Studies of the vulcanization joints of the steel cord conveyor belts

The steel cord conveyors have been used in mines, power plants, harbors and some other enterprises. This kind of conveyors with high_strength belts can meet the need of the large quantity and the long distance transportation. The vulcanization joints of the steel cord conveyor belt has played an important role in the safety transportation. Besides, it has the advantage of lower cost, fewer breakdowns and continuous transportation. The manufacture of the steel cord belt ensure that its service life is 4 years (there is no national standards). After the further studies of joints form and the vulcanization process, it has showed that the joint strength is more than 90 per cent and its service life will be 6 years. Analysis and studies of the process and the parameters of the vulcanization have been presented, and some directions concerning the operation have been stated.
