Abstract

A system for recycling pocketed metal coil mattresses includes a primary shredding station that implements a primary shredder element having a housing with opposing shafts mounted to extend along sidewalls of the housing. Each shaft includes a plurality of opposing shredding knives configured to bypass each other for shredding materials in the housing into metal and fabric pieces. The knives each have a thickness in the range of 17-50 mm with the knives of each respective opposing shaft being spaced apart from each other along the respective shaft in the range of 17-50 mm. The primary shredder element is free of stationary elements in the spaces between the shredding knives at the sidewalls. A motion separation station utilizing motion of the fabric pieces and the metal pieces for separating the pieces follows the primary shredder station. An air separation station provides an airflow to separate fabric pieces from the metal pieces. A secondary shredding station for further shredding the material is used to further shred and separate materials. A magnetic separation station further separates the metal and fabric pieces.
