Maintenance Services

To get high efficiency & free of troubles of belt coveying system, it is important that to preventive maintenance program shall be well preformed since belt installation.

To maintain a well operation to belt conveying system, a good, periodical housekeeping to the belt is essential.
A build-up of material on pulley and idlers will cause belt misalignment. If it is large enough, belt will strongly touch or even fold into the steel frames of conveyor line. This will damage belt seriously.
No one shall be allowed to attempt to remove material build-up unless the conveyor has been stopped completely.

While running, materials probably will spill and accumulated under the belt. Most of these accumulations can be removed and cleaned. But a special attention still has to be paid to the loading zone for preventing the spillage touch the idlers and probably will damage the idlers.
If idlers are frozen by spillage, the shells of idlers will become sharply because of continuous abrasion with the running belt. This will badly damage the cover rubber and carcasses of belt. Meanwhile, the power of consumption will be increased, as jammed idlers and pulleys are blocked by spillage.

In tail pulley & take-up zone, impingement occurred after between belt and pulleys. Once this situation occurred, belts carcasses as well as pulley′s surface will be broken as parts of their tensions now are over the rated tension of the belt. This impingement will be varnished only until the material build-up is broken or disappeared. Same damages to the belt in areas of jammed idlers & bending pulleys will be happened when a material build-up sticky on the belt′s carried side.
A proper management to the loading will be helpful for preventing the impingement.
(a) Accurate surcharge angle and loading.
(b) Appropriate match the running direction between loading speed and belt speed.
(c) Try to catch spillage if necessary.

For trough idlers, the strain that occur in Junction Points will be dangerous influence to the belt and mire it into the space of these point. This influence will cause belt a longitudinal break of separate it into plies in the zone that corresponding to the Junction Points tracing area. Air, sands will easily enter into the belt from these separating bubbles. In the end, parts of belt will mire into the idlers and be destroyed by conveyor machine before they are separating along the tracing area.
Many factors will cause the strain being occurred in the Junction Points. Larger angle of trough idlers, the more strain will be occurred. It will be much help to less the strain, if the angle can be reduced.
Transition Distance also is an important factor. If the distance is not big enough, belt will suffer strong strains in these points and probably will be destroyed in a very short time.
