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

  • Description
Product Detail

    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
    ?TiO2 Size grading of suspension
    ?Separation of Oil drilling mud

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

    ?Size grading for Bentonite, Kaoline and other nonmetallic ore

    ?Centrifuge for sludge treatment

    ?Separation of grape juice and dregs

    ?Separation of cutting fluid silicon carbide
