Inspection and selection of granules
SortYx is the system for inspecting and selecting granules based on various parameters: shape, size, colour and chemical composition. Especially useful for lines using reprocessed materials (PCR), it allows granules to be separated, improving the quality of the batch before being processed on the extrusion line.
A suitable vibrating system creates a planar bed of granules that advance at a controlled speed towards a chute, which is followed by a phase of free fall. During the fall, the granules pass through the focal plane of a camera system which, thanks to various optics and specific illuminators, analyses their shape, size and color; thanks to IR technology, it is also possible to identify their chemical composition. Granules that do not meet the selection parameters are separated thanks to a ballistic system, creating two separate channels for selected and rejected granules.
