Abstract
Bulk material cleaner (1) comprising a support frame (2) and a screen housing (3), which can be oscillated and/or vibrated by a drive (5). At least one screen (6) is arranged in the screen housing (3). The screen housing has a feed opening (7) and at least two outlet openings (8, 9), the outlet openings (8, 9) being for a first fraction (F1) and a second fraction (F2), respectively. Moreover, the bulk material cleaner (1) comprises an air separator (10), which is only fastened on the screen housing (3).
Claims8
A bulk material cleaning device comprising:
- a support frame, and
- a screen housing which is mounted on the support frame by spring elements in such a way that the screen housing can be set in oscillation and/or vibration by a drive,
- wherein at least one screen is arranged in the screen housing for separating bulk material into a first fraction and a second fraction,
- the screen housing having an inlet opening and at least two outlet openings, respectively, for the first fraction and the second fraction, and
- the bulk material cleaning device further comprises an air separator which is only attached to the screen housing so that the air separator can also be set into oscillation and/or vibration by the drive,
- wherein the air separator is a centrifugal separator which comprises a jacket having a rotationally symmetrical inner jacket surface and an inner element that is arranged coaxially thereto and has air passage openings, and the inner element extends over an entire length of the centrifugal separator.
