Mine-duty screen

Deister Machine Co., Inc., plans to launch its new BFO-11224-EX2 mine-duty screen at ConExpo-Con/Agg 2014. The 12- x 24-ft (3.7- x 7.3-m) horizontal, single-deck unit delivers reliability and high-volume capacities in a variety of hard rock mining and mineral processing applications, the company claims.

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.
