LW Series Horizontal Spiral Discharge Settling Centrifuge

Description:

●The rotating drum is made of duplex stainless steel integral centrifugal casting, and the inlet and outlet uses special wear-resistant materials. The strength and rigidity are far higher than ordinary stainless steel, with less vibration, better corrosion resistance, better wear resistance and longer service life；

●The structure of large aspect ratio is adopted, which lengthens the sedimentation area, prolongs the separation time, and has larger processing capacity and better effect;

●The spiral structure design is pertinent, which not only ensures the dryness of the mud but also makes the slag discharge smooth;

●unique in volute planetary gear differential with large transmission ratio, differential speed and torque can be flexibly adjusted;

●Special steel frame with strong bearing capacity and no deformation to ensure stable operation of the equipment.

●The wear-resistant parts of the spiral blade are made of special wear­ resistant alloy materials to ensure abrasion resistance and no rupture.

The rotating drum is made of duplex stainless steel by centrifugal casting. The rigidity and strength are greatly improved, vibration is reduced, and noise is reduced. The slag outlet is inlaid with ceramic sleeves or cemented carbide sleeves to improve wear resistance and corrosion resistance.

Model and technical parameter

Applications:

The LW series horizontal screw sedimentation discharge centrifuge is a highly efficient and continuous solid-liquid separation equipment, widely used in multiple industrial fields. It mainly relies on centrifugal force to separate solid particles from liquids in suspensions. Its typical application fields include:

1.Environmental protection and sewage treatment

Municipal sewage treatment: Dewatering of sludge (such as activated sludge and biochemical sludge), reducing the moisture content to facilitate subsequent disposal.

Industrial wastewater treatment: It is applicable to the dewatering of high-concentration wastewater sludge in industries such as chemical engineering, printing and dyeing, paper making, and electroplating.

River dredging: Dehydrating and reducing the volume of silt to lower transportation and landfill costs.

2. Chemical Engineering and Petrochemical Engineering

Catalyst separation: Recover the solid catalyst after the reaction.

Polymer treatment: Dehydration of synthetic resins such as PVC and PE.

Oil sludge treatment: Separate the oily sludge produced during the process of oil extraction or refining, and recover the oil.

3. Food and Bioengineering

Starch processing: Dehydration and washing of corn and potato starch.

Fermentation liquid treatment: such as the separation of yeast and antibiotic cells.

Juice clarification: Remove solid impurities such as pulp fibers.

4. Minerals and Metallurgy

Tailings treatment: Dehydrate the tailings from mines to achieve dry stacking or resource recovery.

Metal concentrate dehydration: Concentration and separation of minerals such as copper, zinc and aluminum.

Coal chemical industry: Coal slime dewatering and coal tar residue treatment.

5. Pharmaceutical industry

Separation of medicinal residue: Dehydration of the medicinal residue after extraction from traditional Chinese medicine.

Biological preparations: Solid-liquid separation of cell culture media and fermentation products.

6. Papermaking industry

Pulp dewatering: Fiber recovery in the process of waste paper regeneration.

White mud treatment: Calcium carbonate separation during the alkali recovery process.
