In the field of modern industrial surface treatment, industrial shot blasting machines are core equipment for achieving rust removal, oxide scale removal, surface strengthening, and roughness optimization of metals. They are widely used in industries such as steel structures, casting, automobiles, shipbuilding, and construction machinery. Compared to traditional pickling, sandblasting, and manual grinding processes, industrial shot blasting machines, with their core advantages of high efficiency, environmental friendliness, low cost, and stable processing quality, have become indispensable key equipment in industrial production.

Definition and Composition of Industrial Shot Blasting Machines
An industrial shot blasting machine is an industrial surface treatment device that utilizes the centrifugal force generated by a high-speed rotating impeller to propel abrasive materials such as steel shot, stainless steel shot, and casting shot at a high speed of 70-100 m/s onto the workpiece surface. Through impact and scraping, it completes rust removal, oxide scale removal, welding slag removal, surface strengthening, and roughness adjustment. It is also commonly referred to in the industry as a sandblasting machine or cleaning machine. Its core function differs from chemical treatment processes; it operates entirely through physical processes, without acid or alkali pollution, and can improve the fatigue strength of metal surfaces by more than 30%, extending the service life of workpieces.
The core structure of an industrial shot blasting machine consists of five main modules: a shot blasting system (blasting heads), a shot recycling and separation system, a dust removal system, a control system, and a conveying system. These modules work together to achieve a fully automated process from workpiece feeding, shot blasting, shot recovery, dust purification, to discharge.
Common Types of Industrial Shot Blasting Machines
1. Hook-type Shot Blasting Machine
- Structure: Workpieces are suspended by single/double hooks and transported to a sealed shot blasting chamber via a track. The hooks can rotate 360°, and multiple blasting heads project shots at multiple angles.
- Suitable for: Large, heavy, and complex workpieces (automobile chassis, bridge components, large castings, steel structural components).
- Features: 360° cleaning without dead angles, no damage to workpieces, high load-bearing capacity (up to 5 tons); suitable for single-piece/small-batch processing of heavy workpieces.
2. Through-type Shot Blasting Machine (Roller Conveyor Type)
- Structure: Workpieces are continuously transported via a roller conveyor. Blasting heads are arranged on the top, bottom, and sides of the shot blasting chamber, and the workpiece passes through the shot blasting area in a straight line.
- Suitable for: Long, strip-shaped, and plate-shaped workpieces (steel plates, H-beams, angle steel, steel pipes, profiles), for large-scale continuous production.
- Features: Extremely high efficiency (processing capacity 100-500㎡/h), automated production lines, suitable for large-scale production lines; the mainstream equipment in steel structure plants.
Core Highlights of YG Industrial Shot Blasting Machines
YG Industrial Shot Blasting Machines has focused on the R&D and manufacturing of surface treatment equipment for 18 years, deeply cultivating the global market. Relying on mature technology and stringent processes, its products are exported to more than 100 countries, becoming a benchmark brand in the industrial shot blasting machine field. Compared with similar products in the industry, YG shot blasting machines have five core advantages:
1. Intelligent PLC Precise Control, Controllable Processing Quality
Equipped with a Siemens PLC intelligent control system, it can precisely adjust the blasting speed, shot flow rate, and conveying speed, supporting one-click switching of process parameters; equipped with a touch screen operating interface, it monitors the equipment operating status in real time (current, temperature, shot quantity), automatically alarms for abnormalities, lowers the operating threshold, and allows novices to quickly get started.
2. High Wear-Resistant Configuration, Doubled Service Life
Key components (blasting head blades, directional sleeves, shot distribution wheels) are made of high-chromium alloy wear-resistant material, offering high hardness and impact resistance, resulting in a service life 2-3 times longer than ordinary materials. The shot blasting chamber walls are lined with Mn steel plates to prevent damage from shot impacts, extending the overall machine service life to over 10 years and reducing the frequency of replacement of vulnerable parts.
3. High-Efficiency Shot Circulation System, Reduced Consumable Costs
Utilizing a dual separation technology of air separation and magnetic separation, the shot recovery rate is ≥98.5%, ensuring thorough separation of broken shot and dust, preventing broken shot from scratching workpieces. An automatic shot replenishment device monitors the shot quantity in real time and automatically replenishes it, eliminating the need for frequent manual replenishment and saving up to 30% on consumable costs over long-term use.
4. Pulse Dust Removal System, Environmentally Compliant
Standard configuration includes an eight-core automatic back-flushing pulse dust collector, achieving a dust purification rate ≥99.5% and an emission concentration ≤30mg/m³, complying with EU CE and domestic environmental standards. The sealed chamber design prevents dust leakage, improving the workshop’s working environment and eliminating concerns about environmental inspections.
Frequently Asked Questions about Industrial Shot Blasting Machines
1. Q: What is the difference between an industrial shot blasting machine and a sandblasting machine?
A: The core difference lies in the power source and efficiency. Shot blasting machines use centrifugal force to propel steel shot, resulting in high efficiency (3-5 times that of sandblasting), uniform processing, and recyclable steel shot. Sandblasting machines use compressed air to spray abrasive, resulting in low efficiency, high abrasive loss, and more dust; they are suitable for small areas and precision parts.
2. Q: Do workpieces treated by shot blasting need to be painted again?
A: Yes. Shot blasting only removes rust, scale, and roughness, improving coating adhesion; after treatment, painting should be done promptly (ideally within 4 hours) to prevent secondary rusting.
3. Q: How often should the steel shot be replaced?
A: The lifespan of steel shot depends on the material and hardness of the workpiece being treated, generally requiring replacement every 1-3 months; daily use requires filtering broken shot through a separation system and replenishing with new steel shot to maintain uniform shot size.
4. Q: Does a shot blasting machine require a foundation?
A: Fixed shot blasting machines (hook-type, through-type) require a concrete foundation (thickness ≥ 20cm) to ensure stable operation; mobile road-mounted shot blasting machines do not require a foundation and can be used on a level surface.
5. Q: Can YG shot blasting machines be customized?
A: Yes. YG supports non-standard customization. We can customize the number of blasting heads, equipment size, conveying method, automation configuration, etc., according to the workpiece size, weight, and production capacity requirements to meet the personalized production needs of our customers.
