Braking the Worlds Largest Ball Mills
In static operation the braking system is used to hold the mill during liner replacement and general mill maintenance. For dynamic operation the system can operate in two modes, stopping the mill from full speed in an emergency, or giving inching/creeping operations in the event of bearing lubrication problems or power failures.
