A hanger shot blasting machine, also known as a hook-type shot blasting machine or simply a suspended shot blasting machine in the industry, is an automated surface treatment device that uses hooks to suspend workpieces and achieve 360° shot blasting cleaning without dead angles. Its core function is to remove oxide scale, rust, and burrs from the workpiece surface, while simultaneously strengthening the surface to prepare for subsequent coating, electroplating, and other processes. It is widely applicable to large and medium-sized workpieces and irregularly shaped parts that cannot be tumbled, and differs from the general-purpose industrial shot blasting machine in that it focuses more on precise cleaning. YG’s hanger shot blasting machine mainly consists of a shot blasting chamber, a shot blaster assembly, a hook conveying system, a shot circulation system (including a hoist, separator, and storage hopper), a dust removal system, and an electrical control system. The workpiece is suspended on a specially designed hook by an electric hoist or chain and enters the shot blasting chamber. The shot blaster rotates at high speed, throwing steel shot (or stainless steel shot, aluminium shot, etc.) at extremely high speeds onto the workpiece surface, thoroughly and completely impacting it. After cleaning, the shot and impurities are separated through a shot circulation system. The reusable shot is returned to the shot blaster, while dust is collected by a dust collection system.

We not only offer standard hook-type shot blasting machines, but also sandblasting booths, industrial shot blasting machines, small sandblasting machines, dry ice cleaning machines, and more, providing a one-stop solution for the surface treatment challenges of small and medium-sized enterprises, helping them reduce costs, increase efficiency, and improve product quality.

7 Features of the YG Hanger Shot Blasting Machine
- 360° thorough cleaning with high surface uniformity: The hook rotates automatically (adjustable speed 0-10 rpm), working in conjunction with multiple shot blasters to ensure even impact of shot on all surfaces of the workpiece. The resulting surface roughness meets standards, with no omissions or scratches, surpassing the cleaning effect of ordinary industrial shot blasting machines.
- High efficiency and energy saving, improving production efficiency: Utilising high-power energy-saving shot blasters (7.5-22kW), the cleaning efficiency can reach 1-5 tons/hour, 8-10 times that of manual cleaning. A large number of workpieces can be cleaned daily, significantly shortening the production cycle and meeting the batch production needs of small and medium-sized enterprises. Some models can be upgraded to a spinner hanger shot blasting machine for even higher rotational efficiency.
- Automatic shot circulation, reducing waste: Equipped with a complete shot recovery, screening, and conveying system, the shot recovery rate reaches over 98%, eliminating the need for frequent shot replenishment and reducing consumable costs. The screening system filters impurities, ensuring a clean shot and preventing scratches on the workpiece surface.
- Safe and environmentally friendly, meeting workshop standards: The enclosed enclosure design and pulse dust removal system ensure dust emission concentration ≤30mg/m³, meeting industrial environmental standards. The equipment is equipped with emergency stop, overload protection, and safety door interlocks to prevent shot blasting and equipment malfunctions, ensuring operator safety.
- Easy to operate, no specialised team required: Utilising a PLC touchscreen control system, it features one-button start/stop. Parameters (shot blasting time, hook speed, shot flow rate) are flexibly adjustable. Ordinary workers can operate the equipment after one day of training, reducing labour and training costs.
- Versatile and adaptable to various workpieces: It can accommodate large and medium-sized workpieces and irregularly shaped parts weighing 100-2000kg, such as castings, forgings, automotive parts, and engineering machinery structural components, without requiring replacement of core components. It can also be used with sand blasting rooms and small sandblasting machines to meet different application needs.
- Durable structure and low failure rate: Key components are made of highly wear-resistant materials; the overall failure rate of the equipment is less than 2%, it can operate continuously for 24 hours, reduce downtime for maintenance, ensure production continuity, and the maintenance cost is far lower than that of similar products.
