2. What is Shot Blasting?
High-Velocity Surface Treatment
Shot blasting harnesses high-velocity abrasive pellets—steel
shots, grits, and other media—to meticulously clean and prepare
metal surfaces for industrial applications.
This powerful process efficiently removes rust, scale, paint, and
other stubborn impurities without relying on harsh chemicals,
making it an environmentally conscious choice.
Widely preferred across industries for surface preparationdue to
its exceptional speed, environmental safety credentials, and
long-lasting durability.

3. Core Mechanism: Centrifugal Wheel
Propulsion
01Motor Activation
High-power motor spins the
centrifugal wheel (blast wheel) at
tremendous speeds within a fully
enclosed chamber
02Media Feeding
Abrasive media flows from the hopper
into the rotating wheel, creating a
controlled feeding system
03
Kinetic Propulsion
Centrifugal force propels media at target surfaces with precise kinetic energy,
achieving optimal cleaning and surface roughening for superior coating
adhesion

4. Shot Blasting Process Flow
Loading Stage
Components are carefully positioned on conveyor systems or tables within the blast chamber, ensuring optimal exposure
angles
Abrasive Propulsion
Centrifugal wheels accelerate steel shotsand grit particles towards components with controlled velocity and precision
Surface Impact
High-energy abrasive particles strike surfaces, effectively removing contaminants whilst creating ideal surface texture
profiles
Recovery & Collection
Advanced systems collect and recycle used media whilst capturing dust particles, maintaining a pristine working environment
