185KW Energy Saving Two Roll Mill Machine Open Mixing Mill Φ660x2030mm For Rubber

Description:

Rubber mixing mill

1.The rolls are made of chilled cast iron with spun casting.The roll face is hard and anti-wear.The internal cavity is processed to make temperature well proportioned on the roll surface.

2.The machine is equipped with an overload protection device to prevent the major components frombeing damaged due to overloading.

3.The machine is also equipped with an emergency device.When an emergent accident happens,just draw the pull rod,and the machine will stop immediately.it is safe and reliable

4.The transimission system adopts a ZQ planetary gear reducer,which has a compacted structure with higher transmission efficiency,lower noise and longer service life.

5.The base frame is a complete framework,which is convenient for installation.

Applications:

Two rollers open rubber mixing mill main used in rubber product factory: Natural rubber refining, raw rubber and compound mixing. Rubber beating mixing and rubber tab letting.
This machine is double roller opening to be used for rubber or plastic mixing. It consists of seat, Frame, Rubber, Driving device, Lubricator and cooler, range adjusting device of roller. Safety brake. Motor and reducer, etc. The roller is made from safety cooled and hard cast iron, smooth surface is polished in term of different case. Saturated steam and cooling water can be inputted in the empty roller to adjust temperature of roller. Colloidal particles are drawn into the gap of the two rollers which make relative rotation in different velocity to mix rubber, into further rubber sheet.
