Decanter Centrifuge Machine For Humic Acid Potassium extraction
Humic acid potassium extraction using decanter centrifuges is a highly efficient process for separating humic acid potassium from raw materials. The decanter centrifuge applies centrifugal force to rapidly separate the solid and liquid phases, ensuring a high yield of humic acid potassium with minimal impurities.
During the extraction process, the decanter centrifuge continuously feeds the raw material into the bowl, where the centrifugal force separates the solid particles from the liquid. The separated humic acid potassium solution is then discharged through the liquid outlet, while the solid residue is collected and removed through the solids discharge port.
The decanter centrifuge's adjustable parameters allow precise control over the separation process, optimizing the extraction efficiency. Its continuous operation and high processing capacity ensure a steady and productive workflow.
With its robust design and automatic operation, the decanter centrifuge requires minimal manual intervention, reducing labor costs and ensuring consistent product quality. This extraction method is widely used in agriculture, horticulture, and other industries for its effectiveness in obtaining pure and concentrated humic acid potassium products.

Decanter Centrifuge Operating principle
The purpose of separation is to separate out substances with different mass ratios from mixed fluid.Separation forms included solid-liquid separation,liquid-liquid separation and liquid-liquid-solid separation.
When mixed fluid enters rotating bowl of centrifuge through feed tube ,solids with larger density would rapidly deposit on inner wall of the bowl,forced by centrifugal acceleration.Then spiral pusher pushed deposited solids to taper end of the bowl,and discharges them out of centrifuge from residual outlet.Meanwhile ,liquid phase with smaller density forms a liquid ring layer and discharges from bowl through overflow port,the bowl and spiral pusher run at a high speed simultaneously ,for there exists speed discrepancy,deposited solids on the wall of bowl could be conveyed to residue outlet by spiral pusher.This separation process carry out continuously.

The decanter centrifuge can be adjusted to suit individual requirements by varying:
- Bowl speed to ensure the exact relative centrifugal force required for optimized separation.
- Differential speed, for optimized balance between liquid clarity and solids discharge capacity.
- Pond depth in the bowl for optimized balance between liquid clarity and solid dryness.
Material: high quality stainless steel
Bearing: SKF brand. A special selection and arrangement of bearings provides for long life and exceptional reliability.
Wear protection: carbide sheets of spiral feeder and replaceable alloy sleeves of drum outlet and spiral feeder outlet.

▍ Main Technical Features
1. Industrial design
Whole machine set design follows concept of advanced industrial design,ensures stability, functionality and safety of whole machine.Also effectively absorbs shear force of dynamic load during operation.
2. Effectively ease resonance during rotating of bi-rotor
When centrifuge works,there is no obvious first-order and two-order resonance regions within designed speed range,meanwhile ,whole vibration intensity of bearing seat is definited within 2mm/s-4mm/s.All of this eliminates extra fatigue damage to components and assembly units from high frequency vibration during operation and sudden vibration when shut down.
3. Thoroughly eliminate phenomenon of liquid ring stalling
Phenomenon of liquid ring stalling happens during heavy duty boot or shutdown process of complete set machine,especially for LW550 and even larger models,It would makes bounce or wild shake,causes extra impact fatigue damage to main bearings,screw bearings and inner parts of rotary bowl.Fortunately ,our engineers have solved this problem thoroughly.
4. Unique technique adopt in main component work-blanks
The manufacturing methods of main component work-blanks are adopt centrifugal casting technique and overall mould-making forging technique,thoroughly avoid risks such as inter-granular corrosion and relaxation of residual stress release in welding joint.
5. Main bearing selection
We use origin bearings of international first-line brands such as SKF,FAG and so on.
6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature condition,to make sure of actual processing quality meets the requirements of designed precision accuracy.
7. Inter-change ability
Whole machine physical design and processing technique adopted in critical position,ensure all assembly units and bowls of the same centrifuge model interchangeable.It is not only easy to maintain ,but also greatly improve the reliability and safety of equipment.
