Industrial Wet Grinding Table For Flammable Metals Like Aluminum And Magnesium

Product Specification

1. Purpose-Built for Aluminum & Magnesium Grinding Safety

2. Wet Dust Suppression Technology Optimized for Light Metals

• Continuous Water Curtain: A 5mm-thick water film flows evenly across the 1.2m x 0.8m worktop, created by a precision manifold with 0.5mm-diameter nozzles. This film traps 99.5% of aluminum and magnesium dust particles (down to 0.1μm) before they become airborne, eliminating the risk of dust cloud formation—the primary cause of explosions in dry aluminum grinding setups.
• Sludge Separation System: A built-in cyclonic separator filters aluminum and magnesium sludge from the coolant, allowing clean water to recirculate. The sludge (containing 70% metal content) can be safely collected and recycled, reducing waste and creating a secondary revenue stream for metal shops.
• Anti-Oxidation Coolant: The recommended coolant blend includes a corrosion inhibitor that prevents aluminum and magnesium sludge from oxidizing (a process that can generate heat and increase fire risk) and avoids surface pitting on finished parts. This is critical for high-precision aluminum components like aerospace brackets or magnesium alloy engine parts.

3. Safety-Centric Design for Flammable Metal Operations

• Fire Suppression Backup: In addition to the wet system, the table is equipped with a built-in dry chemical fire extinguisher (rated for Class D fires—specific to combustible metals) mounted under the worktop. It activates automatically if a thermal sensor detects temperatures above 80°C, a sign of incipient fire.
• Non-Sparking Components: All exposed parts (e.g., worktop edges, tool holders, coolant manifold) are made from non-sparking brass or aluminum-bronze alloy. This eliminates the risk of sparks from metal-to-metal contact during grinding, which could ignite magnesium dust.
• Sealed Electrical Systems: The table’s motor, control panel, and sensors have an IP67 ingress protection rating, fully sealed against water and dust. Electrical components are also rated for Class I, Division 2 hazardous locations, compliant with standards for areas where flammable metal dust may be present.

4. Performance & Efficiency for Aluminum/Magnesium Workflows

• Adjustable Coolant Flow: A variable-speed pump lets operators adjust coolant flow (5–15 L/min) to match grinding intensity—higher flow for aggressive aluminum deburring and lower flow for precision magnesium polishing (to avoid coolant splashing on delicate parts).
• Vibration-Damped Worktop: The 10mm-thick aluminum alloy worktop is reinforced with a rubber underlay to minimize vibration, ensuring consistent grinding depth for tight-tolerance parts (e.g., ±0.003mm for aluminum aerospace fittings).
• Ergonomic Design: The table height is adjustable (750–900mm) to suit different operators, and a 150mm-tall splash guard along the back edge contains coolant spray—keeping work areas clean and reducing operator fatigue during long grinding shifts.

5. Compliance & Durability for Hazardous Metal Shops

• Global Safety Certifications: It meets OSHA 1910.178 (flammable metal handling standards), NFPA 484 (standard for combustible metals), and EU ATEX 2014/34/EU (for equipment in explosive atmospheres). This is critical for shops working with aluminum and magnesium in regulated industries like aerospace, defense, and automotive.
• Corrosion-Resistant Construction: The frame is made from 304 stainless steel, powder-coated with a chemical-resistant finish to withstand exposure to coolant and aluminum/magnesium sludge. The coolant tank is lined with PVC to prevent rust and ensure a 10+ year service life.
• Low-Maintenance: The cyclonic separator has a tool-free access door for easy sludge removal, and the coolant filter can be replaced in 5 minutes—minimizing downtime for busy aluminum and magnesium grinding operations.
