The application of KOSUN desilter

KOSUN desilter is the third solids control equipment which processes particles above 15-44μm in the drilling fluid, facilitating better treatment effect of the next stage equipment and decreasing its workload.

The structure of KOSUN desilter

KOSUN desilter is a combination of cyclone desilter and shale shaker of drilling fluids. 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.

KOSUN Desilter

While installing a desilter, please follow these general recommendations:

1. Size the desilter to process 100-125% of the total mud circulation rate.

2. Take the desilter suction from the compartment receiving fluid processed by the desander.

3. Keep all lines as short & straight as possible.

4. Do not use the same centrifugal pump to feed both the desander & desilter. If both pieces of equipment are to be operated at the same time, they should be installed in series and each should have its own pump.

5. Direct the overflow line downward into the next downstream compartment at an angle of approximately 45%.

6. Keep the end of the discharge line above the surface of the mud to avoid creating a vacuum in the line.

7. Install a low equalizer line to permit backflow in to the desander section.

8. Install a guard screen over the suction with ½’’ slots to prevent large trash from entering the unit and plugging the cones.
