Abstract: A star feeder for conveying all types of bulk materials having a comminuting insert for crushing bulk material agglomerates (29). Bulk material agglomerates are conveyed into the inlet of the star feeder (1) and there pass through the comminuting insert (10), which comprises at least one shearing wall (20), which includes at least two mutually angled shearing surfaces (21, 22), which widen upward, toward the inlet direction (11) and meet centrally in the region of at least one feed edge (23).

Abstract: A star feeder for conveying all types of bulk materials and having a comminuting insert for crushing bulk material agglomerates (29) which are conveyed into the inlet of the star feeder (1) and there pass the comminuting insert (10), on which there are disposed devices for comminuting the bulk material agglomerates (29), wherein the comminuting devices are formed of at least one shearing wall (20), which shearing walls form at least two mutually angled shearing surfaces (21, 22), which widen conically to the inlet direction (11) of the bulk material upward in the inlet direction (11) and meet roughly centrally in the region of at least one feed edge (23), the longitudinal extent of the feed edge (23) widening conically in the inlet direction (11).
