Granulators and Shredders for Recycling
Waste recycling and the recovery of materials are ever more important in the world economy.
CMG considers recycling an important economical aspect which, with over forty years of experience in manufacturing high-quality granulators and shredders, can offer excellent machinery for scrap recovery.
CMG granulators and/or shredders are used for the industrial recycling of several post-consumer materials such as: plastic, used bottles, wood waste, paper and documents, electric cables, fabrics, film, tyres, etc.
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.

Robustness and automation at the highest levels
CMG provides technologies and solutions designed to meet all the unique and innovative demands of the Circular Economy. The post-industrial and post-consumer recycling processes have renewed connotations that aim at the reintroduction of recycled materials in the production processes on large scale. CMG's solutions for the world of recycling include granulators, shredders, integral feed conveyors, evacuation and regrind transport systems, dedusting units, dust management and air filtration. CMG's installed base is considerable: over 45,000 units supplied to its customers in the company's 46 years of activity.
Supergranulators 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.
Operating efficiency at the highest level: Adaptive Motor Power
All CMG units for Recycling applications, with capacities from 800 kg/h to over 5,000 kg/h, feature the Adaptive Motor Power (AMP) function, unique in the size reduction industry. The granulator is able to autonomously establish which power level to adopt to carry out its work, according to quantity of material to be ground, shape, weight, thickness, type of plastic, and temperature of the piece. The AMP allows to optimize the quality of the regrind material to the maximum (dimensional and physical homogeneity of the regrind particle and absence of dust) and minimize the use of electricity. From 20 to 25 Wh/kg is the small amount of energy that a CMG granulator uses, compared to over 50 Wh/kg that a conventional unit consumes. The ROI for the AMP is less than 12 months.
SUBCATEGORY
FILM
Grinding of bulk or reels of film obtained by extrusion is entrusted to special granulators and shredders manufactured by CMG.
During this process the film, made of polyethylene, is obtained through extrusion. Namely, the PVC mixture enters the cylinder hopper and, after having been heated progressively, melts and is transported towards the outfeed hole.
Passing through this flat shaped hole produces film or laminates of different consistency and thickness. The material used in this process is essentially LDPE.
The range of granulators and shredders is available:

ELECTRIC CABLES
The grinding and size reduction of electric cables is entrusted to granulators and shredders which CMG supplies to companies specialised in recovery of electric cables, processing scrap, copper pipes and nonferrous materials coming from companies in the electric sector or industrial and civil demolitions and dismantling.
This recovery saves money, allows the recycle and reuse of a large amount of waste and keeps potentially dangerous materials from being released into the environment.
During the grinding process, the cable undergoes a first shredding process to achieve size reduction and iron removal. Then the granulator creates ground material composed of plastic and copper which can undergo a subsequent dry separation of the metal from the insulating plastic by means of magnetic separators.
