Abstract

1482396 Mineral-mining cutter drums GebR EICKHOFF MASCHINENFABRIK U EISENGIESSEREI mbH 15 Oct 1975 [29 Oct 1974] 42133/75 Heading E1F A cutter drum for mounting on a universally pivotable boom of a heading machine and having on its peripheral surface at least one helical rib 7 for conveying mined material axially of the drum and for supporting along its radially outer edge cutting tools for mining material is characterised in the or each rib increases radially in height from one end of the drum to a point intermediate the ends of the drum and then decreases radially in height towards the other end. Preferably the configuration of the drum is such that the envelope swept out by the or each cutter toolarmed rib is in the form of two truncated cones whose generated surfaces intersect substantially at right angles.
