Triple Roller Mill – Principle, Construction, Diagram, Working, Applications

triple roller mill

Triple Roller Mill is one of the equipment used for mixing purposes in various industries. It is also known as three roll mill.

Principle of Triple Roller Mill

A three roll mill or triple roller mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and at different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.
Construction of Triple Roller Mill

Triple roller mill consists of three rollers which are made up of hard abrasion-resistant material.
These rollers are arranged in such a way that they come very close to each other.
These rollers are rotated at different rates of speed. The material coming between the rollers is crushed depending on the gap between them and the difference in rates of movement of the two surfaces.

Design Highlights
  • Scraper System with interchangeable blades
  • Single or dual roller speed
  • Frequency Inverter for Speed Control
  • Heating & Cooling System for the Rollers
  • Explosion Proofing electrical
  • Automatic Product Dispenser
  • Solvent Dispensers
  • Stainless steel hopper
  • Splash tray to facilitate cleaning
  • Cleaning mode – The mill by default moves to the maximum gap
  • Reverse roller direction
  • Emergency stop function
  • Acrylic cover provided for the roller , operated with proximity switch
  • Quiet operation due to non-metallic gears and timing belt drive
  • Manual roll turning for safety while cleaning
  • Sealed water cooling
  • Safety clutch allows rolls to be turned for cleaning with motor off
  • Safety cover shields turning rolls
