54-55 Package sorting In automated plants in this stage of the process the main stream is divided into three fractions: fine, rolling and light flat. The equipment needed to segregate the requested materials contained in each of these fractions is available. Rolling fraction • Film suction equipment. • Magnetic separator. • Optical separators. • Eddy current separator. Light flat fraction • Film suction equipment. • Manual sorting belt. Provided in the stations and bins needed for manual sorting of requested material present in this stream. Fine fraction • Magnetic separator. In manual plants this stage is performed by operators in charge of manual sorting of plastic materials. Metals are selected at the end of the line using a magnetic separator (steel) and an eddy current separator (aluminium). Package sorting in 2 t/h plants. Only the requested metal material (steel and aluminium) is selected automatically. The remaining requested materials are selected manually in the two remaining streams of the trommel, in the secondary sorting cabin. To reach 80% effectiveness (efficient value in manual plants) 12 sorting operators are required to sort an average of 79 kg/h*operator, assuming that the input material contains 75% requested material.
