Metal Recovery from Dross through Rotary Crushing and Separation Producing Products Instead of Waste

Abstract

There are many areas in the aluminum cast house and smelter operations that can benefit from efficient recycling and recovery of materials thru low cost, simple rotary processing operations. DIDION has the most widely developed uses and applications for rotary crushing and separation systems for the recycling and recovery of dissimilar materials that are often mechanically bonded together. The development of this technology was started in the foundry industry in the early 1970’s. The first step was the separating of metal castings from the foundry sand mold pieces in which they were created. These hot, heavy castings required the development of a very durable machine. The equipment was next used for sand reclamation to keep these foundry materials in use and out of landfills.
