With steady decline in quality of the coal available for coking, particular care must be taken in batch preparation. Correct choice of the degree of coal crushing in accordance with the actual proportions of bituminous and coke-grade coal maintains the petrographic composition of the batch and...
The additivity of various measures of clinkering is verified for coal blends that contain imported coal.
The influence of grinding equipment on the contamination of the initial material is investigated. In particular, coke of different structure is ground using a drum-type ball mill, a roller mill, and a jet mill. Conclusions are stated regarding the strength of coke as a function of the...
