Home / Airless Shot Blasting Machines / Blast Wheel Shot Blasting Turbine
Precision-engineered blast wheel designed to accelerate abrasive media for maximum cleaning efficiency. Durable construction, balanced rotation, and optimized throwing pattern ensure reliable blasting performance.
The Blast Wheel (Shot Blasting Turbine) is the core working component of every airless shot blasting machine. It converts electrical energy into kinetic energy to accelerate abrasive media such as steel shot, steel grit, garnet, or cut wire shots, projecting them onto the workpiece surface at high velocity.
Designed for high efficiency, durability, and uniform abrasive distribution, the blast wheel is responsible for achieving effective cleaning, peening, deburring, and surface roughening. A properly engineered shot blasting turbine ensures maximum blasting performance with minimum abrasive consumption, making it one of the most critical parts of any industrial shot blasting system.
We design and supply optimized blast wheel systems with precise positioning and abrasive selection to achieve maximum productivity and uniform surface finish.
Smart Process Overview
Abrasive media enters the control cage through the feed spout and is guided toward the impeller. The impeller provides the initial acceleration and directs the abrasive toward the rotating blades. The blades then accelerate the abrasive to high velocity before it exits the wheel in a controlled blast pattern.
When the abrasive strikes the component surface, it removes rust, mill scale, old coatings, burrs, or contaminants, depending on the application. Accurate control of throwing direction and wheel speed ensures efficient surface preparation with consistent cleaning quality.
Optimized Wheel Variants
The motor is directly coupled with the rotor, resulting in higher efficiency with no transmission loss. This design offers compact construction and lower maintenance requirements.
Uses a pulley and V-belt arrangement between the motor and rotor. It provides flexible mounting options and easier servicing.
Advanced blade geometry improves abrasive acceleration and blasting efficiency while reducing abrasive consumption.
Blade design allows both sides to be used, extending blade life and reducing downtime for replacement.
