Review on Zigzag Air Classifier

The zigzag (ZZ) classifier is a sorting and classification device with wide range of applications (e.g. recycling, food industry). Due to the possible variation geometry process settings, apparatus used for various windows operation due specifications separation cut sizes from 100 µm several decimetres, compact fluffy materials as well foils). Since ZZ gains more interest in recycling applications, it discussed this paper, regards its design, mode operation, influencing parameters research date. Research on ZZ-classifier has been ongoing than 50 years can be divided into mainly experimental studies modelling approaches.
