“…In this work, the effective density for immersed object separation in the GSFBCB is studied both theoretically and experimentally for coal beneficiation − and potential applications, e.g., iron/copper ore upgrading, − municipal solid waste treatment, , and agricultural crop cleaning. , An attempt is made to correlate the effective density with the feed properties and operating parameters, which could be used to evaluate the influences of process variables on the separation effectiveness of the GSFBCB. To offer a reliable prediction, almost all available experimental data in the literature are used in developing this correlation.…”

Effective density for the separation of immersed objects which determines the performance of coal dry beneficiation is of primary importance for Gas−Solid Fluidized Bed Coal Beneficiator (GSFBCB) applications. Of all factors affecting the effective density, fluidization hydrodynamics and properties of medium particles and immersed objects play the dominant roles. By correlating all available experimental data found in the literature, a general correlation has been developed for the first time to predict the effective density for immersed object separation in fluidized beds, ρ sep = 0.95ρ bed + 1.88ρ drag , where ρ bed is the fluidized bed density, and ρ drag is the effective bed density contributed by fluidization hydrodynamics. This correlation could accurately predict the effective density for various immersed objects in fluidized beds with single or binary particle systems in existing experimental results. With wide applicability and great accuracy, the proposed correlation not only provides an efficient way for the design and operation of the GSFBCB for coal dry beneficiation but also is applicable for iron and copper ore pretreatment, agricultural crop cleaning, municipal solid waste classification, etc.
