Blade Technology: Straight vs. Curved Blades Explained

As an expert in the shot blasting industry, Rosler knows about blade technology. All shot blasting machines require blades to propel media towards workpieces. While both straight and curved blades are used, each type offers advantages and disadvantages.

What are the Differences?

Straight blades are, as the name suggests, blades that do not have curvature when viewed from the side and do not possess tangential curvature with respect to the turbine. Curved blades are blades that have some degree of curvature when viewed from the side.

As the newer design, curved blades are generally better than straight blades, but they also have some drawbacks related to longevity, maintenance, and cost of ownership.

How To Ensure You Get The Maximum Performance Out Of Your Blast Turbine

Rutten “C” and “Y” Blast Wheel Turbines

The Long-life Rutten has the longest ultimate life expectancy of any, lasting upto 20 times longer than a standard blast wheel or turbine.

This is a highly-engineered blast wheel with exceptionally tight tolerances and built-in specialist superior steel alloys.  Due to the higher value materials and the high specification machining costs of these materials, the initial investment and cost of component wear parts are more highly valued.

However, if maintenance and/or production problems are presently a big issue, the economics of this blast wheel can be demonstrated in ultimately high production speeds and demanding applications.

Least Maintenance And Highest Specifications

Less costs for maintenance up to 16 times higher wear resistance and service life of up to 40,000 operating hours (over 18 years on a single shift).

The proven Rutten Long-Life turbines, equipped with components made from carbide steel are characterised by their extremely long service life of up to 40,000 operating hours resulting in significantly higher equipment uptimes and drastically reduced time requirements for maintenance.

They offer substantial savings in energy consumption and spare part costs/hour. The blades have a precise design with a high recognition value and in addition allows the “Y” blade to be turned and used twice. Long-Life turbines are installed in a wide range of new shot blast equipment and can be easily retrofitted into existing shot blast machines.

PART 1             The Case for Superior Blast Wheel / Turbine Efficiency

Your blast wheel is the “business end” of you shot blast machine.   It is the main component which delivers the blast media and performs the blast cleaning or peening process.rosler-gamma-y-wheel

Its performance is vital!

Not only is the blast wheel vital, it is probably the more expensive single item on the machine in terms of performance, productivity, time, maintenance, repair and wear part costs.

PART 2   The Case for Superior Blast Wheel / Turbine Efficiency

Less energy consumption up to 25% cost-savings and compliance to environmental policy.

Depending on the size and type of shot blast process i.e. type of machine – Table, Hanger, Barrel, or Through Conveyor, the cost of running per hour adds up.

A simple small table or hanger machine may pull between 11 amps to 60 amps / blast wheel.  A single blast wheel will require 5.5kW to say 30Kw.  Using a nominal 10p / kW hour, costs range from 55p to £3.00/ blast hour x 2,200 hours / annum equates to between £1,210 and £6,600.

 PART 3         The Case for Superior Blast Wheel / Turbine Efficiency

Our / Your Aims

To reduce to a minimum the amount of maintenance labour required on the blast wheel.  By placing superior quality spare wear parts into the blast wheel, that will sustain and maintain the blast pattern between 2 and 20 times longer, depending on your application, choice of blast wheel and abrasive type employed.

Reduce the number of wear parts required to be purchased per annum, by making the spares of higher quality material and design, which wear at a much slower rate, and maintain their integrity for very much longer.
