  • 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 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 of 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 there is wear over time, in particular due to the friction of the movable bars on the saw teeth of the aforementioned ring, causing a modification of each interval of screening.
  • the prior sorting device requires the use of a very large number of parts comprising grooved pulleys carried by the ends of the movable bars and of springs constantly maintaining the movable bars in a position remote from the center of the drum and close to the bars. fixed surrounding them, these springs also allowing the movable bars to move away from the fixed bars to release products trapped between the bars.
