Recenty I discovered a News that drones can now be equipped with Sand blasting Guns so that  they can perform jobs like Sand blasting , Shot blasting and thermal Spray Painting
Since the operation is in limited space therefore Batteries can be replaced with a AC /DC power supply via wire to reduce battery Weight ,
Subsiquiently that increased Payload can be used to equipp the drone with Sand blasting guns and can be emits various ABrasives like Aluminium Oxide
  or Even Silicon Carbide Grit
Is that True??

If yes can anyone give me link to buy it , If its DJI ,  I will be more happy

DJI only have sprayers currently for pesticides or feed.

Aluminium Oxide  or Silicon Carbide

That sounds interesting.

Steel Shots are a versatile and cost-effective abrasive media used in many different industries and applications, such as cleaning, surface preparation, deburring, and finishing. Steel Shots are round metallic beads made of low carbon steel and are available in various sizes and grades. Steel Shots are used in shot blasting and air blasting machines to clean, polish, and finish surfaces. It is also used to remove rust, scale, and other surface contaminants.

Shot Blaster offer quality steel shots at competitive prices. The steel shots are available in various sizes and grades that are suitable for different applications. The suppliers offer the steel shots in bulk quantities to meet the demands of the customers. The suppliers ensure that the steel shots are delivered within the specified time frame and in good condition.

The suppliers also provide technical assistance to the customers for the selection of the right size and grade of steel shots for their applications. https://www.steelshots.co/

Using a drone as a sandblaster in industrial applications is an innovative approach to surface preparation and cleaning tasks. Sandblasting, traditionally done by handheld equipment or large machines, involves forcibly propelling abrasive materials (such as sand or abrasive media) onto a surface to remove rust, paint, contaminants, or other unwanted materials. Using a drone for sandblasting can offer several advantages in certain industrial scenarios:

**1. Access to Hard-to-Reach Areas:** Drones can access areas that are difficult or dangerous for humans, such as tall structures, confined spaces, or areas with hazardous materials. This makes them particularly useful for tasks like cleaning the exterior of industrial tanks, bridges, or towers.

**2. Safety:** By using a drone, you reduce the risk of exposing workers to hazardous environments, such as toxic chemicals or high scaffolding. This enhances safety and minimizes the need for extensive safety measures.

**3. Precision and Consistency:** Drones equipped with sandblasting equipment can provide precise and consistent coverage, ensuring uniform surface preparation. This is crucial in industries where adherence to strict quality standards is necessary.

**4. Efficiency:** Drones can work quickly and efficiently, covering large surface areas in a shorter amount of time compared to manual labor or traditional sandblasting equipment. This can lead to cost savings in terms of labor and downtime.

**5. Reduced Environmental Impact:** Using a drone for sandblasting can result in fewer emissions and less environmental impact compared to traditional sandblasting methods, which can release airborne contaminants.

**6. Remote Operation:** Drones can be operated remotely, allowing operators to control the sandblasting process from a safe distance. This is particularly beneficial in situations where close proximity to the work area is challenging.

**7. Real-time Monitoring:** Some advanced drones come equipped with cameras and sensors that allow operators to monitor the progress of the sandblasting operation in real-time, ensuring that it is proceeding as planned.

**Challenges and Considerations:**

1. **Abrasive Media Management:** Managing and replenishing the abrasive media (such as sand or grit) on the drone can be challenging and may require frequent refilling.

2. **Equipment Reliability:** Ensuring the reliability and durability of the drone and sandblasting equipment is crucial, as industrial environments can be harsh.

3. **Regulations:** Regulatory considerations, including safety standards and environmental regulations, must be adhered to when using drones for industrial sandblasting.

4. **Cost:** Initial setup costs for specialized sandblasting drones and equipment can be relatively high.

5. **Training:** Operators require specific training to safely and effectively operate sandblasting drones.

6. **Surface Compatibility:** The type of surface being blasted and the abrasive media used must be compatible to achieve the desired results without causing damage.

Using drones for sandblasting in industrial applications is an emerging field with the potential to improve efficiency and safety. However, it's essential to carefully assess the specific requirements of each application and consider the challenges and costs associated with this technology before implementation. Additionally, compliance with regulatory standards and safety protocols is critical when using drones in industrial sandblasting operations.
