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 america  company ‘s desander  is  used  in  drilling fluid in the borehole after sand pump to the lower screen the first level filter to remove the large size solid particles, then into the sedimentation tank below. By the second sand pump from the tank to above desilter of the second filter, after desander  below the upper deck of the vibrating screen mesh third grade filter. After after three-stage filtration purification of liquid is clean, can through the sand pump or overflow to other sedimentation pool or storage container in order to continue to use. In addition to the mud cleaning equipment, a group of mud mixed cell installed in the side of the tank. It is in the process of purification, add the necessary drilling mud materials control mud weight.

such  as  the  trenchless technologies as well as HARD DISK DRIVE task tend to be extremely used within the city drinking water tube, sewer & air pollution manage, energy & telecommunications, essential oil & gasoline area and so on. Trenchless task as well as HARD DISK DRIVE program create some waste materials. Pre-estimates associated with quantities as well as solids manage gear will help drilling rig to lessen the actual coastline as well as reduce the actual air pollution. GN Solids Manage thoroughly specializes in the actual higher solids tools  as  the  mud  desander  is  very  import . in order to bring about the actual trenchless. Since the worldwide manufacturer, GN Solids Manage along with API & ISO accreditation produce best regular solids manage tools for example shale shaker, dirt solution, decanter centrifuge, vacuum cleaner degasser, dirt gasoline separator, up and down reducing clothes dryer, centrifugal pump motor, shear pump motor, agitator as well as auger to satisfy customers expection.

The  desander   is  used  for  the trenchless system, also called horizontal directional crossing the mud system, crown to solid control is a company specializing in the production of horizontal directional crossing the mud system manufacturers, our company engineer with more than ten years of horizontal directional crossing the mud system design and production experience, our company has a mature production process and quality control system. Recently my company to Indonesia, Singapore, Libya and other countries export several sets of trenchless horizontal directional crossing system, customers are very satisfied with the feedback. My company can according to the different requirements of customers to configure different solutions, to provide customers the best in the most economic way, crown to solid control has a reliable customer service, our company engineer will provide the satisfaction for the customer the post-sale service, and can provide comprehensive training for our customers.

The site can give you more options for choosing equipment.

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
