Abstract (en)
[origin: US5967430A] PCT No. PCT/DE96/01695 Sec. 371 Date Mar. 9, 1998 Sec. 102(e) Date Mar. 9, 1998 PCT Filed Sep. 5, 1996 PCT Pub. No. WO97/09115 PCT Pub. Date Mar. 13, 1997In order to reduce the conversion and cleaning effort between pre-dispersion by a dissolver (2) and fine dispersion by an agitating ball mill (3), it is proposed to combine both devices in a single container. The casing (31) of the agitating ball mill (3) is in the form of a toroidal annular channel with a central hole (34). The drive shaft (21) of the dissolver (2) runs through said central hole (34) in the agitating ball mill (3). Dispersion may take place in the dispersing device simultaneously or in succession. The agitating ball mill (3) is preferably lowered inside the container (1) along the common axis after a pre-determined time and caused to act on the substance to be dispersed (5).
