Equipment description and main structure of shot blasting line
I. Overview of the equipment
function : Remove the oxide skin, rust and burr on the surface of the workpiece by throwing metal abrasive at high speed, improve the adhesion and surface roughness of the coating.
Application field : steel structure, auto parts, casting parts, file cabinets and other metal workpiece surface treatment.
Standard process : feeding → shot blasting → abrasive separation → dust removal → workpiece blanking
Safety and environmental protection
Emergency brake : cut off power in 0.5 seconds
Automatic abrasive replenishment system : reduces manual intervention
heat recovery module (optional) : using shot blasting friction heat to preheat the workpiece, saving 20% of energy
I. Core structure and components
Shot blast Assembly
composition : impeller, shot parting wheel, directional sleeve, wear-resistant protection plate (high chromium alloy material)
Performance : Ejection speed: 70-90m/s (adjustable)
Single power: 11-30kW
technology upgrade : By 2025, mainstream models will be equipped with intelligent frequency conversion control, reducing energy consumption by 15%
