While MDI-based materials are the mainstay for heavy mining, TDI based polyurethane screen panels fill a critical niche in agricultural applications and cold-climate operations. TDI elastomers are characterized by their outstanding elasticity and exceptional low-temperature flexibility, remaining fully functional at temperatures as low as -40°C. This makes them the ideal choice for outdoor screening tasks in northern regions, such as processing ice-snow mixtures or agricultural products during winter months.

• Manufactured from highly resilient polyurethane elastomer
• Flip flow mats with joints maintain elasticity and dimensional accuracy
• Designed for both bolting and clamping systems
• Compatible with all screen decks worldwide regardless of machine brand
• Universal fit for various deck dimensions and installation characteristics

RFQ

Q: What essential material information must I provide when submitting a Flip Flow Screen RFQ?

A: To ensure accurate equipment selection and sizing, the following data is required:

1. Material Name (e.g., Coal, Iron Ore, Municipal Waste, or Compost).

2. Maximum Feed Dimension and approximate feed size analysis.

3. External Moisture Content (%) and whether the material is sticky or fibrous.

4. Bulk Density of the material.

5. Required Separation Sizes (cut points).

6. Desired Processing Capacity in tons per hour (t/h).

Q: Why is a Flip Flow Screen superior to a Linear Vibrating Screen for damp or sticky materials?

A: Standard linear screens often fail due to "blinding," where moisture creates a film that covers screen holes. Flip Flow screens use a dual-mass vibration principle to alternately stretch and relax elastic polyurethane mats. This motion creates a 50g projectile acceleration that breaks the adhesive bonds of moisture films and dislodges near-size particles, fundamentally preventing clogging.

Q: How do I choose between MDI and TDI polyurethane for my screening mats?

A: Selection depends on your specific application and environment:

• Prioritize MDI for high-wear, high-impact tasks (e.g., iron ore, aggregates) or operations in harsh chemical (acidic/alkaline) and wet environments. MDI offers superior durability and a service life 1.5 to 3 times longer than TDI.
• Consider TDI if you need high elasticity to protect fragile or brittle materials (e.g., agricultural grains) or if operating in extreme cold down to -40°C.

Q: What is the maintenance intensity for these screen mats, and is the replacement process difficult?

A: Polyurethane mats are designed for low maintenance due to their self-cleaning properties. Modern designs utilize boltless fastening systems (such as snap-fit interference wedges or PU connectors), which create an absolutely smooth surface to prevent material buildup. These systems allow for very rapid replacement, enabling one operator to change ten square meters of screen surface in just one working hour

Q: Why Flip Flow instead of Linear Screens?

A: Flip Flow screens generate 50g acceleration which breaks surface tension and breaks up caked material, preventing blinding and pegging in materials with up to 50% moisture.

Q: MDI vs. TDI: Which should I choose?

A: Use MDI for heavy-duty, high-wear mining (ores/aggregates) as it lasts 1.5–3x longer. Use TDI for agriculture or extreme cold (down to -40°C) where flexibility is priority.

Q: How long does it take to replace screen mats?

A: Using boltless fastening systems, a single operator can replace 10 square meters of screen surface in just one hour.

Q: Can I customize the aperture shape?

A: Yes. Options include square, round, oblong, and specialized boomerang or peanut shapes designed to eject wedged particles
