Innovation & Performance: New cutting chamber design
CMG is introducing a brand new cutting chamber design for its Evoluzione series granulators. The new rotor configuration allows the rotor blades to cut the plastic feedstock perpendicularly against the bed blades, obtaining the highest degree of cutting penetration and precision.
The rotor blades are mounted on the edge of the rotor holding modules and not on a holding block. Not only this feature is beneficial, as the inclination of the rotor blades is very high, but it also allows easy and quick servicing/replacement of the blades, with comfortable access from the front of the machine.
The rotation of the rotor does not produce the very detrimental “drag” effect, meaning the mass of material being ground in the cutting chamber does not rotate with the rotor producing lots of dust and fine particles, that will all become waste through the washing line. The production of fine particles is reduced to few percentage points, versus a common 15% or more from conventional granulators.
The rotor is of the open type design, taking only 30% of the cutting chamber volume.
The rotor/cutting chamber volume utilization ratio is 30/70, versus alternative ordinary granulators with 70/30 ratio. This feature alone allows more than double the quantity of material in the cutting chamber. The more is the material in the cutting chamber, the higher is the capacity of granulation.
The new cutting chamber has the so called “tangential set up”. Such characteristic confers voraciousness and guaranteed bite, with no need of feeding aid devices, commonly utilized with conventional granulators.
Evoluzione series super granulators for post-consumer recycling
With the new Evoluzione series, CMG presents the EV916 and EV616 models, solutions suitable for the most critical operating conditions, for wet or dry granulation, which require high performance characteristics such as granulation capacity from 2,000 to over 5,000 kg/h, versatility, efficiency and sustainability. The Evoluzione series guarantees operational consistency and wear resistance of a higher degree, with its construction solutions that involve the use of harmonic steel, Hardox and assembled modular structures. In addition to the precision to the hundredth of a millimeter on the construction of the new cutting chamber, which allows a much longer duration of the blades when compared to conventional models, all the Evoluzione are equipped with advanced controls, in the Industry 4.0 style, to make the machine functions 100% monitorable and manageable. Operating temperature, blade wear, productivity, operational efficiency, energy use, all functional parameters managed on the machine or remotely, with connectivity based on the OPC-UA protocol, are just some distinctive features.
High efficiency shredders: TRM600 with patented blade design
The CMG Granulators patented shredder blade design provides the highest degree of cutting precision. The blade is inserted in a V shaped slot on the rotor. Such assembly provides the highest resistance to mechanical stress and the best cutting performance. Shredding is amongst the initial phases of the recycling process. Post consumer plastics require reduction in size prior to being washed and to go through the secondary sorting phase. Shredding precision allows dimensional homogeneity and absence of small particles. Along with a unique blade design every CMG shredder is equipped with advanced controls to self adjust motor power and rotor RPM, to obtain the highest quality of the shredded plastic with the lowest utilization of energy.
CMG Granulators is one of the very few suppliers of recycling equipment that produces both granulators and shredders. The range of CMG shredders covers small to medium capacity applications, in kg/h: from 200 to 1.500. The TRM series is represented by four models, TRM600, TRM900, TRM1200 and TRM1500, all equipped with the most advanced blade design, covered by patent, and intelligent PLC based controls.
Purpose designed GT line for thermoforming
CMG Granulators introduces a newly designed granulator series for in-line scrap recycling, suitable for sheet, skeletal sheet and reject parts grinding.
The new GT series comprises four models, suitable for small to medium capacities, to cover applications ranging from 200 through to 1.000 kg/h.
The signature feature of the GT series from CMG Granulators is the blade set up design: the rotor blades are positioned at a high degree of inclination, 50°, in respect to the bed blade, so to guarantee the best cutting precision, the highest dimensional homogeneity of the regrind, the lowest sound emissions and absence of powder.
The cutting chamber is “bolt & dowel” assembled, does not utilize cast or welded component and all parts are CNC machined to obtain the highest precision of assembly to the 100th of millimetre.
20 Wh/kg is the small amount of energy that a CMG granulator uses, compared to over 40 Wh/kg that a conventional unit consumes.
All the GT models are low profile and sound enclosed, so to be positioned right underneath the finished product conveyor belt and to keep the production environment the quietest possible.
The New G26 Line: flexibility of application and dependability
CMG presents the new G26 granulator line, for application with injection molding, blow molding and extrusion processes. 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), efficiency of operation, cleanest environment and the lowest TCO. The standard configurations of the new series cover capacities starting from 50 kg/h all the way up to 300 kg/h.
The new G26 Line is made of three models: G26-30, G26-45 and G26-60. The line features integral sound enclosure and a very innovative feed hopper design to accommodate the widest variety of shapes and dimensions for the parts to grind. All models operate in high-efficiency conditions, are all equipped with EISA premium-efficiency motors and can have AMP controls (Adaptive Motor Power). Energy utilization is 20 Wh/kg vs the + 40 Wh/kg of conventional solutions.
New Blow Moulding Solutions
CMG will put on display a new series of recycling system solutions for application with blow molding machines. 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), efficiency of operation, cleanest environment and the lowest TCO. The standard configurations of the new series cover capacities starting 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. At Plast show 2023 will be displayed G35-60 and N55-90 models.
Purpose designed screen-less granulators SL series for highly technical injection molding
CMG launches a new series of low speed screen-less granulators with innovative and unique attributes, all contributing to obtaining the highest degree of regrind quality (homogeneous particle dimensions and absence of dust), efficiency of operation, ease of cleaning and the best application flexibility. The new SL range consists of four models, for capacities going from 5 kg/h up to 30 kg/h.
The new SL granulators by CMG are designed to produce the most homogeneous regrind shape and dimensions, without any dust. The rotor cutters perform a fine and precise cut of the parts to regrind and do not fracture or crash them as conventional screen-less granulators do. The sector grinding elements are available in three different sizes, to obtain the most adequate regrind size for the injection process. The great advantage of dimensionally adequate regrind is most appreciated when the SL granulator is coupled with small tonnage injection moulding machines. The SL granulators produce regrind having dimensions comparable to the virgin pellet.
Another unique feature of the SL series is the metal trap positioned at the feeding point of the unit. Any metal that could potentially contaminate the regrind, or damage the granulator or the injection molding machine, is captured by a high intensity magnetic plate.
ET series: extrusion solutions for recycling processes
CMG Granulators presents the ET2 configuration applicable to a vast range of models to recycle the trimmings from the extrusion line at the source of them. The high precision of assembly of the cutting chamber allows the granulation of the thinnest trimmings, obtaining the highest degree of regrind quality (homogeneous particle dimensions and absence of dust), efficiency of operation, ease of cleaning and the best application flexibility.
G17 series: Utmost application flexibility and precision cutting
The new CMG series of G17 granulators is designed to obtain the most homogeneous regrind shape and dimensions, along with little to no presence of dust. One additional very unique benefit of this new line is the ability to produce regrind with very small dimensions. The great advantage of dimensionally small regrind is the possibility to add higher percentages to the virgin material with no influence to the quality of the finished product. Small capacity systems, injection moulding machines or extruders, are equipped with small diameter plastification screws, unable to process granules with dimensions exceeding those of the virgin granule. The G17 granulators produce regrind which is dimensionally comparable to the virgin pellet.
