The samples were ground for 0.5, 1 and 2.0 min in a mill with 0.55 m diameter and 0.2 m length (see Table 3 ), to measure grinding rates and also estimate the breakage function. The mill speed was 75% of the critical speed and mill filling was at 40% (41.205 kg of steel balls).
The weight is a direct physical measurement of the level to which the ball mill is filled with coal and it is not influenced by the moisture content or the range of particle sizes of the load consisting of the mixture of coal and balls. The monitoring method of the invention is therefore very reliable.
The Hardgrove index is determined using the ASTM method D 409–71. It involves grinding 50g of the material, e.g. coal, of specified size (16–30 mesh cut) in a specified ball-and-race mill for 60 revolutions. The amount of 200 mesh material is measured (w grams) and the index is defined as I = 13 + 6.93w. Thus, the higher the index, the ...
