MR-7 screener is engineered for conveyor applications.

CDR Staff February 4, 2014

Midwestern Industries, Massillon, Ohio, will introduce its MR-7 at ConExpo-Con/Agg in Las Vegas, March 4-8. The double-deck MR-7 screener with its compact, efficient design is engineered for conveyor-type installations. It designed to allow materials to be separated from an approximately 1-inch opening on the top deck to a separation down to a one-eighth-inch opening on the bottom screening deck.

The deck combination with end-tensioned panels provides a screening unit that can effectively handle sand, gravel, crushed stone, coal, slag, topsoil, mulch, ash, recycled asphalt or concrete and many other industrial-type materials, according to the company. The 48-inch wide by 84-inch long MR-7 screener comes complete with a 2-horsepower, 230/460-volt, three-phase, 60-cycle, 1,750 rpm motor, V-drive components, and belt guard and conveyor installation carriage members.

“The design of the MR-7 allows you to move the screener/conveyor combination to multiple job sites, thus giving a plant operator greater flexibility in handling different applications,” says Chip Painter, vice president of manufacturing for Midwestern Industries. “The MR-7 features high load capacity, high screening efficiency, quick set-up and low maintenance. It’s the ideal screening solution for a variety of industries that want to separate materials for re-use or obtain saleable products.”

One notable aspect of the MR-7 is the end-tensioned screen panels, which enable conveyed materials to move along the full-screen surface until discharge. The entire width of the MR-7 is used to full capacity, ensuring the elimination of dead areas. The end-tensioned screen panels are easily changed for screening without costly downtime, according to the company.

Crossbars support the end-tensioned screens and create a flat screening surface for the material to travel. Where most other makes of rectangular models have a crown that pushes the material outward, the MR-7 uses the entire screen deck, giving the screener the ability to handle the job of a larger screener in a more compact design. The end-tensioning panels are designed to fit both square opening and slotted screens.

The pedestal-mounted MR-7 Screen can be retrofitted with the Midwestern Converta-screen heating transformer to eliminate blinding because of damp material. By applying a low-voltage current through the screen mesh, the company says the surface tension is broken and the damp material is unable to stick to the wire mesh, which maintains higher production rates. The MR-7 can handle wash applications by applying easily adaptable spray bars.

The MR-7 is ideal for material screening in harsh conditions because the unit can be made from stainless steel or carbon steel with corrosion-resistant coatings, says Midwestern Industries. The MR-7 can be outfitted with a variety of screens, depending upon the application.

Midwestern Industries screens designed for the MR-7 are available in impact-resistant high carbon wire, abrasion resistant oil tempered wire or stainless steel. The company also offers its Interkleen screen, an elongated slotted screen designed to maximize throughput and reduce material plugging.

Midwestern has a free, full-scale test facility on-site to assist in determining the optimal configuration of the MR-7 Screen.
