Structural optimization of a multistage inertia pulverized coal concentrator

A multistage inertia pulverized coal concentrator was tested and simulated based on orthogonal experiment theory and numerical simulation method, during which the influence of structural parameters of the coal concentrator on the rich/lean ratio of pulverized coal was studied, and hence an optimized structure was obtained by orthogonal design. Results show that compared with the concentrator designed based on empirical data, the optimized concentrator has a higher separation efficiency, which therefore may serve as a reference for research and development of inertial pulverized coal concentrators.
