  • Suspension application apparatus and method for manufacturing rare earth magnet
    Patent number: 6548014
    Abstract: A suspension application apparatus for applying a suspension containing powder particles of an oxide dispersed in a liquid to a plate for magnet sintering, the oxide having a specific gravity greater than the liquid. The apparatus includes: a container for storing the suspension; a stirrer for stirring the suspension stored in the container; a transport path through which the suspension is transported from the container to the plate; and a homogenizer for homogenizing the suspension by applying a mechanical force to at least part of the suspension flowing through the transport path.
    Type: Grant
