GN Company Constant Torque self-adaptation Function for Decanter Centrifuge

GN Company is a professional manufacturer of Decanter Centrifuge, with capability of manufacturing Centrifuge with bowl diameter of 220mm~760mm, capacity of from 1~2m3/hour to 120m3/hour. GN Technical Team is a very professional team, with experience of R&D for more than 10 years.

Here are introduction about Constant Torque self-adaptation Function for GN Decanter Centrifuge.

When concentration changes, the current of back motor (for driving screw) would fluctuate accordingly.

1. When the monitored current value of back motor exceeds set value, the differential speed of centrifuge is too low, the control-programming program automatically controls the back motor working current to decrease to the preset value, and increases the differential speed of centrifuge.

2. When the monitored current value of back motor returns to normal setting value range, the control-programming program automatically controls the auxiliary motor working current to return to the preset value, and the differential speed of centrifuge returns to the normal.

3. When the monitored current value of back motor is low to the set value, the differential speed of centrifuge is too high, the control-programming program automatically controls working current of back motor to rise to the preset value, and reduces the differential speed of centrifuge.

4. Constant Torque self-adaptation Function can ensure the uniform of dry humidity of sludge (discharged from Centrifuge), and avoid the plugging problem caused by concentration change of feeding sludge, which provides reliable guarantee for the normal and stable operation of centrifuge.

GN Company Technical Department’s Suggestions about Centrifuge for Clarification Application

For the mixture of large amount of liquid phase and small amount of solid phase, Clarification means to remove the small amount of solid phase from the liquid phase, to make the liquid phase as clean as possible.

(1) Physical Specifications
Clarify the solid phase in the liquid phase, and size, shape, properties of the particles contained in the solid phase, as well as the liquid phase temperature, Ph, viscosity, and specific gravity of the liquid-solid.

(2) Liquid Phase Requirement after Clarification
Solids content in the liquid phase, and moisture content in the solid phase.

(3) Selection of the Centrifuge Model
The big amount of liquid phase has a small amount of solid phase, and the particle size of the solid phase is very small (less than 10 μm) or amorphous mycelium. GN Technical Engineers suggest clients to consider about Decanter Centrifuge, Disc Centrifuge, or Tube Centrifuge. Tube or Disc Manual Slag Discharge Centrifuge can be applicable if the solid phase content is <1% and the particle size is <5µm. If the solid phase content is ≤3% and the particle size is <5µm, Disc Piston Slag Discharge Centrifuge is better. Tube centrifuge has high separation factor (f≥1000), which can separate smaller particles with particle size of about 0.5um, and obtain clear liquid. After separation, the solid residue is closely attached while cannot transfer. It is dry attached to the inside of drum. So the machine needs to be disassembled and cannot be continuously procedured when the dross is removing. And for facilitating the dross removal, some of the drums are lined with a thin plastic paper tube, and the paper tube can be pulled out when the dross is discharged. Disc Centrifuge also has high separation factor (f = 1000). Due to the disc combination, the sedimentation area is large and the sedimentation distance is small. The resulting clear liquid is also good, and the processing capacity is larger than that of the tube centrifuge, but the separation result is that the solid phase produced is also deposited on the inner wall of the drum, and it needs to be dismantled regularly to remove slag, so it cannot be continuously produced.

Welcome to contact GN Sales Managers, and we would find out the best and exact separation solution for your project.

Overview about Centrifuge’s Applications and Selection

Compared with other separation equipment, Centrifuge can be used not only to get low moisture solid phase and high purity liquid phase, but also it has advantages of small footprint, good sealing, continuous operation, and automatic remote control, etc. So Centrifuge is widely used in chemical, petrochemical, petroleum refining, medicine, food, textile, metallurgy, coal, shipbuilding, environmental protection, military industry, and others. Such as purification and reuse of drilling mud for petroleum, sludge concentration and dehydration for sewage treatment, refining of petrochemical products, extraction of antibiotics and pesticides, production of milk, yeast, beer, fruit juice, sugar, orange oil, animal and vegetable oil, and fabric fiber dehydration, production of starch and other food, fabric fiber dehydration, purification of lubricants and fuel oil, etc. Centrifuge has become widely used separation equipment for different industries of the national economy.

There are different processing requirement in the production process, including Dehydration, Clarification, Concentration, Classification, and Separation. The essence of Dehydration and Clarification is to separate solids and liquid in the suspension, Dehydration is to remove liquid phase from solid phase, and Clarification is to remove solid phase from liquid. Concentration is to increase the content of solid phase in the solid-liquid mixture. Classification is the separation of particles of different size in the suspension. Separation generally refers to the separation of two mutually incompatible liquid phases.

GN Company Developed New Market for Decanter Centrifuge

GN Company Technical Engineers developed new Technology for Decanter Centrifuge, including dewatering, separation, and clarifying.

Dewatering Decanter Centrifuge is mainly used for dewatering of municipal and industrial wastewater sludge. It is designed for easy separation material, such as coarse particle size, high density difference of solid and liquid, low viscosity, high concentration. And its main application is for drilling mud, ETP, WWTP, oily sludge, cutting fluid, etc.

Separation Decanter Centrifuge has beach angle of 15 degree, it is designed both for clarity of liquid phase after separation, also for the dryness of solids phase. The decanter centrifuge is especially suitable for find soft material separation, which is difficult to separate. This decanter centrifuge is suitable for small particles, small density difference of solid and liquid, large viscosity and small concentration. And its main application is for soybean milk, plant starch recovery, fermentation liquid, baths, etc.

Clarifying Decanter Centrifuge, with beach angle of 20 degree, suits for small particle size, low density difference between solids and liquid, moderate viscosity, moderate concentration. And its main application material is for Edible Oil, Pectin, Plant Protein, Animal Protein, Starch, Juice, etc.

Decanter Centrifuge

Besides Decanter Centrifuge, GN Company also manufactures and supplies Chemical Dosing Unit and Progressive Cavity Pump. Simple mechanical separation can only be used to separate particles of 2~ 5 microns and Chemical Dosing Unit working together with high speed Decanter Centrifuge can separate the fine solids less than 2 microns.
