The mixing apparatus comprises a mixing container with vertical axis which mixing container comprises an interior space and an outer annular space, communicated with the interior space by an annular gap. Within the interior space, there is performed a size reduction of the material to be mixed into granulated material which enters the outer annular space through the annular gap. The annular gap has comb-like openings so that only parts of small size are allowed to pass through.
