Multi-Deck Flip Flow Screen System for Complex MSW and C&D
Grading
Product Overview
The multi-deck flip flow screen is a versatile solution designed
for the grading of complex waste streams such as municipal solid
waste (MSW) and construction and demolition (C&D) waste. The
equipment can be configured with up to four decks, allowing for the
production of multiple sized fractions from a single machine
footprint. Typically, a conventional upper deck acts as a
"protection deck" to remove large debris (up to 500mm), while the
lower decks utilize high-energy flip-flow polyurethane mats for the
fine sizing of difficult, inhomogeneous fractions.
Driven by a main shaft running at 700-1000 RPM, the system creates
a dual-mass vibration that generates a 25-30mm amplitude. This
intense movement is essential for waste recycling, as it prevents
thin films, plastic bags, and fibrous materials from blinding the
apertures. The polyurethane mats are acid- and
alkaline-insensitive, ensuring they do not degrade when exposed to
the varied chemical contaminants found in MSW. With a throughput
capacity up to 1000 t/h and a separation accuracy of 98%, this
multi-deck system represents a revolutionary technical path for
improving recovery rates and product quality in the global waste
management industry.

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
