PURPOSE: To obtain the method, whereby both mixing and stirring work can be simultaneously performed automatically without using a mixing means further with the material successively conveyable at a proportion of constant amount, when conveyed more than two kinds of plural materials.
CONSTITUTION: Now when the prescribed amount of granular material, fed by a hopper H1 onto a flight conveyer 1, comes to a position below a hopper H2, a different kind of next material is fed by the hopper H2. Thus with the material successively fed by the hopper H1WH3 so to be piled up on the flight conveyer 1, while being transferred by a flight 1b on a trough, the piled up layer of material is destroyed with a rough mixing operated. Subsequently, with the material dropped down from an outlet hole 1a onto a second stage flight conveyer 2, at this drop down moment, each kind of the material is stirred and mixed with each other. And when transferred by a flight 2b on said conveyer 2, with a rough mixing further performed, and thereafter successively with the above described same process repeated, the material is mixed and conveyed.
