First Claim
1. A roller mill comprising:
- a grinding plate;
at least two grinding rollers configured to interact with said grinding plate to comminute material to be ground;
at least two separate drive trains each having a main motor and a main gear mechanism, and each configured to drive the at least two grinding rollers or the grinding plate and one or more of the at least two grinding rollers, wherein at least a first drive train of said at least two separate drive trains further includesa superimposition gear mechanism,at least one regulating drive in communication with said superimposition gear mechanism, wherein the superimposition gear mechanism converts rotational movements of the main motor and the at least one regulating drive,an open-loop and closed-loop control device in communication with said at least one regulating drive, wherein the open-loop and closed-loop control device is configured by way of the at least one regulating drive to regulate power of said separate drive trains with respect to one another.
