Product Introduction
WHAT IS CENTRIFUGE DECANTER
When you need to separate solid / liquid mixtures with high solids content, you can choose a decanter centrifuge. In contrast to chamber filter presses, these solid vortex centrifuges or decanter centrifuges operate continuously. High centrifugal forces separate finely divided solid particles from the suspension.
Our decanter centrifuges are modular in design and can be used in a wide range of industries. Centrifuges can be optimally adjusted for specific applications.
HOW DOES IT WORK
The feed product is pumped into the decanter centrifuge through an inlet. Feed into a horizontal bowl and then rotate. The bowl consists of a cylindrical portion and a conical portion. The separation takes place in the cylindrical part of the bowl. Fast rotation produces centrifugal forces of up to 4000 x g. Under these forces, solid particles with a higher density are collected and compacted on the wall of the bowl. The scroll (also a screw conveyor or screw conveyor) rotates inside the bowl at slightly different speeds. This speed difference is called a differential speed. In this way, the scroll conveys the precipitated particles along the cylindrical portion of the bowl to the conical end of the bowl. At the smallest end of the conical portion of the filter bowl, dehydrated solids leave the filter bowl through the discharge port. The clarified liquid exits through the mating disc (internal centrifugal pump).
With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.
Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the production of biodiesel .

The advantages of our product:
1. Industrial design
The whole machine set design follows the concept of advanced industrial design, ensuring the whole machine's stability, functionality, and safety. Also effectively absorbs the shear force of dynamic load during operation.
2. Effectively ease resonance during the rotating of bi-rotor
When the centrifuge works, there are no obvious first-order and two-order resonance regions within the designed speed range, meanwhile, the whole vibration intensity of the bearing seat is definitely 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 the phenomenon of liquid ring stalling
The phenomenon of liquid ring stalling happens during the heavy-duty boot or shutdown process of a complete set machine, especially for LW550 and even larger models, It would make a bounce or wild shake, causing extra impact fatigue damage to main bearings, screw bearings, and inner parts of the rotary bowl. Fortunately, our engineers have solved this problem thoroughly.
4. Unique technique adopts in main component work-blanks
The manufacturing methods of main component work blanks adopt the centrifugal casting technique and overall mold-making forging technique, thoroughly avoiding risks such as intergranular corrosion and relaxation of residual stress release in welding joints.
5. Main bearing electrical components selection
We use the origin bearings of international first-line brands such as S-K-F, F-A-G, etc. Electrical components mainly adopt ABB and Siemens
6. Constant temperature detection
All fashioning components and assembly units are detected in constant temperature conditions to ensure that 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 are interchangeable. It is not only easy to maintain, but also greatly improves the reliability and safety of the equipment.
8. Simply and safely in bearing disassemblement
One layer of oil film is injected into contact surfaces between the bearing and work-piece by high-
pressure, during the disassemblement bearing from the machine.which would fundamentally eliminate friction within different parts. As a result, it would reduce 90% of the pulling force and lower the risk of damage to high-precision parts when disassembling the bearings.
9. Automatic main bearing lubrication system
Thin oil lubrication
* Oil pump offers uninterrupted power to ensure oil works circularly;
* Jet oil lubrication constantly cleans and lubricates bearings and reduces temperature;
* Oil filter system ensures lubricant's cleanliness;
* Oil pressure energy storage system ensure lubrication pump offers an extra oil supply(the pressure is no less than 0.4Mpa) for 5-6 minutes when power fails accidentally;
* Constant temperature system is available.
* Adopt a grease with properties of extreme pressure resistance, oxidation resistance, abrasion resistance, water scour resistance,corrosion-proof, and high-temperature resistance.
* Automatic grease system fills grease on the main bearing at designed hours and quantity.
10. Main bearing BH device (patent design)
There are two spare safe bearings at either end of the main bearing. When the machine works well, they keep a certain clearance from the bearing inside the track to the chief axis. When an unexpected condition occurs, the main bearing getting damaged or circle center deviation causing an amplitude of vibration reaches to designed clearance, safe bearings begin to work as the main bearing Meanwhile, the computer's automatic control system would get feedback of abnormal vibration values on the bearing position immediately then activates emergency shutdown and goes a smooth shut down. This system protects the machine free from damage and ensures production safety.
11. GSRL feeding device (potent design)
The new design of the internal spiral core tube has got the following achieves. Without reducing centrifugal acceleration, shorten the triangle belt's traction time, reduce disorder of swirling flow, and extend separation time. Meanwhile increases the inner working pressure of the centrifuge, and restrains liquid from foaming
