Abstract: The intelligent coarse slime separator (TCS) is a kind of new-type teetered-bed separator (TBS). The TCS developed on the basis of the traditional TBS with the addition of a novel tailings discharge mechanism and a smart hinderance mechanism to strengthen hindered settling of particles for reducing misplacement of particle sizes and obtaining a higher separation accuracy. In view of the fact that the stacked high-frequency vibrating fine screen works with a low efficiency in recovery of coarse slime at Baodian Plant, work is made on technical transformation of the existing coarse slime recovery system with the use of the TCS based on the result of comparative analysis of the performances of different kinds of coarse slime separation equipment. The optimum working conditions of the TCS are determined through single-factor test: volume of upward current—98 m³/h; frequency of hindrance mechanism—16 Hz; and separating density—1.165 g/cm³. The use of the separator to treat a slime feed with an ash of 19.98% under the optimum conditions can produce a clean product with a yield of 35.43% and an ash of 9.39% which can be directly blended with the clean product of heavy medium separations system.
