We will begin with the mill’s bull gear assembly and work towards the motor The BULL GEAR sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill By mill we refer to Ball Mills Rod Mills and SAG Mills Anything gear and pinion really The discharge end of the mill For the operator this only becomes a problem should the
Motor Start Time to start mill 6 to 10 seconds Standard Torque Motor Start Clutch Engagement 250 175 100 0 Time Amperage Uncomplicated design Air actuation and the absence of linkages splines or complex electrical circuitry needed with other types of clutches eliminates many mechanical failures and minimizes costly downtime Air is only used
Therefore the large ball mill usually uses air clutch to assist startup During the startup process the motor is started up to the rated speed Then the ball mill is started through the engagement of the clutch This study focuses on the dynamic behaviours of
Selecting Inching Drives for Mill and Kiln Applications Glen Cahala Frank C Uherek Principal Engineer Gear Engineering Software Development Abstract The inching drive also known as a barring or auxiliary drive is an important component of any mill or kiln installation It
