Three Core Advantages: Deep Adaptation to Industrial Scenarios
一、Powerful Performance × Four-Disc Synergy: Conquering High-Intensity Grinding Tasks
✅ Ideal for Heavy-Duty Applications
· The 22kW pure-copper motor paired with a Weichuang frequency converter delivers stable torque, easily tackling hard surfaces like C30–C50 high-strength concrete, quartz sand wear-resistant layers, and thick epoxy coatings.
· Four grinding discs operate synchronously with an 850mm grinding width, boosting efficiency by 300% compared to traditional single-disc machines. It can process 6,400 m² in 8 continuous hours—equivalent to the area of a standard football field.
✅ Versatile Grinding Disc System
· Supports 3 disc types (metal, resin, diamond soft pads) for quick mode switching: rough grinding/leveling (5mm depth removal) and fine grinding/polishing (Ra0.2μm surface precision).
· Low disc consumption of 0.3 RMB/m²; planetary gearbox ensures uniform force distribution, extending disc life by 20%.
二、Industrial-Grade Durability: Stable Operation in Harsh Environments
All-Metal Heavy-Duty Body
· Gearbox made of high-strength cast steel, capable of bearing 2000kg, resistant to forklift 碾压 and heavy impacts in harsh conditions.
· IP54 waterproof rating allows direct water 冲洗，meeting cleanliness requirements for food processing plants and chemical workshops.
Easy Maintenance Design
· Modular structure: Independent disassembly of motor, gearbox, and grinding disc components reduces daily maintenance time by 50%.
· Requires 10mm² national standard cables; standard overload protection prevents damage from power fluctuations.
三、Multi-Scenario Adaptability: From Infrastructure to Commercial Floors
️ Heavy Industry Applications
· Bridge Pavement: Rapidly removes concrete laitance, creating a rough interface for asphalt laying (pull-off strength increased by 40%).
· Warehouse Logistics: 850mm wide grinding width processes 20,000 m² daily, ensuring shelf installation flatness error <1mm.
· Airport Runways: Adjustable 300–1800r/min speed enables one-stop construction for rough anti-slip textures and fine flatness.
Commercial Renovation Applications
· Shopping Malls: Resin discs polish marble to 85° gloss, enhancing hardness to Mohs 7 with curing treatment.
· Factory Renovation: Four discs remove old epoxy coatings 20x faster than manual chiseling, with dust collection efficiency ≥95% (with industrial vacuum).
