Abstract (en)
[origin: WO2017001231A1] A method for controlling the liquid level in the premixing unit (500) of a Hatschek machine (1000) comprising a sheet manufacturing machine (100), a cement slurry preparation mixer (200), a settling tank (300), a selectifier (400), and a premixing unit (500), wherein a level meter measures the liquid level in the premixing unit and generates a measurement signal, and wherein said measurement signal directly or indirectly controls a control valve (801), such that the amount of the portion of the water-loaded cement slurry of the sheet manufacturing machine (100) that is supplied to the selectifier (400), is controlled.
