Wet blast cabinet YG series

automaticfor heavy-duty applications

Overview
A sand blasting machine (blast tank) uses a high-speed abrasive stream propelled by compressed air to clean, derust and prepare metal or non-metal surfaces for coating. It removes rust, scale and old paint while creating a controlled surface profile for improved coating adhesion.

Main types

• Dry Sand Blasting Machine: Operates with dry abrasive only. Simpler design and lower initial cost; suitable for heavy-duty outdoor cleaning where flash rust risk is manageable.
• Wet Sand Blasting Machine: Mixes water with abrasive media (approx. 1:1). Greatly reduces airborne dust and helps meet stricter environmental or indoor-site requirements.

Capacity & Mobility

• Portable Sand Blasting Machine: Typical diameters 400–700 mm. Units are wheeled, hold ~100–400 kg of abrasive and usually weigh under 300 kg for easier site movement.
• Stationary Sand Blasting Machine: Larger tanks (800–1200 mm) mounted on structural legs; hold up to ~800 kg abrasive. Higher capacity reduces refill frequency but does not increase instantaneous blasting rate.

Air supply & recommended accessories
A blast tank requires a dedicated air compressor. Example: a 600-type unit typically needs 4–6 m³/min at 0.8 MPa. Industrial setups use stationary compressors with air receivers; field projects often use mobile diesel compressors. For tanks under 700 mm diameter, pair with a 25 mm ID hose and an 8 mm or 10 mm nozzle. Pneumatic control valves or automatic control enable remote gun switching and reduce labor requirements.

Common abrasive media & consumption

• Typical abrasives: brown corundum, dustless garnet, copper slag, silica sand.
• Example consumption: 40–50 mesh abrasives ~100 kg per 10 minutes (varies with nozzle, pressure and operator technique).
• Abrasive grains can be reused/recycled until they degrade into fine dust.

Case study (example)

• Background: Contractor required rust removal and repainting of a structural river bridge.
• Challenge: Manual methods were slow and scaffold movement limited heavy equipment.
• Solution: Selected a YG Machinery 600-type mobile dry unit with a 6 m³/min diesel compressor and a Q235B steel tank (6 mm wall).
• Results: Cleaning speed ~25 m²/h, labor reduced ~60%, and paint adhesion pass rate improved to ~98%.

FAQ (selected)

• What drives the sand blasting machine price? Factors include steel plate thickness (e.g., 8 mm carbon steel), pneumatic control options and whether an air compressor or automation is included.
• Which abrasive media should I use and can it be recycled? Common choices are brown corundum, garnet, copper slag and silica sand. Abrasives are reusable until they break down; selection depends on the surface, finish required and local regulations.
