Abstract
A method of and apparatus for operating a dosing arrangement for good and poorly flowing loose material such as pulverized material, granular material, and similar material having different specific weights, flow properties, and other properties. The dosing arrangement is operated volumetrically, has a dosing device, such as a worm, which is provided with a controllable or variable drive, and has a gravimetrically operable measuring device which is combined with a belt conveyor which follows the dosing device in sequence and is provided with a similarly controllable or variable drive. The drive for the dosing device and/or belt conveyor is adjusted prior to the start of a dosing process in such a way that a predetermined ratio exists between the two drives for achieving, independent of a preset conveying thickness, a desired thickness of the load of the conveyor belt in relation to the drive speed of the conveyor belt.
