Breakdown cause of desilter with shale shaker screen

Now, with the stringent environmental regulations and high mud costs, the economics of an effective mud system come into consideration. Different solids control companies introduce zero-discharge systems, closed-loop systems,"quick move" technology, screening technology, disposal options etc.

desilter with shaker screen

Desilter is a combination of desilter hydrocyclone and shale shaker screen. The polyurethane is used for hydrocyclone. The lower little shale shaker is elliptical. The vibration generator is driven by vibration motor, which makes the screen box keep a integral forward elliptical motion.

Breakdown cause of desilter:
(1) Too small of underflow opening.
(2) Plugged at feed inlet or outlet.
(3) Backflow from overflow manifold, or centrifugal pump impeller worn out or too small,
(4) Drilling through hydratable clays will cause increased viscosity.
(5) Strong vacuum in manifold discharge line.
(6) The apex cone nut is tightened too much which does not allow fluid or solids to exit the hydrocyclones.
