Powders and compounds with a tendency to form lumps are continuously incorporated inLine and effectively dispersed. This means that even in a single pass, very high concentrations can be achieved. The first stage in the reactor head creates a strong negative pressure and sucks the solids phase in. Immediately after contact with the liquid phase, this premix of the 2 phases is impelled against the XC impact chamber plates where the liquid is absorbed into the powder phase. The second stage discharges the homogeneously wetted product.
