TBM Slurry System Good Performance by Kosun Manufacturer

TBM Slury System

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.

Shake shakers are the first group of equipment used in the system. They help to remove huge cuttings or solids from the mud or drilling fluids. These are types of mud separators used not only in the oil industry but in mining, and coal cleaning industry. The shale shakers are the basic separation tool found on the rig. When the drilling fluids get to the surface, they are passed into the shale shakers for onward processing.

Many people in the drilling industry would refer to them as the most important equipment in the industry, so as the shaft sinking projections. There are two types of shale shakers, the primary and the secondary. The primary shale shaker make use of coarse screens to remove larger cuttings while the secondary shakers uses fine screens to separate smaller cuttings.

When you bring the functionality of desanders and desilters in one, what you have is the mud cleaner because they function to remove the drilled cuttings from the mud. There are yet many other types of the mud separation systems, including desilters, desanders,mud agitator, mud guns and mud pumps.

And maybe another type of machines can be used(but not often), mud gas separator,This system is often referred to as the gas buster. It engulfs large amounts of free gas within the fluid in the drilling channel. The process it goes simply by introducing the mixture of mud and gas into the system. With impacts with a series of baffles installed, the mixture is then separated accordingly. There are three types of the mud gas separator. They are :Open bottom type,Closed bottom type and Float bottom type.
