Cylindrical sieve for screen charging machine e.g. for brick manufacture has screening bores arranged with central longitudinal axis at right angles to dispenser arm

摘要

The sieve has screening bores in its wall and a central rotating sickle-shaped dispenser arm. The central longitudinal axis (45) in each bore (40) extends at an angle to the radius line (50), which is larger than 0 deg but smaller than 90 deg . The screening bores are arranged, so that a bore axis is at an angle of approximately 90 deg relative to a line, which begins at the end of the dispenser arm and extends tangentially to it.
