Grinding system for grinding a material to be ground, and method for grinding a material to be ground

A grinding installation for comminuting material, the grinding installation comprising:

• a grinding apparatus;
• a classifying device that is connected to the grinding apparatus and classifies the material, the classifying device comprising:
• a static classifier,
• a dynamic classifier, wherein the static classifier is disposed so as to at least partially surround the dynamic classifier,
• a course material outlet for discharging course material that comprises a coarse grain fraction,
• a grit outlet for discharging grit that comprises a medium grain fraction, and
• a finished material outlet for discharging finished material that comprises a fine grain fraction;
• and
• an open-loop/closed-loop control device for open-loop/closed-loop control of at least a part of a stream of the material to the grinding apparatus.

A method for comminuting material, the method comprising:

• comminuting the material in a grinding apparatus;
• classifying the material in a classifying device into coarse material, grit, and finished material, wherein the classifying device comprises a static classifier that is disposed so as to at least partially surround a dynamic classifier;
• and
• controlling at least a part of a stream of the material to the grinding apparatus in open-loop/closed-loop fashion by an open-loop/closed-loop control device.
