What should be done if the conveyor belt and drum are still prone to slipping?

Making roller wrap is a necessary treatment for rollers in conveyor systems, which is used to increase the friction between the rollers and the conveyor belt, improve power output efficiency, protect the rollers, and extend their service life. But what should be done if the conveyor belt and drum are still prone to slipping after being coated with glue?

The drum and conveyor belt that have been coated with glue are prone to slipping, which needs to be analyzed from the following aspects:

Whether the specifications and forms of the rubber plates used for the drum, especially the drive drum, are suitable for environmental requirements;

Whether the aging performance of the rubber sheet has decreased;

Whether the rubber plate is excessively worn.

The driving drum requires higher friction between the conveyor belt and the drum than the driven drum, so the rubber sheet used for driving the drum must have patterns. Diamond and herringbone patterns can effectively improve the friction between the driving drum and the conveyor belt, and the grooves between the patterns can also serve as channels for drainage, sludge discharge, and adhesive material discharge, greatly reducing the impact of the production environment on the friction between the rubber sheet and the conveyor belt.

For conveying work with high tension on the conveyor belt, strong material wear, and high water and mud content, ceramic rubber plates with stronger adaptability to harsh environments are also needed. The grooves between ceramic blocks are deeper, and the drainage and mud discharge effects are stronger and more wear-resistant. The friction force decreases less due to environmental factors, and can always maintain a high friction force, reducing conveyor belt slippage. Moreover, the service life in high wear environments can reach 8-10 times that of ordinary wear-resistant rubber plates

The surface of the rubber plate is continuously contracted and stretched by rubber to remove adhesive substances, reducing the sliding friction caused by foreign objects on the friction surface, that is, reducing belt slippage. When the rubber ages and becomes hard, and cannot self clean the surface by squeezing, slippage between the conveyor belt and the drum is inevitable. The rubber plate of hot vulcanized drum casting rubber has a high sulfur content and is prone to aging. In addition to the inconvenience of transporting hot casting rubber, this is also one of the important reasons why hot casting rubber is gradually replaced.

If the rubber plate is excessively worn, it is necessary to replace the rubber plate and remake the roller coating.

It is recommended to use cold vulcanized roller wrap for making roller wrap. The cold vulcanized roller wrap made of German imported cold vulcanized adhesive SK313 and RIT wear-resistant rubber plate is not only fast in production, but also can be completed within 1-2 hours and restored to operation within 8-12 hours. The adhesive strength and wear resistance of the rubber plate are higher, the friction force is greater, and the service life is 2-4 times that of similar domestic products.
