Title: Method for dosing bulk material
Inventor: ETTENHOFER ANTON
IPC: G01F13/00
Filed: 1997-04-15
Abstract: The method involves using a worm doser, to rotate about an angular value (n4,n4*,n4**).

Also the necessary corrections for attaining an angle amount corresponding to the bulk material amount are evaluated in the control unit (23), using an algorithm pattern. The control unit forms new setting parameters for the position regulator (35) from the results of the evaluation, and these new parameters are used at least for the following dosing operation.
