The Sturtevant Whirlwind® Air Classifer is specifcally designed to separate animal byproduct feeds including poultry meal, porcine MBM, beef MBM, lamb MBM, and fish
meal into two fractions. The first fraction, typically the finer discharge, is the premium product containing lower ash with higher protein and mineral content than the coarse discharge. The coarse product with regular ash and regular protein may be sold as poultry meal feed or organic fertilizer, or can be blended with other feed ingredients allowing for a wide variety of custom formulations suitable for particular customer needs.
