What is a conveyor belt vulcanizing press?

A vulcanizing press is designed for repairing damaged or worn rubber conveyor belts, especially in on-site environments. These splicing machines are compact, easy to operate, and ideal for addressing belt damage quickly and effectively.

Why should I use a vulcanizing press for belt repair?

In industrial settings, conveyor belts are essential for material handling, and joint wear is inevitable. Replacing an entire belt is costly and time-consuming. A vulcanizing press allows for on-site repair, significantly reducing both material costs and downtime. Vulcanization is generally preferred for belt splicing due to its superior strength, longer service life, and cleaner operation.

We're operating a coal mine where belts are frequently cut or gouged by slag and debris. What should we do?

For coal mines using PVG belts, a vulcanizing press is the ideal solution. Our vulcanizing presses offer adjustable temperature control from 0–200°C, meeting the typical 130°C curing requirement for PVG belts. After vulcanization, the belt naturally cools to below 70°C within 15–20 minutes greatly minimizing production delays. The vulcanizing machine is durable and efficient, making it a perfect fit for the demands of coal mining.

Our conveyor belts are thick and heavy due to the high load of our materials. Will a vulcanizing press still work?

Yes. We recommend using a hydraulic vulcanizing press. Our hydraulic models offer surface pressure up to 125 N/cm², which improves the bonding strength and static stiffness of the belt after vulcanization. It also reduces the release of volatiles during high-temperature curing, resulting in a stronger, longer-lasting splice.

We’re setting up a new mining operation and need to vulcanize a large number of new rubber belts. What’s the best solution?

The KR-200 stationary vulcanizing press is ideal for high-volume belt installation. It’s an upgraded version of the standard press, featuring higher efficiency and added safety mechanisms, such as an automatic safety-lock lifting system and built-in rollers for mobility. This model is specifically designed for intensive splicing tasks in mining operations.
