MechanismTorque Limiter
- Overload protection device
-
While the machine is in operation, it protects the machine
in the event of an overload or unexpected problem.
Torque Specification
- 01Torque Specification (Nm/Cm3)
- 02Torque per shaft (Nm)
- 03Center Distance (CL(cm))
Torque specification is a numerical value that single-shaft torque value divided by the cube of distance between shafts center. (Specific Torque = Torque rating for shaft (Nm)/( Cm3)
- When compounding polymer, energy consumption by material is different.
- When choosing the right equipment for compounding polymer, the size of screw, cross-ratios (Do/Di) and torque specification are the major considerations.
- Generally SM Platek extruder torque specification was 11.3 Nm/Cm3 but we developed 15.3 Nm/Cm3 to let our customers have more selection.
