Abstract

In a method for classifying granular material for providing a fraction within predetermined lower and upper particle size limits (12 and 22 mm, respectively), use is made of a screening apparatus which classifies the material in two steps. The screening apparatus comprises a first screen (4) with an upper screen deck (5) and a lower screen deck (6). The two decks (5, 6) have openings of a size which is equal to or slightly above the respective particle size limits. From the first screen (4), an intermediate product is fed to a second screen (7) including a screen deck (8) having openings of a size which is above, e.g. 25% above the lower particle size limit. By removing oversize particles (> 22 mm) in the first screening step and removing undersize particles (< 12 mm) in both the first and the second screening step, a very clean final fraction is obtained with small proportions of undersize and oversize particles.
