Drilling fluid cleaner also means mud cleaner, or drilling mud cleaner, and the cones, hydro-cyclone cones is the main part of the drilling fluid cleaner.

Drilling fluid cleaner (mud cleaner) is a combination of desander,  desilter and shale shaker,  and the differences of desander and desilter is the dimension of mud cleaner cones, usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. We commonly used 8 “and 10″ cones desander to separate solid-phase particle size 47-76μm in the drilling fluids. And usually the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4″ cone to separate solid-phase particle size 15-47μm in the drilling fluid. Based on customer requirements and capacity, we can select groups of cone into Desilter.

Clients often asks us about desander and desilter selection,what model and how many cones should they use.Do they need to use shale shaker before the desander and desilter.

desander desilter shaker

desander desilter shaker

The desander and desilter selection depends on  particle size:
A,If you use 10″ desander before desilter,max particle size:47microns
B,If you do not use desander,but use shale shaker before desilter,you should use not less then 100mesh=149microns screen before desilter
C,For desander,you should use shaker,whose screen should be better not less then 40mesh=420microns
D,Suggesting Particle size rangle for 4″ desilter is from 15microns to 47 microns

Treating capacity of desander and desilter.

One ea Desilter cones 4″=15m³/h,one ea desander cones 10″=90m³/h Desander cones 11”=110m³/h.For small treating capacity,people may select single desander or desilter.For large treating capacity,it’s better to choose desander and desilter combination,also called mud cleaner,with linear motion shale shaker.

NOV Brandt Desander

Desander, as stated earlier, have no moving parts. The larger the internal diameter (ID) of the desander is, the greater the amount of fluid it is able to process and the larger the size of the solids removed. Desanders (10 in. ID) are able to remove roughly 50 percent of those solids within the 40-50 micron range at a flow rate of 500 gallons per min (gal/min), while desilters (4 in. ID) are able to remove approximately 50 percent of those solids within the 15-20 micron range at a flow rate of 60 gal/min. Microfine separators (2 in. ID) are able to remove around 50 percent of those solids within the 10-15 micron range at a flow rate of 15 gal/min. Desanders are typically positioned next-to-last in the arrangement of solids control equipment, with mud decanter centrifuges as the subsequent processing unit. They are preceded by gas busters, gumbo removal equipment (if utilized),fluids  shale shakers, mud conditioners (if utilized) and degassers.

NOV® Brandt® manufactures desander in Conroe, Texas, USA. desanders are typically configured to meet the specifications demanded by the application. Usually, the desired flow rate determines the configuration of the cones, including the size utilized. desanders are just one of the many solids control and waste management offerings that NOV Brandt supplies to the oil and gas industry. NOV Brandt’s Quality Management System is ISO 9001-2000 certified.

GN desilter is manufactured by GN Solids Control .We design and manufacture desilter for separating drilling

hydrocyclone desilter

hydrocyclone desilter

fluids,drilling mud.

1. Connect the grout outlet of sand pump and admission inlet with 6″ rubber pipe. The gas hole installed on the top of overflow pipe is used for preventing the siphon effects. A little drilling fluid will be flowed from air-bleed hole when the desilter is running. Air-bleed hole can not be blocked. If not, desilter will be failed to run.
2. Manifold of desilter: Two ends of incoming-stream manifold and overflow manifold should be connected with flange, in which the liquid can flow. The joint of overflow pipe can be rotated in any angle along the axle, through which the 8″ rubber pipe can be fixed in other drilling liquid tank easily. Incoming-stream pipe and overflow pipe of hydrocyclone should be assembled with 90° angle.
3. Firstly, open the fixed equipment of desilter screen box.
4. The operation of desilter is adjusted through the outlet pressure of sand pump.
5.Desilter Screen Assembly
The quality of installation will influence its life and running. Don’t damage the screen artificially and loosen the screen when assembling. If not, the sound “FLAPPING” will be emerged between screen and support rubber strip when shale shaker is running, in which the screen is damaged speedily. However, don’t stretch it tightly. If not, the pre-force of screen is exceed, in which the damaged degree of screen also be speeded or the screen is stretched directly.
If the support rubber strip of screen box is rugged or damaged, press and change it.
6.Slip locking equipment
This equipment locks the roll-axial to tighten the screens. Lock in roll-axial through stretching the slip by bolts. Grease should be feed into the slip locking structure for every replacing of screen to prevent the equipment sticking.
7.The maintenance of desilter screens
Iron parts and other hard particles are forbidden to destroy or tear the screen.
The meshes of screen should be matched according to performance of well liquid. The finer screen(shale shaker screen) should be prior only if the well liquid is flown from the screen, in which the effects will be better.

This Desilter should be maintained forcibly.
Adjust, clean, screw, and change part expired and damaged units if the operation exceeds 500 hours totally.
Check or change tight roll-axial of screen box, and change the cut-cone and spiral case, as well as check the insulation of motors if the operation exceeds 4000 hours totally.

GN oilfield drilling mud Desilter is discussed for application in mining slurry separtion.

Thank you for your e-mail of 12th October about your solids control equipments application.

Oilfield desilter

Oilfield desilter

We are of opinion that, during your interpretation of the technical specifications and the screen analysis of our ore, a misunderstanding must have occurred.

The result of the screen analysis of our ore we sent to you was only to give you a general information about the grain size of the ore.

These grain sizes do not reflect the particle sizes which we will feed into our process line.

The ore we are going to feed into the concentrator will preliminarily be screened through a 0,500 mm (35 mesh U.S) screen and be reduced down to -0,500 mm.

Following this, -0,500 mm material will be deslimed by separating ≥15µ using Hydrocyclone desilter and in this way we will end up with a material of -500 mm + 0,015 mm.

Studying the technical parameters of your ZQJ DESILTER, we understood that we can deslimed our (-0,500mm) material, by separating it at ≥ 15µ, using your ZQJ DESILTER.

During this operation we think that the solid rate of the pulp should be approximately 15%.

We are waiting for your answer, stating, if it would be possible to apply the process given above successfully using your DESILTER.

We can discuss and negotiate the details about your other equipment like shale shakers,decanting centrifuges, machinery and pump after having finished the negotiations about the applicability of DESILTER.
