Abstract
A system and method are disclosed for observing a change of mass inside a grinding unit as a part of a grinding process with a storing unit. The change of mass is derived from a mass balance for the grinding unit and a mass balance for the storing unit.
Claims10
A method for observing a change of mass inside a grinding unit as a part of a grinding process, the method comprising:
- determining a first mass flow (m1) of input material feed along a process input path to the grinding unit, the feed input material to be grinded by the grinding unit;
- determining a second mass flow (m5) of grinded material removed from a storage unit along a process output path, the storage unit storing grinded material from the grinding unit;
- determining a change of mass of the grinded material inside the storing unit;
- deriving a change of mass inside the grinding unit from the determined change of mass inside the storing unit and the determined first and second mass flows, and based on a previously established mass balance for the storing unit;
- and
- adjusting a grinding process operation based on the derived change of mass inside the grinding unit.

A system for observing a change of mass inside a grinding unit as a part of a grinding process, the system comprising:
- a storing unit structured to store output of the grinding unit;
- a first measuring device structured to measure a first mass flow into the grinding unit;
- a second measuring device structured to measure a second mass flow out of the storing unit;
- a third measuring device structured to measure a change of mass inside the storing unit;
- and
- a processing unit structured to derive a change of mass inside the grinding unit based on the determined change of mass inside the storing unit.
