A crawler shot blasting machine, also known as a tumble belt shot blasting machine or rubber belt shot blasting machine, is designed for the efficient and uniform surface treatment of bulk quantities of small to medium-sized workpieces. This type of machine is particularly well-suited for removing rust, scale, sand, and burrs from various parts; preparing surfaces for painting, coating, or plating; and even shot peening to increase fatigue strength. It is commonly used in industries such as foundry, forging, automotive, and metal manufacturing.
Efficient Cleaning of Large Workpieces: They are ideal for blasting large, heavy, or oddly shaped parts that wouldn't fit well in traditional blasting cabinets. The continuous movement on the crawler track ensures all surfaces are exposed to the abrasive media for uniform cleaning.
Improved Productivity: The continuous processing nature of these machines allows for faster blasting of large workpieces compared to manual methods or using smaller blasting cabinets.
Reduced Labor Costs: Automating the blasting process with a crawler machine minimizes reliance on manual labor for handling heavy pieces, potentially lowering overall production costs.
Versatility: Some crawler shot blasting machines offer adjustable track speeds and blast intensity settings to accommodate a variety of workpiece sizes and cleaning requirements.
Continuous Blasting: Unlike blast cabinets where blasting stops for loading/unloading, crawler shot blasting machines offer a more continuous process. Workpieces are placed on a caterpillar track (hence the name "crawler") that moves them steadily through the blasting chamber. This allows for efficient processing of large or heavy pieces.
Multiple Blast Wheels: Strategically positioned blast wheels within the chamber bombard the workpieces with abrasive media as they travel on the crawler track. This ensures thorough cleaning of all surfaces, even on complex-shaped objects.
Durable Construction: These machines are built to handle the weight and potential impact of large workpieces. They typically feature robust construction materials and heavy-duty components for reliable operation in demanding environments.
