Abstract
An apparatus and a method for dosing and mixing solids and liquids to form a low viscosity suspension comprises at least one continuously operating mixing device and a supply device for supplying the components to the mixing device, in order to obtain a desired initial pressure. The supply device is constructed as a drag flow pump (1) which is connected to the mixing device (6) by a pressure pipe (13), at least one solids and liquid introduction device (15, 16 or 17, 18) is provided along the drag flow pump (1) and the latter is followed by at least one liquid introduction device (27), a shut-off device being provided in the pressure pipe (13).
