LW Series Horizontal SpiraI Discharing Sedimentation Centrifuge

Perormance and use:

LW Serials Spiral Discharging Sedimentation Centrifuge is a horizontal,continuously working and continuously spiraI discharging sedimentation centri- fuge.It is used in a variety of industries for separating alI kinds of solid-liquid suspension, defecating liquid phase with graded grains, and dehydrating sludge such as:polyoxyethylene,sulfurous acid,tansuanbei, strontium sulfate, lidefen, titanium pigment, ore, porc- elain clay,kaoline,diatomite,amylum,soyabean protein, earthnut protein, syrup, beverage, vegetable oiI, citric acid,scavenge oil purification, cleansing water purific- ation, lees, tallow. blood powder, sludge from power plants, sludge from printing and dyeing,sludge from paper making,sludge from desuIfurizing natural gas, calcium carbide sludge, activated sludge,ammonia sludge,sludge from washing cars,alum sludge.driIling mud,coaI flotation waste cryolite flotation Iiquid. 

Working principle:

The machine starts and speeds up automatically. When the proper working conditions are met and the revolving drum reaches the feeding speed, the feed -ing valve opens and allows suspension to be separa -ted to enter into the compartment of the spiraI feeder through the feeding pipeline After preliminary speed- up,the suspension passes the outlet of the compart -ment and into the revolving drum. In response to the centrifugaI force,the suspension in the drum is quickly divided into two phases: the heavier solid phase depo -sits to the inner waII of the drum and driven by the differentiaI gear which resuIts in the nonsynch ronous movement between the spiraI feeder and the drum, the solid phase is transferred into the smalI end for further dehydration and is finally discharged through waste exit.The separated liquid is discharged through the big end or driven out by the centripetal pump.

Main characteristics

1.Continuous working spiral discharging,high capacity 

2.Compact structure and easy maintenance. 

3.Wide applicability for chemical, oil, foodstuff, pharmacy industries and environmental protection in which solid-liquid separa -tion is required. 

4.Suitable for various materiaIs, capable for separating wide-ranging solid phase grains (0.005-2mm) working normally when separating solid phase protection in which solid-Iiquid separation is required. With grains of different sizes.
