Principle Overview:

The interior of the sandblasting room forms an air flow layer from top to bottom under the influence of wind, while the abrasive material is jetted onto the workpiece surface by compressed air, cutting away debris. Some of the abrasive debris breaks down into dust, which is then carried by the downward airflow, mixing with more abrasive material and rust particles, and returned to the separation system via the honeycomb back-sanding floor. After separation, reusable sand is returned to the storage bin and automatically added to the sandblasting system for recycling in accordance with the sandblasting requirements. Dust and impurities that cannot be reused are transported to a dust collector for fine filtration. The settled dust is collected in a waste bin and recycled, while the filtered gas is either released into the atmosphere or recycled for use in the sandblasting room. The entire process is enclosed, with no dust escaping, ensuring safety and environmental protection.

Mechanical circulation sandblasting room complete set mainly consists of the sandblasting room body, lighting system, air-powered recovery floor, separator, sandblasting system, dust collector, fan, control system, workpiece conveying system, and operator protection system.

Mechanical circulating sandblasting room features:

★ Eco-Friendly: The fan is driven electrically, ensuring cleanliness and pollution-free operation; sandblasting is conducted in a sealed environment, with sand material being recycled through enclosed pipes, thus preventing any sand or dust leakage and surrounding pollution; dust is filtered using a core filter, with the exhaust gas concentration after filtration exceeding national emission standards.

★Automatic Recirculation: The system utilizes an air-powered material recovery floor to achieve automatic recycling of sand materials.

★Dual-purpose: The wind generated by the fan not only meets the transportation of sand materials but also serves as a dust removal system.

★Automatic Sorting: The sorting equipment utilizes the principles of pneumodynamics to effectively separate sand, impurities, and dust, with recyclable sand returned to the storage bin, while non-recyclable dust and impurities are transported to the dust collector for refined filtration.

★ Filter Core Dust Removal: The system employs filter core dust removal method, ensuring high filtration efficiency.

★ Imported Filter Media: Made from imported long fiber material, offering a large filtering area, with each filter element having twice the filtering area of a standard filter element.

★Automatic Control: Automation is achievable for sand recycling, sorting, nozzle control, dust removal, sandblasting pot operation, and the system features automatic fault alarms and alerts.

★High Integration: The control system utilizes PLC + touch screen display, enabling both automatic operation mode and manual control mode.

★Efficient Cleaning: Utilizing a high-pressure dual-cylinder continuous sandblasting machine, a single nozzle can clean up to 10 ~ 30 m²/h.

Compared to traditional shot blasting rooms, it boasts the following distinct features:

No deep excavation required (or no excavation needed), low infrastructure costs, and short construction period.

2. Equipped with sand-suction flooring, eliminating the need for traditional conveying equipment such as augers, belt conveyors, and bucket elevators. This design avoids the wear, clogging, and other issues caused by sand and dust during transportation and lifting, resulting in a low failure rate and minimal maintenance workload.

3. Equipped with abrasive separation and sorting devices, the abrasive is automatically recycled, improving utilization rate and sandblasting cleaning efficiency.

4. The abrasive recycling separation, sorting, and dust removal systems share a single fan, achieving multiple uses with one wind source, saving 30% of energy compared to traditional sandblasting rooms.

5. The sandblasting system allows multiple high-speed nozzles to operate with a single sand pot, each nozzle can be controlled individually, offering high sandblasting efficiency, and the working pressure can be infinitely adjusted.

6. Utilizes carbide-toughed sandblasting nozzles with an average lifespan of 800-1000 hours.

7. The sandblasting room can utilize different materials and grain sizes of abrasive media (such as steel shots, glass beads, steel grit, quartz sand, copper ore sand, yellow sand, fruit shells, etc.), meeting various processing requirements.

8. The sandblasting (bead) room features an indoor air circulation from top to bottom, with bright lighting, comfort, and high visibility.

9. Utilizing filter core dust removal technology, the dust emission from the shot blasting room is significantly lower than the national environmental protection standards.

10. The sandblasting (ball) room is constructed with foam sandwich color steel panels, featuring noise reduction capabilities, and is aesthetically pleasing, sturdy, and airtight.

Dust and Sand Separation System

The materials and dust recovered from the honeycomb floor must be separated by a sand and dust separator before the sand can be recycled. The efficiency of the sand and dust separator directly impacts the sandblasting performance of the sandblasting machine and the filtration performance of the dust collector.

The sand dust separator uses a two-stage air separator specifically designed for our shot blasting systems. The first stage is a unique cyclonic inertia separator, and the second stage is an airflow backblowing separator. It effectively sorts recycled reusable sand, crushed sand, dust, oxide scale, and other contaminants. The whole sand is returned to the shot blasting machine's main unit for continuous reuse, while the dust and crushed sand are sent to the dust collector, filtered, and stored until scheduled cleaning.

Adjusting the regulating mechanism on the dust separator allows for the regulation of the diameter of the separated sand material. Custom-designed dust separators can achieve gradation, segmentation (different particle sizes), and round selection of sand material.
