Description:
 
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
