How to quickly repair the belt scratch or tear of coal conveying system

At present, many coal plants use conveyor belts to transport materials, but I don't know how to repair the conveyor belt when the materials are scratched. There are two kinds of scratches on the conveyor belt, one is penetrating and the other is impenetrable. The two repair methods are basically the same, and the specific operation steps are as follows:

Non-penetrating scratch: polish the damaged part with a high-power low-speed angle grinder with a tungsten steel polishing disc, then clean the polished surface with a cleaning agent sk353, mix the cold vulcanized rubber sk3 13 and the curing agent evenly in proportion, apply glue to the damaged part, and apply it again after drying. In addition, apply a layer of cold vulcanizate on the bonding surface of the repair belt. When it sticks to the back of hand slightly, stick the repair strip on the damaged part and compact it with a compaction roller.

Penetration scratch: the steps are basically the same as penetration, except that the repair strip is stuck on the bottom first, and the rest are the same.

Thick conveyor belts will be used to transport coal, and selected materials should be used to repair it, otherwise it may not be as simple as scratching next time, and it is not impossible for the conveyor belt to break.
