The investigations on the design and performance of hydrocyclones have been continued for several decades. It is well known that the structure of the hydrocyclone and the operating parameters affect the hydrocyclone separation performance. For the established solid–liquid separation system, the structure of hydrocyclone is the …

TLDR. This work proposes a new experimental method for the direct observation of particle motion in 3D printed micro-hydrocyclones and demonstrates that a well-designed device can achieve a 95% separation efficiency for a sample containing a mixture of (desired) stem cells and (undesired) microcarriers.

In this paper, the objective was set to achieve 80% solid recovery in the underflow with a 45% solid concen-tration from a feed of 20% solid concentration according to dewatering purpose. This target was set to comparable to the plant requirement. The simulation was done for a 100TPH throughput hydrocyclone.

In general, cyclones use centrifugal force to separate particles in a gas or liquid stream. In hydrocyclones, the liquid is the fluid medium. There are two design classifications for cyclones. Uniflow or swirl tube cyclones are designed so that the clean gas or liquid leaves the cyclone in the same direction that the inlet gas flows.

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation. The flow pattern in a hydrocyclone ...

Existing design equations can hardly provide reliable guidance in hydrocyclone designs and give explanations for the selected optimum range. Therefore, a new method combined flow patterns and equation models (FP-EM) for hydrocyclone designs is proposed in this paper. The feed flow rate is used as a parameter to evaluate the FP-EM method.

Hydrocyclone is a simple mechanical device, with no moving parts, where solid particles are separated from liquid with very little head loss. As its name describes, it uses a cyclone or tangential injection flow process enhancing the centrifugal forces and moving solids outwards. The dispersed particles, move downwards in a spiral path into an underflow …
