Arrangement for dosing and distribution of dispersed goods, e.g. for distributing salt

摘要

The arrangement has a regulating device (19), especially a PID regulator, which operates with a stored load characteristic field in which the load dependent parameters are stored in the form of the pressure difference or torque on the hydromotor depending on the mass flow at the scattering distributor (14) for different revolution rates. An actual mass flow measurement value is determined from this depending on the first input parameter, i.e. revolution rate. A control error is derived from the actual mass flow and demand mass flow and processed into a second control parameter for the dosing device (13).
