Small-Sized Roller Conveyor Shot Blasting Machine

1. Brief Profile

The Small-Sized Roller Conveyor Shot Blasting Machine is a compact, automated surface treatment system designed for medium-to-high-volume industrial applications requiring efficient cleaning, descaling, and surface strengthening of metal workpieces. Utilizing high-velocity steel shots or abrasives, it removes rust, mill scale, and welding residues while improving coating adhesion and fatigue resistance.

This machine is engineered for versatility, accommodating a wide range of workpiece sizes and shapes, including small steel plates, pipes, automotive components, and structural profiles. Its space-saving design and modular construction make it ideal for workshops, foundries, and SMEs (Small and Medium-Sized Enterprises) with limited floor space. Certified to international standards (CE, ISO9001), it combines reliability with cost-effectiveness, offering a scalable solution for industries such as automotive, construction, and machinery manufacturing.

2. Application

The Small-Sized Roller Conveyor Shot Blasting Machine is widely adopted in sectors requiring precise surface preparation for enhanced durability and coating performance. Key applications include:
