A device for the metering of fluidizable bulk materials, having a storage tank and a mass-flow-measuring device for the material and a fluidizing device, which is connected to the storage tank via an aperture of adjustable size, and a control valve for controlling the supply of compressed air to the fluidizing device, wherein a pressure gauge is provided downstream of the fluidizing device, in the direction of flow, and the pressure gauge and control valve are connected via a first control circuit, and the supply of compressed air to the fluidizing device is metered by this control circuit in such a manner that a constant, in each case preselectable subatmospheric pressure prevails in the fluidizing device, and the mass-flow-measuring device and the aperture of adjustable size are connected via a second control circuit, and the size of the adjustable aperture is set by this control circuit in such a manner that a defined quantity of bulk material enters the fluidizing device.

Device for gravimetric metering and pneumatic suction conveying of fluidizable bulk materials

The invention relates to a method for preparing homogeneous dispersions of fluidizable bulk materials, wherein, in a first step, fluidizable bulk materials are blended with liquid to produce a raw dispersion and, in a second step, the raw dispersion is conveyed through a continuous enclosed dispersing apparatus by means of a forced-conveyance apparatus.
