Control device for a building board production plant

摘要

There is a control device for a building board production plant, in which a feed device (2) for setting agent has an adjustable throughflow element (24) and a moulding device for forming a board structure from a mixture containing the setting agent is provided. The control device desired here is one which continuously measures the setting behaviour of the mixture for the board structure in a precise manner and without prejudicing the board structure and actuates the throughflow element for the setting agent as a function of this measurement. This is achieved by virtue of the fact that a first heat-radiation measuring head (11) at the moulding device (9) is assigned to the board structure, a further heat-radiation measuring head (12) is arranged at a distance behind the first measuring head, the two measuring heads act on a control unit (19) and this adjusts the throughflow element (24). The measuring heads operate continuously and non-destructively and the metering of the setting agent is continuously monitored and correctly set.
