PROCESO Y APARATO PARA RECUPERAR UN TERMOPLASTICO DE MATERIAL TEXTIL REVESTIDO DE DESECHO

摘要

The invention relates to cryogenically cooling and impacting thermoplastic coated fabric to liberate the thermoplastic from the fabric and screening the resulting thermoplastic fabric mixture in a multi-deck vibratory screener into a coarse fabric segment, a thermoplastic fines segment and a third segment. The third segment is separated into a fabric fines segment and a coarse thermoplastic segment in, for example, an air classifier. The recovered thermoplastic coarse and fines segments can be reused in all applications for regrind thermoplastic material.
