Abstract: For the current situation of partial washing of fine coal (-13 mm) and non separation of coarse coal slurry, and problems
such as high ash content and instability of coarse slime of Yadian Coal Preparation Plant, the teetered bed separation system was
added to the coarse coal slurry sorting link while expanding the capacity of the fine coal washing system of the coal processing
plant. This paper introduced and analyzed the separation principle, structure and characteristics of the teetered bed separator. The
application example in the coal preparation plant and the comparison of test data before and after the transformation of the plant
showed that teetered bed separator played a good role in improving the recovery of clean coal and stabilizing the content of coarse
and fine coal ash in the coal preparation plant. Compared with before, the clean coal recovery rate of the coal preparation plant
has increased by about 6%, increasing the economic benefits of the enterprise.
