工作原理悬浮液通过进料管进入转鼓内，在离心力场作用下密度较大的固相沉降至转鼓壁上，固相在螺旋的推动下从沉降区至干燥区后从出渣口排出；澄清的液相从转鼓大端溢流口溢出，实现固液分离
工作原理
悬浮液通过进料管进入转鼓内，在离心力场作用下密度较大的固相沉降至转鼓壁上，固相在螺旋的推动下从沉降区至干燥区后从出渣口排出；澄清的液相从转鼓大端溢流口溢出，实现固液分离。
LWF为防爆机型。
Operating principle
Once the suspension fed into the centrifuge drum via feed pipe, solid phase of it of higher density will be settled down and attached to wall surface of the rotor drum under effect of centrifuge field. which will be screw pushed to drying area before it's discharged via slag outlet，the clarified Iiquid phase of it will be overflowed via the overflow port of the rotor drum，hence to realize solid and liquid separation.
LWF is explosion-proof type.
