Bentonite Mud Recycling Equipment is also called drilling mud solids control equipment,usually,use linear shale shaker,mud cleaners,and decanting centrifuges to recycle bentonite mud.
GN Solids Control Supply a complete list of Bentonite mud recycling equipments.
Bentonite is an absorbent aluminium phyllosilicate, generally impure clay consisting mostly of montmorillonite. There are a few types of bentonites and their names depend on the dominant elements, such as K, Na, Ca, and Al. As noted in several places in the geologic literature, there are some nomenclatorial problems with the classification of bentonite clays. Bentonite usually forms from weathering of volcanic ash, most often in the presence of water.
Sodium bentonite expands when wet, possibly absorbing several times its dry mass in water. Because of its excellent colloidal properties (see Odom ref below) it is often used in drilling mud for oil and gas wells and for geotechnical and environmental investigations.
Much of bentonite’s usefulness in the drilling and geotechnical engineering industry comes from its unique rheological properties. Relatively small quantities of bentonite suspended in water form a viscous, shear thinning material. Most often, bentonite suspensions are also thixotropic, although rare cases of rheopectic behavior have also been reported. At high enough concentrations (~60 grams of bentonite per litre of suspension), bentonite suspensions begin to take on the characteristics of a gel (a fluid with a minimum yield strength required to make it move). For these reasons it is a common component of drilling mud desander used to curtail drilling fluid invasion by its propensity for aiding in the formation of mud cake.
In industrial drilling field,bentonie mud recycling equipment are widely used.
