Model of High-Pressure Sand Blasting Machine
1. Brief Profile
The High-Pressure Sand Blasting Machine is a specialized industrial system designed for aggressive surface preparation, cleaning, and finishing tasks. Utilizing compressed air at pressures up to 150 PSI (10.3 bar), this machine propels abrasive media (e.g., steel grit, aluminum oxide, silica sand) at high velocity through a nozzle to remove contaminants, rust, paint, or imperfections from substrates. Engineered with heavy-duty steel or stainless-steel construction, it is built to withstand rigorous industrial environments, including shipyards, automotive workshops, and construction sites.
Key features include automatic pressure regulation, abrasive recycling systems, and dust collection modules, ensuring efficiency and compliance with environmental and safety standards such as OSHA, ASME, and CE. The machine’s modular design allows customization for specific applications, from portable units for on-site work to stationary cabinets for controlled environments.
This model is favored for its high productivity, precision, and ability to handle tough materials, making it indispensable in industries requiring durable surface treatments.
