A rotating gate feeder (1) for feeding substantially particulate material comprises a housing (2) and a rotor (3) and also an end cap (8) at each end of the housing. The invention is characterised in that a wear-resistant coating (6) is cast directly onto the inner wall (14) of the housing which faces towards the rotor (3). The inner wall (14) of the housing functions as an outer mould and a purpose- adapted core (15) is used as an inner mould. The housing (2) may be provided at certain points with release zones on the surfaces (14) which face towards the cast wear- resistant coating (6). One or more wear members (12) having greater wear resistance than the moulding compound may be embedded therein.
Vanne de distribution à auges rotatives (1) pour matériaux principalement particulaires comportant un carter, un rotor, et des flasques de fermeture (8) disposés à chacune des extrémités du carter. L'invention est caractérisée par le coulage direct d'un revêtement (6) anti-usure sur la paroi interne du carter faisant face au rotor (3). La paroi intérieure (14) du carter constitue le moule extérieur tandis qu'un noyau (15) conçu à dessein constitue le moule intérieur. Le carter (2) peut comporter en certains de ses points des dépressions faisant face au revêtement anti-usure (6) dans lesquelles peuvent s'encastrer des éléments d'usure présentant une résistance à l'abrasion dépassant celle du matériau moulé.
