Coal pulverizers are used to dry, grind and classify. Drying is achieved as hot gas passes through the pulverizer and removes moisture from the pulverized coal. The hot gases used should have a low oxygen content, this reduces the likelihood of accidental combustion within the mill. It is possible for hot gases to be taken directly from the ...
