The apparatus is designed for testing coal according to GOST 20330 (ISO 501-81) "Coal. Method
Determination of the index of swelling in the crucible".
The apparatus allows to determine the swellability of coal during rapid heating in a closed crucible.
As a result, the obtained coke residue (korolek) is compared with the scale of standardised
profiles for assigning a number - the bulking index.
The control unit integrated in the machine allows to automatically maintain
temperature regime according to the standard.
