The industry standard for over a century

The Raymond® Roller Mill is an air-swept vertical ring-roll mill with an integral classification system that simultaneously dries, pulverizes and classifies a number of different types of products including limestone, clay, minerals and others. From a feed ranging in size from approximately ½ -2 in / 10-50 mm, the roller mill can produce particles ranging from coarse, granular products of approximately 10% R2000 micron 90% minus 10 mesh (10%R2000 microns) to as fine as 99.9% minus 325 mesh (0.001%R44 micron).

Standard Sizing

Raymond® Roller Mills are available with grinding ring diameters ranging from 30-120 in / 760-3050 mm. These sizes are capable of producing a wide range of product fineness from a wide variety of material.

Applications

A roller mill is most effective in processing materials that are 5 or less on the Mohs scale of hardness. There are a few limitations, but the most practical are soft to medium hard materials. They can also be used to prepare feed for systems producing ultra-fine materials, such as a Raymond® Vertical mill, ball mill or Jet-Stream™ Classifier system. The mill provides efficient control of product size with minimal power, resulting in a flexible, cost-effective production.

Typical material processed

Clay, Fire Clay, Bentonite, Kaolin, Barytes, Gypsum, Limestone, Phosphate Rock, Talc, Coal, Hydrated Lime, Petroleum Coke, Pigments, Phenolic Resins or similar materials.
