Steel belt shot blasting machine
- 产品详情
Qingdao Qingdao KEEJOO Group’s steel belt shot blasting machine incorporates multiple patented technologies, featuring a proprietary direct-drive high-efficiency blasting system, a modular abrasive separation unit, and a maintenance free lifting system. Designed for the continuous processing of various small-to-medium-sized workpieces in batches, it is widely used in industries such as casting, forging, hardware, automotive parts, and construction machinery. Renowned for
its stable performance, exceptionally low failure rate, and long service life, it is a preferred choice for batch cleaning operations and stands as one of Qingdao KEEJOO Group’s flagship export models.
Adaptation Scenarios
Qingdao KEEJOO Group’s steel belt shot blasting machine is specifically designed for the comprehensive surface treatment of batches of small-to-medium-sized workpieces that are resistant to impact. Applicable industries and workpieces include the following:
Automotive Parts and Hardware Industry: Rust and oxide scale removal for fasteners, bolts and nuts, springs, gears, stamped parts, and precision hardware components.
Casting and Forging Industry: Removal of adhering sand and scale from small cast steel, cast iron, and forged parts; strengthening of workpiece surface hardness.
Machining industry: Deburring small machined parts, removing machining marks, and achieving a uniform matte surface finish.
Hardware Industry: Surface finishing of metal components, stress relief, and enhancement of coating adhesion; suitable for subsequent painting and electroplating processes.
Unlike standard steel belt shot blasting machines on the market, KEEJOO brand’s steel belt shot blasting machine features comprehensively optimized core components and systems, balancing efficiency, durability, and energy conservation:
1. Highly efficient automation, significantly reducing labor costs.
The steel belt conveyor system enables continuous batch processing; mid-sized units can process 500–800 kg of workpieces per hour, delivering cleaning efficiency 3–5 times higher than manual sandblasting and far surpassing manual grinding or chemical pickling. Supporting automatic loading and unloading—including automatic discharge via crawler reversal—the system can operate as a standalone unit or integrate into automated production lines, significantly reducing the need for manual intervention.
2. Uniform cleaning with no dead zones, combined with a workpiece strengthening effect.
The multi-angle shot blasting design, combined with the tumbling action of the workpiece conveyor belt, ensures coverage of hard-to-reach areas—such as grooves and crevices—that are difficult to treat with conventional methods. This approach delivers superior cleaning consistency compared to traditional drum-type equipment, achieving cleanliness levels that meet the international SA3 standard. Furthermore, the high-frequency impact of the steel shot generates uniform compressive stress on the metal surface, relieving 80% of processing-induced stress and enhancing fatigue resistance and wear resistance; this integrates cleaning and strengthening processes, extending the workpiece's service life by three to eight times.
3. Environmentally compliant, lower energy consumption
It utilizes an enclosed structure integrated with a dust collection system, achieving a dust recovery rate of ≥99% and keeping dust emission concentrations below national environmental standards, thereby avoiding the dust pollution and waste liquid disposal challenges associated with traditional processes. Energy consumption is reduced by approximately 30% compared to conventional sandblasting methods, and select models feature heat recovery units for even greater energy efficiency.
4. Easy to maintain, low operating costs
The modular design facilitates the replacement of wear parts, and the steel belt offer a service life exceeding 3,000 hours; select models feature intelligent fault diagnosis, helping to reduce annual downtime by 80%. The abrasive media is recyclable, resulting in low consumable usage and reduced processing costs per unit. Operators including novices can run the equipment after minimal training, thereby lowering labor entry barriers and training expenses.
5. Highly adaptable with a wide range of compatibility.
By adjusting shot blasting parameters, the system accommodates various materials—such as cast iron, aluminum alloy, and stainless steel—as well as workpieces of diverse shapes, including complex profiles and small components. It is particularly well-suited for the batch cleaning of small-to-medium-sized castings, forgings, stamped parts, and automotive components, and is capable of processing hot workpieces with a high degree of operational flexibility.
