Rotary Head For Complex Geometries

Rotary Blast Head Equipment

In many applications, parts that require cleaning will have complex geometries in the design of the part. This becomes a challenge to achieve a clean part due to many angles and areas that can trap contaminants.

Continuous Processing

An example of a common application with complex geometries is cleaning airfoils. These airfoils are typically 3-4 vanes made into a single fabricated piece.  The pitch of the blades and the proximity to each other makes it difficult to access all of the different faces.

The main blast cleaning technologies that are used in this application include linear oscillators and swing arm oscillators. In a linear oscillator, the part gets hit only one time. With swing arm oscillators the arm travels in an arc and goes left and right, still only getting one pass and hit at one angle.

However, by using a rotary head you get two passes under the guns; one on the leading edge and one on the trailing edge. This doubles the exposure time and the number of angles, plus the rotary head is rotating so you achieve complete 360 degree coverage.

Other applications where rotary heads work well include cleaning turbine blades, bucket and vanes. All of these components have complex geometries and require multiple angles for complete cleaning.

Airfoils in the cleaning process

Empire is ready to help determine the best solution for your application. The company has a process in place to move from concept to installation in about 10 to 14 weeks. We are able to process sample parts in the demo lab utilizing different methods and technologies. Customers are able to be on-site to see the exact results.

Once a solution is developed the quote with pricing is developed. Upon approval a drawing is submitted to fit the plant space and specifications. After any changes, when machine is built and ready, parts and media are sent in for testing in the new machine for customer approval. Then the new unit is shipped and installed, with technical assistance for startup and operator training.
