The climbing frame shot blasting machine manufactured for Foshan, Guangdong has won high praise from the customer!
Pass-through Climbing Frame Shot Blasting Machine
This versatile pass-through shot blasting machine handles both construction climbing scaffolds and mesh panels; it features fourteen blast wheels for comprehensive, multi-directional shot blasting and rust/scale removal, delivering excellent results for construction machinery, climbing scaffolds, and mesh panels.
Working Principle of Pass-through Climbing Frame Shot Blasting Machine is as follows:
The climbing frame moves along a roller conveyor system; as it enters the cleaning chamber, the shot blasting machine begins its sequential operation. The process removes mill scale, dirt, and other deposits from the surface, resulting in a smooth, clean finish. The machine operates on a continuous, cyclical basis.
The abrasive shot discharged by the blast wheel is collected and processed by a circulation system for reuse. The circulation process operates as follows: scattered shot is conveyed via a lower longitudinal screw conveyor and an inclined chute to a bucket elevator; the bucket elevator lifts the shot and debris to the top of the blast chamber, where an upper transverse screw conveyor feeds the mixture into a high-efficiency BE separator; within the separator, dust and debris are removed from the usable shot, which is then stored in a hopper, ready for supply to the blast wheel.

Introduction to the Components of the Shot Blasting Machine
1Blast wheel
1. 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%.
2. features a more compact footprint than traditional blast wheels, supports arbitrary installation angle arrangement, and enables far easier inspection and maintenance.
3. Constant blasting performance is maintained throughout operation, free from inconsistent and fluctuating cleaning quality seen on conventional units.
4. 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.
5. 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.
6. Equipped with SKF bearings imported from Sweden.
7. Fitted with genuine Siemens motors.
8. German Schenck dynamic balancing tester is applied to guarantee precise high-speed dynamic balance of impeller hubs.
2Flow control 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.
4Variable-frequency automatic speed-regulating conveyor system (comprising an infeed roller conveyor, a shot-blasting zone roller conveyor, and an outfeed roller conveyor with automatic speed regulation)
Roller conveyor pass-through type:1. The workpiece conveying system for the entire production line utilizes stepless variable-frequency speed control and consists of an input roller conveyor, a shot-blasting chamber roller conveyor, and an output roller conveyor.
2. The rollers for both the input and output roller tables are manufactured by welding heat-treated shaft ends to high-quality carbon steel seamless pipes, followed by integral machining on a lathe. Machining is performed after welding to ensure both a load-bearing capacity of 0.5 t/m and precise coaxiality.
3. The rollers within the shot blasting chamber that are subjected to the impact of the shot are all fitted with easily replaceable, wear-resistant sleeves made of special high-chromium-molybdenum iron.
4. The roller pitch is 600–800 mm, and the entire line utilizes variable-frequency speed control, enabling both high-speed and low-speed workpiece transport.
Wire mesh-belt conveyor type:
1. The system comprises dozens of transmission components, including carbon steel rollers, sprockets and chains, mesh belts, and bearings. The roller conveyor is divided into three sections: the infeed section, the shot-blasting section, and the discharge section. The rollers are constructed by precision-welding quenched-and-tempered end caps to high-quality seamless carbon steel pipes; their profiles and mounting dimensions are machined after welding to ensure compliance with load-bearing and coaxiality requirements.
2. The roller conveyors inside the blast chamber are equipped with easily replaceable wear-resistant medium-chromium cast iron sleeves. Labyrinth seals made of wear-resistant manganese steel are used at both ends of the roller shafts, completely preventing abrasive media from wearing down the bearings.
3. Utilizes imported HD wear-resistant manganese steel that has undergone solution and tempering treatments to eliminate internal residual stresses, moderately reduce the hardness of the manganese steel wire, and enhance its toughness and ductility.
4. A geared drive motor is installed on the right side of the conveyor belt and directly coupled to the drive roller, propelling both the belt and the workpieces; variable frequency speed control is employed, providing a conveying speed of 0.5–4 m/min.
5. A roller is installed under the driving shaft to serve as a guide and tensioner. When the steel mesh belt is loose, it can be tightened through this mechanism.
5Light curtain sensing system, automatic loading system/automatic unloading system
1. Two sets of light curtain sensing units are installed at the infeed and outfeed openings, respectively; the light curtain resolution can be selected based on workpiece size, and the units are used in pairs.
2. When a workpiece enters the shot blasting chamber, a light curtain at the inlet detects its presence, triggering a delayed start of the blast wheels. A light curtain sensor is also installed at the outlet; when the inlet and outlet sensors detect that no workpieces are passing through, the flow valve closes automatically and immediately to prevent "air blasting" (blasting without a workpiece present).
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.
