CMG presents the new Regrind Evac Systems range of evacuation, dedusting and powder containment system solutions, as well as the brand new G55-120 model granulator, at the Ecomondo trade fair, in Rimini, Italy, from November 5 to 8.

New Regrind Evac Systems range

The new Regrind Evac Systems unit is one of the largest of its category, which can evacuate, convey, dedust regrind of up to 7,000 kg/h. The entire new range 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 – 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 include avoiding generating any dust or small particles by friction against the conveying pipe walls, as well as avoiding the impact against the blower impeller blades, utilized on conventional blow-thru evac systems.

The regrind is then deposited in silos, octabin 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.

This new system guarantees zero pollution 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.

New G55-120 model granulator

At the Ecomondo trade fair, CMG also launches its new G55-120 model granulator, featuring new state-of-the-art cutting chamber design and an integral evacuation system composed of receiver cyclone with built-in dedusting chamber and air/powder automatic filtration system.

The new cutting chamber design features a new rotor configuration allowing 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. 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, which the mass of material being ground in the cutting chamber does not rotate with the rotor producing lots of dust and fine particles.

The granulator is suitable for recycling applications as well as injection molding, blow molding and extrusion as well as the EV916 granulator unit, one of the largest granulators in its category, with an hourly capacity of 6,500 kg.
