High-Elasticity Rubber Screen Panels Solve Wet Material Clogging for Brazilian Aggregate Producer
High-Elasticity Rubber Screen Panels Solve Wet Material Clogging for Brazilian Aggregate Producer
Background: Persistent Blockage Crisis in Tropical Climates
A building materials manufacturer in Minas Gerais, Brazil, faced severe screen clogging from wet materials due to year-round rainfall exceeding 1,800 mm annually. Previous attempts with stainless steel and polyurethane screens failed: stainless steel screens clogged every 30 minutes, while polyurethane screens hardened and lost elasticity after 6 weeks, resulting in 40% blockage rates. Monthly losses amounted to approximately $12,000.
Solution: 40 Shore A High-Resilience Rubber Screen Panels
Following on-site assessment of material moisture (18–22%) and screening machine parameters, four rows of custom 40 Shore A rubber screen plates were recommended:
- Ultra-high resilience enables “self-cleaning” during vibration;
- Wear-resistant formulation withstands granite abrasion;
- Trapezoidal aperture design minimizes material entrapment.
Trial Results: Near-Zero Blockage, Enhanced Efficiency
30-day trial demonstrated significant improvements:
Blockage rate reduced to under 1% (from 40%);
Eliminated manual cleaning, saving 3–4 hours daily;
Daily output increased by 18% to 1,000 tons.
Three-month follow-up: Durability exceeded expectations
Screen surface showed no wear or deformation, zero clogging downtime, accumulating savings over $36,000 USD. Customer placed additional orders and signed an annual maintenance agreement.
Key insights for rainy regions
Elasticity is the core solution for wet clogging. Customize screen mesh material and aperture design to balance elasticity and wear resistance. Select suppliers offering on-site evaluations.
