Raymond Roller Mill air-swept vertical ring-roll
A roller mill is most effective 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.

Hammer Mills vs. Roller Mills: What's Better for Your Business
ROLLER MILLS: PROS AND CONS. Unlike hammer mills, roller mills use compression to break up the feed. As the source material enters the chamber, it's struck by two roller pads that break up the feed into finer particles. Roller mills come with narrower particle distribution rates, helping you control the size and shape of your feed.
Ball Mill Refiners Vs Roller Refiners
I am researching the differences between making or shall I say refining chcolate and ingredient mixes on a ball mill refiner versus roller refiner process. There seems to be a difference of opinion.
