These machines mechanically remove the sand/silt sized particles from the mud?

• A. Shaker
• B. Centrifuge
• C. Desander/Desilter
• D. Filter Press

Answer: (C)

Removing sand and silt from drilling mud is done with hydrocyclone-based stages called desander and desilter. The mud passes through a desander to eject larger sand-sized particles, then through a desilter to remove finer silt-sized solids. These devices rely on centrifugal forces inside the hydrocyclones to separate solids by size and density, giving cleaner mud for the next stages. Shakers handle larger cuttings but can’t reliably remove sand and silt; centrifuges and filter presses serve different roles in solids handling and mud processing.
