The washery has adopted a water-sludge system using centrifugal conical grates in the operation of sludge removal from the run-of-mine coal before jigging, dewatering of the large and fine coal machine concentrate and control classification of the primary and secondary sludges. The system was designed to separate and dewater the coarse sludge, then adding it to the flotation concentrate. The addition of the coarse sludge resulted in a decrease in the quantity of the dryer drum feed (from 27 to 23%), which decreased the moisture content of the dried product by 4 to 5%. The improvement in the granular composition and the decrease in the moisture and quantity of coal being dried stabilized the charging of the dryer drums, thus increasing the capacity and efficiency of the drying process. 1 table.
