An Over-Head Conveyor Multi Nozzle Blasting Machine is a type of industrial surface-treatment equipment used primarily for automated cleaning, preparation, and finishing of parts in a production line. It combines an overhead conveyor system that carries parts through a blasting chamber with multiple blasting nozzles working simultaneously to deliver high throughput and uniform surface treatment. This machine is continuously sandblasting with a large number of nozzles. Nozzles placed with special calculations and they make sandblasting by providing granules to reach every point of the material to be blasted.

????️ Key Features

✔ High Productivity

• Continuous operation on an overhead conveyor suits large volumes or mass production. Multiple nozzles treat large areas faster than single-nozzle setups. 

✔ Uniform Surface Treatment

• Multi-nozzle design allows better coverage and repeatable results, reducing the need for manual correction. 

✔ Adjustable Parameters

• Conveyor speed, air pressure, and nozzle orientation are usually adjustable, allowing the system to be tuned for different parts and finish requirements. 

✔ Integrated Dust Control

• Many systems include dust extraction and closed-loop systems to keep the workspace safe and compliant with environmental or workplace safety standards. 

✔ Durable Construction

• Built from wear-resistant materials to withstand abrasive media and heavy industrial use. 

???? Typical Applications

These machines are widely applied in industries where surface preparation is critical before further processing (e.g., painting, coating, bonding) or where contaminants must be removed:

• Automotive and aerospace parts: cleaning castings, bodies, welds

• Metal fabrication: removal of rust, scale, old coatings

• Foundries and machining: desanding, degreasing, surface profiling

• Pre-coating preparation: improving adhesion for paint or coatings

• General cleaning and finishing for metal, stone, concrete, or wood components depending on nozzle and media type.
