  • Vertical separator for the treatment of slurry
    Patent number: 11130080
    Abstract: A vertical separator for the treatment of slurry includes a screen device with a vertical axis provided with a screen, a feeding device provided with a pump to feed the slurry to a screen device, a discharge device for the liquid part of the slurry, and a discharge device for the solid particles of the slurry. The screen device houses a counter-pressing device which is designed to generate a force which partially counters the pushing action exerted by the pump upon the slurry.

  • VERTICAL SEPARATOR FOR THE TREATMENT OF SLURRY
    Publication number: 20170144086
    Abstract: A vertical separator for the treatment of slurry. The vertical separator comprises: a screen device, with a vertical axis, provided with a screen; a feeding device, provided with a pump, to feed the slurry to a screen device; a discharge device for the liquid part; and a discharge device for the solid particles. The screen device houses a counter-pressing device (e.g. a screw, which is designed to generate a reaction, which partially counters the pushing action exerted by the pump upon the slurry.
