ARRANGEMENT IN CONNECTION WITH A WEAR RESISTANT COATING IN PARTICLE FEEDER AND METHOD FOR PRODUCING THE SAME

摘要

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.
