Conveyor systems are used in varied industries but its use is extensive in the quarries and mines. The operative efficiency improves with the use of conveyor belts. They are considered to be the first checkpoints when it comes to optimizing productivity. Splice is a critical area in the conveyor system. There are two types of splicing method, mechanical and vulcanized splicing. The former joins the ends using metal hinges and the latter through heat or chemicals. Each method has its own benefits and disadvantages. While taking a splicing decision it is important to consider the benefits along with other factors like
• Impact on the environment
• Time span
• Cost constraints
• Downtime
Understanding Conveyor Belt Vulcanizing
The process is complex and has to be done by experts. Vulcanizing offers smooth splice with little snagging risk. The method offers minimal risk of harmful wear and tearing of the belt. There are different types of splice like finger splices, stepped splices and overlap splices. The two vulcanizing process include hot and cold methods. Each process is unique and requires specialized tools and knowledge of rubber bonding procedures.
Whether for hot or cold vulcanization, the belt has to be disassembled and the belt ends have to be prepared as per the splicing recommendation. Belt preparation is s crucial part of the vulcanization process and it ensures the finished splice holds to the tensile ratings.
In the case of hot vulcanization process, the splice is heated and cured under pressure using the vulcanizing press. The could take several hours. Incase the belt is re-tensioned and used before the bonding of the splice and cooled completely, it could be ineffective and can tear apart leading to more downtime.
On the contrary cold vulcanizing does not use vulcanizing press but uses bonding agent that leads to chemical reaction attaching the belt ends.
