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.
Apr 24, 2018 · Optimization can save you a lot of coal, so if you notice your city is glowing with warmth, turn a few heating elements off to preserve your precious stocks for when you really need it. You can also set steam hubs to run only during working hours, which is a great way to save energy when they are placed by places of employment.

2.3 Pulverizer Designs and Pulverized Coal Handling. Coal preparation predated pulverized coal firing, particularly for stoker units where sizing has always been very important, particularly in the minimizing of fines. Predating the development of pulverized coal firing came the development of pulverizers used in the processing of minerals.
The design "capacity" of the same pulverizer will grind 135,000 pounds per hour with fuel that is 55 HGI (Hardgrove Grindability Index) coal, ¾" raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard.
