The grinding and dust-extraction workbench is an integrated, dry-type dust-removal system that combines a workstation, dust capture, purification/filtration, and automatic dust discharge. It is specifically designed for dry-process operations that generate dust, such as grinding, polishing, cutting, and deburring. The workbench surface features built-in suction inlets, allowing dust generated during operations to be captured on-site via negative pressure. The dust is then purified through an internal filtration unit, while an automatic pulse-jet cleaning mechanism regenerates the filter media, enabling continuous operation. With a dust-removal efficiency exceeding 99.5% and outlet emission concentrations as low as 10 mg/m³ or less, this unit significantly improves the workshop environment. It serves as a specialized dust-control solution for metal processing, as well as for grinding and polishing operations involving castings.

During grinding and polishing operations performed on the workbench, the dust generated is drawn downward and toward the rear—through intake ports on the workbench surface—into the unit’s internal chamber by means of negative pressure. Larger dust particles settle into the dust collection drawer at the bottom due to gravity, while finer particles are carried by the airflow into the filtration chamber, where they are captured by filter cartridges. Clean, filtered air then passes through the filter media and is exhausted from the unit by a fan. As dust accumulates on the surface of the filter media, the operating resistance of the system increases; a pulse controller then triggers electromagnetic pulse valves at set intervals, releasing a blast of compressed air (0.4–0.6 MPa) to dislodge the accumulated dust from the filter cartridges, causing it to fall into the collection drawer. This cleaning process does not interrupt ongoing grinding operations, and the dust collection drawer can be removed for periodic emptying, allowing for continuous equipment operation.

Dry Dust Treatment: For dry dust—both metallic and non-metallic—generated during processes such as metal grinding, casting polishing, weld grinding, deburring, and small-scale cutting.
Applicable Dust Types: Iron filings/dust, aluminum filings/dust, plastic dust, and composite material dust; can be configured with anti-static features for handling combustible dust.
Operating Temperature: Standard ambient conditions (≤60°C); not suitable for high-temperature flue gas, high-humidity environments, or highly adhesive dust.
System Negative Pressure: ≤3000 Pa.
Not suitable for dust-laden air containing moisture or significant oil/grease, which could cause the filter media to clog or "blind."

Widely used in sectors such as machining plants, hardware foundries, auto parts manufacturing, mold workshops, stainless steel processing, furniture hardware production, composite material processing, new energy component grinding, and handicraft polishing. It provides on-site dust collection for grinding, polishing, and deburring stations, and can also be integrated into production lines for targeted dust control.

High Dust Removal Efficiency: Filtration efficiency ≥99.5% with an outlet concentration ≤10 mg/m³; ensures a dust-free workshop environment and compliance with environmental emission standards.
On-Source Dust Capture: Dust is captured at the point of generation, preventing it from spreading throughout the workshop and improving the working environment for operators.
Automatic Pulse Cleaning: Features dual-mode (timed or pressure-differential triggered) pulse-jet cleaning, enabling long-term continuous grinding operations with minimal maintenance requirements.
Versatile Filter Media Options: Available with polyester, PTFE-membrane, or anti-static filter cartridges, suitable for various applications—from general dust to explosive or combustible particulate matter.
Robust and Durable Construction: Equipped with a thickened steel-plate work surface that is wear-resistant and impact-proof; the unit features a welded sheet-metal housing with a powder-coated, anti-corrosion finish.
Easy Operation and Maintenance: Includes a pull-out dust collection drawer at the base for simple debris removal, and a quick-access front maintenance door for rapid installation or replacement of filter cartridges.
Integrated Design: Combines a fan, filtration system, cleaning mechanism, and grinding workbench into a single, compact unit; easy to install—simply connect to a power source and it is ready for use.
