How mass flow and rotational speed affect fertiliser centrifugal spreading: Potential interpretation in terms of the amount of fertiliser per vane

The influence of the mass flow and the disc rotational speed on the outlet angle and the angular distribution of the fertiliser mass flow around a disc for two fertilisers are examined. The width of the angular mass flow distribution changed as a function of the amount of fertiliser per vane whatever the origin of its modification (i.e. rotational speed or mass flow).

► Effects of the mass flow and the rotational speed were analysed and compared.
► Outlet angle is not a function of the fertiliser amount per vane.
► Angular location of the spreading distribution is not a function of the fertiliser amount per vane.
► Width of the spreading distribution is a function of the fertiliser amount per vane.
