Open Rubber Mixing Mill Lab Two Roll Mill for Rubber Compounding Plastic Mixing

HZ‑7015 Open Rubber Mixing Mill (two‑roll open mill) is designed for mixing and processing polymer materials including rubber, silicone, PVC and color masterbatch. It mixes raw rubber and compounding additives to achieve target color and physical performance for rubber formulation research.

Equipped with precision heated/cooled roller assembly, roller surface maintains uniform temperature without peeling. Adjustable roller gap enables controlled sample sheet thickness. Multiple built‑in safety protection devices guarantee safe daily operation.


HZ‑7015 series provides two working types for selection:

  • HZ‑7015A: Electric heating type

  • HZ‑7015B: Water‑cooled type (standard for rubber mixing)

Both versions share identical roller mechanical structure, safety emergency‑stop system and frequency‑conversion speed regulation. SUS304 stainless steel picking device is standard fitted for collecting finished rubber sheets. Roller gap adjustable from 0.1‑10 mm, digital display readout for gap value, convenient for rubber thickness setting during compounding test.





This machine suitable for plastic industry polymer material mixing and processing such as, PVC, color master batch. Making the raw material and compound mixing, and achieve the required color and quality. The machine adopts special heated mold, roll surface temperature uniformity, never take off a layer, sample thickness can be mixed, the machine safety protection device, convenience to use.
