The KD-425 Slurry Treatment System consists of scalping shaker module, desanding module and desilting module. Equipped with coarse-mesh screens, the scalping shaker module is used to remove big particles. The desanding module is equipped with two desanding cyclones, and the desilting module is equipped with six desilting cyclones, and a dual-deck shaker is used as the underflow shaker for desander and desilter respectively.

The mud falls into the collecting box via scalping shaker, and then is conveyed to the desanding module through a connecting trough. The desanding module is equipped with a desander having two 18” cyclones in diameter and is capable to remove sand from the mud. The desilter with six 6” cyclones in diameter can further separate the mud as required.

6 Tips of Decanter Centrifuge Safety Operation Regulation

Just as we all know that Decanter Centrifuge is one kind of machine revolving at high speed. During operation, revolving drum will generate strong centrifugal force (it is not like the solid control system, to some extent, decanter centrifuge is a core part for a whole solid control system and water based mud unit). To ensure the safety of operators and equipment, the following safety rules shall be strictly followed when using it.

  1. Pay more attention for original Instruction Orders or Steps. Through dynamic balance of revolving drum parts of centrifuge, during assembly, original installation order shall not be changed and there shall be no parts omitted. Threaded connection part shall be installed in place; during assembly, if there is assembly mark, the mark shall be aligned. Before startup, operating pump system shall be inspected and there shall be no water leakage under close state of magnetic valve.
  2. Keep the decanter centrifuge off. Before clamping revolving drum clamp ring and fixing inlet/outlet device and other fastening screws, decanter centrifuge shall not be started.
  3. Before completely stopping revolving drum, any part of equipment shall not be loosened.
  4. During operation, if abnormal vibration of decanter centrifuge is found, power shall be cut off for emergency shutdown. After revolving drum is completely stopped, each part shall be disassembled cleaned and inspected and attention shall be paid to assembly order and position. After the causes of abnormal vibration are found out and removed, reassembly and startup can be carried out. Time interval between re-startup and shutdown shall be more than 4h (This item is also suitable for mud cleaner).
  5. Flame heating or repair welding of main revolving drum parts is not allowed, especially revolving drum body, revolving drum cover and clamp ring.
  6. Use of revolving drum parts and revolving drum parts of other equipment shall not be mixed, even the revolving drum parts with same model.

The above 6 tips or we can call it as steps should be kept in our mind, they can help us improve our working efficiency. Just as I mentioned in the post, you could find more information about solids control systemdrilling waste management unit, oil recovery unit, and some other solids control equipment, such as mud cleaner, sand pump, vacuum degasser, cutting dryer, etc. In another words, KOSUN could be your better cooperator.

Industry Information about Decanter centrifuges for sale

Decanter centrifuges for sale utilize centrifugal force to speed the dewatering or thickening of slurries and suspensions in many industrial and commercial applications. While these centrifuges, like others, may also be used to separate liquids from liquids, they are more applicable in situations that require the separation of liquids from appreciable amounts of suspended solids.

decanter centrifuge for sale

Food and beverage, water treatment, oil, gas and pharmaceutical industries commonly employ decanter centrifuges for the classification of solids based on the sedimentation principle as well as the clarification of fluids resulting from the settling out of debris. Other industrial uses for decantation include solids recovery which enables many manufacturing facilities to recover and reuse valuable materials that would otherwise be disposed of along with wastewater.

While gravity alone is sometimes used, decanter centrifuges are essential in applications where the density difference of elements within a heterogeneous mixture is too small or the particles themselves are too small. Whereas normal gravity could take ages to sort these materials, the centrifugal force generated by industrial centrifuges speeds the process while producing drier solids. Dryness is important as both dewatering and drying materials helps to provide raw or processed substances that are lighter in weight than their immersed counterparts making for easier handling and lower transportation costs.

The operation of a decanter centrifuge can be either batch or continuous and is not altogether dissimilar to other types of centrifuges. A metal or plastic cylinder fixed along a central axis houses the materials or solutions to be sorted. When a motor engages the axis perpendicular to this, it creates a rotational movement capable of creating gravitational pulls up to twenty thousand times that of normal gravity. This causes larger particles to separate out first in a radial direction allowing them to move toward the bottom of the cylinder while lighter materials move toward the top.

In some decanter centrifuges a mesh is used to collect solids with liquids passing through to the outer area of the cylinder before being drained. In other models a helical extraction screw directs solids to one end and liquids to the other. If high enough acceleration is reached, the solids may even become compressed for easy removal. Both new and used centrifuges are available to purchase. As adjustable and fixed acceleration models are widely available, it is important to consider the parameters of a specific application before purchasing a decanter centrifuge. Capacity should also be considered with regard to the intended use as should the design and material construct of a decanter centrifuge as these materials must be compatible with both process liquids and solids to be sorted.

Features of KOSUN Decanter Centrifuge for sale

Solids control equipment decanter centrifuge is one stage of solids control system.Normally solid control system is consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, decanter centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as Hi-volume mud cleaner. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air in the mud, the degasser would work as a big agitator. All these equipments are mounted on the top of the mud tank. Decanter centrifuge is used in separating suspension of solid phase with particle diameter d>=2um for drilling mud and fluids handing. After separating the solids, the mud would be pumped into the borehole again.
