Deterring wear at a bearing construct in a basket media mill

摘要

A media basket mill utilizes a media bed having very small media to attain a mixture of finely divided solids in a liquid vehicle. A bearing construct which journals the rotor of the basket mill within the basket of the mill includes a bearing which is protected against excessive wear by including a recess in the rotor. The recess is juxtaposed with the bearing and communicates with the media bed such that upon rotation of the rotor to pass feedstock through the media bed for a mixing operation, media and feedstock in the vicinity of the bearing will be directed from the recess into the bed of media and feedstock outside the rotor, thereby diverting media and feedstock away from the bearing and deterring excessive wear which might otherwise result from media and feedstock interacting with the bearing during rotation of the rotor for the mixing operation.
