50HZ Electric PVC Open Mill / Industrial Mixing mill Equipment

Product Specification

50HZ Electric PVC Open Mixing Mill Industrial Mixing Equipment

Descrition:

For masticating and kneading natural rubber, synthetic rubber, EVA or PVC
pellets with various kinds chemical material and warming the cold material
which shall be supplied to the calendar, embossing calender or hot presses.
This machine is used for mixing and kneading raw rubber, synthetic rubber,
thermoplastics or EVA with chemicals into even materials. The even materials can be fed to calender, hot presses or other processing machinery for making rubber or plastic products.

Rolls:
Manufactured from chilled cast iron, inside rolls are cooled by water or
heated by steam

Frames:
Manufactured from welded steel plates or high tensile cast iron for maximum rigidity

Bed:
One piece construction of welded steel plate or cast iron provides maximum
stability

Bushing:
1) An oil sealed type bushing, the bushing housing is manufactured from
cast iron, and the inside diameter is fitted with high lead bronze.
Designed with water circulation circuit for water cooling, reducing heat
generated between the roll neck and the bushing
2) The bearing type bushing is constructed of cast iron housing and high
strength bearing at inside diameter

Bushing lubrication:
Employs automatic circulated lubrication system

Roll gap adjustment:
1) Manual gap adjustment is standard
2) Powered gap adjustment is optional

Reduction gear box:
Three-step totally enclosed gear reducer is driven by bevel gear. Gears are lubricated by self splash lubrications system

Applications:

 Two roll mill machine is mainly used for plasticating and mixing of rubber or plastics, warming and sheeting rubber compound, cracking and refining of reclaimed rubber.

Option

Mixing mill working principle of the equipment is the main working part two speed ranging from relative rotation of the hollow roller. When added to the two rubber roller in the roller extrusion after above at the same time under the action of friction and adhesion force, form the end of the wedge strip, Under the action of roller by the strong crush, cut and tear strip, accompanied by chemical action, So repeatedly, finally complete the new practice, thermal refining and mixing and tablet.
