Recent industrial trials have revealed that HUATAO Group’s spliced polyurethane screen panels are revolutionizing coal processing by overcoming the limitations of traditional metal screens:

  • Efficiency Leap: Coal dewatering efficiency has risen by 20%, with a single plant now processing over 8,000 tons daily.
  • Cost Cuts: Screen replacement time dropped from 4 hours to 1.5 hours, trimming annual maintenance costs by 60%.
  • Technological Breakthrough: Mortise-and-tenon joints and 140° conical holes reduce clogging by 90%.
  • Energy Savings: Per-ton coal dewatering energy use fell by 15 kWh, while equipment failure rates dropped by 27%.

After 18 months of R&D and 5,000 fatigue tests, this product lasts 1.5 times longer than traditional PU panels in 80°C environments. The China Coal Processing and Utilization Association estimates nationwide adoption could save over ¥450 million annually in electricity, supporting the coal washing industry’s green 转型.

Technical Pain Points Solved: Three Fixes for Wet Material Screening Challenges

Traditional metal dewatering screens suffer from three critical flaws:

 

  • Frequent Clogging: Material jams in seams cause 3–4 daily shutdowns.
  • Inefficient Maintenance: Localized wear forces full replacements, costing over ¥120,000 yearly.
  • Poor Dehydration: Coal slime sticks to metal, leaving product moisture as high as 18%.

HUATAO’s Innovative Modular PU Screen Solution

  • Tongue-and-Groove Quick-Connect: Module gaps <0.3mm plus 140° conical holes reduce clogging by 90%.
  • Independent Unit Design: Replace only damaged sections, cutting consumable costs by 60%.
  • Micro-Textured Surface: PU’s 40% lower tensile strength than metal triples coal slurry shedding rate.

 

Test results: Post-dewatering coal moisture dropped from 18% to 13%—setting an industry benchmark.

From Lab to Large-Scale: Production Line Efficiency Gains

Comparison data from a Brazilian coal washing plant under identical conditions:

 

Indicator Traditional Metal Screens Spliced PU Screens Change
Daily Effective Runtime 16 hours 18 hours +12.5%
Energy Use per Ton 100 kWh 85 kWh -15%
Replacement Time 4 hours 1.5 hours -62.5%
Vibration Motor Failure Rate 11.3% 8.2% -27%

 

“Cutting screen weight by 50% directly reduces equipment load, slashing failure rates,” notes Wang Wei, Factory Technical Director.

Ultra-Durable Design: Redefining Lifespan Standards

  • Extreme Environment Tested: 12-month lifespan in 80°C hot water circulation.
  • Fatigue-Proven: Passed 5,000 mechanical impact tests (ISO 9001-certified lab).
  • Patented: 3 utility model patents; 1 invention patent under review.

 

National energy savings potential: With coal washing/dewatering consuming 3 billion kWh yearly, modular tech could save ¥450 million in annual electricity costs.

 

Applications Beyond Coal: Validated for mine tailings dewatering and municipal sludge treatment.

 

Policy Alignment: Environmental zero-emission rules are accelerating metal screen replacement.

Technical Trend: Modular Design Drives Smart, Green Upgrades

Modular technology is pushing coal washing equipment toward “modular assembly + intelligent maintenance,” unlocking new carbon reduction pathways.
