Automatic Horizontal Decanter Centrifuges Calcium Carbonate Dewatering Machine

LWF 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, kaolin, diatomite, amylum, soybean 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 papermaking, 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.

This machine is a countercurrent horizontal spiral discharging and settling centrifuge (horizontal screw centrifuge or centrifugal dehydrator for short), and the main machine is composed of column and cone drum, spiral discharging device, differential, bearing seat, frame, housing, main and auxiliary motors, and electrical system. Its working principle is the suspension after the feed pipe and spiral discharging mouth into the drum, under the effects of the centrifugal force at high speed, a high proportion of solid phased particles deposited on the inner wall of the drum, the drum for relative motion of the helical blade will continuously of solid phased particles deposited on the drum wall scraping, spiral pusher of solid phased particles will scrape the specially designed the structure of the two-way extrusion

Basic principles

For the auto decanter centrifuges stable performance sludge dewatering separator, the continuous feeding, separating, and discharging can be realized as it rotates at its full speed. It is characterized by compact structure, easy obturation, smooth running, low noises, large handling capacity, low energy consumption, high automation, small working strength, simple operation and easy maintenance, and wide applications.


1. Feeding pipe 2. Discharge screw 3. Drum 4. Casing 5. Differential mechanism

Working principle

The drum and the spiral feeder rotate in the same direction but with a certain speed difference; the material

is led into the feeding spiral inner cylinder via the feeding pipe and, after speeding pipe and, after speeding

up, enters the drum; under the action of the centrifugal force field, the relatively heavier solid-phase material deposits on the drum wall forming the residue layer; the solid-phase residue is continuously pushed by the spiral feeder to the conic end of the drum and, after dehydration in the drying area, is discharged out of the machine. The machine is capable of continuous feeding, separating, dehydrating, and discharging under full-speed running.
