SHOT BLASTING TECHNOLOGY
Technical products require superior functionality and aesthetics in order to be successful in the marketplace. Rösler shot blasting systems offer you nearly unlimited options from deflashing, descaling, sanding and rust removal to roughening, matting, smoothing, edge rounding and shot peening.
There are few technical applications for metal surfaces that can offer the variety of uses that shot blasting technology can offer. Finishing of mineral components such as concrete and sandstone, glass, textiles, wood and plastics is all possible with Rösler machines.
Why Rösler Is Your Preferred Partner In Aerospace?
WIRE MESH BELT BLAST MACHINES
These machines are excellent for all-round, complete and continuous blasting treatment of flat as well as voluminous and very complex components.
With 4 or 8 high power Hurricane turbines, mounted around the housing (both vertically and horizontally inclined), it is also possible to treat very complex components, which have “pockets” or difficult to reach areas. A highly wear-resistant wire mesh belt, with tension adjustment, provides the part transport.
The special belt guiding enables the lower turbines to blast only through one belt position, which means that any masking is kept to a minimum.
These machines have three satellite turntable inserts (multiple table options are available upon request), each with a diameter of 1000 mm. These are integrated into the main table level, which has a diameter of 2500 mm. Once on the rotary disks, the components are blasted by high-performance Hurricane or Rutten turbines.
SPINNER HANGER BLAST MACHINES – SHOTBLASTING FOR BULKY COMPONENTS
Overhead rail shot blasting units are recommended for the treatment of sensitive parts which cannot be tumbled in bulk loads, and for particularly complex, heavy, or large parts. The parts are mounted on a hook and transported into the blasting chamber. The simultaneous rotating and oscillating movement of the hook ensures that the blasting media, accelerated by the multiple turbines, reaches every component, providing the best possible uniform blasting result. Rösler Overhead Rail units are very versatile units, and their compact design requires minimum floor space.
PRESERVATION LINES – PAINTING AND SHOT BLASTING SYSTEMS FROM ONE SINGLE SOURCE
A complete blasting and painting line consisting of individually adapted conveyor systems, a pre-heater, shotblasting machine, paint booth, and a post treatment dryer. Conveyor systems can be chosen according to individual requirements, together with roller conveyors, traveling grates, and cross transfer lines, etc. A gas-fired pre-heater unit allows the treatment of wet or even ice-covered material from outside storage. The paint layer produced in the paint booth will be dried in line by the post dryer unit, allowing the handling of the components immediately upon exit for further treatment steps. To reduce energy costs, the final drying process uses waste heat energy from the pre-heater.

Roller conveyor lines are an essential part of the overall preservation system. The components (plates, tubes or profiles) continuously pass through the pre-treatment chamber, the blasting chamber and the cleaning chamber, on a special roller conveyor. The high performance turbines mounted on the cabin housing ensure all-round coverage under controlled process conditions, and thus produce the desired cleaning effect.
TUMBLE BELT BLAST MACHINES
Mass-produced components, which can be tumbled, are ideal for processing in tumble belt batch machines, no matter what materials they are made from. Anything from small, delicate plastic parts to large, forged components, can be finished to the highest standard.
The batch system can be extended to a fully automatic system with the addition of peripheral loading and unloading equipment.
With the development of the RMBD continuously operating through feed tumble belt system, Rösler has set the highest level of standards for automated finishing of components. The system can be used for anything from high volume bulk components to components with complicated geometries. The high throughput of the RMBD makes this design very economical, and opens up possibilities for flexible production schedules. This gives you the potential for substantial cost savings, without sacrificing product quality or equipment reliability.
MULTI-TUMBLER – SMOOTH SHOT BLASTING OF BULK WORK PIECES
The central feature of the MT machine series is the geometry of the rotating barrel. The inside wall of the barrel features specially contoured ridges, while the bottom is shaped in the form of a three-sided pyramid. This unique design creates the innovative “multi-tumbling” action of the different barrel elements: when the drum rotates, the ridges on the internal wall of the barrel tumble and mix the work pieces. At the same time the pyramid causes the parts at the bottom of the barrel to move to the top of the mass. This multi-tumbling action ensures that the blast stream reaches all surface areas, thus producing even and consistent blast results. Brightly cleaned parts surface, free of sand, rust or scale, are achieved in short cycle times with an MT system with a highly consistent finish.
