Polyurethane Flip Flow Screen is mainly used for screening hard-to-screen materials, including sticky, fine and wet materials (such as highly sticky coal of high moisture content, and classification of medium & fine coke). The main advantages including high screening efficiency, long wearing life, wide application of particle size range, no pegging and no blinding. The flip flow screens are with high tensile strength, excellent wear performance, so as to achieve the designed service life of more than 4000 hours.
Efficient screening of difficult, sticky or wet materials with separation cuts of 0.2 to approx. 50 mm.
MODE OF OPERATION
The base frame is agitated by means of shaft and unbalance motor drive. The vibration is passed to the dynamic frame via thrust rubbers.Fixed screening mats between the dynamic and the base frame are clamped and ﬂ exed by the two vibrating frames. The modular and compact construction of the Red star Flip-Flow-Screen ensures a wide acceptance for many different applications. The easy assembly respectively changing of the screening mats, the extension to a multi-deck version and the dynamic stroke adaptation are further features. The vibrating cover can be opened without tools. This ensures a rapid and easy accessibility of the screening mats. The relative movement of both screening frames creates a "trampoline effect" for the screening mats. The advantages of this effect are:
· High acceleration up to 50g in the screening mats
· Loosening-up of the product
Non blinding screening mats – less contamination Compact and modular construction Single- or multi-deck execution Dynamic wear resistant screening mats allow an efﬁ cient material ﬂow – screwless mounted (fast changeover). The high acceleration on the screening mats ensures a self-cleaning effect.
