A roller conveyor blast machine is a type of industrial equipment used for cleaning, descaling, or surface preparation of workpieces in various industries such as manufacturing, automotive, foundry, and metal fabrication. It is specifically designed to handle large and heavy workpieces that can be transported on a roller conveyor system.

The machine typically consists of a chamber or blast cabinet where the cleaning process takes place, and a roller conveyor system that moves the workpieces through the chamber. The roller conveyor is made up of a series of rotating metal rollers that support and transport the workpieces.

Inside the blast chamber, there are blast wheels or turbines strategically positioned to direct high-speed abrasive media (such as steel shot, grit, or other abrasive materials) onto the surface of the workpieces. The blast wheels rotate at high speeds, propelling the abrasive media towards the workpieces, effectively removing contaminants, rust, scale, paint, or other coatings from the surfaces.

The roller conveyor blast machine can be equipped with various features and configurations depending on the specific application requirements. These features may include variable speed control of the roller conveyor, adjustable blast wheel positioning, multiple blast zones or chambers for different cleaning stages, dust collection systems to remove the generated dust and debris, and automated systems for loading and unloading workpieces.

The advantages of using a roller conveyor blast machine include high productivity, consistent and uniform cleaning results, the ability to handle heavy and large workpieces, and efficient use of abrasive media. It is commonly used for cleaning or preparing surfaces before further processing, such as painting, coating, or inspection.

It is important to note that specific operating procedures, safety precautions, and maintenance guidelines should be followed when using a roller conveyor blast machine to ensure safe and optimal operation. Manufacturers or equipment suppliers typically provide detailed instructions and guidelines for proper usage and maintenance.
