Speaker:  Dean David, Senior Consultant, Wood

Abstract:  Definitive closed circuit pilot tests, carried out a decade apart on the same sample of Southdown magnetite ore, revealed Vertical Roller Milling (VRM) to ~85 µm P80 to require only 60% of the power of a well operated SABC circuit. VRM is a technology sitting where SAG milling was in the 1980s. Wood now recommends to clients that VRM is included in our comminution tradeoff studies for projects suited to SAG and HPGR circuits.

Bio:  Dean David was with JKTech for 8 years from 1996 to 2003 and was Manager of consulting for the last half of that time.
