2-15mm Roller Space Composite Rubber Mixing Machine

1. Structure and operation:
- Simple structure: Compared with other rubber processing equipment, the structure of the open mill is more intuitive and uncomplicated. It is mainly composed of basic components such as rollers, transmission devices, bases, heating and cooling systems, etc. It is easy to manufacture and the cost is relatively low. This makes the purchase cost of the equipment more acceptable to some small rubber processing companies or companies with limited budgets.
- Easy to master the operation: The operation method is relatively easy to understand and master. After a certain amount of training, operators can quickly get started. Operators can flexibly control the rubber mixing process by manually adjusting parameters such as roller spacing and roller speed according to actual production needs, which is very suitable for some small-scale and diversified production companies.
2. Rubber mixing effect:
- Good mixing effect: The two rollers of the open mill rotate relative to each other at different speeds, which produce strong extrusion and shearing effects on the rubber material, which can break the macromolecular chains inside the rubber and allow the various ingredients in the formula to be fully mixed and evenly mixed, thereby achieving a good mixing effect. For some rubber products that require high mixing quality, such as high-end rubber seals, special rubber tubes, etc., the open mill can meet their production requirements.
- Good plasticizing quality: It has advantages in plasticizing rubber. It can use mechanical force to break the rubber molecular chain at low temperature to obtain plasticized rubber with good plasticity and small shrinkage. This low-temperature plasticizing method can better retain the original properties of rubber and make rubber products have better physical and mechanical properties.
3. Production process control:
- Easy to observe and adjust: The open structure design allows operators to directly observe the processing of the rubber between the rollers, and can understand the mixing state, temperature changes, plasticity changes, etc. of the rubber in real time, so as to find problems in time and make adjustments. For example, when it is found that the rubber is mixed unevenly, measures such as changing the roller speed, adjusting the roller spacing, and increasing the mixing time can be taken in time to improve the mixing effect.
- Flexible temperature control: The roller is hollow, and cold water or steam can be passed in to adjust the roller temperature, thereby controlling the temperature of the rubber. This enables the open mill to adapt to the processing requirements of different rubber materials. For some temperature-sensitive rubber materials, the temperature can be accurately controlled to avoid affecting the quality of the rubber due to excessively high or low temperatures.
4. Applicability:
- Applicable to a variety of materials: It can be applied to the processing of a variety of rubber materials. Whether it is natural rubber or synthetic rubber, it can be effectively plasticized and mixed on the open mill. At the same time, for rubber materials with different formulations, the open mill can also achieve good processing results by adjusting process parameters.
- Can handle special rubber: In some special cases, such as mixing heat-sensitive rubber or materials that need to avoid early vulcanization, the open mill is more suitable. Because of its open structure and flexible temperature control method, it can better meet the processing requirements of these special rubbers.
5. Maintenance and cleaning:
- Easy maintenance: The equipment has a simple structure and is relatively easy to disassemble and repair. When the equipment fails, maintenance personnel can quickly disassemble, repair and replace parts of the equipment, reduce equipment downtime, and improve production efficiency.
- Easy to clean: The open structure makes it easy to clean the rubber residue inside the equipment, avoiding the accumulation and deterioration of the rubber inside the equipment, thus ensuring the quality of the rubber for the next production.
