LW400 Series Two Phase Horizontal Type Spiral Discharge Decanter Centrifuge For Sludge Dewatering Treatment

LW400 Series Two Phase Horizontal Type Spiral Discharge Decanter Centrifuge For Sludge Dewatering Treatment
Product Details

Horizontal spiral discharge decanter centrifuge referred to as horizontal screw centrifuge, it is an efficient centrifugal separation equipment. LW400 series two phase horizontal spiral discharge decanter centrifuge is widely used in chemical industry, light industry, pharmaceutical, food, environmental protection and other industries.

The centrifuges offer a range of aspect ratios and various models to choose from, designed with a unique advantage that enables to separate feeds which are difficult to separate, such as viscid grains and those with low relative density.

Scope of application
①TiO2 Size grading of suspension
②Separation of Oil drilling mud

③Clarification & separation of plant oil
④Separation of fruit juice
⑤Solid-phase separation for fish oil and water for fish processing, to produce high quality fish meal
⑥Separation & dewatering of instant tea

⑦Size grading for Bentonite, Kaoline and other nonmetallic ore

⑧Centrifuge for sludge treatment

⑨Separation of grape juice and dregs

⑩Separation of cutting fluid silicon carbide
