KOSUN KD-250 Microtunnelling Sludge Separation System Successfully Applied in Poland

In 2019, KOSUN completed the production and commissioning of a set of KD-250 Excavator-Mounted Integrated Environmental Microtunnelling Sludge Separation System and shipped them to Poland for a sludge separation project in micro-tunnel construction.
This set of equipment has been successfully applied in Poland and has received praise from the customer.

The KOSUN KD-250 Excavator-Mounted Integrated Environmental Microtunnelling Sludge Separation System adopts a modular structural design, consisting of a shale shaker, a decanter centrifuge, a cone tank, and a cloth distributor. The slurry enters the screening system through the cloth distributor. After step-by-step processing by the coarse screen of the shale shaker, the decanter centrifuge, and the fine screen of the shale shaker, it can effectively separate the sand and stones carried in the slurry. It can remove larger solid particles from the tailings, reduce the solid content in the mud, and the slurry processed by the system can enter the next-level processing equipment such as a centrifuge or a filter press.

The shale shaker used in this system is the double-layer linear shale shaker LS-608 series. The main components include the screen box assembly, the shaft seat, the handwheel lifting device, the adjusting beam assembly, and the locking device assembly, etc. KOSUN LS-608 is a linear vibration machine equipped with two vibration motors, featuring the ability to adjust the screen frame angle. During the operation of the shale shaker, the screen frame angle can be adjusted between -1° to +5°. Thanks to the innovative structural design, the KOSUN LS608 shale shaker can efficiently separate solid particles in the slurry. The vibration motors are fixed and positioned on the screen frame with high-strength support beams, and this positioning of the vibration motors allows the exciting force (G-force) to act directly on the screen panel. The vibration isolation device can protect the base frame from the impact of screen frame vibration.

KOSUN has accumulated rich experience in the development of environmental sludge treatment and has numerous on-site application cases at home and abroad. For more information on environmental sludge treatment equipment, please feel free to contact us at any time.

Subway mud management and separation process

Mentioned the subway mud management and separation equipment, we should first understand the classification of shield machine.

一, the classification of shield machine.

(1) According to if the excavation face is closed:

Closed 2. Open

(2) according to the different principle of balanced excavation surface earth pressure and water pressure:

Closed shield machine can be divided into:
earth pressure type B. mud type
Open shield machine is divided into:
hand-digging B. semi-mechanical digging C. mechanical digging.

二, the subway Subway mud management and separation process:

Mud-water balance shield machine is a device for mud-water separation in the shield. The mud is used to resist the water pressure, and earth pressure on the excavation face to keep the stability of the excavation face, and control the deformation of the excavation face and the foundation settlement. The mud film is formed on the excavation face to keep the water pressure effectively acting on the excavation face.

The management and separation process of KOSUN KD Series mud management system:

(1) Separation of most solid stones and clods by primary screening;

(2) After the first stage is separated, most of the large particles above 3mm are separated, the separated mud flows to the slurry tank, and then is pumped by the mud pump to the secondary cyclone for separation;

(3) The accuracy of secondary separation is in the range of 70-74μm. After the secondary separation, the slurry is again pumped to a three-stage flow separator for separation.

(4) Three-stage cyclone separation accuracy is in the range of 20 ~ 25μm, three separate mud flow back to the pulp pool;

(5) After the waste slurry is subjected to pressure-dependent separation by a filter press as required, the mud particles larger than 5 μm in the slurry are almost completely separated, and then the precipitate is discharged to meet the emission requirements. Through these 5 steps the mud particles and water are separated.(Editor:Kosun Lily.Wang)

Tunnel Boring Machine Slurry System of Kosun on Soft Ground

Tunnel Boring Machine Slurry System

Tunnel Boring Machine Slurry System of Kosun with more than 20 years experience.
Three main types of tunnel boring machine separators are used in soft ground excavations-
–   Slurry shield TBMs
–   Earth pressure balance machine
–   Open – face type
In soft grounds with pressure less than 7bar, earth pressure balance machines are used. These along with cutting head also comprises tungsten carbide disc cutters, cutting bits and hard disk cutters.

Machine derives its name from the fact that it balances the pressure in tunnel head by use of excavated earth. Rate of excavation and advances through Archimedes screw controls pressure in the cutterhead. Some additives like bentonite may have to be injected to increase the stability.

Kosun Tunnel Boring Machine Slurry System — Tunnel Boring Machine Slurry System

These are also added to make sure that the earth is sufficiently attached to the Archimedes screw thus marinating the pressure in the head and prevent seepage of water in the tunnel.

Slurry shield TMBs are used in cases where the ground is so granular in nature that it cannot form plug in Archimedes screw. The cutting head is feeded with slurry which in turn applies pressure. This even acts as transporting medium as it mixes with excavated earth and is being pumped out in slurry separation units usually located out of tunnel. In this separation unit slurry is processed so that it is recycled and can be used again. This filtration is a multi- staged process. However, filtration of slurry depends on the size of excavated particles.

Thus making this slurry shield tunnel boring machine separation units suit able for clays and silts sized particles as they are smaller than bentonite particle, which makes the slurry. In these instances separation with water can be done which will help form clay cake thus filtering the slurry in the end.

In grounds where the excavated tunnels can stand without support for a little period, open face TMBs can be used. These tunnel boring machine separators are generally used where strength is more than 10Mpa and seepage of water is low. Cross sections of sizes up to 10 meters can excavated with these TMBs.

Cutter head excavates within 150mm of the shield edge. This shield is moved forwards and cut the ground in same circular manner. Pre-casted concretes or graphite iron segments provide ground support. The key spreads the rings until it is tightly fitted against the tunnel made by tunnel boring machine separators shields. Open face TMBs comes in many variations.
