How do you size a hydrocyclone separator?
Sizing your hydrocyclone separator The volumetric flow rate that must be processed, solids feed rate, solids feed concentration, the feed size distribution of the solids feed, the required duty of the hydrocyclone and expected cut point are some of the factors that must be considered.
How do you calculate pressure drop in hydrocyclone?
The solution of the equation 3 is: P = D* Vt * ln (r) + C (4) This solution gives the pressure distribution in the cyclone flow field. The cyclone pressure drop is a function of the cyclone dimensions and its operating conditions.
What is hydrocyclone pressure drop?
The pressure drop is the total pressure difference that is the difference between the inlet pressure and outlet pressure. Pressure drop inside the hydrocyclones are investigated, and the results are shown in Fig.
What is cut size of a hydrocyclone?
The cut-size, indicated as 50, is defined as the size of the particle in the Particle Size Distribution (PSD) that has a 50% probability of reporting to either the underflow or the overflow of the hydrocyclone (Bradley, 1965).
How do you size a cyclone?
Sizing a cyclone involves many factors, but the most important dimensions to consider are those of the inlet and the main body chamber. The sizing of inlets affects the airflow capacity of a cyclone, and also influences its pressure drop at a given flow velocity.
What’s the difference between cyclone and hydrocyclone?
A hydrocyclone comprises a cylindrical shaped feed part with tangential feed; an overflow part with vortex finder; a conical part with an apex. A cyclone has no moving parts.
What is the purpose of hydrocyclone?
A hydrocyclone is a high-throughput gravity separation device used for separating slurry particles based on particle weight. For example, particles of similar size but different specific gravity, or particles of different size but identical specific gravity.
How efficient is a hydrocyclone?
The sharpness of the newly designed hydrocyclone increased from 80.5% to 93.3%. The vortex finder separated approximately 89.9% of the fine particles in impurities, while 51.0% of TiO2 was recycled by the spigot.
Why is a hydrocyclone important?
Hydrocyclones (also referred to as cyclones) are an efficient way to separate slurries. With no moving parts, they depend on the feed pressure, or velocity, into the cyclone to generate a centripetal force. This centripetal force allows the cyclone to separate coarse or dense particles from fine particles.
How do you determine the size of a cyclone separator?
How do you calculate hydrocyclones?
Generally, hydrocyclones are usually calculated by successive approximations, by setting hydrocyclone dimensions based on available experimental data; after that, basic parameters (flows and degree of separation) are calculated. In case of a mismatch, input parameters are changed, with a subsequent iteration to follow.
What is the density of water needed to suspend a hydrocyclone?
The suspension can be directed to the hydrocyclone at a pressure p = 0.7 MPa. The density of water to be assumed equal to ρ ж = 1000 kg/m³. Problem: Determine which of two hydrocyclones is suitable for fulfilling the task.
What is the difference between D1 and D2 in hydrocyclones?
Statement of problem: There are two hydrocyclones with the same upper and lower pipe diameters, d в = 140 mm and d н = 80 mm, respectively, but with different diameters of the cylindrical part of the body, d 1 = 400 mm and d 2 = 500 mm, respectively.
