Abstract Pulverised coal preparation system (Coal mills) is the heart of coal fired power plants. The complex nature of a milling process, together with the complex interactions between coal quality and mill conditions, would lead to immense difficulties for obtaining an effective mathematical model of the milling process.

4. Hammer mills : The principle of operation of hammer mill is shown in Figure C. These mills have swinging hammers or bars, into the path of which is fed the coal to be pulverized. Grinding is done by a combination of impact on the large particles and attrition on the smaller ones. Hot air is given to dry the coal.

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.
