5. Conclusions. Determining the properties of coal, in particular, the grindability, is of great importance because coal graining plays a huge role in each use of coal: combustion, gasification, enrichment and pyrolysis. The energy consumption for breaking up (grinding) coal is significant and amounts to 515 kWh/t.
grinding capacity. The more roll pairs the mill has, the greater the size reduction it can achieve. The rolls typically have a castiron core with a 5⁄ 8 to 3⁄ 4inchthick outer layer made of alloy steel. The outer layer's surface is typically corrugated with grooves or other patterns, depending on the application. For some
The gas flow and drying capacity was normally decreased with mill size (grinding capacity). In other mills like vertical roller mills both grinding and drying take place together inside the mill by the hot gases supplied through the mill. The vertical roller mills are usually designed to have a rather constant ratio between airflow and grinding ...
