Coal grinding mills. In conventional systems, coal grinding is carried out using ball and rod mills. Depending on the process flow diagram and the type of coal mill, the specific power consumption is very high and ranges on the average from 50 to 250 kW·h/t. Such energy input arises due to a very low energy efficiency of the equipment used.

The grindability of coal is important for entrained-flow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, choosing coals that are easier to grind can increase the overall efficiency of the process.
Grinding is an engineering process of great impor- tance for many branches of industry. It is applied prima- rily in the processing of minerals, and in particular coal, silica, limestone, sulphur and other useful minerals, as well in metallurgy, pharmacology, materials engineer- ing, the power industry and other fi elds.
