Midwestern Industries Double-Deck Screener Offers Flexibility

The new Model MR-7 Screener with its compact, highly efficient design is specially engineered for conveyor-type installations. The double-deck screener 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, slag 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, 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.

Additionally, the MR-7 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 surface tension is broken and the damp material is unable to stick to the wire mesh, thus maintaining higher production rates.
