GRANULATORS | TECHNOLOGY
Granulator groups are developing larger machines,
combination technologies and energy-efficient models in response to the changing recycling environment. Chris Saunders reports on new trends and products
More than just size reduction
Manufacturers of granulation systems are not resting on their laurels, but instead are moving ahead with innovations that give consideration to energy efficiency, granulate quality, system integration and more. The latest equipment is also safer and easier to operate, and there is increased demand for more durable parts and materials, all of which feeds into an over-reaching commitment to boost profitability by cutting costs wherever possible. Energy consumption has come to the fore in
recent times, especially in Europe, and manufactur- ers are keen to minimise electricity usage to make their machinery more appealing to customers who can then factor the savings in to their bottom line. To this end,CMG Granulators says all its units with capacities from 800 kg/h to over 5,000 kg/h are equipped with the Adaptive Motor Power (AMP) function, which the company says is unique in the size reduction industry. In essence, AMP means the granulator can independently determine which power level is most applicable to the job at hand, depending on the

amount, shape, weight, thickness, type of plastic and temperature of the material to be ground. The AMP not only reduces the amount of electricity being used, but improves the quality of the regrind material, guaranteeing dimensional and physical homogeneity of the particles. By way of comparison, a CMG granulator uses only 20 to 25 Wh/kg, compared to around 50 Wh/kg consumed by a conventional unit, says the company. The return on investment is said to be less than 12 months. At Plast 2023, CMG presented the EV916 and EV616 models from its Evoluzione series of post- consumer waste granulators, suitable for the most critical operating conditions, for wet or dry granula- tion, with granulation capacity from 2,000 to over 5,000 kg/h. CMG has introduced a brand new cutting chamber design for its Evoluzione granula- tors. 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
