Method of observing a change of mass inside a grinding unit

摘要

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.

主权项

1. 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.
