Description

Instrument Principle

Uniform mixing of two or more components to make a homogeneous mixture is vital to make samples for testing. The Two Roll Mill with its two heated rollers, rotating in opposite directions, at slightly different speeds is an ideal machine for such a work.

 
The final test samples can then be obtained from the sheet by using Hydraulic Hot Press, Dumb-bell Dies etc.
 
Two Roll Mill is available in various models for specific customer requirement. Various Models are
 
  1. For PVC (With Heating only)
  2. For Rubber (with Water Cooling only)
  3. For PVC and Rubber (with heating and water cooling)
  4. Rollers with Variable RPM
  5. Rollers with Variable RPM and Friction Ratio

Instrument

The Instrument consists of following:

       Two rollers mounted on a sturdy frame, rotating in opposite opposite  at slightly different speeds.

       Roller Size: 6″ dia, 12″ Length.

       Temperature Control : Using two Energy Regulators one for each roller.

       Heater: Heating by especially designed U shaped heaters.

       Motor: 3 Hp, 440 VAC,  3 phase.

       Gear Assembly : to drive the rollers in opposite directions. 

       Control: Forward Reverse Switch and power cord.

       Spatula for mixing the compound.

       Emergency Switch to shut off motor in case of emergency

 

This Model is suitable for PVC and allied material which require heating for melting and mixing. Not suitable for rubber materials which generates heat during mixing.
