A continuous mixing plant that, for example simply continuously feeds the necessary materials while metering the amount thereof and drops these materials by gravitational force so that the mixed material may be manufactured continuously. As a means for attaining this object, a continuous mixing plant comprising a continuous metering and feeding means for feeding at least two kinds of materials to be mixed with each other while continuously metering the materials, and at least one mixing box unit for mixing the materials, is characterized in that the mixing box unit is provided with: a plurality of modified passages each of which has an inlet at one end and an outlet at the other end and a cross-sectional shape of which is continuously changed from the inlet toward the outlet and which extend in an axial direction; and a merging and dividing means.
