Measurement and Control for SolidLiquid Separation Process

The core of thickening process control is to adjust the underflow ore drawing speed in time according to different working conditions. When flocculant is added, it is necessary to adjust the amount of flocculant in time to obtain the best sedimentation velocity, so that the underflow ore discharging speed and ore discharging concentration are in the best matching interval.
