Performance improvement of a cyclone separator using
The cyclone with DVF 1 had the minimum separation efficiency even lower than the base cyclone because the tangential velocity was decreased as the fluid flowed more smoothly through this cyclone. It was proved that the proposed cyclone with CVF 1 was capable to collect finer particles ( d p = 2 µm) at high inlet temperature ( T = 700 K).
Hydrocyclone Working Principle
The purpose of the Vortex finder is to separate the fine material from the coarse as it spirals around the vortex. The WIDTH of the Vortex finder will determine how far into the coarser material the …

Which Dust Deputy Cyclone Separator Should I Buy? | Oneida Air …
Ja - The original Dust Deputy has a 2" port and is best for vac's that have 2" or smaller ports. The 2.5 Dust Deputy allows up to 2x the airflow for vac's that have 2.25" or larger ports. The Dust Deputy Low Pro also has the improved airflow of the 2.5. It is best for people who need their separator to be as short as possible.
The Sizing & Selection of Hydrocyclones
the cyclone axis. The basic area of the inlet nozzle approximates 0.05 times the cyclone diameter squared. The next important parameter is the vortex finder. The primary function of the vortex finder is to control both the separation and the flow leaving the cyclone. Also, the vortex finder is sufficiently extended below

For both of them, there does exist an optimum air-liquid ratio for hydrocyclone separation. For the air-injection hydrocyclones, (i) the vortex finder diameter of the air-injection hydrocyclone should be larger than the hydrocyclone without air injection. (ii) The micro-pore diameter is proportional to the separation efficiency.
Title: A CYCLONE FOR A REASON Dense Medium Cyclone …
The advent of the large diameter, high capacity, very efficient dense medium cyclone was at hand. Essential ancilliaries. Together with dense medium separation comes a host of support equipment without which the DM cyclone or even the drum, cannot function. These relate to primary classification and desliming, washing and recovery of
Cyclone separator
Cyclone separators is one of many air pollution control devices known as precleaners since they generally remove larger pieces of particulate matter. This prevents finer filtration methods from having to deal with large, more …
Gravity gold recovery
Gold is one of the few metals that occurs in metallic from in natural geology and it makes sense to recover it prior to any chemical processing. Given its very high SG of 19.3 comparative to host rocks in the 2.8-4.0 range, gold is very amenable to separation using gravity techniques.
Facts at your Fingertips: Cyclone Separators
Typical cyclone separators have efficiencies of 70–90%. Gas inlet velocities should be in the range of 100 to 150 ft/s, but may be limited by re-entrainment of dust particles or by unacceptable pressure drop.
Double-Eccentric Design for the Vortex Finder of a Cyclone Separator
In the present study, a double-eccentric design for the vortex finder of a cyclone separator was proposed to enhance the cyclone performance. Using the numerical approaches, the flow field inside the cyclone was simulated and the cyclone performance was evaluated. The orthogonal method was adopted to obtain the optimal …

Material classification for fine powders | Processing Magazine
Cyclonic separation is a method of removing particulates from an air, gas or liquid stream using a vortex instead of filters. Facilities can reuse the fines or the coarse material separated by the cyclonic separator. Traditionally, a cyclone is not seen as the most effective type of air classification, but it can serve a purpose.
