Tunnel Boring Machine Slurry Separation System is the role of the shield of sand formed by the formation of sludge for particle separation and treatment, and then the recovery of mud into the adjustment tank.
In general, in the shield of the mud separation system using shaker as a primary separation is more appropriate, the role of the vibrating screen is the pretreatment of mud, remove the ball and block and other coarse particles.
TBM Slurry Separation System in Sweep Slurry Separation System. As long as the function is to refine the fine granules after further separation, the sludge particle size is reduced, and the TBM Mud system is generally treated with multi-stage cyclone.
The working principle of the cyclone in the shield mud-water separation system is based on the centrifugal force generated by the high-speed rotation of the hydrodynamic force.
The cyclone pump causes the cyclone to generate negative pressure during the rotation, forcing the fine particles suspended in the cyclone. Through the centrifugal effect of a spiral rise, through the overflow was negative pressure extrusion, coarse particles in the slurry under the action of their own gravity into the underflow to the pulp tank.
TBM Slurry System in the different diameter and diameter ratio and different working pressure, will play a different treatment effect.

TBM Slurry system construction machine has a high degree of automation, saving manpower, construction speed, opening, climate, excavation ground subsidence.
TBM slurry system can control, reduce the impact of buildings on the ground and digging water does not affect the transport characteristics of water, Long tunnel hole on the line, the depth of large, with shield machine construction more economical and reasonable.
TBM separation and drilling and blasting are being used for construction of tunnels. Drilling and blasting uses various explosives or gas pressure blasting for breaking the rock to be excavated.
Before the practice of Tunnel boring machine separation use drilling and blasting was the most economical ways to make tunnels through hard rocks. Even till date drilling is practiced in some places. The decision as to which mechanism for making tunnel is to be used depends on the length of the tunnel.
Cost of TBMs is high but due to their fast rate of penetration and less man power necessity, per meter cost in long tunnel is comparatively very less. Even the condition of ground has to be taken into consideration as to which mechanism is to be used. TBM separation system have several advantages over drilling and blasting as–
– Excavation speed – Main advantage of TBMs is its speed. Their speed though depends on various factor is up to 100-150 meters per day in favorable conditions. In Norway these had reportedly excavated the rate of 300 meters in very extreme conditions.
– Ventilation is better in the tunnels made
– Its circular profile helps long term stability
– Safety of workers is assured; at first within the tunnel boring machine separation and later by traditional support mechanisms
– Improved working conditions for workers- highly mechanized tunnel boring machine separation help the worker thus less intensive work has to be performed by them.
– Simplified disposal- as the cutting are of similar sizes, their disposal to the surface is much easier.
Due to this tunnel boring machine separation are cost effective and efficient in long drive tunnels with straight opening underground for workers. They cost one third of the cost of drilling and blasting and greatly decreased construction time.
TBM Slurry Separation System is the new pulp and adjust the pulp through the pump and pipeline to the shield excavation surface. Cutter cut down the dry soil and water to be mixed into the mud, through the pump and pipe will be mud to the ground to the ground shield water separation system to adjust.
TBM mud system is mainly composed of pump piping and supporting parts and so on, through the shield mud separation system mud water monitoring system for automated operation.
TBM Slurry Separation System can provide excavation mud for excavation construction in a timely manner to the excavation surface. The technical index of mud with high quality bentonite must meet the requirements of forming mud and stable excavation in high permeable sand Claim.
In addition, the TBM Slurry System can promptly cut the sand formed by cutting the soil to the ground for separation and treatment, and then adjust the use of recycled mud.
TBM Slurry Separation System is to cut down the soil sand formed mud, through the fluid output. Separated by sand and water, and finally the sand will be abandoned to recover the mud pump into the adjustment tank processing system.
According to different classification TBM mud treatment system shield excavation method can be divided into: open, mechanical cutting, grid, TBM MUD separation equipment and extrusion and so on.In order to reduce the formation of shield construction disturbances, HDD / CBM / TBM drilling mud recovery system can be through the jack shield to cut through the soil, and then in the incision excavation and transportation.
TBM Slurry Separation System of Kosun gain well recognized by clients all over the world because of its high quality and best after service sales. Welcome to contact us if you need.
