Key Features of Laboratory Type Two Roll Mixing Mill
- Built-in Driving Unit, less space requirement,
- Available with 6 pole electric motor using circular type Reducer gives lowest noise level.
- Rolls are hard chrome plated grounds and polished, surface hardness 60HRC or above [hardness depth approx. 1.5mm] roughness height of 0.5cm.
- Roll Bearings are in the form of double row taper self aligning Roller Bearings.
- The bearings are lubricated with Auto-lubrication system.
- Specially produced Roll Mill prevents the two rolls from touching each other during operation.
- An Emergency Safety Device by a knee pedal to facilitate automatic stopping the machine and to enable the rolls to be reversed about 11A of the circumferences.
- Material guide plate produced of Teflon, heat and acid-resistant, no staining and will not do harm to the rolls as comparing to with conventional bronze guide bars.
- Maximum working temperature up to 240 degree eel. [Electrical heating system higher on request]. Most precise temperature control thanks to specialised heating systems. For electric heating, most precise automatic temperature controller and specially designed temperature sensors are used with accurate indication of working temperature which allow tolerance of ± 2 degree Celsius.
- Surface temperature deviations are ± 2 degree cel.
