When belt cover and the carcass wear out, it can be understood that the conveyor belt has attained its maximum life. If the belt is removed due to carcass damage even with the cover thickness in place, the cover life is wasted. On the contrary when the belt cover is worn while the carcass is still in place, the belt life is shortened. In order to obtain maximum life of the belt there are some factors to be considered. This includes:
Apart from these the quality and scope of repair can affect the life of the belt. It is a rare scenario that bulk material handling conveyor belt runs without any repair to its optimum life span. A belt that runs without any repairs are sure to be withdrawn from service before it reaches its maximum potential.
The question that arises from the management point of view is its economical feasibility and worth the expenditure. The repairs have to be justified to prevent downtime. In all these, cost is a major factor. The repairs have to be reviewed including the techniques. It is here that the rigid policies like, repair the damaged belt always, discard the damaged belt always and replace the damaged belt always, can lead to error.
Before initiating a repair it is important to interrelate many situations and these include to consider the extent of the damage, time span, feasibility of temporary repair, techniques to be used, type of supplies available, workforce, additional cost, availing services of outside contractors, insurance if any and bypassing materials handling.
In all these situations the conveyor belt repair material plays a pivotal role. The quality of the material is important to extend the life of the belt.
