Desander and desilter (or mud cleaner) usually used in manage water-based drilling mud.

Now let’s talk about the differ of desander cone and desilter cone.

Cone size, is the biggest difference between de-sander and de-silter. Desander cones are usually available  8 – 12 inche (normal 10 inch) to remove drilling solid particles upto 60 microns with 4 inch inlet and 6 inch outlet; desilter cones are 4-6 inche ( normal 4 inch) to remove solids particle (fine sands and silt) down to 20 micron with 2 inch inlet and 2 inch outlet.
