Before GN provide 3 size desander cyclones, 8 inch, 10 inch and 12 inch. The 8inch cyclone is cast iron with Polyurethane material. The 10 inch and 12 inch desander cone is 100% PU material. Now our standard cone size is 10 inch with PU material, and the installation dimension is replaceable with Derrick 10 inch cone. The cut point separation is 45~75 microns, which is usually used after shale shaker and before desilter cone. 
We have 3 options for the desander cyclones, 1ea cone can treat 500gpm, 2ea cone can treat 1000gpm, 3ea cone can treat 1500gpm. You can put the desander cyclones on desander equipment( without underflow shaker), or on GNZS752 shale shaker( mini shaker) or GNZS703 shaker to be act as mud cleaner.
