- the stirring blades 14c in particular - -
- FIG. 9 shows an exemplary POX autoclave 50 with a horizontally arranged container 64 and a plurality of agitators 44 arranged in the container 64.
- the agitators 44 each comprise a drive unit 46, a stirring shaft 48 and an agitator device 10a, 10b, 10c which can be driven by means of the stirring shaft 48 ,
- the container 64 is divided in the present case by partitions 66 into four container areas.
- the agitators 44 are identical in the present case.
- the agitators 44 are arranged in the container 64 such that the respective axis of rotation 20 is arranged perpendicular to a horizontally arranged container axis.
- the system comprises five agitators 44.
- abrasive medium in the container 64.
- the abrasive medium is formed in the present case as a suspension with a high solids loading.
- the POX autoclave 50 has, for example, two gassing lances 68, which are arranged in the first container region 70.
- the gassing lances 68 are provided to supply oxygen to the abrasive medium in the first container region 70.
