Device and method for the production of a binder mixture as well as a system for the production of material panels

The invention relates to a device (1) for producing a binding agent mixture (12) in the course of the production of material panels， the binding agent mixture (12) comprising at least one binding agent and a liquid， with at least one storage container (3) in which a first premix ( 10) is supplied from binder and liquid and temporarily stored， with at least one pump (4)， which is arranged after the storage container (3) and conveys a second premix (11) from the at least one storage container (3)， and with a supply device (6) which is arranged after the pump (4) for supplying a further liquid ( 13) to the second premix (11) for producing the binder mixture (12). The invention is characterized in that before and / or after the at least one storage container (3) at least one sensor (S1， S2， S3) for determining the binder content in the first premix (10) and / or second premix (11) and / or the binder mixture (12) is arranged. The invention also relates to a system (20) for producing panels (6) and a method for producing a binder mixture.
