In the tide of urban development, the exploitation of underground space is an indispensable part. In this stage, shield equipment, like a steel dragon, shuttles deep into the stratum, 

playing a crucial role in modern tunnel projects in fields such as underground transportation, water conservancy, and municipal works.

However, while shield equipment is playing its significant role, it has also brought about a new problem: the large 

amount of high-concentration mud produced every day is gradually becoming an environmental nightmare that plagues the engineering community. 

The solid phase in these shield slurry is as high as 20% to 30%. If not handled properly, it will not only clog the shield segments and slow down the construction progress,

 but also may pollute the soil and water sources, posing environmental risks.

Breakthrough weapon: KD Series sludge-water Separation System

The traditional treatment methods for shield slurry mainly rely on physical sedimentation and simple mechanical separation, which have drawbacks such as low efficiency, large land occupation, 

high cost, significant environmental risks, and long treatment cycles.

To solve these problems, improve the efficiency of shield slurry treatment and enhance the environmental friendliness of shield construction, Xi 'an Kosun Machinery Manufacturing Co., Ltd. 

has developed the KD series of sludge-water separation systems. With modular integrated design and multi-stage separation technology, it has constructed a brand-new path to break the deadlock in shield slurry treatment.

The KD series sludge-water separation system integrates three core modules: coarse screening, sand removal, and sludge removal, forming a precise processing chain: 

The coarse screening module first intercepts particles larger than 5cm; The sand removal cyclone combined with the high-frequency vibrating screen removes sand and gravel. 

The desliming cyclone ultimately separates micron-sized particles, achieving a separation efficiency of 98.5%, and the solid content of the tail water is reduced to below 5‰.

The KD series sludge-water separation system is applicable to fields such as slurry treatment for slurry balance shield machines, slurry treatment for bored pile foundation construction,

 slurry treatment for underground continuous wall construction, and slurry treatment for pipe jacking construction. It features a simple and practical processing technology flow, 

and is convenient for installation, maintenance and use. Compact structure, small floor space, and flexible on-site use; 

Selective fine separation can be carried out according to the on-site requirements of customers to meet different processing requirements ranging from 100 to 3000m³/h. 

It can meet various electrical requirements according to construction needs, and even operate with its own generator set. It has the advantages of anti-corrosion and wear resistance, 

long service life, low failure rate, and the ability to be applied to various harsh working conditions.
