工作原理
懸浮液通過進(jìn)料管進(jìn)入轉(zhuǎn)鼓內(nèi)，在離心力場作用下密度較大的固相沉降至轉(zhuǎn)鼓壁上，固相在螺旋的推動下從沉降區(qū)至干燥區(qū)后從出渣口排出；澄清的液相從轉(zhuǎn)鼓大端溢流口溢出，實現(xiàn)固液分離。
LWS為三相分離型。
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.
LWS is three-phase separation type.
