Home / Airless Shot Blasting Machine / Airless Diabola Conveyor Shot Blasting Machine Manufacturer
Diabola conveyor system rotates pipes and round jobs during blasting for complete outer surface cleaning. Continuous handling improves productivity and ensures even blasting results.
The Airless Shot Blasting Machine - Diabola Conveyor Type is a continuous, high-production system designed for cleaning pipes, round sections, cylindrical jobs, and long components that need rotational blasting. The parts pass through the blast chamber on the conveyor while several blast wheel units clean the whole outer surface evenly in a single pass, with no manual turning required.
What sets this type apart is the diabola rollers, angled V-shaped rollers that rotate the round job and move it forward at once. As the part turns, the abrasive reaches its full circumference for an even finish along the length. It suits fast, automated pipe handling.
Available Configurations
For Round, cylindrical, and spherical parts
Smart Process Overview
Components are loaded onto the inlet conveyor and moved into the blasting chamber. Inside the tunnel, the angled diabola rollers rotate the job while moving it forward, so it turns steadily past the blast wheels.
For pipes and round jobs, the diabola rollers keep the component turning as it moves, so the full outer surface stays exposed to the abrasive stream. This gives uniform cleaning, rust removal, and scale removal all the way around the circumference.
Used abrasive falls into the hopper and is recovered through screw conveyors, a bucket elevator, and an air wash separator for reuse. Dust and fine particles are extracted through the integrated dust collector system. Cleaned components exit through the outlet vestibule ready for coating or further processing.

Engineered Output Parameters
Custom Engineered Mechanism
The Diabolo Type configuration uses specially inclined rollers to support and rotate pipes or round jobs automatically during blasting. The roller angle sets how fast the part travels and how many turns it makes, so the finish is matched precisely to the job.
This steady rotation lets the abrasive reach every part of the outer surface while the component moves through the machine. It is ideal for pipes, cylinders, and round sections needing full circumferential cleaning in continuous flow.
The Airless Shot Blasting Machine – Diabola Conveyor Type is ideal for continuous mass production of pipes and cylindrical jobs requiring complete rotational blasting. It offers high efficiency, repeatable blasting quality, and smooth conveyorized handling.
Its synchronized roller movement and easy integration with coating lines make it a practical choice for modern pipe processing facilities.
