Learn MoreCoal 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

Learn Moreto grind as coal properties move away from normal. For instance coals with a moisture content of less than about 10% behave in an expected manner. However as moisture content increases the HGI becomes les effective as a predictor. Essentially there is an envelope of coal properties within which HGI is reliable. This envelope is not well defined.
