Flip flop or flip flow screening machines have been in operation for decades for screening of moist or humid materials. Some typical applications
Iron Ore at 6mm with 15% moisture
Raw sand at 3mm with 6% moisture
Compost at 10mm with 50% moisture
Slag at 3mm with 10% moisture
Salt at 3 mm with 5 % moisture
Coke at 3mm with 20% moisture
Lignite at 6mm with 50% moisture
Coal at 6mm with 18% moisture
Limestone at 3mm with 20% moisture
Pet coke at 3mm with 18% moisture
Plus other hard to screen materials like wood chips, bamboo chips, washery waste, building rubble, soil, plastic, auto parts etc.
Principle of Operation :
Generally referred to as flip flow or flip flop screening method. During the cycling of screen, the flexible mats are individually tensioned and relaxed, which breaks or loosens the adhesive bond within the materials, and between the material and flip flow screen mats.
In the upstroke, the material is impelled upward functioning like a trampoline and air is drawn in and through the material. The motion is such that the acceleration on machine support frame could be approx 3g whereas the material on the screen panels may experience around 50g.
During these stretch & relax moments, the openings or aperture in the screen mats get elongated , stretched or bend which tremendously helps in release of particles which might have got jammed.
Orithane Spare Screens/Mats for all machines :
Orithane produces widest range of flip flow / flip flop / Feed Impact / screen mats ready for installation on machines of all types, sizes and manufacturers.The screen sieve mats are made from proprietary grades of highly resilient Elastomers (including polyurethane / PU) with balanced range of properties to withstand deformation without loss of elasticity or dimensional accuracy.
Only high quality elastomers are used to guarantee highest performance in terms of abrasion resistance, cut & tear resistance, flexibility and resilience.
All apertures shapes like
Square apertures - linear pattern & crossed pattern
Slot apertures linear pattern & crossed pattern
Round apertures linear pattern a& crossed pattern
Both Bolted & Clamped types design fitment options are available.
