Performance enhancement tools for grinding mills

PERFORMANCE ENHANCMENT TOOLS FOR GRINDING MILLS 109 uncertainty may be very misleading for the operator. It is possible that a load composed largely of balls may be interpreted as a ‘very hard ore’ condition, due to the lower tonnage and higher power consumption observed. Also, in spite of efforts to keep the ball level at a constant value, ball breakage or changes in the mineral feed may
