LW Series Horizontal Spirals Discharging Sedimentation Centrifuge

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 feeding valve opens and allows suspension to be separated to enter into the compartment of the spiral feeder through the feeding pipeline, After preliminary speed-up, the suspension passes the outlet of the compartment and into the revolving drum. In response to the centrifugal force, the suspension in the drum is quickly divided into two phases: the heavier solid phase deposits to the inner wall of the drum, and driven by the differential gear which results in the non-synchronous movement between the spiral feeder and the drum, the solid phase is transferred into the small 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.

Properties and Uses

LW Series Spiral Discharging Sedimentation Centrifuge is a horizontal, continuously working and continuously spiral discharging sedimentation centrifuge. It is used in a variety of industries for separating all 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, porcelain, clay, kaoline, diatomite, amylum, soyaabean protein , earthnut protein , syrup, beverage, vegetable oil, citric acid, scavenge oil purification, cleansing water purification, lees, tallow, blood powder, sludge from power plants, sludge from printing and dyeing, sludge from paper making, sludge from desulfurizing natural gas, calcium carbide sludge, activated sludge, ammonia sludge, sludge from washing cars, alum sludge, drilling mud, coal flotation waste, cryolite flotation liquid.
