Machines for core cleaning and calibration :

A Duvex is a cylindrical sieve in which a drum turns at high speed. The drum is equipped with paddles, mounted in helicoïdal way. These paddles rub the material against the sieve and make small particles (dust, small fibres, small core) fall through the sieve. Depending on the sieve that is applied different sizes of core can be separated. Equipped with bars in stead of sieves the Duvex can be used as tow or fibre cleaning machine.
