Turntable Shot Blasting Machine

Working Principle and Process Flow

Workpieces are placed on the indoor turntable. The variable-frequency drive system ensures smooth rotation at 0.3-3 rpm. Shot is projected at high speed through top and side blast wheels to achieve multi-angle coverage. The removed scale and shot are recovered by the bottom scraper, conveyed by screw conveyor to the bucket elevator, separated by air-wash separator, and then recycled. Dust is filtered by the pulse cartridge dust collection system before compliant discharge. When the workpiece rotates out of the chamber with the turntable, quality inspection can be performed directly.

Process flow: loading -> turntable rotation -> shot blasting -> rotate out for inspection -> unloading

Product Advantages

Zero tumbling and low damage: The workpiece rotates smoothly with the turntable without dropping or collision, making it especially suitable for thin-walled, precision, and high-value parts.

Visible process connection: Once the workpiece rotates out of the chamber, the cleaning result can be observed directly, supporting in-line quality inspection and reducing waiting time for the next process.

Flexible blasting layout: Blast wheels can be arranged from top and side angles to match complex geometries and ensure full coverage.

High automation and digitalization: PLC + touch-screen control allows programmable storage of process parameters. Industry 4.0 data interfaces are reserved for remote monitoring and MES integration.

Low total cost of ownership (TCO): Shot recovery rate is >=95%. The wear-resistant manganese-steel chamber and quick-connect liners reduce energy consumption by 10%-15% under equivalent cleaning results, and wear-part service life is above the industry average.

International environmental compliance: The fully enclosed chamber plus pulse cartridge dust collection keeps dust emission <=30 mg/m3 and meets ISO 14001 and mainstream European and American environmental regulations.

Ready to install and use: The compact structure requires no foundation pit, shortens installation time, and reduces floor space.
