Companhia Siderúrgica Nacional has recently (Feb. 2016) purchased new Vical-A feeders, with special linings for highly abrasive bulk solids to be discharged from large silos. Capacity is 500 t/h.
Vical-A feeders are of simple and extremely rugged execution. CSN has many of them running without replacement since 1974.
Driven by heavy duty Vimot electromechanical vibrators also from Mavi, the Vical-A feeders are almost a standard among Brazilian and Latin American steel works.
