The Yokohama Rubber Co., Ltd., announced that from October it began marketing its new “High-Heat Resistant MJ Fabric Belt” for use with conveyor belts featuring mechanical joints (MJ).
The new product provides heat resistance at very high temperatures, a crucial quality for conveyor belts with mechanical joint. The new belt is expected to shorten the time required to splice the belts, reduce required staff numbers, and contribute to cost reductions. Yokohama Rubber developed the new product to meet the substantial need for conveyor belts with mechanical joint in overseas markets, especially in North America, and to build a more global business.
Yokohama Rubber’s high-heat resistant conveyor belts have been used to transport extremely hot materials, such as coke and sintered products, which can reach temperatures as high as 400°C. To date, Yokohama Rubber has promoted the use of hot vulcanization that place a small burden on operating machinery and on splice durability. However, this requires shutting down the conveyor line for long periods of time to replace the conveyor belt. On the other hand, the use of mechanical joints shortens the splice time but subjects the conveyor belt to shearing by the mechanical joint at the splicing area. To overcome this problem, Yokohama Rubber made technical improvements to the carcass fabric, which has a major impact on the strength and performance of the conveyor belt.
