  • the sorting device taught by this additon certificate comprises a rotary drum which is formed of longitudinal bars, alternately fixed and radially movable, the relative distance of which can be modified so as to be increased in the upper part of the bar stroke for allow any products trapped between the bars to be released from them.
  • the ends of the movable bars are kept in contact with an internal toothed sawtooth ring secured to the annular flange of the drum and which can rotate slightly relative to this flange to adjust the position of the mobile bars relative to the fixed bars at will and therefore to bring the screening interval to a desired size.
  • the use of the sawtooth inner ring does not allow precise adjustment of the screening interval.
  • the movable bars pass through apertures of attached segments applied against the internal face of the flanges and of corresponding apertures pierced in the flanges so that the movable bars can slide there. It is extremely difficult to make these lights so that all the movable bars are located identical constant distances relative to the fixed bars. In other words, the screening intervals cannot be set to strictly identical values.
  • the screening interval once set, does not remain immutable because wear occurs over time, in particular due to the friction of the movable bars on the saw teeth of the aforementioned ring leading to a modification of each interval of screening.
