Estimating the term…
A method is disclosed for controlling a mill system having at least one mill, e.g., an ore mill or cement mill, wherein electrical power is drawn from a power network to rotate at least one mill body for comminuting a material fed to the at least one mill body. One or more control variables of the mill system are regulated such that the power drawn from the power network corresponds to a predetermined setpoint power draw-off for the mill system. The method may provide control power in the power network for compensating for fluctuations in energy generation due to increased use of regenerative energies. The method may be used, e.g., to regulate high energy mill systems, e.g., tube mills, SAG mills, or ball mills, such that even relatively large quantities can be made available as control power in the power network.
A method for controlling a mill system having at least one ore mill or cement mill, wherein electrical power is drawn from a power supply network and supplied to the mill system to rotate at least one mill body to comminute a material fed to the at least one mill body, the method comprising:
