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.
New EV 92-220: Advanced Granulation Systems for a New Era of Post-Consumer Plastics Recycling
In an era where sustainability and operational excellence are paramount, CMG Granulators introduces its EV Evolution Series, the next-generation line of granulation systems engineered specifically for post-consumer plastics. With a direct focus on energy efficiency, performance, and innovation, the EV Series sets a new benchmark in plastics recycling technology.
At the heart of this evolution is CMG’s proprietary design philosophy: delivering maximum throughput with minimum environmental footprint. Each EV Series model is optimized to reduce energy utilization by up to 50% compared to conventional granulators, achieved through advanced cutting geometries, unique rotor design, and intelligent drive systems. These design advancements provide the highest energy efficiency and the lowest total cost of ownership (TCO) of the category.
Ease of maintenance is another cornerstone of the EV Series. Featuring simplified/quick access to key mechanical components, self-lubrication systems and predictive diagnostic capabilities, the machines minimize downtime and make operational procedures easy and simple to implement. Every granulator in the series is built with operator safety and accessibility in mind.
The EV Series is also unmatched in terms of output. With processing capacities ranging from hundreds of kilograms to several tons per hour, the series is versatile and scalable for applications across post-consumer rigid and flexible plastics. Equipped with a unique cutting chamber having proprietary CMG design, these granulators ensure clean, dimensionally consistent regrind, no powder or micro particles and the highest yield.
This year’s highlight at K2025 is the global debut of the EV 92-220 model, the largest and most powerful granulator ever introduced in the industry. Designed for heavy-duty applications and massive volume streams, the EV 92-220 features a revolutionary cutting chamber architecture and advanced control integration, for enhanced reliability under extreme operational loads. With an output capacity that exceeds any existing machine in the marketplace, it is the definitive solution for large-scale plastics recycling plants seeking both scalability and efficiency.
The EV Series represents a bold leap forward in sustainable plastics processing. By combining breakthrough engineering with operational simplicity and unmatched performance metrics, CMG Granulators continues to lead the change toward a more circular economy.
"The launch of the EV 92-220 marks not only a technological milestone but a statement of intents, a commitment to transforming waste into value at scale" Santella concludes.
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 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.
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.
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.
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.
