Cutting-edge Rutten Gamma turbines from Rösler deliver higher efficiency, lower energy consumption, and longer service life for a leading German saw band manufacturer.
A leading manufacturer of saw bands has significantly improved equipment availability and blast performance by investing in ultra-modern turbines from Rösler. The company chose the Rutten Gamma 330-HD high-performance turbines for its belt shot blast machine not only for their extremely wear-resistant design but also for their 25 % higher blast performance with, at the same time, lower energy consumption.
The manufacturer, renowned worldwide for its precision steel strip products, maintains all production in Germany to ensure exact edge dimensions and perfect flatness, despite exporting around 90 % of its output. A critical stage in its manufacturing process is shot blasting, carried out in a belt blast machine supplied by a Southern European manufacturer, which had become in urgent need of modernisation.
Based on the detailed process parameters provided, Rösler developed a tailored technical concept and submitted a quote for retrofitting the existing machine with two Rutten Gamma 330-HD turbines, each with 7.5 kW power, matching the original turbines. Extensive trials in Rösler’s Customer Experience Center using actual customer workpieces confirmed the feasibility of the solution.
The Rutten Gamma turbines’ high performance derives from their innovative design, featuring four Y-shaped throwing blades with precisely calculated curvature. This ensures optimal acceleration and delivery of the blast media at maximum throwing speeds, significantly improving shot blast efficiency compared with conventional turbines. The upgrade boosted the machine’s blast performance by approximately 25%, delivering a substantial increase in shot blasting capacity, while simultaneously offering up to 25 % savings in energy consumption.
Durability is another standout feature: the throwing blades are made from an extremely wear-resistant steel alloy and can be used on both sides, depending on the media employed. As a result, the Rutten high-performance turbines achieve a service life 10 to 16 times longer than conventional turbines. Combined with Rösler’s reliable and rapid spare parts service, this translates into significantly higher equipment uptime and lower maintenance costs.
The turbine replacement on the existing machine required only minor adaptation to the original mounting flange, with no further modifications needed. During installation, Rösler engineers worked alongside the customer’s maintenance team to fine-tune the machine for its new performance levels, including the addition of wear plates to the blast chamber.
“One year after installation, we are extremely satisfied with the Rutten high-performance turbines. Encouraged by these results, the manufacturer now plans to modernise additional blast machines across its operations,” has confirmed the customer.
