The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table, and at the fan exit for exhauster systems. These are the prime locations of fires.
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.
