Environmental TBM Slurry Treatment System developed by KOSUN is the most advanced technolog ical products in the world, which can be widely used in urban rail transit construction, water conservancy and hydropower construction and municipal engineering. In the next 20 years, the construction of domestic infrastructure will be the key fieleds invested by the State. KOSUN TBM Slurry Treatment System can meet the environ mental requirements on urban construction and processing. The market demand of environ mental TBM Slurry Treatment System will be increasing.
KD series TBM Slurry Treatment System is a kind of professional mud treatment equipment developed by KOSUN, which is suitable for purifying slurry in the mud-water balance shield, diaphragm wall, pile foundation and other projects in the process of circulation drilling. It is used to control the mud performance, enhance the quality and efficiency of hole making, support and ensure the safe and smooth operation of roadheading equipment, and improve the recycling of the mud. KOSUN TBM Slurry Treatment System can save construction costs, reduce mud emissions and reduce environmental pollution. It is an economical, efficient and environment-friendly necessary construction equipment.
Ⅱ.APPLICATION OF TBM SLURRY TREATMENT SYSTEM
（1）Slurry balanced shield mud treatment;
（2）Bored pile foundation construction mud treatment (generated by rotary drilling rig, positive and reverse circulation drill and percussion drill during drilling and pore forming);
（3）Underground diaphragm wall construction mud treatment (generated by diaphragm wall and double wheels trench cutter during trenching);
（4）Trenchless construction mud treatment (generated by horizontal directional drilling and slurry pipe jacking).
KD series TBM Slurry Treatment System mainly consists of scalping shaker module, desanding module and desilting module.As a pre-screener, the scalping shaker can remove coarse particles from mud. The desanding module is equipped with desander (primary cyclones) and fine-mesh shaker and mainly removes granulated sand. The desilting module is equipped with desilter (secondary cyclones) and can conduct a fine separation selectively according to the field needs of customers. Mud closed-loop circulating purification mode and lower water content in slags help reduce the environmental pollution. Wear parts of the system are of anti-corrosion and wear-resistance, long service life and low failure rate, and the system can be suitable for various severe working conditions.
(1) Simple and useful treatment process, as well as convenient installation, operation and maintenance;
(2) Modular and integrated design, transportation and installation subject to standard container size, foldable operating platform, compact structure, small footprint and flexible field use;
(3) Adjustable G-force of shale shaker, screen panel angle and mesh size, strong overall system adaptability and easier treatment of materials from various formations;
(4) Meet separation requirements on various materials and customize process as per the cut point of D 50 ; meet the requirements on different handling capacities, 100~3000m³/h;
(5) Meet various power specifications as per construction needs, and even generator set can be used for operation;
(6) The whole system is skid-mounted integrated system and can be also changed into vehicle-mounted mobile treatment units.
