Rösler Hurricane®-Turbines
Blast Turbine Hurricane®
Blasting media is fed through a central feed tube into the high speed rotating turbine. The centrifugal force, of
the rotating turbine, throws the media at the components to be blasted at speeds of up to 120 m/s. The design
of the blades, insertion point, and the speed of the turbine determine the processing results in conjunction with
the blasting media. In order to achieve an economic utilization of the blasting media, the amount of blasting
media and the transfer to the turbine blades can be easily adjusted. The blast media flow is either fixed or can
be adjusted automatically through the PLC/control panel. A clam shell valve controls the media flow from the
media hopper to the turbines. The blast pattern – e.g. position of the hot
spot – can easily be adjusted from outside of the turbine. The turbine
speed can be adjusted with a frequency
inverter thus allowing gentle or very aggres-
sive blasting.

Rösler dust collectors incorporate the latest dust extraction and collecting
technologies. Rösler offers a dust collector for every conceivable blast
application. All Rösler dust collectors are in full compliance with govern-
mental safety regulations. As required, they can be upgraded to handling
combustible dusts (explosion-proof systems).
Two different systems – wet or dry collectors – can be offered
Frequently dry collectors are equipped with a fine filter “Police filter“.
Residual dust load < 0.5 mg/m³.
The standard “backpack” filter on the blast machine reduces the space
requirements by up to 10 m². The short air ducts contribute to a greatly

automatic preservation lines. upper and 4 bottom turbines) for blast
cleaning of Plates and Profiles.
RRB 16/5
For blast cleaning (de-scaling, de-rusting) of Plate & Blast cleaning of welding constructions

Special roller conveyor machines for blast cleaning of complex
Welded fabrications and constructions; where all surfaces are
required to be cleaned. For example Head- and base-plates,
welded ribs and re-enforcements must be de-scaled and de-
rusted. The welded seams must be cleaned of weld scale and
acidic flux.
All-around blast cleaning of outer and inner surfaces are achieved
through 2 “circular blast zones”. The first “blast zone” consists
of equally spaced turbines mounted in a circular convex fashion
onto the roof and bottom of the blast cabin – with larger machi-
RRBK 22/11 nes there are additional turbines mounted to the cabin walls.
Special version with greater pass height. Special
chamber end covers prevent media spillage.
Alternatively the second “blast zone” of turbines are placed at
an angle relative to the direction of the product transportation.
The blast pattern created by these “blast zones” allows all-around
blast cleaning together with leading and trailing ends.
Preservation lines
Rösler roller conveyor blast machines can be upgraded to complete preservation lines (Pre-heater,
blast machine, paint booth, dryer). These lines are complemented by customer-specific component
transport systems.

For Rösler service is not just an empty promise
Professional advice, short turn-around times and prompt and reliable
service: Rösler offers single-source surface finishing solutions, world-
wide!
4 Installation and training
Machine installations and operator training are performed by
our team of highly skilled and experienced service engineers
4 In-House Manufacturing
In line with our corporate philosophy to be a true “single source”
supplier, Rösler engineers and manufactures all equipment components such as
vibratory motors; load/unload systems, control panels, welded constructions,
laser cut parts, etc., in-house.
4 Spare parts service for all recognized shot blast systems
Surface finishing equipment generally is subject to a considerable amount of
wear. For this reason preventive maintenance and prompt supply of spare parts
are a key requirement for any surface finishing installation. Rösler maintains a
complete inventory of spare parts in every branch, ensuring local supply and
fast availability, be it wire mesh belts, turbines, pressure vessels or any kind of
nozzles, etc. To minimize downtime, parts are either delivered and installed by
our own field service personnel or shipped to our customer’s location overnight.
4 Maintenance and repair service
Rösler maintains a well trained staff of
professional field service engineers providing
prompt, reliable maintenance and repair
service as well as overhaul of your older
equipment.
