Wide-ranging performance
Decanter Centrifuge from Hongji Separator provide exceptional performance when separating solids from liquids, and make it possible to do so continuously,efficiently and controllably.
Hongji decanter centrifuges are designed to handle a wide range of solid particles with diameters from 5mm to a few microns.
Decanter centrifuge can also handle slurries with a solid content from as low as 0.1% w/w to more than 65% w/w.
2 - phase separation
- 1. Feed
- 2. Liquid phase
- 3. Solids phase
- 4. Pond
- 5. Dry beach
The feed suspension is introduced through an inlet pipe into the feed zone of the conveyor where it is accelerated and directed into the interior of the bowl. The settled solids are conveyed axially towards the small end of the bowl by means of the screw conveyor, which rotates at a slightly different speed than the bowl. On the way to the discharge ports the solids are lifted out of the pond up along the dry beach. The solids are finally discharged from the bowl through the discharge ports into the collecting chamber of the casing that surrounds the bowl. From there the solids are removed by gravity through the outlet funnel. The liquid phase forming a hollow cylinder due to the centrifugal force, and flows towards the large end of the bowl. There the liquid overflows adjustable plate dams into the centrate chamber of the casing and is discharged by gravity.
3 - phase separation
- 0. Food
- 1. Light liquid phase
- 2. Heavy liquid phase
- 3. Solids phase
The light liquid phase is discharged into the casing through radial holes in the large end hub. The heavy liquid phase is discharged through axial holes in the large end hub. The liquid radius for the light liquid phase is smaller than the radius for the heavy liquid phase. The liquid level is controlled by plate dams. In order to prevent the light liquid phase from leaving the bowl through the heavy liquid phase outlet, a separating plate is placed on the inside of the large end hub. The heavy liquid phase has to pass under the separating plate before being discharged into the casing. The liquid radius for the heavy liquid phase is controlled by plate dams. The solids are discharged in the normal way.

Hongji Separator supply a wide range of wear protection to meet the requirements of the many different applications, including:
Welded hard facing or spray coating
Ceramic
Tungsten carbide tiles
Chilled hard metal portcastings
Plastic liners
Design
The rotating part of these avocado oil tricanter centrifuges is mounted on a compact, in-line frame, with main bearings at both ends. Vibration dampers are placed under the frame. The rotating part is enclosed in a casing with a cover and a bottom section with integrated outlets for both solids and the liquid being removed.
Decanter centrifuge drive system
One motor drive, this is a very simple design and are therefore cheap to purchase and operate. One motor drive are used when the solids volume is constant, the solids are easy to convey and the requirements regarding the residual water content of the solids are not very stringent, in other words, bowl and differential speed regulating facilities are not necessary. The input shaft of the drive is set in motion by the main motor via a second belt drive. This generates the differential speed as a function of bowl speed and gear transmission. This can be easily changed by replacing the belt pulleys.
Two motor drive, it enable the differential speed to be regulated cost-effectively under good operating conditions; wide regulating ranges are possible. The secondary motor sets the input shaft of the gear in motion and generates the differential speed as a function of bowl speed and gear transmission. The differential speed can easily be regulated by changing the motor speed. Two motor drive are used whenever solid volumes fluctuate significantly, when solids are conveyed under difficult conditions and when particularly stringent requirements are applicable with regard to residual water content.
Hydro drive, it works in a way which is similar to that of the two motor drive. The difference is to be seen in the design.Instead of the mechanical gear, a rotating hydromotor is installed; this is supplied with hydraulic regulation by a pump unit. Because the differential speed is proportionate to the conveyed quantity of oil, automatic regulation can be provided without any problem.
