Hot vulcanizing can not only achieve good joint quality, flat and smooth, but also can make the the tensile strength of the belt joint reach 85 % to 90 % of the original conveyor belts. Hot vulcanizing has a simple process and a easy operation, low cost and high quality of belt joints.
The hot vulcanization method is to peel the canvas layer and the rubber layer from a part of the conveyor belts joint into a symmetrical step according to a certain form and angle, apply the vulcanization cement to bond it, and then pass the vulcanization reaction under a certain pressure, temperature and time condition, the raw rubber is turned into vulcanized rubber, and the joint portion is glued together to obtain a higher adhesive strength.
Model DLCBV electric hot vulcanizing machine (following is called "vulcanizer'' for short), has the advantages of small volume, portable, general three-phase power supply, uniform temperature of heating system. Well-distributed pressure (0-2Mpa) supplied by a hydraulic system, equipped with automatic control cabinet and connect the integrated plug with the multi-core cable. Having the vulcanizer, the conveyor belt hot splicing/jointing can be easily done.
It is now used widely for the on-site vulcanizing connection of canvas, nylon, conveyor with steel cable core inside as well as for the connection of rubber belt with special characteristics of anti-corrosion and heat resistant under the circumstance of no explosive gas or any harmful gas to corrode the metal, which is accepted by the metallurgical engineering, mineral production, power station, harbor machinery architectural working or chemical industry etc.
The quality of the belt connection will influence the working efficiency of the rubber belt or the length of life directly, especially for the long distance and high-strength conveyor. Therefore, model DLCBV vulcanizer is the necessary accessories for the rubber belt conveyor equipment.

Maintenance of vulcanizer
Before operating the hot vulcanizing machine, the insulation resistance of heating plates should be checked. If it is too low, the heating plates should be dried by energized until the insulation value is up 50mΩ to meet the operation requirement.
During the operation or transportation, the equipments should be handled lightly.
If carry the field operation task, the waterproof methods should be prepared in advance to avoid the equipments being spoiled.
After usage of the vulcanizer, it should be kept in the storehouse under the condition of less than 85% of relative humidity, and keep air circulation to avoid the erosion by rain or snow. Put the sleepers under the vulcanizer to avoid laying it on the ground directly, which is forbidden.
