Kolberg-Pioneer, Inc (KPI) has added a two-deck, 4-ft x 7-ft pre-screen option to its FT4250 mobile impactor plant. This 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 maximise their scalping ability and minimise the amount of undersized material passing through the chamber, reducing wear costs and increasing the amount of final product by 30%.
“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 minimising the amount of rejected in-spec product,” said Tim Harms, crushing and screening product manager at Kolberg-Pioneer.
