Used Rieter Automatik Equipment Sold by Meadoworks

The company behind Rieter Automatik traces its roots to 1947, when it was founded in Grossostheim, Germany as Automatik Apparate und Maschinenbau. Rieter Group, the Swiss industrial conglomerate, acquired the business in 1992 and renamed it Rieter Automatik GmbH, giving the pelletizer maker access to a global sales and service network. Rieter Automatik quickly grew into one of the world leaders in plastics pelletizing machinery, with roughly 230 employees and annual sales of approximately CHF 70 million at its peak. Rieter Group divested the business in January 2008, and the company later reverted to the Automatik name before eventually becoming part of the Maag Group.

Rieter Automatik built its reputation on a broad range of strand pelletizing equipment. The ASG series of strand pelletizers became an industry workhorse, offered in multiple rotor widths and featuring helical rotors, power roller feed systems with pneumatic tension control, and capacities ranging from a few hundred to over 14,000 pounds per hour. The Primo S series strand pelletizers, available in 100 mm and 300 mm rotor widths, emphasized high flexibility and consistent machine availability. The USG series covered underwater strand pelletizing in both horizontal and vertical configurations, while the ATG series handled automatic dry-strand pelletizing with integrated water separation and air-knife drying.

Rieter Automatik strand pelletizers and underwater pelletizing systems were designed for the full spectrum of polymer and plastics processing. Core end markets included polymer compounding and masterbatch production, PET and PBT resin finishing, engineering plastics such as nylon and polycarbonate, polyolefin production, plastics recycling, and specialty chemical pelletizing. The equipment also found use in pharmaceutical and food-grade applications where precise, uniform pellet geometry and hygienic construction were required.

Used Rieter Automatik strand pelletizers remain in strong demand on the secondary market for several reasons. The ASG and Primo S series were engineered for long service life, with robust helical rotors, stainless steel contact surfaces, and straightforward mechanical drives that are easy to maintain and regrind. Replacement blades, rotors, and feed roll components have remained available through the successor Maag Automatik organization, reducing downtime risk on older machines. Buyers seeking used Rieter Automatik pelletizers typically cite the combination of proven German engineering, wide throughput range, and the ability to process demanding engineering resins as key reasons these machines hold their value decades after manufacture.
