Coal Swelling Index and Roga Index Testing Apparatus for Efficient Coal Evaluation

The apparatus is designed for coal testing and is used to evaluate the sintering ability of coals. The methods consist of rapid heating at constant pressure of a mixture of coal with a sintering additive and determining the mechanical strength of the coal. additive and determination of the mechanical strength of the non-volatile residue in a laboratory drum. The apparatus consists of two main parts: <ul> <li>- a press for compacting the mixture of coal and stripping agent in the crucible;</li> <li>a double drum with an electronic time relay, which allows two tests to be carried out at the same time.</li> </ul>simultaneously.
