Further Testing of an Eddy Current Separator for the Recovery of Aluminum from Municipal Waste. Test No. 5.02, Recovery 1, New Orleans

摘要

The report documents three series of test runs (collectively, Test No. 5.02) of the eddy current separator that recovers mainly aluminum cans from a processed portion of municipal refuse at the New Orleans resource recover project (Recovery 1). This was accomplished by holding the feed rate constant and varying the belt speed to convey the fixed amount of material through the magnetic field faster or slower. For comparison, there is also one test run at each belt speed with only aluminum feed cans as the feedstock. The output streams of the eddy current separator from each test were analyzed for aluminum can content in three can-shape categories; the product stream was also analyzed for contamination. The efficiency of the eddy current separator in recovering each can-shape category as well as product purity were determined for each test run.
