Grinding Mill Controlclevenstineengineering

Grinding Mill Control The primary grinding stage at a taconite plant on Minnesota’s Mesabi Range consists of ten wet grinding mills, each 26’ in diameter and 16’ long. Each mill is driven by two 3,500 hp wound rotor induction motors. Maximum production through each mill is limited by the ratings of the induction drive motors. The power draw for the motors is controlled by adjusting the,
