US 12,544,795 B2 · Recycling waste refractory material

Abstract

A refractory recycling system includes a network of refractory aggregates including a first contaminant and an individual refractory component desired to be separated from the first contaminant, a computing device configured to determine a first critical velocity for separating the first contaminant from the individual refractory component, the first critical velocity being determined based on a mechanical property of the first contaminant, and a refining apparatus for refining the network of refractory aggregates. The refining apparatus is configured to receive the network of refractory aggregates, generate the first critical velocity based at least in part on a projecting mechanism, impart the first critical velocity to the network of refractory aggregates, thereby causing the first contaminant to separate from the individual refractory component, and provide a first refined set of particles of the network of refractory aggregates, the first refined set of particles comprising the individual refractory component.
