Abstract：According to gravity-fed three-product dense medium cyclone and coal slime dense medium cyclone had been widely used, the limit of gravity separation reached 0.1 5 mm, the incompatibility of curved screen with 0.4 mm sieve mesh for coarse clean coal slime was analyzed in this paper.It was introduced the prediction of ash, grain size distribution of feeding, coarse particle screening efficiency using curved screen with 0.1 5 mm sieve mesh, which provided technical basis for the replacing feasibility of 0.4 mm sieve mesh.
Keywords：lean coal slime curved screenfine sieve screenoarse particle screening efficiencypneumatic beater
