North America, as reason for recent significant growth. “Through extensive conversations with our customers we determine market directions and what technology developments are important to the end-users,” says Jim Forgash, Vice President of Sales at the company. Forgash says the company continues to make minor but effective improvements to increase the cost-effectiveness of its equipment, particularly as it attempts to move into more markets around the world. He cites examples such as a new diamond bed knife, fine-tuning of Bay’s micro-pelletising system, and a cleaning assist option in the pelletiser cutting chamber. “We offer a standard platform of pelletisers, but everything is tailored to each customer’s requirements,” he says. “Every machine has a different infeed height, discharge height, discharge chute…that’s how we differentiate ourselves from our competitors.” Based on conversations with customers, the company has also continued to develop its Micro Pelletizing line. This allows customers to process products with pellet sizes down to 0.1 mm and with extremely consistent results, Forgash says. “We will also be introducing new technology that integrates a cleaning assist option to the cutting chamber of the pelletiser to reduce dust and fines in our cantilevered style pelletisers.” Forgash says this new cleaning assist function was requested by a European compounder that was unable to get its regular pelletiser supplier to develop a solution that met its needs.

year and the feature will now be incorporated as a standard feature on future lines for all customers. The development combines an air nozzle system
and a patent-pending vacuum technology to aid in cleaning the cutting chamber, reducing the amount of down time between material changeovers. The clean assist system can be added to existing pelletisers through the addition of the air components and a standalone PLC, or it can be used in conjunction with the company’s Digital Pellet Length control and can easily be programmed to change cleaning sequences as needed.
Simple operation At Polimer Teknik in Turkey, Sales and Marketing Director Reha Yelken says the company has achieved some good results with its Poex G Series strand pelletisers. It, too, aims to create individual customer solutions for lines processing a wide range of polymers and, to that end, Yelken says it offers many options. “Wear resistant and corrosion resistant designs exist depending on process demands. Also, Poex strand pelletisers provide easy operating and easy maintenance with their unique structures,” he says. Polimer Teknik offers six models in its Poex G
Series range, with operating widths ranging from 60 to 600mm and in versions capable of handling up to 150 strands. All run at line speeds between 30 and 70 m/min. Yelken says the units are very energy- efficient. They also provide easy operation and maintenance, with a design that allows simple access to the inside of the cutting chamber. In addition, the double drive design enables production of a wide range of different materials, he says.
Suction drying UK-based Accrapak now has a full range of dryers suitable for pelletising lines from 1to 60 strands. “We can offer a suction dryer for all the pelletisers in our production range,” says Technical Engineer
