Phase decanter centrifuge: Three-phase decanter centrifuge: It is a kind of horizontal decanter centrifuge equipment used to achieve the separation of liquid-liquid-solid three phases. In this centrifuge, through the centrifugal force field generated by high-speed rotation, substances in three different phases (two immiscible liquids and one solid) are separated according to the density differences.

One liquid phase (such as the light liquid phase with a lower density) will gather in the inner layer of the drum, and the other liquid phase (the heavy liquid phase with a higher density) will be in the outer layer of the drum, while the solid particles will settle on the inner wall of the drum. Then, through the corresponding discharge devices, the three-phase substances are respectively discharged from the centrifuge to achieve the purpose of separation.

Three-phase decanter centrifuges are widely used in the process operations involving liquid-liquid-solid three-phase separation in industries such as petrochemicals, food processing, and sewage treatment.

Phase decanter centrifuge：Two-phase decanter centrifuge: It is a kind of horizontal decanter centrifuge equipment mainly used to achieve the separation of solid-liquid two phases or two immiscible liquid-liquid two phases. When carrying out solid-liquid separation, through the powerful centrifugal force field generated by the high-speed rotation of the centrifuge, the solid particles settle on the inner wall of the drum, while the liquid is distributed inside the drum.

Then, the screw conveyor is used to push the settled solids to one end of the drum for discharge, and at the same time, the liquid flows out through a specific liquid discharge port, thus completing the solid-liquid separation. When carrying out liquid-liquid two-phase separation, two immiscible liquids with different densities are stratified according to the density difference under the action of centrifugal force. The liquid with a higher density is close to the outer wall of the drum, and the liquid with a lower density is close to the center of the drum. Then, they are respectively discharged through the corresponding liquid discharge ports to achieve liquid-liquid separation.

Two-phase decanter centrifuges are widely used in many fields such as chemical industry, pharmaceuticals, environmental protection, and food industry for the separation of various suspensions and emulsions.

Material Characteristics
Solid-Liquid Ratio: If the solid content is high, a centrifuge with a large processing capacity and strong slag-discharging ability should be selected; if the liquid content is high, there will be higher requirements for the separation efficiency and liquid clarity.

Particle Size: For materials with larger particles, the separation is relatively easy; while for materials with fine particles, the centrifuge needs to have a higher separation precision.

Material Viscosity: Materials with high viscosity will increase the difficulty of separation, and a centrifuge with strong anti-adhesion performance and stirring ability should be selected.

Corrosiveness: If the material is corrosive, the material of the centrifuge needs to have corresponding corrosion resistance, such as stainless steel, special alloys, etc.

Processing Scale
According to the production scale and processing capacity requirements of the enterprise, select the appropriate centrifuge model. Enterprises with a large processing capacity need to select equipment with strong processing capacity and a long continuous operation time.Shenzhou machinery is a good choice for your !

Pay Attention to Performance Indicators
Separation Factor: The separation factor is an important indicator for measuring the separation ability of the centrifuge. The higher the separation factor, the better the separation effect. For materials that are difficult to separate, a centrifuge with a higher separation factor should be selected.

Drum Diameter and Length: Generally speaking, the larger the drum diameter and the longer the length, the better the processing capacity and separation effect of the centrifuge. However, it will also increase the floor space and energy consumption of the equipment.

Differential Speed Control: The differential speed refers to the rotational speed difference between the screw conveyor and the drum. The size of the differential speed directly affects the slag-discharging effect and separation efficiency. An excellent centrifuge should be equipped with an accurate differential speed control system that can be flexibly adjusted according to the material characteristics and processing requirements.

Manufacturing Process: Check the welding quality, machining precision, assembly process, etc. of the equipment to ensure that there are no obvious defects or flaws.

Brand and Reputation: Choosing a well-known brand and a centrifuge manufacturer with a good reputation can reduce the purchase risk. You can understand the manufacturer's reputation and product quality by referring to industry materials, consulting peers, and checking user reviews.

Consider the Operating Costs
Energy Consumption: The centrifuge consumes a large amount of electricity during operation, so energy consumption is an important consideration. Selecting an energy-efficient centrifuge can reduce operating costs.

Replacement Cost of Vulnerable Parts: Understand the types, prices, and replacement cycles of the vulnerable parts of the centrifuge, and select equipment with lower vulnerable parts costs. At the same time, ensure that the supply channels for vulnerable parts are unobstructed for timely replacement.

Evaluate the After-sales Service
Technical Support: The manufacturer should be able to provide timely and professional technical support, including equipment installation and commissioning, operation training, troubleshooting, etc.

Spare Parts Supply: Ensure that the manufacturer can provide sufficient original spare parts to ensure the normal maintenance and replacement of the equipment.

Maintenance Service: Choose a manufacturer with a complete maintenance service network and a rapid response mechanism so that the equipment can be repaired in a timely manner when a failure occurs.
