Laboratory Three Roller Calendar

This small lab three roller calendar is a miniature rolling units, with low energy consumption and small amount of raw materials. It is suitable for laboratory use and small-scale production. three roller calendar

Main Features of the Three Roller Calendar


  • Linear slide guide for the rolls, compacting pneumatic cylinder to adjust roll gap as to guarantee the accuracy of sheet thickness
  • Super mirror surface roll and, dual-loop temperature control systems for precise control of the roller temperature, ideal for the application of crystalline material
  • Variable motor speed controller to adapt roll speed with winder speed and extrusion speed
  • Pull activated safety cable switches for switching off from any direction

Typical Applications of the Three Roller Calendar


  • New product development
  • Testing dispersion of different filling materials
  • Testing dispersion of masterbatch
  • Optimization of production processes
  • Quality control
