Coal-water slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, Siberia. The coal-water slurry fuel was transported through a pipeline to Novosibirskaya TEC-5, Novosibirsk, a distance of 262 km (163 mi). The pipeline had three intermediate pumping stations.

Marked Ball Wear Tests. The effect of mill atmosphere on the ball wear of mild steel during grinding of coal with and without additions of pyrrhotite is shown in Figure 1. The ball wear after 60 minutes of grinding increased from 4.7 to 8.5 to 23.0 mg/ball when the mill atmosphere was changed from nitrogen to air to oxygen, respectively.

The raw material is fed into mill by feeding equipment. The hot wind enters into the mill from inlet end. As the mill cylinder rotates, the coal and hot air exchange heat in the mill. The coal is crushed and grinded in the mill. When the coal is being grinded, the powder is brought out of the mill by the hot air going through the mill.
