In the Spotlight

For over 90 years, the privately owned Rösler Oberflächentechnik GmbH has been actively engaged in the field of surface preparation and surface finishing. As a global market leader, we offer a comprehensive portfolio of equipment, consumables, and services for mass finishing and shot blasting technologies across a wide spectrum of industries. Our range of approximately 15,000 consumables—developed in our Customer Experience Centers and laboratories around the world—enables us to meet our customers’ individual finishing needs. Under the brand name AM Solutions, we provide a wide variety of equipment solutions and services in the field of additive manufacturing/3D printing. Last but not least, as our central training hub, the Rösler Academy offers practical, hands-on seminars on the topics of mass finishing, shot blasting, and additive manufacturing. The Rösler Group operates a global network of 15 locations and approximately 150 sales agents.

Retrofit of Shot Blast Machines – Brand-New Equipment Is Not Always Required. Secure spare parts supply and improved blast performance — these were the reasons why a manufacturer of saw bands invested in ultra-modern new turbines for a belt shot blast machine. The customer chose the Rutten Gamma 330-HD high-performance turbines not only because of their extremely wear-resistant design, but also because he was impressed by the 25% higher blasting performance combined with lower energy consumption. In the meantime, the customer has decided to equip other blast machines in his manufacturing organization with high-performance turbines from Rösler.

The saw bands produced by this company are known worldwide for their superb quality. These steel strip products offer excellent precision, for example, exact edge dimensions and perfect flatness. To maintain its quality standards, the company manufactures all its products in Germany, even though around 90% are exported to other countries. A key stage in the manufacturing process is a shot blasting operation in a belt blast machine.

Improved shot blast performance and secure spare parts supply

The machine used for this shot blast operation, supplied by a manufacturer in Southern Europe, urgently needed to be modernized. Therefore, the engineer responsible for streamlining manufacturing operations discussed the customer’s requirements with the Rösler team during a visit to the Deburring Expo exhibition. The focus of this conversation was not only a secure spare parts supply and first-class technical service, but also improved blast performance to achieve a higher workpiece throughput. Based on the detailed process parameters provided by the customer, Rösler developed a technical concept and submitted a quote for retrofitting the turbines on the existing blast machine. The quote included the installation of two high-performance Rutten Gamma turbines, type 330-HD, each with a power of 7.5 kW. This corresponds to the power of the original turbines. The feasibility of the offered turbines was verified through extensive processing trials in the Customer Experience Center at Rösler using the actual customer workpieces.

Faster blast cycles with lower energy consumption and reduced wear

The high performance of the Rutten Gamma turbines is based on their special design. They contain four Y-shaped throwing blades with a precisely calculated blade curvature. This ensures extremely precise blast media acceleration and delivery at maximum throwing speeds and, compared to conventional turbines, significantly improves shot blast efficiency. The new turbines increased the blast performance of the existing shot blast machine by roughly 25%, resulting in a substantial increase in overall blasting capacity. Moreover, the efficient blast media delivery provides energy savings of up to 25%.
The throwing blades are made from an extremely wear-resistant steel alloy, and their special design allows the use of both blade sides. Therefore, depending on the blast media used, the Rutten high-performance turbines provide a 10- to 16-fold increase in service life compared with conventional turbines. These technical features, combined with the reliable and fast Rösler spare parts service, ensure significantly higher equipment uptime while simultaneously lowering maintenance costs.

Quick turbine exchange and optimization of the entire shot blast machine

The turbine exchange on the blast machine, originally supplied by another manufacturer, was completed within a relatively short time. Apart from a minor adaptation of the original mounting flange, no additional modifications were required. At the same time as the turbines were replaced, the customer’s maintenance team and Rösler engineers fine-tuned the existing shot blast machine to accommodate the higher blast performance. Among other measures, the blast chamber was lined with additional wear plates.
About one year after the new turbines were installed, this saw band supplier is extremely satisfied with the Rutten high-performance turbines. Therefore, he plans to modernize additional blast machines in his manufacturing organization that were supplied by the manufacturer in Southern Europe.
