Higher Wear Resistance Polyurethane Flip Flow Screen Media for Mining

Polyurethane Flip Flow Screen Normal Specification

Red Star High Performance Polyurethane Flip Flow Screen Media for Mining

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.

though having a lower opening screening area than wire screens, especially on smaller apertures, flip flow screens and mats, offer the advantage of a much longer lifespan and reduced noise levels. Manufactured from high wear resistant materials these screen mats are ideal as complete decks on larger screen boxes or as an impact section prior to a wire screen.

1.Polyurethane Flip Flow Screen: square hole, long hole.

2.RedStar has more than 10 different types of Polyurethane Flip Flow Screen for customers to choose,

3.RedStar can also be customized to customer requirements of other sizes of Polyurethane Flip Flow Screen.

Polyurethane Flip Flow Screen 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:

1.High acceleration up to 50g in the screening mats

2.Loosening-up of the product

Polyurethane Flip Flow Screen Features

1, flip flow screens using the best quality raw materials production, product-specific high wear resistance. Long service life.

2, flip flow screen has excellent toughness, stronger than the average polyurethane mesh toughness.

3, Polyurethane Flip Flow Screen using a mold casting molding, a variety of holes can be processed.

4, Polyurethane Flip Flow Screen thickness is generally 4-8mm, lightweight, sieve machine load is small.

5, polyurethane relaxation screen in a short time to produce a considerable high frequency of expansion and contraction, and to achieve the purpose of screening materials. In such a high frequency of movement, the material is difficult to pile up the phenomenon.

6, Polyurethane Flip Flow Screen hole rate is extremely high, the processing capacity per unit area, high screening efficiency.

Polyurethane Flip Flow Screen Features Application

Polyurethane Flip Flow Screen is widely used for the classification of bulk material, such as coal, minerals, coke, beans, etc. So it can be used in the agriculture, chemical industry, minerals, quarry and smelting industries.

Polyurethane vibrating screen can sort the wet materials, it can be used in the water conservancy and hydropower and dewatering industries.

Efficient screening of difficult, sticky or wet materials with separation cuts of 0.2 to approx. 50 mm.

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 screener, 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.
