For preparing test sample from two or more materials, they have to be mixed homogeneously. The Two Roll Mill with its two heated rollers, rotating in different directions, at slightly different speeds is an ideal machine for such a work. The test samples can then be obtained from the sheet by using Hydraulic Hot Press, Dumb-bell Dies etc.

Two Roll Mill is available in two models one for PVC Compounds (Model SSI-511A) and other for PVC/Rubber Compounds with heavy duty motor & water cooling arrangement (Model SSI-511B).
The Instrument consists of following:

       Two rollers mounted on a sturdy frame, rotating in different direction at slightly different speeds. Normal roller Size 6 dia, 12 Length.

       Two Energy Regulators for heating control one for each roller. Heating by especially designed U shaped heaters.

       One 440 V 3 phase. Motor with gear assembly for rotating the rollers.

       Water cooling arrangement (in the Model SSI-511B for Rubbers). Separate water tank and motor is provided for the purpose.
