A screw decanter centrifuge is a high-performance separation equipment that utilizes centrifugal force to separate substances with different densities. It features a continuous operation design, making it efficient for the processing of liquid-solid mixtures and liquids with varying specific gravities. The screw conveyor system within the centrifuge helps in the efficient transportation and dewatering of solids, while the conical bowl allows for effective separation due to the increasing centrifugal force towards the outlet.


SZLW series showcases exceptional versatility in concentrating, dewatering, and classifying suspensions containing solid particles. This range extends from minuscule microns to larger millimeters in particle size. In industries such as chemicals, pharmaceuticals, wastewater treatment, and printing and dyeing, the screw decanter centrifuge emerges as an indispensable tool. SZLW series embodies this necessity, offering unparalleled performance across diverse applications.

Decanter centrifuges are core equipment for the industrial separation of pectin. With their adaptability to high-viscosity materials, continuous operation capability, and efficient solid-liquid separation performance, they perfectly match the characteristics of pectin extracts (high viscosity, containing fibrous impurities). The following is a detailed explanation from the perspectives of technical principles, application scenarios, core advantages, operation key points, and development trends:

Brief introduction


Horizontal spiral decanter centrifuges can generally be divided into horizontal spiral filtration centrifuges and horizontal spiral settling centrifuges. Horizontal screw centrifuge is a settling equipment with horizontal spiral discharge and continuous operation

1、 Characteristics of LW900 × 3600NYD-1 horizontal spiral discharge settling centrifuge
1. Wide applicability
A suspension with a solid phase weight of 2:510%, a liquid-solid volume concentration of zG50%, and a liquid-solid density difference of 30.05 μ m and a cloud diameter of 55m can be used for separation, dehydration, purification, and classification. When the density difference between the solid and liquid phases is large, the solid phase position can also be separated with a diameter of 325m.
2. High degree of automation
Can achieve continuous feeding and discharging. Under the action of centrifugal force, the solid phase calibrator is continuously pushed towards the small end of the drum by the spiral, and the clear liquid phase is discharged from the large end of the flow outlet along the spiral Thus achieving continuous automatic operation.
3. Easy to adjust
Adopting advanced frequency converters, it has the advantages of low energy consumption and stepless adjustable working speed. The diameter and differential speed of the diffuser plate can be adjusted appropriately according to the material properties. The machine is equipped with an advanced hydraulic differential system, which has a large output torque, automatic differential feedback adjustment, and automatic compensation for pushing power. Automatically restore to initial state after eliminating overload, less likely to cause material blockage.

The horizontal spiral decanter centrifuge is mainly used for solid-liquid separation processing in production and pollution control of production wastewater, and is applied in wastewater treatment in fields such as steel rolling mills, coal washing and mineral processing, papermaking and leather making. Different processing objects definitely have different requirements for machine performance parameters, so it is necessary for the equipment to be able to achieve adaptive adjustment.

A tube centrifuge consists of a body, transmission device, drum, collection plate, and inlet bearing seat. The upper part of the drum is a flexible spindle, and the lower part is a damping floating bearing. The main shaft is connected to the passive wheels through a connecting seat buffer. The motor transmits power to the driven wheel through a conveyor belt and tension wheel, causing the drum to rotate at high speed around its own axis, forming a strong centrifugal force field. The material is injected from the bottom inlet, and centrifugal force forces the liquid to flow upward along the inner wall of the drum, resulting in layering due to the density differences of different components of the liquid. Tube centrifuge is currently an ideal centrifugal separation equipment. Tube centrifuge is mainly used for liquid-solid, liquid-liquid or liquid-liquid solid three-phase separation. Its smallest separation particle size is 1 micron, which is particularly suitable for extraction, concentration, and clarification of liquid-solid phase differences, small solid phase particle size, low content, and strong corrosiveness of the medium.

A horizontal screw centrifuge is a spiral discharge settling centrifuge. It mainly consists of a high-speed drum, a screw conveyor with a hollow shaft that rotates in the same direction as the drum and has a lower speed ratio than the drum, and a differential. When the suspension to be separated is sent into the drum by the hollow shaft, it is immediately thrown into the drum cavity under the centrifugal force generated by high-speed rotation. The high-speed rotating drum generates strong centrifugal force, which throws solid particles with higher density than the liquid phase onto the inner wall of the drum, forming a solid layer (called a solid ring layer due to its ring shape); Due to its low density and centrifugal force, water can only form a liquid layer inside the solid ring layer, known as the liquid ring layer. Due to the different rotational speeds of the spiral and the drum, there is a relative motion (i.e. speed difference) between the two. The relative motion between the spiral and the drum is used to slowly push the sludge in the solid ring layer to the cone end of the drum, and after passing through the drying zone, it is continuously discharged through the outlet distributed around the circumference of the drum; The liquid in the liquid ring layer is continuously 'overflowed' by gravity from the weir to the outside of the drum, forming a separated liquid.

A horizontal spiral centrifuge is a settling equipment that operates continuously and discharges materials horizontally. The drum and the screw rotate at a certain speed difference in the same direction and high speed. The material is continuously introduced into the inner cylinder of the conveying screw through the feeding pipe, accelerated and enters the drum. Under the action of the centrifugal force field, heavier solid substances deposit on the drum wall to form a sediment layer. The feeding spiral continuously pushes the deposited solid phase to the cone end of the drum and discharges it outside the machine through the slag discharge outlet. The lighter liquid phase forms an inner liquid ring, which continuously overflows from the large end overflow port of the drum and is discharged outside the machine through the discharge port.
