Desander and desilter are the second phase separation and third phase separation in oil drilling solids control system. There are different type desander and desilter for option, we may firstly to know the difference and advantages of each type, then we can know how to make choice for project.

 First type: Desander/Desilter without downstream drying shale shaker

1) Small footprint, economic choice, no consumable screens

2) For oil gas drilling un-weighted drilling mud

3) Only for wet cuttings, not recommended for weighted mud and drying solids

Second type: Desander/Desilter with Mini 2panel Shale Shaker

1) Small footprint, economic choice, acceptable drying solids

Third type: Desander/Desilter with 3panel Shale Shaker

1) Big capacity, drying solids

GN Solids Control can produce all of the solids control equipment, eg. Shale shaker, desander, desilter, mud cleaner, centrifuge, agitator, etc. GN four phase solids control mud system is working in over 60 countries and areas with good working performance and reliable lifetime.

GN Solids Control four stage mud recycling system including below parts.

Part 1: shale shaker working on mud tanks, as the first phase mud separation equipment. We have different type shale shaker for option. Including

  • a. 2 deck panel shaker which is professional for diamond drilling, or other simple construction project.
  • b. 3 deck panel shaker which can be used for workover rig and other project.
  • c. 4 deck panel shaker which is most popular for oil drilling circulation mud system and this can also used for drilling waste management.

Part 2: Desander working after shale shaker to give further treatment, as the second phase mud cleaning equipment. We also have different type desanders for option.

  • a. desander without deck shaker, cheaper price.
  • b. desander with deck shaker, reasonable price with better performance

Part 3: desilter working after desander to give further treatment, as the third phase mud cleaning equipment. We also have different type desitler for option.

  • a. desilter without deck shaker, cheaper price
  • b. desilter with deck shaker, reasonable price and better performance.
  •  Remark: we can also offer mud cleaner which is combination of desander & desilter. Smaller footprint, but better performance.

Part 4: Decanter centrifuge after desilter to give further treatment, as the fourth phase mud cleaning equipment. We have different type centrifuge for options.

  • a. GNLW223 baby mini centrifuge for diamond drilling
  • b. GNLW363 centrifuge which is most popular model for solids control / drilling waste management, GNLW363 is replacement for Derrick DE1000 centrifuge, etc.
  • c. GNLW453 and GNLW553 is GN big bowl big volume centrifuge for special requirements
  • d. GNLW452 centrifuge is middle speed centrifuge which is professional for barite recovery for oil drilling.

Any requirements, pls contact us freely

GN Solids is professional manufacturer for complete sets of drilling mud separation and recycling equipment. The conventional equipment like shale shaker, mud cleaner, desander, desilter, vacuum degasser, decanter centrifuge, mud agitator, mud gun, centrifugal pump, screw pump, etc. Here, let’s learn more about desander and desilter.

1. The general installation type and function of desander and desilter

Desander and desilter are solids control equipment with a set of hydrocyclones that separate sand and silt from the drilling mud used on drilling rigs.

They can be installed separately: Desander is installed on top of the mud tank following shale shaker and vacuum degasser, but before the desilter. Desilter is installed on top of the mud tank following Desander. They also can be installed completely: in this case, they are installed on one deck shaker and called mud cleaner or mud conditioner.

Desander removes the abrasive solids from drilling mud which cannot be removed by shale shakers. Normally the solids diameter for desander to be separated would be 45~74μm, and 15~44μm for desilter
