Process requirements for compounding conveyor belt rubber

To ensure the rubber discharged from the mixer is properly compacted, an open-type rubber mixing machine as specified in the code must be used simultaneously. Depending on the type of internal mixer employed, the properties of the final mixed rubber may vary. Therefore, it's essential to follow standardized procedures and ensure consistency throughout the process. The steps involved in the compound preparation for conveyor belt manufacturing—such as mixing, vulcanization, and compounding—are crucial for achieving high-quality results. First and foremost, accurate weighing of raw rubber and carbon black is required, with measurements precise to the nearest gram. This level of accuracy ensures that the mixture remains consistent and meets quality standards. Regarding the mixing equipment, the open-type rubber mixing machine must meet specific requirements. For internal mixers, it should be equipped with a temperature monitoring system, a timing device, and a power or torque recording system. These systems are necessary to track and record critical parameters such as temperature, time, and energy consumption during the mixing process. Additionally, the internal mixer must have an effective heating and cooling system for the nylon conveyor belt to maintain the rotor and chamber wall temperatures within acceptable limits. Proper temperature control is vital for ensuring uniform mixing and preventing material degradation. The mixer should also include appropriate exhaust systems and safety features to protect both the operators and the equipment. To ensure proper compaction of the rubber after mixing, the open-type machine specified by the code must be used alongside the internal mixer. While different types of internal mixers can be used, they may lead to variations in the final product’s properties. However, if the mixing procedure is carefully adjusted, comparable results can be achieved. Any adjustments should be agreed upon by all relevant parties before testing begins. If the roller gap exceeds the standard, maintenance or overhaul is necessary to avoid compromising the mixing quality. During the mixing process, the rubber compound is evenly distributed on the front roller by the conveyor belt manufacturer. Throughout this stage, the roller temperature is continuously monitored to remain within the specified range, ensuring optimal mixing conditions.
