Crushing McLanahan

The particle size is controlled by how fast and how far the material is thrown. With both types of impact crushing, material that has reached the desired size falls through the chamber, while the larger pieces remain subject to further impact. Both hard rock and soft material can be reduced using impact crushing.

Jaw Crushing Jet Milling, Ball Milling AVEKA

Crushing is a mechanical size reduction process for large chunks of friable material such as rocks or ceramics. The crushing is achieved by using compressive forces between two plates to break the substrates. One plate is typically fixed in a “V” alignment while the other plate reciprocates resulting in the crushing action.
