it,
the eccentric weights of the bin discharger should be adjusted. These are the only
adjustments required. If there is no bin discharger, flow aids must be used on the
static bin.
Maintenance
All of the bearings on the Feeder are sealed and lubricated for life. After running, belt
take-up adjustment may be required. The Feeder is provided with standard take-up
bearings on the rear pulley. They should be adjusted uniformly to maintain belt
tracking.
To replace belt, loosen the set collars of the shaft bearings on the side of the Belt
Feeder opposite the drive. Remove the bolts holding the slider bed and guide rails.
Also, remove the bolts in the connector brackets. If the Feeder has idler pulleys,
remove the nuts holding them in place. The side panel can now be removed.
Once the panel is loose, the belt may be removed and replaced. Reassemble the unit
and adjust the take-up pulleys to achieve proper tracking.
WHEN INQUIRING ABOUT ANY FEEDERS, ALWAYS REFER TO THE SERIAL
NUMBER STAMPED ON THE METALFAB NAMEPLATE.
