Is this a multiple stage gearbox and do we know (for sure) is it a planetary arrangement (as opposed to a sun or solar arrangement).

There are two stages of this gearbox; first is simple gearbox with bevel gear and is driven by motor. Output shaft of this gearbox run at 40rpm which drives the sun of second stage of gearbox which is a planetary (epicyclic) gearbox. Carrier of this gearbox drives the table of Raw Mill.
