SEPARATION / CONCENTRATION Ｓcrew Decanter Concentration System
■　Structure BOWL A REVOLVING BODY IS COMPRISED OF A CYLINDRICAL SECTION AND A CONICAL SECTION. THE STRONG CENTRIFUGAL FORCE GENERATED BY ITS HIGH VELOCITY REVOLUTION SEPARATES SLURRY INTO CLEARED LIQUID AND SOLID PARTICLES. SCREW THERE IS A SLIGHT CLEARANCE BETWEEN THE SCREW AND THE INNER SURFACE OF THE BOWL, AND A SLIGHT DIFFERENCE IN REVOLVING SPEED. THE SCREW CONTINUOUSLY PICKS UP THE SOLID PARTICLES DEPOSITED ON THE INNER SURFACE 　OF THE BOWL, AND CARRIES THEN TOWARDS THE CONICAL SECTION OF THE BOWL. AT THE TAPERED PORTION, THEY ARE CONVEYED TOWARDS THE SOLID PARTICLE OUTLET, WHILE DEHYDRATING SIMULTANEOUSLY. FEED PIPE FEED PIPE PASSES THROUGH THE CENTRAL PART OF THE EQUIPMENT TO SUPPLY ORIGINAL LIQUID AT THE BEST POSITION WITHIN THE MACHINE. THE POSITION IS ADJUSTED ACCORDING TO THE CONDITION OF THE TREATMENT.
■　Principles of Separation THE PRE-TREATENT LIQUID (SUSPENSION) IS FED VIA THE FEED PIPE INTO THE BOWL, WHICH IS REVOLVING AT HIGH SPEED. 　　　　　　　　　　　　　　　　　　　　 THE CENTRIFUGAL FORCE EXERTED ON THE LIQUID AS IT FORMS A REVOLVING RING INSIDE THE BOWL, IS ENORMOUS; AS MUCH AS 3500 TIMES THE FORCE OF GRAVITY (3500 X G). THIS MASSIVE CENTRIFUGAL FORCE CAUSES THE SOLID PARTICLES WITH A HIGH DENSITY PRESENT IN THE LIQUID TO QUICKLY PRECIPITATE, SO THAT TWO SEPARATE LAYERS, ONE OF SOLID PARTICLES AND ONE OF CLEARED LIQUID, ARE FORMED ON THE INNER WALL OF THE BOWL. THE CLEARED LIQUID AND SOLID PARTICLES SEPARATED ARE CONTINUOUSLY DISCHARGED FROM THE EQUIPMENT. FOR THE DISCHARGE OF THE SEPARATED CLEARED LIQUID, A DISCHARGED OUTLET (A) LOCATED AT THE WIDE END OF THE BOWL PROVIDES AN OVERFLOW FOR THE LIQUID UNDER CENTRIFUGAL PRESSURE. FOR THE DISCHARGE OF THE SEPARATED SOLID PARTICLES, THE SCREW CONVEYOR (B) TURNS AT A FRACTIONALLY DIFFERENT SPEED TO THE BOWL, THUS CONVEYING THE SOLID PARTICLES TOWARD THE CONICAL END OF THE BOWL, WHERE THEY ARE DISCHARGED BY CENTRIFUGAL FORCE THROUGH THE SOLIDS DISCHARGE OUTLET (C) LOCATED AT THE NARROW END OF THE BOWL. 　　　　　　　　　　　　　　　　　　　　　　 THE MECHANISM ALLOWS THE CONTINUOUSLY SUPPLIED PRE-TREATMENT LIQUID TO BE CONTINUOUSLY SEPARATED, AND THE SEPARATED SOLIDS AND CLEARED LIQUID TO BE DISCHARGED FROM THEIR RESPECTIVE OUTLET
