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 ...

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...

At present, there is a tendency to be replaced by vertical mills, roller presses, etc., but the ball mill has a "granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration hardening". The special advantage is that this is the main reason why clinker mills still use ball mills. 2.

Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
