Process requirements for compounding conveyor belt rubber

In order to ensure proper compaction of the rubber discharged from the mixer, an open rubber mixing machine must be used in conjunction with the internal mixer as specified by the code. Depending on the type of internal mixer employed, the properties of the final mixed rubber may vary. Therefore, it is essential to follow standardized procedures to maintain consistency and quality. The process for preparing the rubber compound in conveyor belt manufacturing involves several key steps, including weighing, mixing, and vulcanization. The raw materials, such as natural or synthetic rubber and carbon black, must be accurately measured to the nearest gram. This precision is crucial to achieving consistent performance in the final product. Regarding the mixing equipment, the open-type rubber mixing machine must meet specific standards. For internal mixers, it is necessary to have a temperature monitoring system, a timing device, and a power or torque recording system that can independently display and record data during the mixing process. These systems help ensure accurate control over the mixing conditions, which directly affect the quality of the compound. In addition, the internal mixer should be equipped with 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 uniform mixing and preventing material degradation. The internal mixer should also include adequate exhaust systems and safety mechanisms to protect both operators and equipment. To achieve optimal compaction of the rubber after mixing, the open rubber mixing machine must be available alongside the internal mixer. While different types of internal mixers can be used, it is important to note that they may result in variations in the final rubber properties. Therefore, careful calibration and adjustment of the mixing procedure are necessary to obtain comparable results. When conducting tests, the adjustment of the mixing process should be agreed upon by all relevant parties. If the roller gap exceeds the standard specifications, maintenance or overhaul is required to prevent any negative impact on the mixing quality. During the mixing process, the rubber compound is typically placed on the front roller of the mixer. Throughout this phase, the roller temperature must remain within the designated range to ensure proper mixing and avoid overheating or under-processing.
