Horizontal decanter centrifuge is driven by two motors. The main motor drives the drum and the housing of the differential through the belt, and the auxiliary motor drives the auger after the differential speed.This will cause the drum and the auger to rotate in the same direction with a certain differential.
Drilling operations refers to the very process of extracting oil and gas from the earth for various commercial and industrial purposes. The industry is worth trillions of dollars today and is thus a very important part of any country’s development. In the past few decades, the demand for the products like gas and oil went up significantly. This led to a corresponding increase in the drilling activities all across the globe.
Like any other industrial activity, drilling too is bound to have some sort of waste produced as byproduct. This is termed as drilling waste and the term gained much popularity with the rising issues it caused to the environment. This in turn led to another class of waste management being introduced, known as drilling waste management . It involves several processes from maintenance, management and containment to subsequent handling and disposal of drilling waste promising better sustainability and conservation of environment.
In the various processes involves with drilling waste management , one important step is called waste maintenance. This was earlier done with conventional processes like settling and involves separation of the unwanted matter from the desired part and further storage and transportation. However, with advancements in technology and machinery, today the whole process id mechanized. The most popular equipment dedicated for the process is named decanter centrifuge .
As the name suggests, the machine uses centrifugal force to aid to the separation of waste matter. The machinery has a complicated design but with a very basic and simple concept. The mixed substance obtained directly from extraction is allowed to flow to a disc shaped structure. The disc is then rotated. This rotation calls the centrifugal and gravitational forces into action which facilitates the separation of drilling waste from the fuel. The fuel passes through the hole at the centre of the disk and the waste remaining in the structure is passed on for containment.
The equipment consists of moving parts and hence should be cleaned and kept smooth as possible to avoid reduction in efficiency. Also make sure to cut off the power to the machinery if it is to be dismantled for some purposes.
Drilling Decanter Centrifuge that is a machine based on centrifugal operation to separate different components is called a centrifuge. Which is welcomed by domestic and foreign customers.
A settling centrifuge is a special type of centrifuge that separates solid components from liquids such as drilling waste . Centrifugal force is the force that the object experiences when rotating at high speed. They are commonly used to separate components of different densities, such as water and solids.
Sedimentation centrifuges play an important role in wastewater treatment, chemical and food processing. The performance of the settling centrifuge depends on several different factors.
Most of the drilling and treatment plants deal with the mixture of components. They must be separated for further processing.
The main three types of settling centrifuges are used in industry:
The settling centrifuge is essentially a bowl that is rotated at high speed to separate solids from the liquid matrix. In the case of a drilling industry, the input is a drilling waste .
Centrifuge is very easy to install and requires less maintenance. Even if skilled operators need to operate them, the decanter centrifuges help save a lot of money and improves the overall efficiency of the industry.
Centrifuge provides more flexibility and better feedback mechanisms. This allows the operator to allow the machine to work under different settings to separate the different parts. The space required to install the machine is very small, easy to start or shut down, allowing multiple units to work at once.
Decanter centrifuge is not without restrictions. The machine will produce a lot of noise and vibration. It can not separate biological components and has high energy consumption. The initial cost of setting up the machine is quite high. The rotating parts are also prone to wear and tear over time.
A machine which operates on the basis of centrifugal force to separate out different components is called a centrifuge. Centrifugal force is the force experienced by a body when it is rotated at high speed. They are normally used to separate out components of different densities such as water and solids. A decanter centrifuge is a special type of centrifuge that separates out solid components from liquids such as drilling waste.
Decanter centrifuge plays an important part in the process of wastewater treatment, chemical industries and food processors. The performance of a decanter centrifuge depends on several different factors.
Most of the drilling and treatment plants deal with a mixture of components. It is imperative to have them separated out for further treatment. Mainly three types of decanter centrifuges are employed in the industries: horizontal, vertical and conveyor. A decanter centrifuge is essentially a bowl that is rotated at high speeds to separate out solids from liquid base. In case of drilling industry the input is drilling waste.
Centrifuges are quite easy to install and require less maintenance. Even though skilled operators are required to operate them, decanter centrifuges helps in saving a lot of money and increases the overall efficiency of an industry. Centrifuges offer more flexibility and better feedback mechanism. This allows the operators to allow the machine to work at different settings to separate out different components. The space required for setting up the machine is very small and easy to start up or shut down, allowing more than one unit to work at a time.
Decanter centrifuges are also not without its limitations. The machines cause a lot of noise and vibration. It cannot separate biological components and has high energy consumption. The initial cost for setting up the machine is quite high. The rotating parts are also liable to wear and tear over time.
Now building on this definition, we can imagine the vast application of such equipment in a variety of industrial scenarios, where different materials need to be separated. Let us pick oilfield drilling industry for an instance, where large volume of drilling waste is produced by the drilling process.
Not only the waste is harmful to the environment, if disposed directly without treatment, but it also contains large quantity of drilling fluid that needs to be extracted and restored. To accomplish this challenging task of separating the fluid, decanter centrifuges are deployed in drilling operations.
The working of a centrifuge could be understood as – If laid down in plain words – it uses the express rotation to separate different types of materials. In a more technical expression, a centrifuge is the equipment that uses the centrifugal force to separate substance based on their density using the principle of sedimentation.
Imagine a jar full of milk cream, when churned at good speed, it separates the cream into butter and skimmed milk. We know that different materials have different density, and the centrifugal force makes them move against the axis of the pit in which they are stored with the help of rapid rotations using mechanical force. Naturally the material with lowest density will make it way upward and the one with highest density will get settled at the bottom of the pit.
The decanter centrifuge equipment is used in a variety of machines that need to filter the mixture of solids and fluids. It finds it application in number of industries ranging from food processing industry to oil and natural gas industry.
Drilling Decanter Centrifuge is a device used in separating suspension of solids for drilling purpose. It has been designed for Oilfields and Industrial purposes that are seeking an environment friendly solution. Its speed ranges from 0n to 3900 RPM, generating centrifugal forces reach up to 3000G.

Drilling decanter centrifuge is equipment used to separate solids and fluid from a mixture using centrifugal force. Centrifugal force is a force, arising from the body’s inertia.
Drilling Decanter centrifuge technique replaces the conventional method of settling down the solids in the process of water treatment and likes. The technique makes the process faster and improves the quality of the output at the same time.
The drilling waste largely consists of drill cuttings and drilling fluids that are commonly called as drilling mud. Drilling cuttings are nothing but the rock shavings acquired during the borehole drilling process and the drilling mud is a mixture of chemicals that aids the drilling process by keeping the drilling bit cool and lubricated during the process of drilling.
Other than petrochemical industry the Decanter centrifuge has its application in number of other industries as well, e.g. food processing, waste water treatment, fish processing, chemical, mineral processing, organic chemicals, polymer and inorganic chemical industry to name a few.
Due to its wide popularity across different industries, a decanter centrifuge is available in various types and variety of designs. A few notable ones being – vertical orientation, horizontal orientation and conveyer or scroll type. Operators will be using their discretion to choose the appropriate type and design as per the application need, as that remains customizable.
The performance of same design and type of decanter centrifuge may also differ in two industries, as the performance will largely depend upon number of external factors, chief among them will be the type of the waste material they will be treating with. As the guiding principle of a centrifuge is the separation of fluid by buoyancy of the material it works on to separate.
