LW Horizontal Decanter Centrifuge


Product Description
The LW series horizontal decanter centrifuge is one of the main equipments of the sludge dewatering system. It is mainly composed of a high-speed rotating drum, which has the same rotation as the drum and forms a spiral with a certain speed difference, such as a differential and a frame. Component composition. When the sludge enters the inner cavity of the centrifuge drum, the high-speed rotating drum produces a strong centrifugal force. The sludge particles are dense and generate a large centrifugal force, so the sludge is settled on the inner wall of the drum to form an annular solid phase Mud cake layer; and the density of water is small, the centrifugal force is also small, can only form a liquid ring layer inside the solid ring layer, due to the different rotation speeds of the screw and the drum, the two have relative motion (that is, the differential rotation speed), through the screw handle The sludge deposited on the inner wall of the drum is pushed to the outlet of the small end of the drum, and the separated water is discharged from the other end of the drum. The function of the differential is to form a certain speed difference between the drum and the spiral. Flocculants are added to the mud to produce flocculation, which makes the dispersed sludge particles aggregate to produce larger flocs and accelerate the separation of mud and water.

Operating Principle
The main engine starts and automatically increases the speed. When the predetermined index is reached and the drum reaches the feeding speed, the feeding valve opens, and the suspension to be separated enters the silo of the screw propeller through the feeding pipe, and enters the silo through the outlet of the silo after preliminary acceleration. In the drum, due to the centrifugal force, the suspension in the drum is quickly divided into two phases. The heavier solid phase settles on the inner wall of the drum. Due to the differential action of the differential, there is a relative movement between the screw pusher and the drum. The solid phase is screwed to the drying zone at the small end of the drum for further dehydration, and then discharged through the slag outlet, and the separated liquid is discharged through the large end overflow.

Main Features

High Efficiency
Continuous operation, large production capacity, stable performance.

Low Consumption
Low power consumption.

Effective Washing
When the purity of the solid product is required, it can be effectively washed, and the washing liquid and mother liquor can be discharged separately.

High Separation Factor
The machine has a high volume of separation factor, the material can be fully dehydrated in the primary and secondary drum, and the filter cake contains less water than normal machines.

Use and Performance
LW horizontal decanter centrifuge is a sedimentation centrifuge with continuous working and continuous spiral discharge. It is mainly suitable for the solid-liquid separation, particle size classification, liquid phase clarification and sludge dewatering of various types of suspensions in various industrial sectors (such as: polyvinyl chloride resin, ammonium sulfite, barium carbonate, strontium sulfate, lithopone, titanium dioxide, Ore, china clay, kaolin, diatomaceous earth, starch, soy protein, peanut protein, fruit juice, beverage, vegetable oil, citric acid, waste oil purification, washing water purification, vinasse, animal fat, blood meal, power plant sludge, printing and dyeing sludge, Papermaking sludge, natural gas desulfurization sludge, calcium carbide sludge, activated sludge, ammo-nia sludge, car wash sludge, alum sludge, drilling mud, coal flotation waste, cryolite flotation fluid, etc.).
