Flip Flows
Why Graepels Flip Flow Screens?
Flip flow screens and polyurethane screens are lighter and thinner, and more flexible than rubber screens. They can be successfully punched in various perforated shapes with smaller apertures and work well where plugging is an issue.
Flip flows are used to screen difficult material which when wet tends to stick. Our flip flow/flip screens rival that of industry names such as spalek and binder. Providing you with high-performance, high-quality screens that offer maximum performance, giving you screens that offer the cleanest screening results in addition to lower operating costs as the screens provide efficient throughput and material flow.

Graepels Polyurethane Screens offer superior screening efficiency even in the most demanding of applications, and are particularly effective when screening wood chips, building rubble, soil, and plastic. Graepels Flip Flow screens offer a high, wear-resistant tolerance. The screens can be quickly and easily replaced due to their method of installation.
A variety of lengths and widths can can be manufactured to suit all makes of screening machines including Binder, Finlay Spaleck, CRS, Powerscreen Spaleck, Kiverco, Edge, IFE and Triso. Round, square, slotted and hexagonal aperture shapes are available.

Custom Manufacturing: Screens can be manufactured by Graepels to suit all makes of machinery within the quarrying, waste management and recycling industries
Cost Effective: Low operating and maintenance costs
Material Composition:
Polyurethane Screens: Polyurethane screens are made from polyurethane material, which is a synthetic polymer known for its flexibility, durability, and resistance to abrasion, corrosion, and chemicals.
Flip Flow Screens: Flip flow screens are typically constructed with elastic mesh mats and molded polyurethane crossbars. The screen deck may also incorporate perforated plates or woven wire mesh.
Screening Principle:
Polyurethane Screens: Polyurethane screens use traditional screening principles, where particles are separated based on size as they pass through the openings in the screen surface. These screens can be flat or curved and may have various opening shapes and configurations.
Flip Flow Screens: Flip flow screens employ flip flow technology, where the screen deck oscillates or flips to impart vibrational energy to the screen surface. This motion prevents blinding or clogging of the screen and facilitates efficient screening of difficult-to-screen materials.
Screening Efficiency:
Polyurethane Screens: Polyurethane screens offer high screening efficiency and are suitable for
a wide range of applications. They provide effective particle separation and are resistant to wear and tear.
Flip Flow Screens: Flip flow screens offer superior screening efficiency, particularly for challenging materials such as wet, sticky, or fine particles. The flip flow motion prevents material buildup on the screen surface and ensures consistent screening performance.
Maintenance Requirements:
Polyurethane Screens: Polyurethane screens require minimal maintenance and are easy to clean. They are resistant to blinding and clogging, resulting in lower maintenance requirements.
Flip Flow Screens: Flip flow screens also have minimal maintenance requirements due to their self-cleaning action and resistance to blinding. They are designed to operate continuously with minimal downtime.
