Abstract
An apparatus designed for the batchwise treatment of suspensions comprises a cylindrical reaction vessel (1) which is rotationally symmetric with respect to an axis (4) and within which, in a coaxial arrangement with respect to said axis (4), an insertion member (28') is disposed which includes a grinding cage (31) and the grinding bed formed by grinding balls (25). By means of delivery elements and stirring elements (35, 37) a suspension stream is generated which passes through the grinding bed in the direction of the arrows (28), leaves the insertion member (28') in the upper region thereof via radially oriented orifices (13) and is circulated via the annular chamber (15) of the reaction vessel (1). The reaction vessel (1) is of pressure-tight design, and heterogenous reactions can proceed inside it in vacuum or pressurized mode.
