Flip-flow screens, also known as flip flop or elastic mesh screens, are machines designed to efficiently screen sticky, wet, and other difficult materials. Flip-flow screens are used in a number of industries to separate everything from aggregate and minerals to inhomogeneous recyclables, construction waste, and biomass.
Because of their unique design they provide operators a number of benefits. We’ll highlight additional details about flip flop screen design, usage, and benefits below.
Vibrating flip-flow screens are increasingly employed in materials screening and preparation applications. This is due in large part to their high efficiency. In principle, a flip-flow screen is a subclass of other high frequency vibratory screens.
Flip-flow screens work through the combination of a double vibration principle and a flexible polyurethane-type screen media. The dual-vibratory forces work to apply linear acceleration to the materials traveling across the screen. Vibrations are simultaneously applied to the elastic screen, which rapidly stretches and relaxes. The stretching and relaxing of the screen transfers energy to the material, causing it to “jump” or “pop”. This secondary vibration, in turn, enhances the separation of materials.
You can find this screening equipment used across a large number of industries. They’re most often used to screen difficult materials used in the manufacturing process for everything from sand, concrete, and compost. However, flip flop screens are also used in municipal solid waste processing.
