Explain in detail the preventive measures for PVG flame retardant conveyor belts after they encounter edge wear

Basic Description

Sometimes after the PVG flame-retardant conveyor belt has been used for a period of time, some users will find that the conveyor belt has edge wear. So what is the reason for the edge wear on the PVG flame-retardant conveyor belt? In response to this situation, let us introduce the reasons for the wear of the edges of the PVG flame-retardant conveyor belt and the methods to reduce the wear of the edges.

The edge wear of PVG flame-retardant conveyor belt is mainly caused by the friction and wear between the belt edge and the frame when the conveyor belt deviates. The conveyor belt should run on the center line of the roller group, but the defects caused by the manufacture, installation, and use of the conveyor , The conveyor belt will often deviate from the center line. Generally, PVG flame-retardant conveyor belts allow 5% deviation in the width direction. When the deviation is too large, the conveyor belt will contact the roller bracket and the frame and cause the edge rubber to wear. When the deviation is severe, it may even cause Conveyor belt flanging, such as the radial travel screw head of the roller, the cleaner block and other raised parts, or the frame gap is too small, it is easy to cause the conveyor belt to tear, partial peeling of the covering rubber and scratches.

Through the analysis of the wear factors of PVG flame-retardant conveyor belts, in the design of belt conveyors, corresponding preventive measures are taken to extend the life of the conveyor belt. The design is usually optimized from the following five aspects to reduce the conveyor belt's Wear:

1. Reasonably choose conveyor belt;

2. Reduce the wear of conveyor components to the conveyor belt;

3. The structure of the feeding device is optimized;

4. Reduce the impact of the material receiving process on the conveyor belt;

5. Adopt electromechanical protection device.

Compared with ordinary conveyor belts, PVG flame-retardant conveyor belts have the advantages of better performance, longer service life, more dense belt body, less water ingress, and rot resistance. The flat vulcanization process is adopted. The specific process is that the whole belt core is impregnated with PVG plastisol after initial molding in the oven, and the lower cover rubber is added, and the flat vulcanizing machine is heated and pressurized. PVG flame-retardant conveyor belt is composed of core rubber, steel wire rope, covering layer and edge rubber. The covering rubber has good abrasion resistance, high tear strength, and excellent safety performance such as flame retardant and antistatic.
