【Abstract】 The flotation regularity of coals with different sizes and operation conditions was investigated. A big system model of multielement, nonlinear, and multi equation related to the flotation rate constant of coals different in size and density and to the operation varibles was established through the multielement nonlinear regressive analysis. On the basis of this, the continuous operation of flotation machine was simulated using the time discretization model. And a flotation simulator has been worked out, which can dynamicly display the changes of operation varibles and the influence of flotation product on operation varibles.更多还原
