pumps, screen changers, and pelletising systems with Fimic’s know-how and established network within the Italian plastics industry, to deliver techni- cal support, streamlined sales channels, and innova- tive solutions tailored to the specific needs of Italian processors. Sven Conrad, BKG’s Global Segment Development Director at Nordson, said: “Fimic’s strong industry connections, technical expertise, and dedication to customer satisfaction make them the ideal partner to represent the Nordson BKG brand.” Erica Canaia, Fimic’s CEO, said: “Fimic has long been committed to providing our customers with the highest quality and most efficient filtration solutions. Adding Nordson’s BKG renowned products to our portfolio allows us to offer a more comprehensive, end-to-end solution and elevate process efficiency for our customers.” At the same event, Erema’s Powerfil business

unit presented the new DischargePro control system. Recycling post-consumer input material is often characterised by material inconsistencies leading to fluctuations, presenting a major chal- lenge for recycling companies. With the SW RTF backflush filter and its laser filter, Erema offers two filters in different sizes, designs, and with varying performance levels. The new laser filter control system detects significant changes in throughput and automatically adjusts the discharge rate so thickening remains consistent during filtration. By adjusting the speed of the scraper disc and the discharge screw, the DischargePro ensures the melt thickens uniformly, a crucial parameter for a consistent and cost-effective process. “The new DischargePro control system automati- cally determines the optimum process setpoints
and ensures that these are maintained during the whole operating period,” said Robert Obermayr, Head of Erema’s Powerfil business unit. “This is made possible using fully automatic reinitialisation which is time and/or event driven.”
Contamination
The DischargePro deals with contamination peaks by
automatically adjusting the speed of the scraper star and returning it to the setpoint speed as soon as the contamination peak has been discharged. It also automatically adjusts the setpoint value to ensure a consistent discharge rate and takes the ongoing condition of the filter screen into account. Over the course of the screen’s utilisation period its effective surface area systematically decreases, increasing the pressure drop even though the input material is still the same. “Our new laser filter control system delivers
greater efficiency and more stable processes for our customers and is particularly user-friendly,” said Obermayr. “We have been able to achieve up to 50% lower melt losses for our customers compared to the previous Erema laser filter control system.” At last year’s NPE, Britas presented its Automat- ic Belt Melt Filter (ABMF) with two filter heads for powerful, ultra-fine filtration. The ABMF-TH boasts low melt loss with high output – with efficient melt filtration, flexibility and safe operation. With a screen area of up to 3,200 sq cm, Britas customers have achieved a throughput of up to 8,000 kg/h with a filtration fineness between less than 40 microns and 1000 microns. Melt loss is less than 1% for polyolefins, says the company. Last summer, ADG Solutions, a distributor for
Break Machinery which recently moved to a larger facility in Stone Mountain, Georgia, US, introduced the Duo double-filter system to the North American market. The Duo is equipped, as its name suggests, with two perforated discs (breakers), which increases the filtering area and production volume. The scraper disc, placed between the two filters, has blades on both sides and rotates to remove contami- nation from both surfaces while its geometry prevents these contaminants re-entering the melt. The filter surfaces are constantly cleaned so that they can be used for longer periods than with conventional systems, and the two filter approach makes it possible to reduce the size of the filtration
