Explosion-Proof Wet Polishing & Dust Collection Integrated Machine: Safety-First Solution for Hazardous Polishing Tasks
Our explosion-proof wet polishing & dust collection integrated machine is a specialized industrial equipment engineered to deliver safe, efficient, and dust-free polishing and (grinding) performance in explosive or flammable environments. By combining advanced wet dust suppression technology with strict explosion-proof design (compliant with global hazardous area standards), it eliminates the risk of dust explosions while ensuring high-quality surface finishing—making it an indispensable tool for industries like metal processing (aluminum, magnesium), chemical, pharmaceutical, and oil & gas across global markets.
Core Advantages & Performance Highlights
- Certified Explosion-Proof Safety: Adopts an explosion-proof structure (Ex d IIB T4 Ga/Ex ia IIB T4 Ga) and uses explosion-proof motors, electrical components, and wiring (compliant with ATEX, IECEx, UL 1203, and GB 3836 standards). The sealed wet processing chamber prevents the accumulation of flammable dust (e.g., aluminum dust, magnesium dust) and eliminates ignition sources, ensuring safe operation in Zone 1/2 (gas) and Zone 21/22 (dust) hazardous areas.
- Efficient Wet Dust Collection: Integrates a high-pressure water mist system (10–15MPa) and cyclone dust separator, capturing 99.9% of polishing dust (particle size ≥ 0.5μm) at the source. The water-dust mixture is collected in a sealed sludge tank, avoiding secondary dust pollution—critical for protecting operator health and complying with environmental regulations (e.g., EPA, EU ETS).
- Dual-Function Polishing & Grinding: Equipped with replaceable polishing pads (for fine finishing) and grinding discs (for rough shaping), supporting processing of metals (aluminum, copper, stainless steel), composites, and stone. The variable-speed motor (500–3000rpm) allows adjustment of processing intensity to match material hardness, ensuring uniform surface quality (Ra ≤ 0.4μm for fine polishing).
- Intelligent Operation & Monitoring: Features a 7–10 inch explosion-proof touchscreen HMI (with anti-glare and waterproof design) and PLC control system. Enables real-time monitoring of water pressure, motor temperature, and dust collection efficiency, with automatic alarms for abnormal conditions (e.g., low water level, motor overload). Supports parameter storage (up to 100 sets) for different processing tasks.
- Durable & Low-Maintenance Design: Constructed with corrosion-resistant 316L stainless steel (for the processing chamber and sludge tank) and wear-resistant silicon carbide grinding components, ensuring long-term use in humid and dusty environments. The self-cleaning water filter reduces sludge buildup, and quick-change polishing/grinding heads minimize maintenance downtime (replacement within 3 minutes).
