Abstract (en)

[origin: DE19546019C1] The invention concerns a pusher centrifuge comprising a centrifugal drum (1), a pusher base (5) and a filler pipe (11) for the material to be centrifuged, the pipe projecting coaxially into the centrifugal drum and being connected to the centrifuge housing (10). The pusher centrifuge further comprises a concentric distributor cone (6) which follows the filler pipe and whose end with the larger diameter terminates at a spacing in front of the pusher base (5), leaving free an annular gap (9). The pusher centrifuge is characterized in that a concentric annular cup (7), which surrounds the end of the distributor cone (6) facing the pusher base and projects into the centrifugal drum (1), is secured at the pusher base (5).
