Conveyor Shot Blasting Machine | Close Loop

Close Loop Conveyor Type Shot Blasting Machine is a type of shot blasting equipment designed for continuous cleaning, surface preparation, or finishing of metal components or workpieces. The system utilizes a closed-loop conveyor to transport the workpieces through the blasting chamber, ensuring an efficient and controlled process.

Key Features of a Closed Loop Conveyor Type Shot Blasting Machine:

1. Conveyor System:
   • The workpieces are transported using a closed-loop conveyor, which ensures smooth and continuous movement through the blasting area.
   • The conveyor may be a roller, belt, or chain type depending on the type of workpiece and the specific machine design.
   • The closed-loop nature means the conveyor is typically enclosed in a protective casing to prevent contamination and ensure operator safety.
2. Shot Blasting Process:
   • The shot blasting machine uses high-velocity abrasive materials (such as steel shot, grit, or sand) to clean, deburr, or improve the surface finish of metal parts.
   • The abrasive media is directed at the workpieces by centrifugal turbines or wheels within the blasting chamber.
   • The process removes rust, scales, old coatings, and other contaminants from the surface of the parts, or it may be used to create a textured surface (such as a matte finish).
3. Closed Loop Design:
   • The closed-loop conveyor ensures that once the parts are loaded into the machine, they pass through the blasting area continuously, often multiple times, to achieve uniform blasting.
   • After being blasted, the parts may be directed to a collection or unloading area, where they are removed from the conveyor.
4. Advantages:
   • Continuous Operation: The closed-loop conveyor ensures uninterrupted transport of workpieces, leading to higher throughput and reduced downtime.
   • Efficient Use of Space: Since the conveyor moves in a loop, these machines are space-efficient and ideal for high-production environments.
   • Consistent Quality: With the continuous movement of parts through the blasting chamber, the shot blasting process provides a consistent surface finish on all workpieces.
   • Closed Environment: The closed-loop design helps contain the abrasive media, preventing it from scattering and reducing contamination risks. It also provides better protection for the operator.
   • Recycling of Abrasive Media: The machine often includes systems for collecting and reusing the abrasive media, which can save costs on consumables.
5. Applications:
   • Cleaning: Removing rust, scale, or other contaminants from metal parts, such as castings, forgings, or welded components.
   • Surface Finishing: Preparing surfaces for painting, coating, or further machining by creating a uniform rough texture.
   • Deburring: Removing sharp edges, burrs, or imperfections from machined or cast parts.
   • Peening: Creating compressive stress on parts, particularly in the aerospace or automotive industries, to improve fatigue resistance.
6. Components:
   • Blast Wheel/Turbine: The device that propels the abrasive media at high speeds to blast the workpieces.
   • Dust Collection System: A system designed to capture and remove dust and debris produced during the shot blasting process to ensure a clean environment and reduce contamination of the workpieces.
   • Abrasive Recovery System: Ensures the reuse of the abrasive media by collecting and recycling it after use.
7. Automation and Control:
   • The system can be fully automated, with programmable controls for setting parameters like conveyor speed, blast intensity, and duration of exposure to abrasive media.
   • Sensors and monitoring devices ensure that the system operates efficiently, optimizing the shot blasting process for various workpieces.

Types of Closed Loop Conveyor Shot Blasting Machines:

1. Roller Conveyor Shot Blasting Machine: Suitable for heavy, large, and flat workpieces. These machines typically use a set of rollers to transport the parts through the blasting area.
2. Hanger Type Shot Blasting Machine: The workpieces are suspended by hooks or hangers and moved through the shot blasting chamber. This type is often used for complex or delicate parts.
3. Bucket Conveyor Shot Blasting Machine: Used for small to medium-sized components that are transported in buckets or containers.

Applications:

• Automotive Industry: Cleaning and finishing of cast automotive parts, such as engine blocks, cylinder heads, and transmission housings.
• Aerospace: Surface preparation and cleaning of parts like turbine blades or structural components.
• Foundries: Cleaning and preparing castings before further processing.
• Steel and Metal Industries: Descaling, rust removal, and surface finishing of metal products.

Shot Blasting Machine‘s > In summary, a Close Loop Conveyor Type Shot Blasting Machine is an efficient, continuous solution for blasting and surface finishing in industries where consistent, high-throughput results are required. It combines automation, recycling, and containment for a safe, productive, and environmentally-friendly shot blasting process.
