In the field of rubber and polymer materials, laboratory mixing mills play a critical role in formulating, testing, and developing rubber compounds. These compact but very powerful lab scale two roll mills machinerys are specially designed to simulate the mixing process of full-scale production mills—on a much smaller and more precise scale. Whether you are in R&D, quality control, or small-batch production, a rubber compound laboratory mixing mill for rubber compounding is a vital tool for your workflow.
What Is a Rubber Compound Laboratory Mixing Mill?
A lab mixing mill is a bench-scale two-roll mill machine for silicone, EPDM, SBR, and TPR, designed to mix raw rubber with additives like carbon black, plasticizers, accelerators, and fillers. The rubber compounding machinery equipment consists of two horizontally placed cylindrical rollers ,they are usually made of chilled cast iron or stainless steel material ,which depending on your material and specific needs . When polymer mixing equipment starts , these two cylinder rolls rotate in opposite directions at different speeds,which generate a strong force ,to shear and blend rubber materials evenly.
Key Features and Benefits of Two Roll Mixing Mill
1. Precise Mixing Control
The lab two roll mill offer high control over mixing parameters such as roll temperature, friction ratio, rotating speed, roll width, roll gap, temperature control and mixing time etc .These parameters can be adjusted by researchers as per compound formulation and replicate production conditions for accurate testing ,so that achieve specific material properties and processing requirements.
2. Compact and Cost-Effective
Different from large capacity industrial internal mixer mill machine , the compact lab scale mixing mill consume less space and power ,which is more , it is easier and more convenient to operate, which make these lab scale two roll mill equipment ideal for university labs, material testing centers, and small-scale manufacturers.
3. Roll Heating & Cooling System
Modern laboratory mill polymer mixing equipment are typically equipped with temperature-controlled rollers ( the lab roll mill are heated via electrical elements or oil circulation; cooling via water), which help maintain stable compound temperatures during the mixing process—critical for heat-sensitive elastomers.
4. Stock Blender (Optional)
For large scale lab rubber processing machine , in order to mix and knead the compound material evenly and fully , the two roll rubber mill machine can be equipped with a stock blender . With the stock blend ,it helps automate the folding of rubber sheets during mixing, improve uniformity and operator safety, and reduce manual workload.
5. Data Logging & PLC Controls
Advanced lab two roll mill for silicone, EPDM, SBR, and TPR can come with PLC touchscreen control panels . It can allow to save recipe , log temperature and time-stamped operational data automatically ,therefore help to production repeatability and quality control.
