Flip-Flow Screen
-
Absolute Anti-Blinding Performance: Alternating tensioning and relaxation mechanics throw material upward with high dynamic forces, completely eliminating mesh clogging and particle pegging.
-
Handles Extreme Moisture: Engineered to dry-screen sticky, damp, or clay-laden materials with high water content that cause traditional rigid screens to instantly fail.
-
Ultra-High Local Acceleration: Delivers intense trampoline-like acceleration forces of up to 30g to 50g directly to the flexible mats, while keeping main structural frame stresses exceptionally low.
-
Efficient Fine-Particle Classification: The premier industrial choice for challenging, near-size fine separation down to 1 mm – 10 mm without requiring water-wash assistance.
1. Product Overview
The Flip-Flow Screen (commonly known as a relaxation screen or elastic mat vibratory separator) is a cutting-edge, high-velocity screening solution engineered specifically for processing difficult, sticky, wet, or ultra-fine bulk solids. Widely utilized in coal preparation plants, damp iron ore screening, municipal solid waste (MSW) recycling, compost sorting, and aggregate fine classification, this equipment breaks through traditional screening bottlenecks. By applying a continuous stretching and relaxing action to specialized flexible polyurethane panels, it fluidizes the material bed to deliver massive processing capacities and unmatched grading efficiency under the most punishing conditions.
2. Detailed Description
As shown in the structural design framework (image_247ad9.png), this equipment utilizes a specialized dual-frame design consisting of a primary rigid vibrating body and a secondary floating counter-frame connected by high-durability rubber shear blocks. As the eccentric drive shaft rotates, the relative movement alternately stretches and slackens the sloped polyurethane screen mats. This movement creates an intense trampoline effect, generating kinetic forces up to 50g directly on the panels to break the natural cohesion of sticky material mounds. The modular, boltless wedge-locking panel configuration enables rapid mat replacements, while the fully enclosed dust-tight steel shell configuration completely suppresses atmospheric emissions, satisfying modern green factory environmental mandates.
3. Why Choose Us
-
Elimination of Expensive Wet Screening: Cleanly dry-separates damp, clay-rich materials, completely eliminating the need for high-cost downstream slurry settling ponds or dewatering circuits.
-
Structural Foundation Safeguarding: The sub-resonant dual-frame setup counterbalances dynamic forces internally, reducing vibration transmission to the plant foundation or supporting building steelwork by up to 90%.
-
Superior Mechanical Lifecycle: Premium composite polyurethane mats offer maximum resistance to severe mineral abrasive wear and chemical corrosion, drastically lowering annual replacement expenditures.
