摘要:
The present disclosure generally relates to systems and methods for fractionating crude biowaste (450) by at least one size separation step (30) and at least one of density separation (150), X-ray separation (160) and optical sorting (170) to form a cleaned biowaste (47) stream enriched in cellulosic material, a waste stream comprising inorganic compounds (151), and a plastics stream (175).
摘要:
A plant (1) for separating labels, caps and other contaminating materials from containers and bottles made of plastics, in particular bottles made of PET, suitable for being positioned downstream of a rotating drum apparatus (2) for removing said labels from the respective bottles comprises collecting means (3) for receiving products (P) coming from the drum apparatus (2), conduit means (4) extending along a conveying path (C) and connecting the collecting means (3) to a storing group (5) for the labels; along the conduit means (4) there are defined a first-stage separating unit (S1), that separates from the products (P) a first fraction (F1) containing the bodies and heaviest materials and leaves a second fraction (F2) free to advance that containers, bottles and/or containers and labels; a second-stage separating unit (S2) that separates from the second fraction (F2) a third fraction (F3) that comprises bottles and/or containers, and lets a fourth fraction (F4) containing mainly labels advance along conveying path (C); at an end (8) downstream of the conduit means (4) there is defined an end-stage unit (S3) for receiving and accumulating fourth fraction (F4) containing labels; fan means (9) is provided positioned upstream of said first-stage unit (S1) for generating a first air flow (X1) suitable for conveying the second fraction (F2) of products to the second-stage separating unit (S2), and sucking means (10) positioned near the third-stage separating unit (S3), for generating a second air flow (X2) suitable for removing and conveying to the storing group (5) the fourth fraction (F4) comprising labels.
摘要:
A process for classifying water-absorbing polymer particles, wherein screens having different mesh sizes are used before and after surface postcrosslinking to remove the undersize (fines).
