Schnitzer Steel Industries
The goal of this project was to improve the liberation of nonferrous metals from nonferrous raw material at Schnitzer Steel Industries. The objectives were to understand the mechanics of cohesion between molecules and determine the effects of cohesion on screening and liberation efficiency. By conducting moisture analysis and sieve tests, an understanding of agglomeration and cohesiveness was developed. The moisture was determined to be the cause of clumping and has a direct effect on screening capabilities. The results conclude specific moisture contents have negative effects on screening capability at specific size ranges. Due to time constraints, further research must be conducted to verify the effects of moisture on industrial screening processes and liberation yield efficiencies.
