"MARSHAL" Two Roll Mill also known as Twin roll mill or Rubber mixing mill is a worldwide accepted as lab compounding machine for lab evaluation of pigment and masterbatch. This Lab Two roll mill is also used for uniform pigment & polymer mastication. "MARSHAL" Two roll mill is normally used in combination with "MARSHAL" Lab Hydraulic Press. Between two electronically heated rollers with precise nip gap, the compound is masticated for controlled time at measured friction ratio. The results are compared after getting the compression moulded uniform chips from "MARSHAL" Lab Hot Hydraulic Press.
- Uniform temperature distribution across the rollers
- Reproducibility of results
- Rapid cooling of rollers by water circulation in the roller core for frequent polymer change.
- Any polymer like LDPE, HDPE, PP, PVC, PS, ABS, HIPS, Natural Rubber, EVA etc. can be tested
- Uniquely designed doctor’s blade for ease in scrapping the melt
- Available roller size: Diameter 110mm/150mm
- Individual adjustable roller speed with digital RPM read out to set different friction ratios
- Incorporated with additional safety features like Knee operated reversible emergency switch at both the sides, hand operated roller safety switch and emergency push button on panel
- Digital nip gap read out for both the end of rollers
- Control options available like HMI touch screen with PLC control and digital display by PID controls
