A method and a system for separating elements of waste materials of non-fibrous material from elements of waste materials of fibrous material in a waste materials separation system

摘要

A system (1) for separating elements of waste materials of non-fibrous material from elements of waste materials of fibrous material in a waste materials separation system which separates material elements of recyclable material, comprises a materials intake building (6) which receives unsorted recyclable material elements and conveys the unsorted recyclable material elements to a materials processing building (7) where the unsorted recyclable material elements undergo a number of material pre-sorting steps and material separation steps. With the recyclable material elements sorted by material and grade of material, a first optical separator (37) is configured to displace non-fibrous material elements from fibrous material elements in a stream of elements passing through the first optical separator (37) in response to the distance detected between a non-fibrous material element and the nearest fibrous material element exceeding a predefined distance. The fibrous material elements and the remaining non-fibrous material elements in the stream of elements which pass through the first optical separator (37) are conveyed to a second optical separator (48) in which non-fibrous material elements are displaced from the stream of elements. The remaining elements which pass through the second optical separator (48) are baled into bales of fibrous material elements with fibrous material elements of a substantially similar grade of material.
