The broken coal is then fed into a mill which turns it into a powder. Coal mills are of differing types. The three main types in use today are ball mills, bowl mills, and hammer mills. A ball mill consists of a rotating cylinder or tube containing steel balls. Coal is introduced into the tube and the tumbling steel balls crush it to powder...control cylinder to remove any particles that may have adhered. (8) Take hydrometer readings after elapsed time of 2 and 5, 8, 15, 30, 60 minutes and 24 hour. Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …...when a coal mill is empty), thus avoiding the generation of sparks. • Particularly suitable for easily-combustible dust with a high proportion of volatile matter (e.g. brown coal, wood, etc.). • Low-vibration mill running, even in partial load ranges down to 20% of the mill load, thanks to individually-guided grinding rollers.
