MAAG Group upgrades Primo E strand pelletizers for small batches

MAAG Group has upgraded its strand pelletizers, the Primo 60 E and Primo 120 E. The machines were designed to meet the challenges faced by masterbatch manufacturers and flexible compounding processes. With frequent colour and formulation changes as well as small production batches, the system is intended to maximise equipment availability by significantly reducing downtime.

In modern plastics processing, increasing product diversity and smaller batch sizes are the norm. The cost-effectiveness of a plant therefore depends heavily on how quickly it can return to operation after a product change. A key feature of the Primo E series is the single-sided mounting of the cutting rotor. This open design gives operators quick access to the entire cutting chamber, which simplifies cleaning and minimises the risk of material carryover or colour contamination in subsequent batches.

"With the PRIMO E series, we achieve the highest possible efficiency during frequent product changes," explains Alexander Helm, Product Manager for Strand Pelletizing at MAAG Group. "Our customers benefit from a design that reduces unproductive downtime to an absolute minimum. Instead of hours-long changeovers, we ensure maximum flexibility while maintaining consistently high pellet quality – a real competitive advantage for small batches and frequent product changes."

Quick change for over 150 configurations

The cutting tools and feed rollers can be replaced simply and quickly. To respond to a wide variety of material properties, ranging from soft and elastic to highly filled and abrasive, MAAG offers more than 150 cutting rotor variants, as well as matched counter knives and feed rollers. Materials such as chrome tool steels, cemented carbide or powder-metallurgical steel ensure consistently high pellet quality and long service life.

Two performance levels

The very short, unguided length between the feed and the cut ensures precise strand cutting. An optional dual-drive variant allows stepless adjustment of pellet length and weight. The systems are available in two sizes with strand feed speeds of up to 120 m/min:

• Primo 60 E: 60 mm working width, 2.2 kW motor power.
• Primo 120 E: 120 mm working width, 4.0 kW motor power.

Both models can be integrated into complete MAAG strand pelletizing lines. According to the company, the system shows that modern pelletizing technology is defined not only by throughput but also by overall efficiency and flexibility in day-to-day production.
