Highlights Spatial tracks of a particle were obtained as it moves through a hydrocyclone. The particle was located with a standard deviation of about 0.2 mm once per ms. The particle underwent recirculatory loops in the radial-axial plane. The particle exhibited a complex flow at a specific position low in the cyclone. The flow-instability …

The MEP Hydrocyclone uses centrifugal force to separate solids from liquid or to classify coarser or greater mass solids from finer or ... at the inlet volute into a spiraling passage through the Cyclone. ... once the conical section is reached, downwards toward the apex discharge. Applications. The Hydrocyclone is used for: Dewatering ...

Once the steady state condition was reached, the spray discharge through underflow was photographed using a digital camera (Sony-DSC HX-300, 50 × zoom, 20.4 MP) positioned on top of a tripod (Benro T660EX, Max Height 1450 mm) at a distance of 4 m from the test rig. The shutter speed of the camera was fixed at one frame per second …

In this work, the hydrocyclone geometries namely, overflow diameter, underflow diameter and inlet dimensions are altered for analyzing the performance. The Reynolds Stress Model (RSM) is applied to forecast flow arenas and its radial profiles. The Discrete Phase Model (DPM) is applied to examine the separation effectiveness of particles from water. Three …

The water reuse system consists of a settling maze and a vertical pump to pump the water back to the coke cutting water tank after separating the coke fines by passing it through hydrocyclone. The settling maze consists of 4 partitioned chambers, with water cascading from one chamber to the other, thereby effecting coke fines settling at stages.

Simulations were performed for various hydrocyclone staging arrangements using experimental results from single‐stage wide‐angle hydrocyclone separations when processing fine ... The staging arrangements included re‐treating the overflow and/or underflow streams in both once‐through and recirculating circuits. The …

the vortex finder, discharging through the overflow pipe. This product, which contains the finer particles and the majority of the water, is termed the overflow and should be discharged at or near atmospheric pressure. The higher mass particles remain in a downward spiral path along the walls of the conical section and gradually exit through

The hydrocyclone is a static, continuous particle size separation device that can also be used for phase separations, including solid–liquid, liquid–liquid and liquid–gas …

Since the flow enters at the periphery and top of the hydrocyclone and leaves through the top and the bottom of the vessel at its center, there is a three-dimensional fluid motion, called vortex motion, with tangential, axial and radial velocities.The vortex motion produces a low-pressure zone in the center of the device …

The VorSpin Hydrocyclone Series: Hydrocyclone applications have a wide appeal to engineers and project managers in many industries because of their designed simplicity with no moving parts.The Fields of Industry applications are shown below: Food and Beverage; Chemical; Pharma; Refineries; Petrochemical; Breweries; Distilleries; Some …

Once the hydrocyclone is operational, any significant changes in operating conditions can be accommodated via vortex finder and spigot diameter changes. Seldom will a different cyclone diameter be required. ... This simple process separates slurry mixtures so that larger particles leave through the hydrocyclone's underflow. The remaining ...
