The new Model MR-7 Screener with its compact, highly efficient design is specially engineered for conveyor-type installations. The double-deck MR-7 allows materials to be separated from an approximately 1-in. opening on the top deck to a separation down to 1/8-in. 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, and many other industrial-type materials. The MR-7 Screener (48-in. wide x 84-in. long) 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,” said Chip Painter, VP 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 reuse 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 can be retrofitted with the Midwestern Converta-Screen Heating transformer to eliminate blinding. By applying a low-voltage current through the screen mesh, the surface tension is broken and 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.
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.
