Shot Peening & Blasting Machines
Our industrial surface treatment equipment including shot blasting machines, powder coating systems, and metallizing solutions optimize metal processing operations for manufacturers globally.
Blasting pots are high-pressure steel containers in dry abrasive blasting systems that store and propel abrasives like sand or steel grit using compressed air. They include pressure regulators and nozzle controls to adjust abrasive flow and speed.
Blasting cabinets are enclosed, compact units for precision dry abrasive blasting. Housing nozzles, work stations, and dust collectors, they use compressed air to propel media (grit, glass beads) for deburring, cleaning, or finishing small workpieces.
Containerized blasting rooms are portable, self-contained units housed in shipping containers for on-site abrasive blasting, fully enclosed to contain dust and ensure environmental compliance and operator safety.
Shot blasting rooms are used for surface pretreatment of large workpieces, spraying sand or abrasives with compressed air. They feature a blasting station, dust removal system, and abrasive recovery unit, with customizable sizes for various industrial applications.
Inside surface shot peening machine treats inner surfaces of gas cylinders, water heaters, cartridge cases, and fire extinguisher bottles with precision compressive stress. It features a retractable rotating nozzle, shot delivery recovery unit, clamping mechanism, and CNC-controlled peening path, angle, and intensity.
Designed for sandblasting the inner walls of pipes, it achieves full-process automated control through the regulation of multiple variables such as pipe diameter, pipe length, rotation speed, sandblasting pressure, nozzle speed, and purging pressure, ensuring quality consistency and high production efficiency.
Internal cylindrical sandblasting machine blasts the inner walls of parts like hydraulic cylinders. It features an adjustable rotating nozzle, abrasive recovery, and clamping device, with high concentricity for full inner-wall coverage.
Automatic shot peening systems are engineered for reliable surface enhancement, delivering consistent and effective results on a variety of metal parts. Their robust construction and advanced features make them ideal for industrial applications.
Disa offers an extensive portfolio of wheelblasting equipment and can provide complete shot blasting solutions to meet customer requirements.
Disa high performance blast wheel deliver ideal flow properties, ensuring high throughput and excellent blasting performance with a wide, uniform hot spot for outstanding results.
Disa provides complete blasting media solutions from steel grit to ceramic beads, backed by three decades of metal surface treatment innovation.
Portable shot blasters use centrifugal wheels to propel steel shot, preparing concrete floors by removing coatings and creating the ideal profile for overlays.

Disa high-performance blast wheels deliver ideal flow properties, ensuring high throughput and superior blasting performance. With a wide, uniform hot spot, they achieve outstanding, consistent surface treatment results.
Built from high-chrome alloy cast steel, these wheels offer exceptional abrasion resistance and extremely high output. Fully statically and dynamically balanced, they deliver reliable high productivity across the most demanding applications.
The blast wheels are equipped with a precision adjustment valve, allowing exact control of the abrasive flow rate to meet the specific requirements of any blasting process.
DISA supplies customized, wear-resistant parts that extend service life, reduce replacement frequency, and lower overall maintenance costs.
such as roller conveyors, overhead monorails, or turntables,move parts steadily through the blast zone for uniform cleaning, descaling, or surface preparation. The choice of system depends on part size, shape, production volume, and process needs, ensuring smooth integration into automated lines and efficient blasting performance.
Disa electrical control system features a free-standing NEMA 12 / IP54-rated panel with UL-listed and NEC-approved components. It includes a Siemens PLC, touchscreen, and frequency converter, along with Schneider electrical components such as IEC-rated starters, fuses, overload relays, and contactors.

Spare parts replacement procedures
Before opening any safety doors, access panels, or removing protective guards, you must strictly follow these safety procedures:
Power Down: Turn the main switch to the "0" (OFF) position.
Prevent Accidental Start-up: Ensure the machine cannot be operated accidentally (e.g., using lockout/tagout procedures).
Post Warnings: Hang clear warning signs to indicate that maintenance work is in progress.
Since flying abrasives, sharp flashes and burrs may cause personal injury, safety goggles and safety helmets must be worn at all times.
Activating this safety interlock triggers an immediate emergency stop of the blast wheel drive. This action shuts down the entire shot blasting machine and halts the material feed system.
The blast wheel must only be operated when the housing covers and feed pipes are properly fitted and secured.
There is a significant entanglement hazard from the moving buckets while the elevator is in operation. To prevent injury, all access points—including maintenance guards, inspection covers, and the elevator's top cover—must be closed and securely fastened with bolts before operating the shot blasting machine.
1. Mechanical Hazard: The rotating magnetic drum presents a serious risk of entanglement and physical injury. Never place hands or any body parts near the drum while it is in operation.
2. Magnetic Field Hazard: The magnetic drum generates a powerful magnetic field, which is life-threatening for individuals with pacemakers. Personnel with such medical devices are strictly forbidden from approaching the magnetic separator and must maintain a safe distance at all times.
The hook-type shot blasting machine ensures uniform surface cleaning and strengthening through the following processes:
1. Workpiece Suspension & Rotation
Workpieces are hung on a hook trolley driven by a three-phase gear motor. Inside the chamber, the hook employs a bidirectional swinging and rotating motion, ensuring even exposure to the shot flow. The shot blasting head speed (1500-3200 RPM) is adjustable via a frequency converter to suit various workpieces.
2. High-Speed Shot Blasting
Driven by a Siemens motor, the direct-drive impeller (φ380 mm) features 8 high-chromium alloy blades (55 HRC). Abrasive shots are accelerated and impact the workpiece at speeds up to 73 m/s, with coverage intensity precisely controlled by the head's rotation speed.
3. Shot Recycling & Separation
Used shots and debris are transported via a bottom screw conveyor and bucket elevator (manganese steel buckets) to an air separation system. Impurities are removed through gravitational and magnetic separation, while clean shots are recycled into the hopper.
4. Dust Treatment
A two-stage filtration system ensures clean air discharge:
Primary cyclone separator: Removes large particles.
High-efficiency bag filter: Captures micron-sized dust (>99% efficiency).
Purified air is discharged via a negative pressure system (38,000 m³/h), with noise controlled at ≤85 dB(A).
5. Automation & Safety
PLC Control: Manages blasting time, head speed, and hook movement.
Safety Interlocks: Pneumatic doors automatically lock during operation.
Protection: Equipped with emergency stop buttons and vibration monitoring to prevent overloading.
