A Brazilian iron ore producer has purchased six modular Niagara XL-Class banana vibrating screens for its iron ore processing plant. The 12- by 32-foot, exciter-driven vibrating screens were specifically designed to process 900 tonnes per hour of natural moisture content with a goal of classifying material below 19 mm.

The moisture content in green pellets with 0.5% bentonite was varied between 7.3% and 9.4%. By increasing the bentonite dosage up to 1.5%, the moisture range suitable for balling could be expanded up to 10.5%. Results from individual micro-balling batches are reported below.
