Factors to Consider When Selecting the Proper Roll Crusher

This angle of nip ensures that the crusher has the ability to grab the feed material and pull it into the crushing zone without delay. If the roll diameter is insufficient in this regard, a few issues begin to occur, most notably loss of capacity and accelerated wear of the crushing elements.
