Decanter centrifuges are used to dewater tailings to eliminate sedimentation ponds, for better disposal, to recycle water or to meet environmental regulations.
Uses of Decanters
Decanters have various uses including separating liquids and solids. One of these uses is in the aggregate process, where they are utilized to treat tailings found in the waste stream.
Decanters remove particles from the liquid waste streams generated by wet processing plants by using strong centrifugal forces to produce sedimentation. Decanters produce two materials: a solid cake suitable for mechanical handling and a liquid that can be reused as upstream process water.
Decanters use powerful centrifugal forces to separate particles from liquid waste streams in wet processing plants, resulting in two materials – a solid cake for easy handling and a reusable liquid for upstream processing water.
A decanter offers a major benefit when it comes to treating tailings as it streamlines the waste treatment process. This method can potentially eliminate the need for lagoons or sedimentation ponds at certain locations, saving both time and money in maintenance costs.
Components of a Decanter Centrifuge
The decanter centrifuge is comprised of important components, including a feed pipe, screw conveyor, and bowl within a housing for simple maintenance and reduced noise levels. The collected discharge is directed through a chute. Not only is the decanter centrifuge reliable, but it also offers easy maintenance and quiet operation. Featuring a feed pipe, screw conveyor, and bowl within a housing, this product ensures smooth and efficient processes.
Working Principle of Decanter Centrifuge
A decanter is a closed settling tank with a shaft that separates liquid and solid particles by centrifugal acceleration. Denser solid particles sink to the bottom, forming a sediment, while lighter liquids move outwards due to centrifugal force. Our decanter uses advanced separation technology. With its innovative design, it can effectively separate liquid and solid particles and easily collect the sediment. Say goodbye to cumbersome filtering processes and get faster and more effective results.
Decanter centrifuges use centrifugal force to separate liquids and solids. The slurry enters the screw conveyor through the feed pipe. The slurry then enters the area between the drum and the rotating conveyor. The solids in the slurry move the drum wall and the liquid moves to the discharge end of the device.
The feeding, separation and unloading processes of the decanter centrifuge are carried out continuously and automatically at full speed. The equipment control can communicate with the microcomputer according to user requirements to realize process automation control, reduce manual intervention and improve production efficiency.
Optimizing Decanters
In order to optimize a decanter centrifuge, it is necessary to consider the desired site goals. This may involve producing a clearer liquid or a product with drier solids. To achieve drier solids, certain adjustments can be made.
- Increase unit speed
- Change feed location near the liquid end of the bowl
If the objective is to enhance the transparency of the liquid, the following modifications could be implemented:
- Increase pool depth
- Increase speed
- Decrease feed rate
- Add chemicals to enhance settling
