Types of dry rawmill include ball mills, roller mills and hammer mills. Ball mills These are similar to cement mills, but often with a larger gas flow. The gas temperature is controlled by cold-air bleeds to ensure a dry product without overheating the mill.
Generally, two types of paper and pulp mills are seen in the world, i.e. (i) Raw material-based, and (ii) Market-based. In some countries, mills produce only paper while in other countries they produce wood pulp as well as paper. The pulp is mostly used by paper industries. Therefore, for obvious reasons, pulp and paper industries are always ...
