coal parameters affecting pulverizer output. while selecting a pulverizer, the coal characteristics play an important role. the hardgrove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. the hardgrove index of coal tells us about the ease with which it can be pulverized.
thermal power plants use different types of coal pulverizers. the method used is attrition, impact, or a combination of both. this article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
