Roller Grinder

A roller-grinder is a specific type of mill used to grind a wide range of products, while an HD roller-grinder is a specific type of mill used to grind a high capacity of a wide range of products.

Roller-grinders have the ability to break down products to a consistent particle size without over-processing the material or creating too many unwanted ‘fines’ that diminish the quality of the finished product. The key difference between a roller-grinder and a roller-mill is that a roller-grinder has the ability to run each roll in a set at a different speed. This differential between the speed of the rolls creates a grinding action that is desirable for many applications.

Roller-Grinder Features:

  • Heavy-duty construction.
  • Solid chilled iron rolls with heavy-duty 2-15/16” shafts.
  • Spring protection designed to prevent damage to the rolls in the event that overly hard foreign matter makes its way into the mill.
  • Variable speed feed roll.
  • Hydraulic roll opener (choice of manual pump or electric hydraulic pump).
  • Tapered roller bearings for improved bearing life.
  • Removable plate magnets.
  • Sample port.

[1] Some motor ratings have several values because motors lower on the mill have no need to be as powerful as the motor that runs the first set of rolls. Experience has shown that as the material passes through consecutive rolls it requires less power to grind down to a smaller particle size. IFA takes pride in being straightforward with this information and building mills that meet the needs of the customer without charging extra for motors that are more powerful than they will ever need to be.[2] Weight estimated for shipping and handling.
