Hydrocyclones are major components in desander, desilter and mud cleaner and assist most of their works. A hydrocyclone has a upper casing, a lower casing, a underflow mouth as well as auxiliary parts. The upper casing is an inlet chamber in cylindric with an inlet pipe on one side and a vortex tube in top middle as the overflow. The lower casing is a cone whose angle ranges from 15~20 at the tip. The underflow mouth is located at the bottom as the discharge port for solids. The work principle of hydrocyclones is to separate two or several components with different densities with the aid of centrifugal force. After the mixture is sent into hydrocyclones by certain pressure, it gradually flow into a high-speed rotation where the heavy phase form an outer swirl by moving downwards along the
