The Main Features of Rubber Calenders
The rubber calender is a machine used in the production of various rubber products. Its main features are:
- Working Principle: The rubber material is stretched and thinned by the pressure applied through the relative rotation of multiple rollers, resulting in uniform thickness control.
- Structural Features: The roller is a key component, usually made of high-quality steel with high hardness, strength, good thermal conductivity, and high surface accuracy to ensure the quality of the calendered products. It is also equipped with a complete transmission system that can accurately control the roller speed and achieve different calendering speeds and speed ratios.
- There is a reliable spacing device that can flexibly adjust the spacing between rollers to adapt to the calendering of rubber materials of different thicknesses.
- Precision Control: The rubber calender can accurately control the thickness, width, and other dimensional parameters of rubber sheets or profiles. The thickness tolerance can be controlled within a small range, such as about ±0.02mm.
- Temperature Regulation: Most rubber calenders have roller heating or cooling functions. The temperature control system can keep the roller at a suitable working temperature, generally between 50℃ and 150℃, which is conducive to the plasticization and molding of rubber.
- Production Efficiency: The rubber calender has high production efficiency and can operate continuously. It can quickly calender a large amount of rubber raw materials into products of required specifications. The hourly output varies according to the machine model and process. Small ones may be several tons per hour, and large industrial ones can reach tens of tons.
- Scope of Application: The rubber calender is widely used in the production of various rubber products, such as tires, conveyor belts, rubber sheets, seals, etc. Raw material processing links.

The Operation Process of Rubber Calender
The operation process of the rubber calender involves preparation before starting, start-up operation, calendering process operation, and shutdown operation. Here's a detailed breakdown of the process:
Preparation before Starting
Before starting the calender, some essential preparations must be taken:
- Equipment inspection:
- Check the various components of the calender, such as rollers, transmission systems, spacing devices, temperature control systems, etc. Ensure that the components are well-connected, and there is no looseness or damage.
- Check the surface of the roller and clean it if there is debris or damage.
- Material preparation:
- Prepare the rubber raw materials to ensure that their formula is accurate and mixing is uniform.
- Prepare auxiliary materials such as additives and fillers required for production.
- Parameter setting:
- Set roller speed, roller spacing, working temperature and other parameters in the control system.
- For example, when producing rubber sheets, the roller spacing needs to be set, and the appropriate working temperature needs to be determined for different types of rubber.
Start-up Operation
The start-up operation involves:
- Starting the transmission system: This is done to ensure that the roller starts to rotate slowly. It is essential to observe whether the roller rotates smoothly and detect any abnormal sounds or vibrations.
- Preheating the roller: The temperature control system is started to preheat the roller according to the set working temperature. During the preheating process, the temperature changes are monitored to ensure that the temperature rise is uniform and stable.
Calendering Process Operation
The main operations to be carried out during the calendering process are:
- Feeding: Prepared rubber raw materials are fed slowly and evenly into the feed port between the rollers. The feeding speed should be moderate to avoid any issues.
- Calendering adjustment:
- Check the molding of rubber products, observe the flow of rubber between the rollers and adjust the speed ratio of rollers, and other necessary parameters.
- Continuously check the quality of the calendered rubber products, including appearance, and dimensional accuracy, among others.
Shutdown Operation
The shutdown operation process entails:
- Stop feeding: When current production tasks are completed or production needs to be suspended, first stop feeding the rollers, and let the remaining rubbers be calendered until all rollers are sent out.
- Cooling Roller: Turn off the heating function of the temperature control system and allow the roller to gradually cool down; the cooling function can be turned on as necessary.
- Stop the transmission system: After the roller has cooled down and the rubber has been fully delivered, stop the transmission system of the calender to stop the roller from rotating.
- Equipment cleaning: Clean the calender thoroughly, remove the rubber, and other debris remaining on the roller surface, feed port, discharge port, and other parts of the equipment in preparation for the next start-up.
