Desander

The desander with underflow shaker is also called Mini desander cleaner which is applicable for both weighted and unweighted drilling mud, while traditional desander no underflow vibrating screen only for unweighted drilling fluids. And comparing with large size mud cleaner, the Mini Desander is cost-effective. For compact mud system used in HDD, CBM, water well drilling and Mining project, Mini desander is an Ideal choice.

Mud Desander for Drilling Mud Separation System:

Desander is placed after shakers and degasser but before desilter. Different from the Shale Shaker separating solids by screen, desander removes those abrasive solids from the drilling mud by centrifugal force. Due to different density of solid and liquid, the very fine solid which cannot be removed by shakers could be separated out by desander. Desander is also the first one equipment to separate by using centrifugal force.
