Deister’s New Screen Delivers Day-to-Day Reliability


Deister’s New Screen Delivers Day-to-Day ReliabilityContinuing its commitment to ongoing innovation, Deister Machine Co. Inc. launched its new BFO-11224-EX2 Mine-Duty Screen at this year’s ConExpo-Con/Agg. Offering the next generation in machine size and production output, the 12- x 24-ft., horizontal, single-deck unit delivers day-to-day reliability and high-volume capacities in a variety of hard rock mining and mineral processing applications.

The BFO-11224 features the new Deister EX Series of geared exciters, which are designed to create the force output required to drive today’s large screens. Geared exciters feature all-steel components; specially-coated bearing inner races to deter wear on shafts; and shafts that are case-hardened and ground for minimal wear. Mechanisms are sealed to minimize oil contaminants and maximize bearing life. Seals ride on replaceable ceramic coated spacers that minimize heat and increase seal life up to 10 times that of conventional steel spacers and seals, according to the company.

To meet the most stringent structural specifications, the BFO-11224-EX2 features fully-bolted construction and A572-Grade 50 steel. For ease of maintenance, the unit is engineered with independent cross beams.

The Deister Mine-Duty Horizontal BFO Model Screen Series range from 3- x 4-ft., and up to 12- x 28-ft. units; and deck configurations from a single deck up to four decks. Models are either eccentric shaft driven or geared exciter driven. Deister has the ability to customize a screen to suit exacting requirements such as existing foot prints, restricted overhead space, high-volume processing, and more.
