Simple trommel may be arranged in series with oversize of the first passing to the second trommel and the oversize of the second passing to the third, Etc. They are quite efficient for coarse sizes. The inclination of trommel varies derived from the essence of material to be processed. The present trommel is built with screens of different sizes throughout their length, The feed entering upon reaching the conclusion of the highest quality screen. In this way it is possible to collect materials of different available in sizes originating from one trommel. Drive to the central shaft is given through a motor coupled to reduction gearbox. Set, Up is complete in all respect with guards, Bins and control panel. A special arrangement to modify the angle of inclination of the trommel is made.
