How roller conveyor shot blasting machine works ?

A Roller Conveyor Shot Blasting Machine is designed for surface treatment of flat or long workpieces, such as steel plates, profiles, pipes, or beams. It uses a roller conveyor system to transport workpieces through the blasting chamber, where abrasive media (such as steel shot or grit) is propelled at high speed onto their surfaces. Here’s a step-by-step explanation of how it works:

Working Principle

Loading:

Workpieces are placed onto the roller conveyor system at the entry point of the machine.

The rollers are motorized and can be adjusted to accommodate different workpiece sizes and weights.

Transportation:

The roller conveyor moves the workpieces into the blasting chamber at a controlled speed.

The speed can be adjusted based on the type of workpiece and the desired surface treatment.

Blasting:

Inside the blasting chamber, high-speed turbines (blast wheels) propel abrasive media (e.g., steel shot or grit) onto the surfaces of the workpieces.

The abrasive media removes rust, scale, paint, or other contaminants and prepares the surface for further processing.

Rotation:

The rollers rotate the workpieces as they move through the blasting chamber, ensuring that all surfaces (top, bottom, and sides) are evenly treated.

This rotation is crucial for achieving uniform surface treatment, especially for long or complex-shaped workpieces.

Abrasive Recovery:

After blasting, the abrasive media falls through a grid or conveyor system and is collected.

The abrasive media is then cleaned, separated from debris, and recycled back into the blast wheels for reuse.

Dust Collection:

A dust collector system removes dust and debris generated during the blasting process, ensuring a clean working environment and compliance with environmental regulations.

Unloading:

The workpieces exit the blasting chamber and are transported to the unloading area.

The treated workpieces are now ready for further processing, such as painting, coating, or assembly.

Key Components

Roller Conveyor System:

Motorized rollers transport workpieces through the machine.

Adjustable speed and rotation for different workpiece types.

Blasting Chamber:

(1) Enclosed area where the blasting process takes place.

(2) Equipped with blast wheels that propel abrasive media.

Abrasive Media:

Steel shot, grit, or other materials used for surface treatment.

Recovery System:

Collects, cleans, and recycles abrasive media for reuse.

Dust Collector:

Removes dust and debris to maintain a clean environment.

Control System:

Allows operators to adjust conveyor speed, blast intensity, and other parameters.
