Laboratory Two Roll Mill – Automatic Rollover PLC Program Control MMS-401C

A Two Roll Mill, commonly employed in the plastics and rubber industries, is a machinery used for compounding, processing, and shaping high-molecular-weight materials like rubber and plastics.

Two roll rubber mill typically consists of two parallel rotating cylinders that facilitate mixing, processing, and contour adjustments of the materials through a combination of compression and rotation.

Two roller mill harnesses the squeezing and rotational forces generated by the cylinders to effectively homogenize and refine the materials.

two roll mill for rubber compounding plays a pivotal role in the manufacturing and refining processes of polymer-based materials.
