PET & rPET preform regrind systems
The new CMG series of grinding systems designed for PET & rPET preforms features integral infeed conveyor with rigid belt, stainless steel holding hopper and sides, metal detector, and enclosed feed chute to granulator. The infeed conveyor is integral part of the system, not anymore an appendix or an auxiliary device, and is controlled by the granulator so to synchronize all operations in full.
Qualitative PET & rPET preform regrind
All CMG grinders for application with PET & rPET preforms are manufactured with the highest degree of materials and components. The very unique CMG cutting chamber is the signature feature of the new line. Totally assembled form CNC machined steel parts, fabricated with tolerances down to the hundredth of a millimiter, the very high degree of precision of assembly guarantees very accurate cut, dimensional homogeneity of the regrind particles and no generation of dust.
Careful PET & rPET regrind handling
The PET & rPET preform regrind is evacuated from the granulator collection bin, positioned underneath the cuttings chamber, by a full-vacuum regrind conveying system, another very unique and valuable characteristic of the new CMG PET & rPET Preform series. Vacuum conveying through large diameter steel piping ensures no mechanical stress of the regrind with consequent absence of generation of dust. Conventional thru-fan solutions are very detrimental to the quality of the PET & rPET preform regrind. An additional benefit to the implementation of full-vacuum evacuation and conveying systems, a design of CMG, is the total elimination of pollution of powdery air to the surrounding environment.
