Product Overview
The Continuous Catenary Shot Blasting Machine utilizes a continuous, indexing, or advanced power-and-free pusher-type overhead conveyor system to transport workpieces. This design allows workpieces to remain stationary during loading/unloading and within the blasting zone, enabling precise, fixed-point processing. Depending on the specific workpiece, the system supports single-point loads ranging from 50 kg to 2,000 kg. Offering high productivity and reli

Introduction to the Components of the Shot Blasting Machine
The blast wheel and motor adopt Germany-joint developed high-efficiency HP technology. Compared with conventional old-style blast wheels, this design eliminates multiple friction loss links, lifting motor efficiency by 20%, cutting down fault points and slashing maintenance costs by 50%.
It features a more compact footprint than traditional blast wheels, supports arbitrary installation angle arrangement, and enables far easier inspection and maintenance.
Constant blasting performance is maintained throughout operation, free from inconsistent and fluctuating cleaning quality seen on conventional units.
Blades and all wear-resistant consumables are manufactured in Taiwan via high-chromium investment precision casting, delivering outstanding abrasion resistance. Their service life ranges from 1,200 to 4,000 hours, 3–4 times longer than ordinary casting materials.
Blast wheel impeller: Treated with carburizing wear-resistant alloy. The impeller hub is one-time finished by high-precision CNC machining centers for ultra-high dimensional accuracy, ensuring perfect dynamic balance during high-speed rotation, low vibration, low noise and extended service life.
Equipped with SKF bearings imported from Sweden.
Fitted with genuine Siemens motors.
German Schenck dynamic balancing tester is applied to guarantee precise high-speed dynamic balance of impeller hubs.
2 1 Abrasive flow valve
1. Semi-automatic flow control system for regulating the flow of abrasive media into the blast wheel, featuring manual adjustment of the steel shot flow rate.
2. Fully sealed structural design, featuring a lockable inspection opening and equipped with two bearings.
3. A manual shut-off valve is installed above each flow valve; this can be closed to stop the flow of media from the hopper, thereby facilitating maintenance of the flow valve.
3Blasting chamber
1. The shot blasting chamber is constructed from welded manganese steel.
2. Manganese steel protective plates are installed in the "hot zone" of the chamber—specifically covering three-quarters of the area directly exposed to the blast stream—to prevent steel shot from striking the chamber's outer walls; these plates are suspended for easy installation, removal, and replacement.
3. A three-layer sealing structure is installed at the top to prevent steel shot from leaking out during the blasting process.
4Step-action pneumatic AB doors or continuous light curtain sensing system.
1. The shot blasting chamber features a compact structure and a sealed design based on German technology, ensuring that abrasive media does not scatter during operation.
2. The door utilizes an automatic opening and closing mechanism controlled by pneumatic cylinders.
3.Employing specialized processes and technology, the door is more reliable than conventional designs; it resists deformation and maintains its sealing integrity for 20 years—overcoming the performance degradation typical of traditional sealing methods after just six months.
1. Two sets of light curtain sensors are installed at the inlet and outlet, respectively; used in pairs, the sensor density can be selected based on workpiece size.
2. When a workpiece enters the blast chamber, the inlet light curtain detects its arrival, triggering a delayed start of the blast wheel. A light curtain sensor is also installed at the outlet; when the sensors at both the inlet and outlet detect no workpieces, the flow valve automatically closes immediately to prevent "air blasting" (blasting without a workpiece present).
5Automatic Catenary System
1. One set of automatic closed-loop overhead conveyor system.
2. One set of tooling system, fabricated by welding wear-resistant steel rods after heat treatment (design can be customized based on specific customer requirements).
3. Variable frequency speed control, allowing speed adjustment according to shot blasting requirements.
5.1Y‑shaped guide rail and automatic hanger changeover system
1. One set of Y-track trolley systems enables continuous operation across two workstations. A pneumatic valve controls the track-switching mechanism. While one hoist unit is engaged in the shot-blasting process, the other is used for loading and unloading.
2. Two sets of tooling systems, fabricated by welding wear-resistant steel rods after heat treatment (designs can be customized to meet specific customer requirements).
3. Two sets of hoist systems featuring a four-section telescopic framework and a chain electric hoist mechanism, ensuring excellent stability.
6Sorting system
1. A mesh screen separator is connected to the elevator and positioned above the magnetic separator; fine material passes through the screen into the magnetic separator, while coarse material and impurities are conveyed by a spiral mechanism along the screen to the discharge port at the rear.
2. It is designed to finely separate usable shot, broken shot, and dust, ensuring the uniformity of the shot media.
3.Featuring a welded structure, the interior contains multiple carefully designed compartments for airflow guidance. An access door on the front allows for routine inspection and maintenance; this door is equipped with an air inlet to provide the necessary airflow for dust separation.
4. An adjustable multi-vane baffle structure is used to regulate the uniformity of the falling abrasive curtain.
5. Stationary magnets installed at both the top and bottom enable the fine separation of usable shot from broken steel shot, ensuring the consistency of the blast media.
6. A storage hopper is connected at the bottom; after separation, the usable shot flows into the hopper for storage and subsequent reuse.
7Electrical control cabinet
1. Siemens PLC and touch screen
2. Siemens variable frequency drive (VFD) for speed control
3. Schneider low-voltage electrical components
4. Shot blasting time controller
5. AirTAC pneumatic components
6. Ammeter for flow monitoring
7. 1 lighting fixture
8. Dedicated constant-temperature air conditioning unit (optional)
