Fine Grinding of Brittle Materials
|
|
|
|
High Compression Roller Mills are used for the fine grinding of brittle materials and not for crushing (like roller
crushers) or for the compacting of materials (like roller compactors). The feed size is usually a little bit bigger than the gap width between the rollers. But it also can be smaller than the gap as it
is in roller compactors.The material bed is highly compacted so that for nearly all materials flakes are generated instead of a granular product as it is done by roller crushers.
