A method for classifying and dewatering mineral raw materials includes feeding bulk material on a screening surface of screen in the form of a metal or nylon grid and a sieve supporting thereof made of elastic tapes-strings attached on the supports, sifting and movement of material by longitudinal and transverse vibrations. The tapes-strings are mounted on the screen, they have different natural frequencies, and a frequency regulator having control ranges corresponding to the natural frequencies of the set of tapes-strings, through which the scanning modes of excitation of the tapes-strings within natural oscillations thereof. |
