Centrifugal Shot Blast Turbines

The centrifugal blast turbine is the heart of any turbine blasting machine and the factor with the greatest influence on work effectiveness, surface quality and machine operating costs. Its function is to project abrasive by centrifugal force in a defined direction, velocity and quantity: the overall performance of the machine depends directly on the correct operation of each turbine. Machines can mount multiple turbines positioned so that abrasive reaches the entire surface of the parts, achieving the desired surface finish in a single pass and at the required production speed.

CYM Materiales develops and manufactures its own centrifugal turbines with over 50 years of experience in industrial blast cleaning. The housing is made from manganese steel sheet with a high-chrome cast iron internal lining and a locking/interlocking system that forms a double wear-resistant wall. The control box positioning and locking system guarantees that the operator always assembles the component in the correct position during maintenance, preventing incorrect hot spot adjustment that would cause premature wear, production loss and deterioration of blasting quality. The turbines accept mounting in any position — including vertical axis — and feature bidirectional rotation without the need to modify blades or wheels.

The CYM range comprises seven centrifugal turbine models with wheel diameters from 166 to 600 mm, admissible powers from 4 to 150 HP and flow rates from 40 to 1,500 kg of abrasive per minute at outlet velocities of 50 to 110 m/s. For the TR-250, TR-300 and TR-360 models, two wheel options are available — cast monoblock or machined with interchangeable blades — each with specific advantages in maintenance, operating cost and projection performance. Three blade widths (narrow, standard and wide) and five control box apertures (25°, 30°, 40°, 50° and 60°) complete the configuration for each application.
