Coal briquettes have long been produced as a means of using up 'small coal', the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is hard to arrange adequate airflow through a fire of these small pieces; also such fuel tends to be drawn up and out of the chimney by the draught, giving visible black smoke.
The first briquettes were known as culm bombs and were hand-moulded with a little wet clay as a binder. These could be difficult to burn efficiently, as the unburned clay produced a large ash content, blocking airflow through a grate.
Our products are principally used as raw material and processing agent in Blast Furnaces of steel plants and cement industries. We also supply to Corex plants. Some industries use our product in their cupola foundries, electric arc furnaces, etc. Some plants procure Dry Coke using in SMP for smooth and uniform charging in Lancing Tubes.
