Pelletization of fine coals. Final report (Technical ...

31.12.1995  Successful utilization of these fine coals is economically important to the coal industry and to their major customers, the electric utilities. Besides creating air pollution, coal fines pose severe problems in their dewatering, thermal drying, handling, transportation and storage. Pelletization, a model of agglomerating fine particles can alleviate some of these problems. This study was undertaken to ascertain the process and economic feasibility of the pelletization
