Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.
Roller mills are the most common mill used in the U.S. Corn Belt. They are more energy efficient and generally result in a more uniform particle size than hammer mills. However, hammer mills are still in use, and preferred when the feed will be pelleted or a need for greater flexibility in particle size.
Bars are produced in fully automated Re-Rolling Mills. The Captive Power Plant of 12MW (synchronized with PDB grid) and the National Grid are the sources of electricity of the factory. Fig: Production Flow Chart . Once the bars are cooled, they are cut into desired length by means of cold shearing.
