For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world's largest fleet of installed power milling equipment.
In the UK, the majority of coal mills on existing power plants are fitted with static classifiers and improvements to these offer a limited means of improving the fineness of the ground product from the coal mills. A better solution is to exchange the static classifier for a dynamic (or "rotary") type.

This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.

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.
2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill.
