Phase Decanter Centrifuge
3 Phase Decanter Centrifuge KWLWS is also called tricanter, is widely used for oil, water, solids separation industry. KWLWS Series Three-phase Decanter Centrifuge is mainly composed of rotating body assembly, planetary gear differential, motors, double frequency converters, base, fully-closed housing, feeding pipe assembly, and automatic control system, and can perform liquid-liquid-solid or liquid-solid-liquid three-phase separation for multiple suspensions with large differences in materials.
3 Phase Decanter Centrifuge KWLWS often is used in three-phase separation of food waste, edible oil separation, industrial waste oil separation, coal tar separation, yeast and starch separation etc.
Working principle of 3 Phase Decanter Centrifuge
3 Phase Decanter Centrifuge is turned on and automatically up to preset speed. Then open the feeding valve and the suspension is pumping into the rotating body assembly. The suspension in bowl is divided into three phases quickly under the action of centrifugal force. The differential action of differential gear makes relative movement generated between screw and bowl, and the heaviest solid phase settles on inner bowl wall and is pushed to discharged through drainage port. At the same time, the heavier liquid phase (such as water) is close to inner bowl wall while lighter liquid phase (such as oil) is distant from inner bowl wall. The overflow baffle plate can adjust and realize the separation effect of different sediments and liquid phases. The separated light liquid is discharged through overflow port while the separated heavy liquidis discharged by centripetal pump at big end of basket
