Abstract. A 200-300% increase in grinding component wear life and significant reductions in unplanned outages and load reductions have been realized when MBF pulverizers are installed at coal-fired utility plants. The larger rollers permit the MBF pulverizers to accommodate large feeds and impurities without distress or component damage.
