mud cleaner

Desander, desilter and mud cleaner is the most common type hydraucyclone separator machine used in mud cleaning system, like system for oil and gas drilling, water well drilling, Geothermal drilling, Coal Bed Methane drilling, Horizontal Directional drilling and so on.

Hydraucyclone separator desander desilter and mud cleaner is used after shale shaker, and then dessander, desilter is used after desilter. Per the jobsite condition and the mud drilling rig request on mud, only desander or destiler separator can be used, or none of them be used.

There are different type of hydraucyclone separator. They have different features, users can choose the suitable model.

Design 1: Only Desander or desilter hydraucyclone assembly, without underflow shale shaker.

Option models for desander: GNWSE-2S / GNWSE-3S

Option models for desilter: GNWSE-12N / GNWSE-16N

Strong point: The simple type desander and desilter is with side-discharge deisng. It is with small footprint. And price lower.

Weak point: Hydraucyclone is not D100 separator. If there is no shale shaker separator under the hydraucyclone parts, performance will not be very good. Some big size solids may flows into the tank mud system.  

Conclusion: If there are limited space on tank top and users want to save cost. desander and desilter without underflow shale shaker should be a good choice. It is normally used is underground construction system and compact mud system but not used for deep oil and gas drilling.

Design 2: Desander desilter with a small size under flow shale shaker.

Option models for desander: GNZJ752E-1S / GNZJ752E-2S

Option models for desilter: GNZJ752E-8N / GNZJ752E-12N

Strong point: With separate shale shaker under the hydraucyclone assembly, drilling fluids can be separated by screens before falling into tank system. And price is good.

Weak point: The small size shale shaker cannot get very good separation result, and big capacity not available.

Conclusion: It is normally used in compact mud system for HDD, CBM etc… And some workover rig mud system.

Design 3: Desander desilter with a big size under flow shale shaker. Both desander and desilter hydraucyclones can be mounted in the same shale shaker. Compact design and best separation. The price the most high among the 3 designs and performance best. When move the hydraucyclone assembly . It can be used as a separate solids control shale shaker.

Above is the introduction of the models, users can choose the suitable design per its detailed condition.

Double deck shale shaker is widely used in CBM drilling (Coal bed methane), piling, micro tunneling and other HDD rig mud system as its big capacity and compact design. The top deck shaker screen can use steel screen (0.1mm, 0.2mm, 1mm etc… per jobsite condition) to separate the coarse size. The bottom deck use normal pretensioned frame screen (API40, 60, 80 etc…)

4) Patent tighten rubber sealing for shale shaker deck and screen. It is with long life and easy for replacement.

5) Pretensioned shale shaker screen mounted with wedge for fast screen change.

6)  Flexible options on feeding type: Weir Feed, Top Feed, and Hopper Feed for different applications

7) The shale shaker can be mounted together with desander cone and used as a mud cleaner.

General description of Hydraucyclone desander desitler

Hydraucyclone is a normal parts used for mining industry, for drilling field, for waste water separation, soil depuration. In drilling field. Hydraucyclone can be used as desander desilter per different size. Or combined with shale shaker to work as mud cleaner. 

Big size desander cone normally used for mining, piling or CBM drilling.  Hydraucyclone for desander desilter in drilling fieldi usually small size:

1) Hydraucyclone for desander: 12inch, 10inch

2) Hydraucyclone for desilter: 5inch, 4inch

Main parts of Hydraucyclone for desander desitler. Take example of 4 inch desilter cone, it is components of below parts:

1) Shell

2) Cone tube

3) Drop in Apex

4) Orifice nut

When combined for a desilter machine, elbows and clamps, ball valves will be used for connection.

Principle of Hydraucyclone for desander desitler

Hydrocyclone is a cylindrical part of the conical vessel. The upper part of the internal cone section called the liquid cavity. Cone outside is provided with a liquid inlet pipe, and the liquid cavity is communicated to the tangential direction. The top of the container is the overflow port, the bottom is underflow (also called the discharging port). Cyclone size is determined by the maximum diameter of the cone. Its working principle is centrifugal sedimentation. Because of the coarse particles and fine particle size difference exists (or density difference), the centrifugal force, under the centripetal buoyancy, drag force of different sizes, due to the centrifugal sedimentation, pyramidal intermediate creates a low pressure area, forming a column of air, caused by vacuum suction effect, play, most of the fine particles in the cyclone under the actions of upper discharged from the overflow tube, heavy particles thrown to the wall of the barrel, slide along the barrel wall, from bottom outlet.

Materials ofd Hydraucyclone for desander desitler

Polyurethane is also called polyurethane formate, is a kind of polymer between the plastic and the rubber polymer materials. It has not only high strength plastic, and has the high elasticity of rubber. It is a new type of wear resistant material, an excellent comprehensive performance. It has many excellent performance, high wear resistance, in the synthetic material of the first, even more than some alloy steels. The polyurethane as hydrocyclone lining, its service life is four times of high chromium cast iron, four times eight times Ding hydrogen rubber, natural rubber. Polyurethane shore hardness in the range of 17~97 to 85~90, the best wear resistance.

HDD means horizontal directional drilling. Many people are wondering when HDD machine used? You see, you want to put pileline undergoud pipeline, but there is a huge river in the area. How did you do, to full up the river or change direct to pass it? No, it is huge work. With HDD machine, you can put pipes in a depth first, and then cross pipes under the river. Another condition like that, it requests to put some underground pipes for cable, for water, for natural gas, etc… in city area, but it is not possible to dig up the ground, there are buildings and constructed road on it. With HDD machine, things will be very easy.

80T HDD machine is a most common side drilling rig. The high pressure is between 1000 to 2000 liters. 350~500GPM mud system is used for this rig size.

For different customer and different rules for discharge, there are different standard mud system.

If your 80T machine is for HDD, we recommend you GN350~500 GPM mud system.
