The Working Principle of the Hydrocyclones

For the work principle of hydro cyclones, it works like this. First the drilling fluids are sucked up to 0.25Mpa ~ 0.4Mpa by sand pump, and enter into the cones through the side inlet which is normally only 2-1/2″ diameter. The fluids then flow spirally inside of the cone. Affected by the centrifugal force, the heavy solids in the fluids would be thrower towards the inner wall of the cones, go down to the bottom, and discharge through the sand discharge port, while the light fluids would go up and discharge through the upper outlet. The diameter of the bottom discharge port is adjustable, and with a cover of hydro cyclone.

As a quick-wear part of desander&desilter, the lifetime of hydro cyclones is not so long as other parts. So it is necessary to check their working condition, and replace them with new ones. As a whole set of the hydro cyclone, clamps & flang are also replaced together with the hydro cyclones.

Desander & desilter are consisting of hydro cyclones, high pressure flow pipes & a small shale shaer at the bottom. For desander & desilter, only one vibration motor is used to drive the screen basket. While for high efficient it would need two motors. There would equip two 10″ or 12″ diameter iron hydro cyclones for desander just as the solids need to be separated is relatively big, and include some sands in the mud. While for desilter mini crusher for sale, it would equip 6 to 12 pcs 4″ diameter hydro cyclones which are made of wear resist plastic.
