Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...

Vertical roller mills are a newer type of coal grinding mill and are characterized by their higher grinding efficiency, reduced maintenance requirements, and higher drying capacity. They use a rotating table to crush and grind the coal material, and a series of rollers to compress and squeeze the coal particles, producing a fine coal powder.

Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.

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.
