Abstract
Careful consideration is given to the type of cleaning equipment and control systems to be used when selecting circuits for washing fine coal (0.5 mm × 0, or 28 mesh × 0, size fraction). However, desliming, declaying, and sizing procedures required for efficient operation normally are not evaluated in sufficient detail, resulting in disappointing system performance. This paper details desliming and dewatering circuit design that is effective based on recent test data. The circuit maintains control of the 0.5 mm × 0 (28 mesh × 0) (declayed) size fraction with minimal misplaced material and maximized circuit efficiency. A discussion of circuit design parameters and control systems, as well as results from the testing program, are included in this text.
