China Professional Casting Machinery Supplier so many kinds of Shot Blasting Machine
Shot blasting machine is a kind of processing technology that uses a shot blasting machine to blast steel grit and steel balls onto the surface of a material object at high speed. Compared with other surface treatment technologies, it is faster and more effective, and can partially retain or punch the casting process.
Working Principle
Abrasive Acceleration: The shot blasting machine uses a centrifugal blast wheel or air-powered nozzles to accelerate abrasive particles (steel shot, grit, or ceramic beads) onto the workpiece surface.
Impact Effect: The high-speed impact of the shot removes scale, rust, oxides, or burrs while inducing compressive stresses to improve fatigue resistance (a process known as shot peening).
Recycling System: Abrasive media and debris are collected, separated via a cyclone or magnetic system, and recycled for repeated use.
Types of Shot Blasting Machines
It is divided into hook type shot blasting machine, roller table type shot blasting machine, suspension chain type shot blasting machine, mesh belt type shot blasting machine, crawler type shot blasting machine, turntable type shot blasting machine and other non-standard shot blasting machines according to different traveling modes.
Tumble Blast Machines: Used for small, bulk components (e.g., bolts, gears) that rotate in a barrel during blasting.Tumble type shot blasting machine is so popular machine in metal surface cleaning machines
Hanger-Type Machines: Parts are suspended on hooks or fixtures and blasted in a enclosed chamber.
Continuous Belt/Conveyor Systems: Ideal for mass production of flat or sheet metal parts.
Wheel Blasting vs. Air Blasting:
Wheel Blasting: Centrifugal force from rotating blades propels abrasives (energy-efficient for large-scale operations).
Air Blasting: Compressed air directs abrasives (precise control for delicate surfaces).
Key Components
Blast Wheel: Core component for accelerating abrasives (made of wear-resistant materials like chromium alloy).
Blasting Chamber: Reinforced enclosure to contain abrasives and protect operators.
Dust Collector: Removes particulate matter to meet environmental regulations.
Abrasive Recovery System: Separates reusable media from waste using screens, air wash, or magnetic separators.
Control Panel: Automated systems adjust parameters like blast time, wheel speed, and abrasive flow.
Applications
Surface Preparation: Cleaning castings, weldments, or forgings before coating or painting.
Deburring: Removing sharp edges from machined parts.
Shot Peening: Enhancing fatigue life of components like springs, gears, and turbine blades.
Decorative Finishing: Creating uniform textures on architectural metals.
