Abstract
When coal is crushed, it fractures along the bedding planes and also along the boundaries with mineral inclusions. In the latter case, the mineral inclusions are released and separated from the coal. The release of the mineral inclusions may be precisely measured, but special instruments are required and these methods are of little utility. In the present work, the release of mineral inclusions is calculated by means of the Hancock–Luyken formula for coal from three Russian fields. Different crushing methods are employed. The dispersion coefficient N indicates similar results for hammer crushing of coal from different fields. The effect on the mineral inclusions is basically the same when different disintegration methods are used. However, little crushing is observed when using the KID-300 hybrid system and two-stage treatment in the DShch-60×100 jawbreaker and the DG-200×125 roller system.
