Blow Moulding 101
Many are the very innovative and unique attributes of the new series and all contribute to obtaining the highest degree of productivity, regrind quality (homogeneous particle dimensions and absence of dust), the efficiency of operation, cleanest environment, and the lowest TCO. The standard configurations of the new series cover capacities start from 20 kg/h all the way up to 1500 kg/h. The new range is composed of 11 granulator models, all purposely designed for grinding blow-molded containers or bulky objects.
11 new complete system configurations
The new CMG series of grinding systems designed for Blow Moulding applications features an integral infeed conveyor, metal detector, and enclosed feed chute to the granulator. The infeed conveyor is an integral part of the system, no anymore an appendix or an auxiliary device, and is controlled by the granulator so as to synchronize all operations in full. All granulators operate in high-efficiency conditions, are all equipped with EISA premium-efficiency motors, and can have AMP controls (Adaptive Motor Power). Regrind evacuation, dedusting, and air filtration are all automatic and require no maintenance. Energy utilization is 20 Wh/kg vs the 40 Wh/kg of conventional solutions.
Highly qualitative regrind
All CMG grinders for Blow Moulding application 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 from CNC machined steel parts, fabricated with tolerances down to the hundredth of a millimeter, the very high degree of precision of assembly guarantees very accurate cut, dimensional homogeneity of the regrind particles, and no generation of dust. Additionally, the high precision of fabrication reduces frictions and abrasions. No cooling water is necessary, irrespective of the application.
No powder generation or pollution
The regrind is evacuated from the granulator collection bin, positioned underneath the cutting chamber, by a full-vacuum regrind conveying system, another very unique and valuable characteristic of the new CMG Blow Moulding series. Vacuum conveying through large-diameter steel piping ensures no mechanical stress of the regrinds with consequent absence of generation of dust. Conventional thru-fan solutions are very detrimental to the quality of the regrind. An additional key 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.
Industry 4.0 controls
The new Blow Moulding line of CMG is equipped with integrated controls that monitor all functions from the moment the part to recycle is dumped on the infeed conveyor all the way the regrind is conveyed into a surge bin for subsequent utilization or into a big bag for transportation to other locations. The new controls also extend to the surge bin level management or to the automatic selection of multiple positions big bag filling station. All CMG Blow Moulding systems are certified for compliance with Industry 4.0.
