Process Diagram - an overview | ScienceDirect Topics

Process diagrams, called "flow diagrams" by TOGAF, are used to model the sequence of activities within a process. Process modeling formalizes practices and describes the manner in which they should take place. Flow diagrams represent process participants, activity sequences, information exchanged during a process, and trigger events.

Rawmill - Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
