The intermediate crushing in the cut roll crusher is mainly used for the crushing of brittle materials like concrete and clay sintered bricks, along with the compression of rough materials like wood and fabric (to avoid being too small in size) after the coarse (primary) crushing. The selective crushing in this process is good for the separation of impurities.

The surface roughness of sugar mill rolls is recognised as being a critical factor in the feeding and juice extraction processes that occur in a milling train. During the past five years, there has been renewed interest in the application of long-life rough surfaces to minimise maintenance costs and minimise the need for roll arcing. These new surfaces usually have smaller, more numerous and ...
