Decanter centrifuge is also a major component on the mud separation system, its a device that helps separate the finest silt and sand from the drilling fluid. The centripetal acceleration on a centrifuge causes the substances and particles that are denser to move outwards in the radial direction. A mud tank is used for storing drilling fluid on a drilling rig, it also works as the base for the solids control equipment. Mud tanks are a vital component on a mud separation unit.

A desander and desilter are also for mud separation on oil rigs. They are a couple of hydrocyclones that deal with the separation of silt and sand from the drilling fluids found in drilling rigs. Desanders are usually located right on top of a mud tank and they will be followed by the degasser and the shale shakers . The vacuum degasser is also a necessary component on an oil based mud separation system, its purpose is the removal of gas from drilling fluids as this might cause the formation of bubbles.

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.

Trench Cutter Separation Units or AVN Machines Separation Units by Kosun

Trench Cutter Separation Units

Trench cutter separation units or AVN Machines separation units they are different application area of the mud separation in nowadays, but they share a common point, that they all belong to the recycling and cleaning management of the slurry in projections.

Trench cutter separation units
Trench cutter separation units

Trench cutter separation units or AVN Machines separation units are widely used all over the world. The main use of this kind of treatment method is for the purpose of clearing all the solid waste and impurities from the water and making it reusable. In slurry treatment method, shield method is used for the purpose of construction of the tunnel in which the water will be passed. The water which will consists of all the impurities and semi-fluid waste will then be properly treated to provide the user with a refined product.

There are many different processes which are required for the purpose of AVN Machines separation units or trench cutter separation units. One of the process which is required for slurry treatment is use of vibrating screen. Vibrating screen which make sure that the water will get dehydrated and all the solid waste which is mostly in the form of mud will get separated from the water. Next equipment which is used for the purpose of Slurry Treatment is filter press. In this equipment the mud which is obtained will be pressurized and dehydrated so that the solid and liquid waste can be separated.

AVN Machines separation units

Next important element in the AVN Machines separation units or trench cutter separation units is the agitating tank. This tank consists of all the mud which get produced during the process of construction with the help of agitator. The agitator in the tank prevents any kind of deposition of solids.

This is a very important step as it can ensure that you get the best prevention from any kind of damage. Next and the final equipment used in the Slurry Treatment is the water waste treatment device which can make sure that proper pH level of the water s adjusted. This will clear out all the mud from the water and leave very clean and pure water for further treatment. Slurry water treatment can be very effective in
ensuring that you get best quality water.

Shaft Sinking Machines Separation Units by Kosun

Shaft Sinking Machines separation units

Shaft sinking machines separation units,also can be called by Kosun Shaft Sinking Machines separation plants or Shaft Sinking Machines separation stations, is refered to the slurry separation or mud cleaning machine system in shaft sinking progress.

Shaft Sinking Machines separation units have several components, and they are: Shale shakers, Desanders, Desilters, Mud tank, Mud pump(or screw pump), and electric control panel and other accessories.

Shaft Sinking Machines separation units

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.

In one word, the Separation units in shaft sinking machines used projects are important and should be pay more attention.
