Which kind of cover rubber is better for conveyor belt joints?

Which kind of cover rubber is better for conveyor belt joints? It depends on the quality of conveyor belt, such as a reconditioned conveyor belt, even you choose the best cover rubber, the quality is still bad, why? This kind of conveyor belt has been vulcanized twice, rubber and canvas layer has been aged, so the quality of this kind conveyor belt is not good. However, coal mine plant, Power Plant, Cement plant, port and steel factory should choose better cover rubber for conveyor belt hot splicing jointing, why? If the quality of cover rubber is not good quality, this will cause the break of conveyor belt while high speed running, so will lead to bad consequence.
Suggest brand: Ramimtech conveyor belt jointing cover rubber

Ramimtech conveyor belt jointing cover rubber includes uncured intermediate rubber, uncured cover rubber and hot vulcanizing solution SK823. Mainly used for conveyor belt hot splicing joints and repair.

Ramimtech conveyor belt jointing cover rubber can be divided in two kinds, usual canvas conveyor belt jointing cover rubber and ST steel cord conveyor belt jointing cover rubber. Thickness are 0.8mm,1mm,2mm,3mm,4mm,5mm and 6mm, also have uncured intermediate rubber and uncured cover rubber, except them, hot vulcanizing solution SK823 also a must in conveyor belt hot splicing joints. Their biggest action will be enhance viscidity and transition function, also promote the results of conveyor belt joints.

One can choose according to the type of conveyor belt, basically, usual canvas conveyor belt joints will choose the thickness of 0.8mm and 1mm uncured intermediate rubber as the pave material, but the thickness 3mm uncured cover rubber as the joint sealed material, ST steel cord conveyor belt jointing will choose according to the whole intensity, such as ST2000N steel cord conveyor belt, above cover rubber whose thickness is 8mm, below cover rubber whose thickness is 6mm, so we will choose related thickness as the pave material.

Differences between uncured intermediate rubber and uncured cover rubber

Their function is different, uncured intermediate rubber is to enhance the bonding strength of conveyor belt vulcanized part, however, uncured cover rubber is to cover on the surface of conveyor belt, mainly for crush resistance and wear resistance, so when we do conveyor belt jointing, we must be clear about this.
