Abstract
Disclosed are systems and methods for refractory recycling that result in refined individual refractory components from a network of aggregate refractory components based on a fragmentation process. In one embodiment, a network of refractory aggregates is crushed and deposited into a refiner machine. The refiner machine includes a blast chamber that houses a projecting mechanism. The deposited aggregate material is propelled from the projecting mechanism at a critical velocity. Upon impact with an inner lining of material within the blast chamber, contaminant particles can fracture apart from the deposited aggregate material, leaving a refined individual refractory component.
Claims20
A method for refractory recycling, comprising:
- cleaning a network of refractory aggregates to remove residual foreign particles;
- determining a maximum aggregate size of an individual refractory component of the network of refractory aggregates to be extracted, the maximum aggregate size being based on a mechanical property of the individual refractory component among the network of refractory aggregates;
- crushing the network of refractory aggregates so that individual particles of the crushed network of refractory aggregates are sized greater than the maximum aggregate size;
- filtering the crushed network of refractory aggregates by size to produce retained particles that are equal to or greater than the maximum aggregate size;
- and
- depositing the retained particles into a refiner machine, the refiner machine comprising a blast chamber and a contaminant collection system,
- wherein the blast chamber comprises a projecting mechanism and an enclosed outer wall, the projecting mechanism configured to spin at a set rotational speed that causes the retained particles to be propelled at a directed velocity at a stationary lining of material surrounding the enclosed outer wall, the directed velocity being determined based on a mechanical property of contaminants of the retained particles, the propulsion of the retained particles at the stationary lining of material producing refined particles comprising the individual refractory component, the refined particles being separated from the contaminants.
