Two Roll Mills
Rotomill 15/24 - Variable Speed Two-Roll Mill
 The ruggedly built Rotomill 15/24 is an all-electric variable speed two-roll mill. The Rotomill has an adjustable nip and accomodates a wide range of plastic materials. This mill uses individually driven, chrome-plated carbon steel rolls – cored for heating and cooling. Heavy duty roller bearings and other production-oriented construction considerations ensure this machine's extreme durability.
Features:
- All-electric machine
- Small footprint
- Variable speed
- Extremely durable
- Wide materials processing range
- Cored rolls
Rotomill Benchtop 75/150 and Rotomill Production 150/300
 The ruggedly built, small footprint, ROTOMILLS are all electric variable speed two roll mills with adjustable nip and shear capability.
Suitable for a wide range of plastic and rubber materials the mills use individually driven carbon steel rolls cored for heating and cooling driven by enclosed AC flux vector constant torque inverter drive motors. Each rotor is independently driven with heavy-duty reduction gearboxes and duplex chain drives.
Moving components are fully guarded and include electric interlocks.
Roll speeds of between 10 and 45 rpm.
These machines are 415v, 3 phase units.
