TILE SURFACING FOR A CENTRIFUGE CONVEYOR

摘要

A hard surfaced screw conveyor for centrifuges comprising a helical metal blade mounted for rotation about the longitudinal axis of the helix and radially extending to an end surface, at least one wear-resistant member on the blade and having a portion radially extending beyond the end surface. The wear-resistant member is secured to the blade by male and female formations on the wearresistant member and the blade, respectively. The female formation has a longitudinal axis that is substantially perpendicular to the blade. The formations cooperate to preclude the wear-resistant member from moving in a direction that is radial to the conveyor rotational axis or parallel to the blade during rotation of the conveyor.
