Manufacturers struggle with slow, inefficient surface treatment processes, leading to delays, high labor costs, and inconsistent product quality. Finding a solution that increases productivity while maintaining surface standards is crucial.
A roller conveyor shot blasting machine streamlined operations for a manufacturing company, resulting in a 30% increase in production efficiency by reducing cleaning times, improving consistency, and lowering operational costs.
This case study explores how implementing a roller conveyor shot blasting machine transformed an industrial production line.
Understanding Roller Conveyor Shot Blasting Machines
Manufacturing industries require efficient surface cleaning to remove rust, scale, and coatings before painting or welding. Traditional methods, such as manual grinding, are labor-intensive and inconsistent.
A roller conveyor shot blasting machine automates the surface treatment process by using high-speed steel shots to clean and prepare metal surfaces efficiently.
How Does It Work?
- Loading – Workpieces are placed onto the conveyor belt.
- Blasting Chamber – Multiple blast wheels propel abrasive media at high velocity, removing impurities.
- Abrasive Recovery – Used media is collected, cleaned, and reused.
- Dust Collection – A filtration system removes dust and contaminants.
- Finished Surface – Cleaned metal emerges ready for coating or further processing.
