Product introduction:The slope screen spiral extrusion solid-liquid separator works continuously by means of spiral extrusion. It is suitable for materials with 0.3mm solid particles, large solid proportion in the feed liquid and low moisture content after separation. It is especially suitable for the dewatering and separation of pig manure (blister manure) with water content higher than 90% into liquid organic fertilizer and solid organic fertilizer. The solid-liquid separator divides the solid-liquid separation cylinder into centrifugal separation section and extrusion separation section, that is, the solid-liquid separation and solid-liquid separation of biogas residue are carried out through centrifugal separation and extrusion separation, the water content of biogas residue is greatly reduced, the drying time of biogas residue is reduced, the drying cost is reduced, and the time and cost are saved for users producing biogas fertilizer.
