Midwestern Industries Introduces the MR-7 Double-Deck Screener; Features End-tensioned Screen Panels for Efficient Material Discharge

Massillon, Ohio – The new Model MR-7 Screener with its compact, highly-efficient design is specially engineered for conveyor-type installations.  The double-deck MR-7 from Midwestern Industries allows materials to be separated from an approximately 1” opening on the top deck to a separation down to 1/8” opening on the bottom screening deck.

This 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. The MR-7 Screener (48” W x 84” L) comes complete with 2 HP, 230/460-volt, 3-Phase, 60-cycle, 1750-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 unique 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 utilized to full capacity, virtually ensuring the elimination of dead areas. The end-tensioned screen panels are easily changed for screening without costly downtime.

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 utilizes 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 retro-fitted 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 surface tension is broken and the damp material is unable to stick to the wire mesh, thus maintaining 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. 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.

Midwestern is a U.S. screening equipment manufacturer and weaves wire cloth for most makes and models including both end-tensioned and side-tensioned screeners. Custom woven screens are created specific to applications and designed to maximize screening efficiency.
