Method for controlling chemical- or auxiliary fuel supply at solid-liquid separation of suspensions by using optical system, involves using measuring values from optical determination for regulating metering of chemicals

摘要

The method involves using the measuring values from the optical determination for regulating the metering of the chemicals, additives or the suspension that is applied in a separator. The performance of a supply pump or the dosing pumps is regulated with the help of closed loop over frequency changer or the drives of the pumps or conveyors.
