What is a Wet Blasting Machine?

A wet blasting machine is a surface treatment system in which abrasive material (such as sand, aluminum oxide, or glass beads) is mixed with water and sprayed onto a surface at high pressure. Unlike traditional dry blasting, the addition of water significantly reduces dust emissions and makes the process more environmentally friendly.

Working Principle

1. Mixing Water and Abrasive: Abrasive material is mixed with water and held in a tank.

2. Pressurized Spraying: This mixture is sprayed onto the surface through a nozzle using compressed air or a hydraulic system.

3. Surface Cleaning: The sprayed mixture removes rust, paint, grease, and other coatings from the surface.

4. Waste Control: Water suppresses airborne dust and makes waste collection easier.

Advantages

✅ Reduced Dust Emission: Produces up to 90% less dust compared to traditional dry blasting.
✅ Minimized Thermal Stress: Water prevents excessive heating of the surface, reducing the risk of material deformation.
✅ Eco-Friendly: Lower dust emissions make the process safer for both workers and the environment.
✅ Gentle Surface Cleaning: The cushioning effect of water enables more controlled cleaning on delicate surfaces.
✅ Abrasive Efficiency: Abrasive material is used more efficiently when mixed with water.

Applications

• Automotive Industry: Cleaning rust, grease, dirt, and paint from vehicle bodies and parts

• Marine Industry: Removal of algae, rust, grease, and corrosion from ship hulls and components

• Aerospace: Maintenance and surface preparation of aircraft components

• Metal Fabrication: Post-welding surface cleaning, roughening, and pre-paint surface preparation

Optional Features

• Body: Long-lasting AISI 316 stainless steel body, resistant to abrasion

• Rinse System: Filters and reuses water from the main tank for rinsing

• Separator: Allows abrasive recovery without draining the tank, thanks to the built-in grit separator

• Timer Relay: Allows wipers to continue operating briefly after blasting stops or pauses
