Recently, a fully automated recycling sandblasting booth customized by our company for a client in Dominica was successfully installed, commissioned, and officially put into production operation. The successful delivery of this equipment marks a further expansion of our company's market in the Caribbean region and provides the client with an environmentally friendly and efficient solution for the surface treatment of large workpieces.
The client is a local Dominica-based company specializing in shipbuilding, repair, and marine engineering equipment manufacturing. Its main businesses include ship repair, steel structure processing, and the manufacturing of large mechanical parts. With the increasing demand for local maritime services and marine engineering, the client has placed higher demands on the efficiency, quality, and environmental protection of surface cleaning for large workpieces.
Before introducing a specific case, let's briefly explain the applicable workpiece range of the fully automated recycling sandblasting booth to help understand why the client chose this equipment.
The fully automated recycling sandblasting booth is a closed, large-scale sandblasting operation space equipped with an automatic abrasive recovery system. It is particularly suitable for the surface treatment of the following types of workpieces:
**Shipbuilding and Repair Workpieces** This includes large ship components such as hull plates, bulkheads, section structures, propellers, and rudder blades. The sandblasting booth can accommodate ship hull sections tens of meters long, completing large-area cleaning in one go.
**Large Steel Structural Components**
Including bridge steel structures, building steel components, large welded structural components, embedded parts, etc. Sandblasting removes scale and rust, providing a good surface base for anti-corrosion coating.
**Marine Engineering Equipment**
Including offshore platform components, drilling equipment parts, subsea pipelines, floating bodies, etc. The marine environment has high requirements for corrosion resistance, making sandblasting an indispensable process before coating.
**Heavy Machinery Components**
Including large castings, forgings, mining machinery parts, engineering machinery structural components, etc. The sandblasting booth can accommodate heavy workpieces weighing several tons each.
**Wind Power Equipment**
Including wind turbine tower sections, blade molds, nacelle covers, etc. Wind power equipment has high requirements for surface treatment quality, and sandblasting provides ideal surface roughness for anti-corrosion coatings.
The client's existing equipment uses an open-type sandblasting operation, which presents the following problems in actual use:
**Environmental Compliance** Open-type sandblasting results in severe dust dispersion, failing to meet increasingly stringent local environmental regulations and hindering normal production.
**Abrasive Recycling Impaired** Abrasives are discarded after single use, leading to high consumption and operating costs. Waste sand disposal also increases the environmental burden.
**Highly Affected by Weather** Open-type sandblasting is limited by weather conditions; it cannot operate on rainy or windy days, affecting production progress.
**Poor Working Environment** Dust permeates the air, affecting operator health, and low visibility impacts work quality.
The client desires a new, enclosed, environmentally friendly sandblasting system with automatic abrasive recycling to reduce operating costs.
Based on the client's workpiece size and production volume requirements, our technical team customized a fully automated recycling sandblasting chamber, with the following main configurations:
**Fully Enclosed Sandblasting Chamber** Constructed with a steel structure and composite sandwich panels, ensuring a robust structure and excellent sealing. Dimensions are customized based on the customer's largest workpiece and factory conditions, accommodating large ship sections and steel structural components.
**Automatic Abrasive Recovery System** Employing a mechanical recovery method, the system automatically collects used abrasive materials to a separator via a screw conveyor and bucket elevator. After screening, intact abrasive materials are recycled, resulting in high recovery efficiency and significantly reduced abrasive consumption.
**High-Efficiency Dust Removal System** Equipped with a high-power cartridge dust collector, the airflow is matched to the sandblasting chamber volume to ensure a negative pressure environment within the chamber, preventing dust escape. Emission concentrations meet Caribbean environmental standards.
**Intelligent Lighting and Monitoring System** The chamber is equipped with explosion-proof LED lighting, providing ample brightness without blind spots. High-definition cameras are installed, allowing operators to monitor operations in real time from the control room.
**Safety Interlock System** Equipped with door opening interlocks, emergency stop buttons, and internal emergency door opening devices to ensure operator safety.
**PLC Control System** Enables centralized control of functions such as one-button start, automatic recovery, and automatic dust removal, offering simple operation.
After the equipment was put into operation, the customer's efficiency in sandblasting large workpieces significantly improved. The fully enclosed sandblasting booth is unaffected by weather, allowing for 24/7 operation, and production plans are no longer limited by the weather.
The automatic abrasive recovery system significantly reduces steel shot consumption, resulting in a substantial decrease in operating costs. Dust emissions meet standards, and the equipment successfully passed the local environmental protection department's inspection.
The customer's production manager stated, "This fully automated recovery sandblasting booth has solved our long-standing environmental and efficiency problems. Sandblasting operations are no longer affected by weather, abrasives can be recycled, and operating costs have been significantly reduced. The workshop environment is also much cleaner, and workers report a significant improvement in working conditions."
The fully automated recovery sandblasting booth delivered this time, through its fully enclosed structure, automatic abrasive recovery system, and high-efficiency dust removal system, helped the customer achieve an environmental upgrade and efficiency improvement in sandblasting operations, solving the environmental and cost issues of open sandblasting.
This case also further validates the application value of fully automated recovery sandblasting booths in the surface treatment of large workpieces in shipbuilding, large steel structures, and marine engineering equipment. Our company will continue to monitor equipment operation and provide timely technical support and after-sales guarantee for our customers.
A: Fully automatic recycling sandblasting booths are suitable for cleaning large and heavy workpieces, including ship sections, hull plates, bridge steel structures, large welded structural components, marine engineering equipment, wind turbine towers, heavy machinery parts, large castings and forgings, etc. Workpieces can be tens of meters long and weigh several tons.
A: There are two main recycling methods. Mechanical recycling uses screw conveyors and bucket elevators, which have a simple structure and low maintenance costs, suitable for medium to large-sized sandblasting booths. Pneumatic recycling uses high-pressure blowers for negative pressure suction, resulting in cleaner recycling. It requires a shallower pit and is suitable for locations with high cleanliness requirements.
A: Most sandblasting booths require a pit for installing the abrasive recycling system. The pit depth is generally between 500 and 1000 mm. If the site does not allow for digging a pit, a surface-mounted recycling solution can be designed, but the equipment cost will differ. Please confirm the specific solution with our technical team during the selection process.
A: Yes. The sandblasting booth is equipped with a high-efficiency cartridge dust collector, and the emission concentration can be controlled below 10 mg/m³, meeting international environmental standards. Specific emission standards can be configured according to local environmental requirements.
