The investigation of the influence of additional water injection in a classifier on the particle separation process characteristics has been performed on the basis of numerical modelling. It has been shown that the increase in water injection velocity leads to the increase of both the cut size and the minimal value of separation curve. The change of the injector opening size influences only the minimum value of the separation function not altering the cut size at the specified water injection velocity.
