Marathon Series Blast Turbines

Marathon C series Blast Turbines

Direct Driving Type Blasting Wheel And Blast Turbine

Direct driving type blasting wheel and blast turbine are compact blasting wheels and blast turbine in shot blasting machine. Motors and blast blast turbine are connected by shaft. So it is much higher efficiency and more quiet.

Max motor power is 15 kw and max blasting capacity is 250 kg per min.

Belt driving type blasting wheel and blast turbine

Belt driving type blasting wheel and blast turbine are most popular blast wheel and blasting turbine in shot blasting machine. Motor and blasting wheel are connected by belt. Much more blasting flow and higher power are available.

Motor power from 18.5kw to 75kw

Advantage

-Guard and seal: The guard plate of the blast turbines is lined with a chromium-containing alloy liner. The lining plates are lapped with each other in a labyrinth seal to prevent excessive abrasion and pellet leakage. The end guard plate and top guard plate of the blast turbines adopt arc-type multilayer labyrinth protection technology, and the top of the blast turbines has wear-resistant cast iron and the wear-resistant rubber double-layer sealing device ensures a tight seal and eliminates the phenomenon that the projectile penetrates the shell of the blast turbines, and the sealing effect is excellent.

-Low noise: The bottom of the blast turbines is equipped with damping rubber, and the top adopts a double-layer protection device of wear-resistant cast iron and wear-resistant rubber. The impeller of the shot blaster and the motor are directly connected, which effectively reduces the noise of the equipment. The noise less than 60dB. The blast turbines has the characteristics of high efficiency, low noise and low energy consumption.

-High-speed bearing: The bearing adopts Japanese NSK® or American BARDUN® (original imported), and the impeller and blast turbines can run at a high speed of 3000 rpm to ensure reliable performance of the blast turbine.

-The special guard plate structure increases the anti-wear life by 60%-200%.

-Maintenance costs are reduced by 60%.

-Blast media utilization increased by 15%.

-The impeller is made of imported 9SiCr alloy tool steel, and the main shaft and linkage plate are all made of 40CR material. The wear resistance and mechanical strength are greatly improved, which effectively guarantees the operation and long life of the blast turbines.

-In order to ensure the accuracy and balance of the required tolerances under the high-speed operation of the shot blasting machine, the main machining parts are all processed by CNC machining centers and CNC grinders.

-Blade assembly and disassembly quickly: Because the blade of this blast turbines is inserted from the center of the impeller, the blade is fixed by centrifugal force during the rotation of the impeller, so no clamping tools are needed. When disassembling the blades, 8 blades can be dismantled by tapping the outer end of the blades. It only takes 5 to 10 minutes and the wear of the blast turbine and the control cage, distributor can be checked at the same time. 

-The blades, distributor and control cage adopt the lost foam production process of GF+SPENCER in Switzerland, and are precision-casted with high chromium wear-resistant materials. The blade weight difference is controlled within 2+ grams, which greatly reduces The noise during the operation of the pelletizer prolongs the life of the vulnerable parts. The blade is generally more than 800-1000 hours, and the control cage, distributo and each guard are generally more than 3,500 hours.

-Using double disc impellers, compact disc dimensions, good dynamic and static balance performance, easy to ensure, and high shot blasting speed.

-Beautiful appearance, exquisite structure, convenient manufacturing and maintenance, and low noise.
