Description
Laboratory Rubber Mixing Machine, also known as open double-roll refiners, are specialized in mixing rubber compounds in the rubber and plastics processing industry ,it is enginered to provide unmatched performance for masticating and kneading natural rubber, synthetic rubber, EVA, or PVC pellets with various chemical materials, This two roll mill machine is mainly used for plastic, hot mill, and mixing mill of natural and synthetic rubber for rubber product factory, specially used for learning institutes and laboratories with smaller batch size preferences.
This two rolls rubber mixing machine mainly comprise of base, frame, rollers, transmission system, lubrication device, heating and cooling device, roll gap adjustment device, safety braking device, motor, speed reducer etc. The speed of rollers is controlled and adjusted by reducer driven by transmission , which is conducted by the main motor.
We have two opition for you ,either two roller by one transmission or each transmission control the speed for each roller respectively .
Our PVC polymer open mixing mill equipment can be customized in different capacity and confirgurations as per your specific needs . It is widely used for small-batch formula testing ,contrast ,and quality control in polymer material research and development laboratories .

Steps in the Rubber Mixing Process
1. Introduction of the Polymer
The rubber mixing process begin from the introduction of the polymer, the basic structure of rubber compounding. The choice of polymer material contribute to the foundation for the material’s performance and dictates its inherent characteristics.
2. Sequenced Addition of Ingredients
While the polymer typically has the largest impact on the characteristics, additional ingredients are added would determine its features ,including curing and processing performance, consideration of production cost , hue designation, anti-degradation, and many other . This may be fillers, plasticizers, curing agents, accelerators, etc.
3. Achieving Homogeneity in the Compound
The ultimate goal is to achieve thorough homogeneity. Through well-mixed and blended of all ingredients ,it would create a uniform and consistent rubber compound. A homogeneous rubber compound ensures uniform characteristics throughout production processing, curing and the final application of finished rubber goods. This is achieved by carefully adjusting the several key mixing parameters according to the compound requirements while carefully considering chemical interactions of ingredients. Each rubber compound performs and reacts differently to the process. Therefore , to create a ideal mixture ,it requires an experienced operator execute on each compound’s detailed and exact mixing procedure .
