By pre-screening the feed, users can maximize their scalping ability and minimize the amount of undersized material passing through the chamber, reducing wear costs and increasing the amount of final product by 30 percent.

Kolberg-Pioneer has added a two-deck, 4 by 7 ft. pre-screen option to its FT4250 mobile impactor plant. The new option allows producers to scalp the feed, crush the material and post-screen all on one unit.

By pre-screening the feed, users can maximize their scalping ability and minimize the amount of undersized material passing through the chamber, reducing wear costs and increasing the amount of final product by 30 percent.

"Several of our customers are trying to produce products that have a significant amount of fines in the feed material. The pre-screen allows producers to remove those fines while also minimizing the amount of rejected in-spec product," Tim Harms, crushing and screening product manager at Kolberg-Pioneer, said.
