Effect of decanter centrifuge on waste mud treatment

Jun 25, 2020

All along, the treatment of waste mud is a relatively complex problem. This is because the composition of waste mud is complex, which contains a large amount of clay, sand, gravel soil, weathered rock, minerals and cuttings, etc. It has a high consistency and can not be directly discharged and difficult to settle naturally. Next, we will analyze the treatment effect of the drilling mud by the decanter centrifuge.

It should be known that if these slurries are not treated in time, it will not only affect the construction on site, but also cause environmental pollution or water pollution. So, what is the processing effect of the decanter centrifuge? The traditional processing methods adopted in the past always have some disadvantages. After using the equipment, the dewatered mud can improve the dryness of the sediment and reduce the volume, which can be used as greening backfill soil for transportation or brick making.

More importantly, after being processed by a decanter centrifuge, it can significantly reduce the transportation and discharge costs of mud. Moreover, after the separation process of the equipment, the solid content in the liquid has greatly decreased, and it can be returned to the mud tank, and the mud concentration can be adjusted at any time, which is conducive to improving the drilling speed and the quality of hole formation.

Based on the analysis of the above processing effects, it can be seen that the decanter centrifuge is actually a new type of high-efficiency and energy-saving solid-liquid separation mechanical equipment. Usually the equipment is mainly composed of rotating drum, screw feeder, differential and power, and main parts of the frame.

Compared with other treatment methods, the advantages of the decanter centrifuge are obvious:
1. The device itself has a compact structure, and the machine has small volume and light weight under the same processing capacity, and it is relatively convenient to move;
2. Large processing capacity, good separation performance and wide application range;
3. High solid phase recovery rate, low operating cost, no filter cloth;
4. Automatic continuous operation, simple operation and use.
