Technical Pain Point Eliminator: Three Solutions to Solve the Chronic Problem of Wet Material Screening
Traditional metal dewatering screens have long suffered from three major flaws:
Frequent Blockage: Material stuck in seams causes an average of 3-4 daily downtimes
Inefficient Maintenance: Localized wear requires complete replacement, costing over 120,000 yuan annually
Inadequate Dehydration: Coal slime adheres to the metal, resulting in product moisture content as high as 18%
Huatong Group's Innovative Modular Polyurethane Screen panel Solution:
► Tongue-and-groove quick-connect structure: Module gap <0.3 mm + 140° conical screen holes → Blockage rate ↓90%
► Independent unit design: Local damage can be replaced individually → Consumable costs ↓60%
► Micro-textured surface: Polyurethane tensile strength is 40% lower than metal → Coal slurry shedding rate ↑3 times
Test results: After dewatering, coal moisture content decreased from 18% to 13%, reaching industry-leading standards
Significant improvement in production line efficiency: From laboratory testing to thousand-ton-scale validation

“Reducing the weight of the screen panel by 50% directly reduces equipment load and significantly lowers failure rates” — Wang Wei, Technical Director of the Factory
⚙️ Ultra-durable design: redefining the standard for screen panel lifespan
Extreme environment validation: 12-month lifespan under 80°C hot water circulation conditions
Fatigue testing: passed 5,000 mechanical impact tests (ISO 9001-certified laboratory)
Patents: 3 utility model patents granted, invention patent under substantive examination
National energy-saving potential: Annual electricity consumption of 3 billion kWh for coal washing and dewatering → Modular technology saves 450 million yuan in annual electricity costs
Multi-sector applications: Adaptability verified for mine tailings dewatering and municipal sludge treatment scenarios
Policy-driven: Environmental protection zero-emission requirements are accelerating the replacement of metal screens
Technical trend outlook: Modular design is driving the upgrade of coal washing equipment toward “modular assembly + intelligent maintenance,” providing new pathways for carbon emissions reduction.
