Roller Conveyor Shot Blasting Machine | Universal Q69 Series
The Roller Conveyor Shot Blasting Machine is the definitive universal solution for the continuous, automated surface treatment of steel plates and standard structural profiles. As the workhorse of the Q69 series, it is engineered to provide a balanced cleaning performance across a wide range of flat and semi-structural materials, making it the ideal choice for general steel fabrication and shipbuilding.
This system delivers a consistent Sa 2.5 surface finish while maintaining maximum throughput, offering a highly flexible platform for workshops that handle diverse material types daily.
Product Introduction
Our Roller Conveyor Shot Blasting Machine (Q69 Series) represents the peak of versatility in automated descaling. While specialized models like the QH69 are optimized for high-aspect-ratio workpieces such as H-beams, the standard Q69 series is designed as an all-around powerhouse. It excels at cleaning a mix of steel plates, angles, channels, and simple weldments in one continuous, non-stop process.
Powered by high-efficiency direct-drive turbines and ABB electrical components, the machine ensures uniform abrasive coverage across the entire effective width. Controlled by a Siemens PLC system, it integrates seamlessly into your factory logistics, providing a robust, ISO 8501-1 compliant finish for any general-purpose industrial application.

Q69 Roller Conveyor Shot Blasting Machine: FAQ'S
Is the Q69 suitable for H-beams or workpieces with high aspect ratios?
The standard Roller Conveyor Shot Blasting Machine (Q69) is a general-purpose unit ideal for plates and a variety of profiles. For workpieces with high aspect ratios, such as H-beams or tall structural frames, we recommend our QH69 series, which features specialized blast wheel angles designed to penetrate the deep webs and flanges of vertical structures.
Can I use this machine for very thin steel plates?
Yes. The precision-aligned roller system ensures that even relatively thin plates move smoothly through the chamber without warping. For ultra-thin material, the conveyor speed and blasting intensity can be adjusted via the VFD control.
What is the difference between this and a Steel Plate Pretreatment Line?
This is a standalone shot blasting module. A Pretreatment Line is a more complex system that includes automated pre-heating, blasting, painting, and drying. This Q69 machine can, however, serve as the core cleaning unit within such a line.
How do I maintain the Sa 2.5 cleanliness standard?
By utilizing the automated abrasive replenishment system and keeping the Siemens PLC settings optimized for the specific rust grade of your material, the machine consistently achieves the Sa 2.5 finish required for high-quality coating and welding.
