Sequence of Operation – After belt has been properly trained while running empty, check to see that electric controls are properly wired to provide proper starting and stopping sequence.
Loading – After checking the operating sequence, start with a light load and gradually work up to the designed load. Check chutes to see that the material is being directed onto the center of the belt. The loading point of a belt conveyor is most generally the critical point.
The ideal condition is to have the material pass from chute to belt at the same speed and direction of travels as the belt, with a minimum amount of impact. The skirt seals should be adjusted to prevent side spillage of material and to form the load centrally on the belt.
Belt Retraining – With the belt conveyor operating under normal load, check the belt for any run out. If necessary realign idlers as described in “Belt Training” above.
Starting and Stopping – Material should not be discharged onto a conveyor that is not operating. Conversely, when stopping a belt conveyor or conveyor system, stop discharge of material onto initial receiving conveyor and then in succession, the remaining conveyors after each has run off its load.
Loading – Apply load gradually. Do not overload, or convey material of larger size of type than that for which the conveyor was designed.
Chutes – Chutes should deliver material to belt centrally, without excessive impact, and in same direction and velocity of belt travel. Chutes should be kept clean and free of any material that may have formed into chunks. Inspect periodically for any trapped material between belt and chute.
Skirt Seals – Skirt seals should be checked occasionally to see that they are adjusted properly, and material has not become trapped between skirt and belt, thus causing abrasion to belt.
Scrapers – The scrapers are located at the head of the belt conveyors to remove material from belt and into receiving chute instead of bypassing chute and possibly accumulate on belt. A counterweight or spring keeps the scraper blade against the belt. Proper field adjustment is required periodically.
