Conexpo-Con/Agg 2020: MAJOR to showcase Flex-Mat screening solution

Flex-Mat screen media panels

Company using show to highlight its flagship high-vibration wire screen media

MAJOR, a leading global manufacturer of high-performance screen media, will be using this year’s Conexpo-Con/Agg to present their Flex-Mat high-vibration wire screens. The company’s technologically advanced wire screen media has been designed to deliver increased throughput by providing more open area than traditional panels.

According to MAJOR, Flex-Mat offers customers greater operational benefits with up to 40% more screen capacity than traditional woven wire and up to 50% more than traditional polyurethane/rubber panels, setting a new standard in performance for aggregates and mining producers. 

The innovative product’s high frequency movement helps make the media an active part of the screening process, improving efficiency compared with static media such as woven cloth and synthetic panels.

‘Quality is key to any operation, which is why we place a strong emphasis on it at MAJOR,’ said Bernard Betts, president of MAJOR. ‘We understand that no two operations are identical, which is why we configure each screening panel to precisely fit individualized requirements. That attention to detail is how we achieve what alternative media cannot — unrivalled throughput and superior end-product quality.’

The efficiency-enhancing characteristics of all Flex-Mat screening media products, including the modular panels, are created by bonding OptimumWire — the industry’s longest-lasting wire — with distinctive lime-green polyurethane strips rather than weaving them.

This allows wires to vibrate independently from end to end under material contact. The high frequency of the wires, at 8,000 to 10,000 cycles per minute, adds to the vibration of the screen box (800–900 cycles per minute) which speeds up material separation and passing.

MAJOR say these features improve material throughput while virtually eliminating near-size pegging on the top decks and fine material blinding and clogging on the bottom decks, reducing the overall cost of production. The company added the screen media provides up to five times longer wear life than traditional woven wire.

The Flex-Mat modular panels are available in three pattern options – D, S, and T series. The D series feature a standard square pattern for precise sizing, while the S series maximize an open area to eliminate blinding and reduce fine contamination.

The T series enhance screening for particles below 0.059 inches (1.5mm) and feature small openings to minimize blinding. The wire screen is secured through either grooved, step, or pin and leg panels.

MAJOR’s flagship Flex-Mat screen media panels are offered in either the patented OptimumWire or 304 stainless steel wire. They are also available in tensioned sections for use on crown decks.
