Last week, our engineer went to the karachi, pakistan to adjust the decanter centrifuge for clients who are mainly focus on rice protein, according to 2 days commission, adjusting, and training, the users have already well know the decanter centrifuge.


DCLW Series decanter centrifuges provide exceptional performance when separating solids from 1 or 2 liquid phases in one single continuous process. The units are designed to handle a wide range of particles with diameters from 5 mm to a few microns.

With their high efficiency, continuous operation, low capital cost/capacity ratio, low maintenance costs and low energy consumption, the decanter centrifuges are ideal to use in a range of duties including process, food and waste applications.


DC Machinery uses high-grade stainless steel for all parts that come into contact with the process, in order to avoid any risk of the corrosion associated with the use of carbon steel. Corrosion leads to product contamination, lack of balance, high maintenance and lengthy down time.

Following the development and progress of decanter centrifuges. More and more textile enterprise choose the small treating capacity decanter centrifuge used for separate the solid phase in the wastewater.

The solid bowl decanter is a basic, standard machine to which features can be added for special applications. The solid bowl is ideal for clarification of liquids, thickening of sludges, and separation of solids.


Process conditions of the textile field decanter centrifuge:
1. Compact design at high specific throughput
2. Low vibration levels
3. Absolute pressures from 0 to 8 bar
4. -90° C to +200° C
5. CIP cleaning
6. Flameproof or explosion-proof standards making the decanter ideal for applications with solvents and hazardous materials.

The solids dewater by a combination of drainage and compression. The degree of drainage/compression depends on the nature of the solids, the setting of the centrifuge, and the required degree of dewatering. The transport and discharge of pasty, sludge-like or shear-sensitive solids are facilitated by the appropriate combination of conveyor geometry, cone geometry, and control of the differential speed.

Drilling fluid centrifuge is an important part in solid control system. Drilling mud cleaning first stage uses drilling fluids shale shaker ,then second stage uses desander,third desilter,(now drilling mud cleaner is widely used to replace desander,desilter).

As we know, at the beginning centrifuge for drilling rig is from chemical and food industry, etc. But now, we find centrifuge for drilling fluid process is more advanced and professional.

The drilling mud decanter centrifuges can separate fine particles well,for separating 5~7μm particles in drilling mud,usually use medium speed decanter centrifuge,for less then 2μm,usually use high speed decanter centrifuges.

Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently.

Shortly speaking, centrifuges play an important role in the whole mud cleaning system, meanwhile it is an obbligato part for the mud cleaning unit. If you want to learn more about it, please feel free to contact me.

DC Mud equipment company got an new order of decanter centrifuge from Thailand. Now the drilling fluid centrifuge wil delivering to the port.

Drilling mud decanter centrifuge is the fourth stage equipments for a drilling mud system.Drilling mud cleaning first stage uses drilling fluids shale shaker ,then second stage uses desander,third desilter,(now drilling mud cleaner is widely used to replace desander,desilter).

The high-speed, solids control decanter centrifuge removes ultra-fi ne drill solids of greater than 2 to 5 microns at an average process rate of approximately 20 percent of the mud pump flow rate, Anderson continued.

A centrifuge also can be used as a barite recovery system or dewatering system, a practice widely used in the oil and gas industry. The dewatering process, said Anderson, allows up to 100 percent removal of all suspended solids from the drilling fluid. The reclaimed water can be used to make up new mud for another job or as rig wash-down water.

DC Machinery is a professional manufacturer of all kinds of decanter centrifuges. We can provide many different fields used centrifuges, such as oil and gas, food, chemical and mine well industry. Below is a introductuion of the full hydraulic drive decanter centrifuge.

A centrifuge with hydraulic drive is an interesting object from the fluid dynamics point of view. To achieve high efficiency, the hydraulic resistance of the inner, quickly rotating with the rotor, passages should be minimised.

At the same time the fluid should pass through an area far away from the axis of rotation, where the centrifugal force is greater. Nozzle efficiency is crucial. The air in the gap between the rotor and the centrifuge cover also moves, and the air friction makes a
significant contribution. Jets from the nozzles might break down into a fine spray and hit the rotor, slowing it down. Optimizing such a device is quite a challenging task, but this can, indeed, be done.

The hydraulic bowl and scroll drive system drives both the conveyor and bowl of a decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits.

The advantage of the full hydraulic drive centrifuge is for use in high temperature ambient for heavy mud with flexible bowl and differential speed. The compact one skid design makes it easier for rig up.

A wastewater centrifuge from DC Machinery can provide the perfect solution for your sludge dewatering needs. The centrifuge can remove the water content from sludge by rotating it at a high speed, so you can dispose of the sludge in a cost-efficient manner. After the centrifuge has completed its process, you will simply need to collect the dry sludge and send it to a landfill.

The Decanter centrifuge can be used for the pre-treatment for the algae biomass for the disk separator or tubular separator thus it effective higher the disk centrifuge or tubular separator capacity performance .

The decanter centrifuge is a horizontal centrifuge with continuous feeding and continuous discharging. The settling speed is determined by particle size, particle shape, difference in density between solids and liquids as well as their viscosity.


Decanter centrifuge is a separation equipment used in many fields, such as, oil& gas, HDD, all kinds of wastewater treatment. In the begining of 2016. DC Solid control got an order of decanter centrifuge used in oilfield from Nigeria.
