CYM Materiales SA offers a wide range of turbine models according to the need of each customer. Blast wheel shot blasting is the most economical method among the current cleaning techniques, as well as the one that minimizes environmental impact.

The shot blasting principle is based on the use of kinetic energy from the abrasive used when it impacts the surface of the piece, removing impurities.

The performance of the equipment depends on the quality, quantity, speed and direction of the shot; these last three factors depend entirely on the correct operation of the blast wheels.

The wheel is the heart of the machine, and has decisive influence on the effectiveness of the work performed, the appearance of the blasted surface, the production costs and thus the profitability of the process.

Operation Principle:

• The operation of blast wheels is similar to that of a fan or a centrifuge pump.
• The wheels throw the abrasive through centrifugal force in a determined direction,speed and amount.
• The abrasive enters the wheel through the down comer elbow or feeding bushing, from the storage hopper.
• The impeller provides an initial acceleration of the shot, pushing it through the opening of the control cage. Then the shot continues toward the vanes or blades.
• The shot is thrown by the latter, through centrifugal force, until it reaches the pieces to be treated.
