For the processing of coal and charcoal at the new CST coal-powder injection system for the nr. 3 blast furnace currently under construction, Arcelor has purchased from Mavi a set of three heavy construction Vibrapen screeners.

Two of them types 1220 x 2900 mm are for the proctective screening of coal powder before injected in the blast furnace itself, in order to remove larger particles which could clog the injection nozzles.

Another one is a raw material 1400 x 4000 mm Vibrapen screener, fully vibration isolated and movable on a cart with wheels for easier maintenance.

Arcelor is the leader in coal powder injection technology for most Brazilian steel works and since 1974 recommends and installs Vibrapen screeners from Mavi for this purpose.
