Abstract
An agitator ball mill for processing free-flowing products features a horizontally split housing (2a, 2b) as a grinding bin in which a disc-shaped agitator (1) is arranged to rotate. The product enters the grinding product inlet (17) and flows through an upper disc-shaped grinding chamber (8a), an outside deflection zone (10), and a lower disc-shaped grinding chamber (8b). At the lower grinding chamber (8b), a deflection zone (11) arranged radially to the inside is connected in which the product containing the grinding pearls is deflected to the upper grinding chamber (8a). In the area between the deflection zone (11) and the upper grinding chamber (8a), a branch channel (13) branches off radially to the inside to the separation zone (14), along which a partial stream of product flows to this separation zone (14) whereas a second partial product stream together with the grinding pearls enters the upper grinding chamber (8a).
