Scalping :- In the scalping process, the screener consists of a single screen and "takes a little off the top" — it removes a small number of large particles from the surface of a material that's almost entirely within a particle size spec (or on-size).Typically, the material that enters the screener contains 95 percent or more on-size particles.
