How to Choose the Optimal Screen Panel Thickness for Your Ore Type

Choosing the right screen panel thickness isn't about finding a single "magic number." It's about balancing durability against screening efficiency—and the optimal thickness varies significantly based on your ore type, feed conditions, and operational priorities.

Here's a practical framework to guide your decision.

The Core Trade-Off: Durability vs. Throughput

Thickness Selection Guide by Ore Type

By Panel Type:

Key Operating Factors

1. Feed Drop Height
If drop height exceeds 1 meter, use thicker panels or impact pads. For extreme impact, panels should be 50mm+.

2. Aperture-to-Thickness Ratio
Aperture size should be 1.25–2.5× (rubber) or 1.25–3.5× (polyurethane) of thickness.

3. Hardness (Shore A)

• Softer (60–70): Better anti-blinding for wet/sticky materials

• Harder (85–95): Superior abrasion resistance

Decision Flowchart

Start
  │
  ├─ High impact (drop >1m) → THICK (≥50mm)
  ├─ Low impact → MEDIUM-THIN (≤35mm)
  │
  ├─ High abrasion → THICK + HIGH HARDNESS (85 Shore A+)
  ├─ Low abrasion → MEDIUM-THIN (≤30mm)
  │
  └─ Verify aperture-to-thickness ratio

Real-World Case Studies

Case 1: Australian Iron Ore

• Feed: 300mm, 3m drop height

• Solution: 50–100mm panels

• Result: Service life doubled (12→24+ weeks)

Case 2: Gold Mine Dewatering

• Feed: Gold ore, medium impact

• Solution: 30mm rubber panels

• Features: Anti-blinding, 120°C tolerance

Case 3: Fine Wet Screening

• Feed: Wet screening, <3mm

• Solution: 2.5–5.5mm PU mats

• Features: High open area, anti-blinding