ROLLER CONVEYOR BLAST MACHINES FOR WELDMENTS –
CONTINUOUS PROCESSING OF COMPLEX WELDING CONSTRUCTIONS
These special roller conveyor machines for blast cleaning of complex welding constructions where all surfaces are cleaned. For example head- and base-plates, welded ribs and re-enforcements must be de-scaled and de-rusted. And the welding seams must be cleaned.
All-around blast cleaning of outer and inner surfaces takes place through 2 “blast zones”. The first “blast zone” consists of equally spaced blast wheels mounted onto the roof and bottom of the blast cabin – with larger machines there are also blast wheels mounted to the cabin walls. The second “blast zone” of blast wheels is placed at a negative angle relative to the direction of the parts transport. The blast pattern created by these two “blast zones” allows all-around blast cleaning of a vertically placed base-plate.
Typical areas of application: Steel and shipbuilding, mechanical engineering.
ROLLER CONVEYOR BLAST MACHINES –
CONTINUOUS PROCESSING OF LONG COMPONENTS
Roller conveyor shot blasting machines are mainly used for treating long and/or flat components. The components continuously pass through the “pre” chamber, the blasting chamber, and the cleaning chamber on a special roller conveyor.
Highly efficient turbines fixed on the machine housing make it possible to treat the components on all sides.
Rösler roller conveyor shot blasting machines are used to remove scale, rust and paint from long and/or flat components.
The RRB designed was fitted with our heavy-duty turbine system, which generates significant operating cost reductions due to faster throughput times, as well as reductions in shot-blasting media consumption and energy requirements.
SATELLITE TABLE BLAST MACHINES FOR
THE CONTINUOUS PROCESSING OF SENSITIVE PARTS
With the Rösler RSA 1400 indexing rotary table machine, gentle finishing of different kinds of components with no part-on-part contact is possible.
The entire spectrum of blasting applications ranges from delicate deburring up to shot peening. The installation is particularly interesting for applications in which the entire surface of the components need not be blasted, but only specific sections.
The RSA 1400 concept is based on a modular system and can be equipped with 6, 8, 10 or 12 satellites operating completely automatically.
These machines can be equipped with either injection or pressure blasting systems.
CONTINUOUS FEED LOOP BELT BLAST MACHINE
Rösler continuous flow shot blasting machines are ideally suited for treating small, high-volume bulk components. The special design of the V-shaped loop belt creates a screw-like movement of the parts through the machine, ensuring homogenous treatment of all parts. Another advantage of this loop belt conveyor system is to enable supply and extraction systems for a continuous flow of components of upstream and downstream processes.
BLAST CABINETS – MULTIFUNCTION SHOT BLASTING MACHINES
Blast cabinets are ideal when a variety of small parts is to be treated. The cabinets can be equipped with turntables, baskets, blast nozzles, pressure blasting systems, oscillators and other special auxiliary equipment, making them very versatile. The full-width front-opening door provides clear access to the complete blast chamber and the special design prevents blast media spillage when opened:
Pressure and injector blast cabins are used for:
- cleaning,
- deflashing,
- surface finishing,
- decorative blasting.
The range of shot blast media that can be used covers all non-hygroscopic media from very abrasive materials (e.g. aluminium oxide or silicon carbide) to plastic media and corn cob.
TURNING CHAMBER BLASTING MACHINES
The RWK features manual or fully automatic material handling in parallel with an ongoing blasting process, significantly reducing costly auxiliary process times.
The turning chamber blasting machine is the ideal blasting solution for cleaning, deflashing and peening a wide variety of work pieces, such as; cylinder heads, engine blocks, springs and automobile industry frame components.
TURNING TABLE BLASTING MACHINES
The RWT is a space-saving blasting machine that can be fully automated with any corresponding handling devices. The work pieces (e.g. transmission components, gear wheels, shafts…) are delivered to a rotating satellite for processing. The horizontally and vertically traveling blasting unit guarantees an optimal and repeatable blasting outcome. Extensive options are available for process monitoring (e.g. blasting abrasive quantity, pressure regulation…)
