Explosion Proof Wet Water Curtain Grinding Workbench for Metal Polishing & Deburring Dust Collection
Under-suction explosion-proof grinding tableUnder-suction explosion-proof grinding tableThis wet water curtain grinding workbench is specially engineered for metal polishing, casting deburring, hardware grinding, alloy surface finishing, especially ideal for processing flammable metal dust like aluminum, magnesium, zinc and titanium alloy. Different from dry filter downdraft tables, it uses water curtain wet dust capture technology to eliminate hidden danger of dust explosion, fullycomply with international environmental and workshop safety standards, widely approved for factory environmental assessment inspection across global metal processing industry.
Available in customized single/double/multi-station specifications, standard sizes include 1000mm, 1500mm, 2000mm, 3000mm length, carbon steel as standard material, optional full 304andCarbon steel stainless steel body for corrosive working condition.
Under-suction explosion-proof grinding tableWorking Principle of Water Curtain Dust Collection
Under-suction explosion-proof grinding tableThe built-in high negative pressure fan forms strong air suction on the work surface, all grinding dust is drawn into inner cavity of the bench:
1. Large coarse dust collides with front waterfall water curtain, captured and settled into bottom circulating water tank by water;
2. Tiny fine dust is caught by secondary top spray water mist, dust particles gain weight with water and sink down into sludge area;
3. Water circulates repeatedly via built-in water pump, metal dust accumulates at tank bottom for regular sludge cleaning, no filter cartridge needed, drastically cut daily maintenance cost compared with dry grinding table.
Full Explosion-proof Electric Control System
Under-suction explosion-proof grinding tableEquipped with certified explosion-proof control box, explosion-proof switches and explosion-proof driving motor, perfectly match high-risk workshop with combustible metal dust, pass international safety inspection for aluminum & magnesium processing factories. Two pressure gauges are reserved on both sides for real-time circulating water pressure monitoring.
Heavy-duty Double-station Working Surface
Grid anti-slip work platform supports max 200kg loading capacity, 2 workers operate simultaneously for high-efficiency polishing and deburring. Built-in explosion-proof inner lamp improves visibility for dim production workshop.
Integrated Water Storage Cabinet
Four-door enclosed cabinet at bottom contains circulating water tank, water pump and sludge sediment compartment, cabinet door is fully openable for convenient regular waste residue and sludge cleaning. Whole machine uses thick cold-rolled steel with electrostatic anti-rust coating, waterproof and anti-corrosion for long-term wet environment service.

Wide Application Industries
1. Aluminum, magnesium, titanium alloy casting polishing & deburring; 2. Auto wheel hub, valve, plumbing hardware surface finishing;
3. Stainless steel craft, jewelry, cutlery grinding and buffing; 4. Hardware stamping parts, die casting burr removing processing.
Product Advantages for Global Buyers
1. High Safety Explosion-proof Design: Wet dust collection completely avoids floating dry combustible dust, prevent dust explosion accident for flammable alloy processing;
2. Zero Consumable Cost: No filter cartridge replacement required, only regular water change and sludge cleaning, lower long-term operating expense;
3. Easy Installation: All-in-one integrated structure, finish installation just by connecting power supply and tap water inlet, no extra exhaust duct layout needed;
4. Flexible Customization: OEM & ODM acceptable, adjust bench length, material, station quantity according to clients’ on-site workshop demand.
Daily Maintenance Guide
Drain and clean bottom sludge 1~2 times per week, regularly check top spray nozzles to avoid clogging, add proper defoamer into circulating water when needed to optimize dust catching effect.
Our water curtain grinding workbench has gained positive feedback from global hardware foundry, auto parts factory and jewelry processing manufacturers. The explosion-proof polishing downdraft table solves the biggest safety pain of flammable metal dust processing, becoming a mainstream environmental dust removal equipment for modern metal finishing production lines. Regular simple maintenance can keep the whole grinding bench running stably for more than 16 years without big part replacement.
