CMG Granulators will take part at the Plastics Recycling World Expo North America 2024 to be held on 13^th and 14^th November in Cleveland, OH (booth E842).

Don't miss the speech by Giorgio Santella, CEO of CMG Granulators, on 14^th November at 10:10 am in the Plastics Recycling World Expo Theater to learn all about innovative high-capacity granulation systems for post-consumer plastics recycling.

Innovation & Performance: New cutting chamber design

CMG Granulators 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.

Continuous Improvement & New Developments: New Evacuation & Dedusting Systems

Along with its state-of-the-art granulator design, CMG Granulators is introducing a brand-new development: the new range of evacuation, dedusting and powder containment system solutions. The unit is the largest of the category and can evacuate, convey, dedust an amount of regrind of up to 7.000 kg/h. The entire new range of the so called Regrind Evac Systems, starts at a capacity of 200 kg/h and, through a selection of 10 different sizes, reaches the impressive capacity of 7.000 kg/h.

The new evac systems operate under full vacuum, meaning the regrind material is evacuated from the granulator and is gently conveyed to a cyclone receiver and through a dedusting chamber, all of that under negative pressure. The advantages of using negative pressure are several, from not generating any dust or small particles by friction against the conveying pipe walls, to avoiding the impact against the blower impeller blades, utilized on conventional blow-thru evac systems. The regrind is then deposited in a storage bin, gaylord or big-bag while the powdery air is handled by a purposely designed automatic self-cleaning filter unit. The powder collected at the filter unit is automatically compacted and deposited/boxed for recycling or disposal. The complete system guarantees ZERO pollution to the environment and the degree of filtration of the air from the filter station can be adjusted in respect to local regulations or specific requests.

All new system solutions supplied by CMG Granulators will be equipped with the new Evac Systems, that are also offered as upgrade kits for existing/legacy granulation systems, CMG and non-CMG.

As all machinery and equipment supplied by CMG Granulators, the new line of Regrind Evacuation Systems is entirely designed, produced and assembled at the CMG production premises in Italy.
