The polyurethane hydrocyclone is a simple and easy to maintain mechanical separation device. It’s crucial part of desander, desilter and mud cleaner. The split type is obtained by converting the feed energy of the power input into the centrifugal force inside the cone.
A mud cleaner is a combination of desanders and/or desilters to remove drilled solids from mud. -wiki
Mud cleaners can be leased, rented, purchased as independent units, or assembled on location. When mud cleaners were invented in 1971, main shale shakers on drilling rigs were either unbalanced elliptical or circular motion machines.
Other than the drill floor itself, the solids control system requires more attention than any other single rig system whether onshore or offshore. For that reason, it is most important that the solids control system is designed to be as efficient and as maintenance free as possible. This section will discuss that pan of the mud system extending from the bell nipple (or diverter housing outlet) to the mud pump suction piping.
