How to Properly Use Conveyor Belt Rubber Strips
In busy conveyor systems, conveyor belts often suffer from long-distance scratches. Traditional hot repairs are complex and time-consuming, no longer meeting the demands of modern industry. Conveyor belt repair strips, as a new type of repair material, offer outstanding wear resistance, strong adhesion, and tear resistance properties, making them ideal for repairing long-distance scratches and various damages.
The semi-vulcanized CN layer of the conveyor belt repair strip has super adhesive properties, allowing for quick repairs, and enabling the production line to resume operation rapidly. We offer two types of repair strips, standard and reinforced, to accommodate different conveyor belt damage conditions. Here's an introduction to how they work and the tools/environment needed for repairs, as well as the operating steps:
How it works: Using a cold-vulcanizing adhesive, attach the repair strip with a semi-vulcanized bonding layer to the conveyor belt surface. They undergo a chemical reaction, quickly curing and achieving a solid bond with the conveyor belt.
Operating Steps
- Preparation: Ensure you have the necessary safety equipment like gloves and safety goggles. The tools and materials required for general operations include conveyor belt repair strips, tungsten carbide buffing disc, angle grinder, cold-vulcanizing adhesive, and cleaner.
- Clean the damaged area: Use a high-powered, low-speed angle grinder and tungsten carbide buffing disc to roughen the conveyor belt repair surface. Ensure that the depth of grinding is greater than the thickness of the repair strip to avoid affecting the cleaning scraper's effectiveness. Use a cleaner to thoroughly clean the conveyor belt repair surface and let it dry.
- Cut the Conveyor Belt Repair Strip: Depending on the size and shape of the damaged area, cut the rubber repair strip into the appropriate shape and size. Ensure that the rubber repair strip is slightly larger than the injured area to fully cover and bond to the conveyor belt.
- Apply cold vulcanizing adhesive: Mix the cold vulcanizing adhesive and hardener evenly and apply an appropriate amount to the entire repair surface of the conveyor belt. Ensure even and complete coverage of the repair area.
- Attach the conveyor belt repair strip: Attach the pre-cut repair strip to the damaged area coated with adhesive. Ensure that the repair strip makes full contact with the belt surface, with no bubbles or loose sections. Use a compacting roller to lightly press the repair strip to ensure a tight fit on the belt.
- Curing and drying: Follow the instructions for the cold-vulcanizing adhesive to allow the repair strip sufficient time to cure and dry (usually several hours). During this natural curing process, avoid any contact with objects or external forces to ensure the stability of the repair area.
- Inspection and testing: After completing the repair, carefully inspect the repair area to ensure that the repair strip is firmly in place and free of any looseness or cracks. Perform necessary tests, such as tension tests or trial runs, to ensure the quality and durability of the repair.
- When multiple repair strips need to be joined for patching, attention should be paid to the overlapping method.
Pre-selection of Conveyor Belt
The selection of conveyor belt needs to consider many factors, mainly: conveyor system's relevant requirements for conveyor belt; terrain environmental conditions and rated requirements for safety; type, shape, particle size, characteristics of conveying materials, whether there is thermal effect and chemical Function; requires maximum bandwidth, working tension and conveying capacity; minimum roller diameter; troughing ability and lateral stiffness; load support; length of curve section and transition section; tensioning method and stroke; receiving point and receiving conditions, and conveyor belt The operating cycle; requirements for impact resistance and tear resistance; joint conditions; and should meet the following requirements:
- For short-distance belt conveyors, polyester fabric core (EP) conveyor belts should be used. Steel cord conveyor belts should be used for belt conveyors with large transport capacity, long transport distance, large lifting height, and high tension.
- The material to be conveyed contains large-sized block materials, and when the direct drop of the receiving point is large, the impact-resistant and tear-resistant conveyor should be selected.
- The maximum number of layers of the layered fabric core conveyor belt should not exceed 6 layers; when the conveyed material has special requirements for the thickness of the conveyor belt, it can be appropriately increased.
- The downhole belt conveyor must be a flame-retardant conveyor belt.
Choice of Covering Layer
The choice of covering layer includes covering material, surface morphology and thickness.
The main components of the covering layer are various rubbers and plastics. In most climates, the rubber can work normally under the condition that the inclination angle is not more than 18°, while the normal operation of the PVC tape is below 12°. PVC is not as good as rubber in resilience, but it has better flame retardancy, discharge properties and cleaning properties. The properties of various rubbers are also very different. For example, natural rubber and styrene-butadiene rubber have good energy absorption and abrasion resistance; ethylene-propylene rubber is particularly heat-resistant; cyanide rubber has good oil resistance; propylene-butyl rubber is both heat-resistant and Resistant to oxidizing chemistry. Therefore, the choice of the type of covering material must be comprehensively considered according to the type of conveying material, operating conditions and working environment.
The increase in the thickness of the covering layer is beneficial to improve the impact resistance and abrasion resistance of the conveyor belt. Especially nowadays cotton canvas belt core has been replaced by synthetic fiber fabric belt core. The performance of the belt core has been greatly improved, while the thickness is relatively thin. In order to improve the overall performance of the conveyor belt, it is necessary to increase the thickness of the covering layer accordingly. Give full play to its advantages and increase the service life of the conveyor belt. However, the lower cover layer is too thick to increase the running resistance of the conveyor belt.
The basis for designing the thickness of the covering layer is the wear speed, material receiving conditions, the heat resistance of the covering layer, impact resistance and the operating cycle of the conveyor belt.
Product Features
Conveyor belt joint Conveyor belt joint type should be selected according to the type of conveyor belt and the characteristics of the belt conveyor; steel cord conveyor belts should use vulcanized joints; multi-layer fabric core conveyor belts should use vulcanized joints; fabric whole-core transportation Adhesive bonding head should be used for the belt, and mechanical joints can also be used.
Conveyor belt vulcanization joint form: layered fabric core conveyor belt should adopt step joint; steel cord conveyor belt can adopt one-level or multi-stage vulcanization joint according to the tensile strength level.
Safety Factor of Conveyor Belt
The importance of reducing the safety factor of conveyor belts and according to the fact that conveyor belts, especially high-strength conveyor belts, account for up to 30% to 50% of the investment in belt conveyors. To choose conveyor belts reasonably and reduce the investment of conveyor belts, an important way is to improve the conveyor belt joint technology to reduce the safety factor. For example, a 20km long conveyor in Australia reduces the safety factor of the steel cord conveyor belt from the usual 6.7 to 5.0, the weight of the conveyor belt is reduced by 14%, the life of the bearing roller is increased by 7%, and the life of the return roller is increased by 40%. The reduction of the conveyor belt tension reduces the corresponding structural investment, and the power consumption is reduced by 4%. The investment and operating costs can be reduced by about 10% within the 20-year service life.
Definition of International Safety Factor
The German Industrial Standard DIN22101-1982 defines the safety factor of the steel cord conveyor belt as the ratio of the tensile strength of the steel cord conveyor belt to the tension of the conveyor belt when the conveyor is running stably, with a minimum of 6.7. In 2002, Germany revised the original 1982 standard, and the new version adopted a brand-new concept and calculation method. The conclusion is that the safety factor of steel cord conveyor belt can be less than 6.7, and the lowest can be 4.5. In the past 10 years, some countries have already broken through the 1982 regulations. The belt conveyors in operation in Germany, Britain, New England, Australia and other countries use 4.5-5.5. According to the research results of foreign institutions such as CDI in the United States, the safety factor of steel cord conveyor belts can be reduced to below 5.5, ranging from 4.5 to 5.0.
