Think you’ve nailed this video by pointing out it’s a separater. And that there are in fact two streams

What about the geometry of the 'cone'? What effect does the angle of the wall have? Thanks. I just pulled apart my vacuum to clean it and my brain exploded with questions which led me to youtube/your video, thanks! I noticed my vacuum has a cyclone within a cyclone before a filter. I guess the outer cyclone catches the biggest particles, then the inner cyclone catches the smaller particles, then the filter takes away whatever it can of whatever is left.

Thanks, such a clear and beautiful explanation, but i still cannot quite understand why the inner vortex is formed (quasi-forced vortex), is it the difference in the pressure or the design of the bottom itself?

Would you please explain how to solve the problem of back flow of the air due to moisture in powder? The air with the powder reverses and comes out from the airlock and becomes dusty

Can a cyclone separator be used as a way to remove or prevent dust on industrial installations, like on pipes, corners and confined spaces? Great video by the way!

Please sir I need to construct a hydro cyclone suitable for separating palm kernel from the shell I need the dimension of all the parts,cylinder, cone,vovex finder,reject and accept port etc etc thank you

at 8:34, is that "gravity sifting chambers"?

Does a cyclone separator function the same if the air is forced into it (instead of vacuum force pulling the gas/air out of the top)? Dealing with a dusty material with chunky material, but the dusty material has igniting potential if ran thru a mototor impeller type (sparks from rotors) so inversing the flow of the gas is preffered.

It doesn't matter what the pressure differential is relative to atmosphere. You can either pull vacuum (below ambient) on the outlet of the separator [which is what you want here.] Or you can pressurize the input (above ambient) to the separator. As long as inlet pressure is at a predefined threshold above that of outlet pressure the separator will work. Also, consider using a brushless motor as they will not spark when setup & operating properly.

I guess the vortex area is like the eye of a tornado/cyclone, relatively low pressure so the gas naturally is drawn there?

Excellent video thanks. I have one query I'd like you to help me with please. At 6:30 into the video (Physics Note) you say... "It is a common misconception that the centrifugal force is the force that separates the particles from the gas stream BUT it is centripetal force that causes the particles to collide with the separator body." If we use the simple model of a stone being swung around in a circle on a piece of string. I thought the centrifugal force was the force exerted by the orbiting stone on the string (the outward force) and the tension in the string (the inward force), which keeps the stone orbiting in a circle, was the centripetal force. If that's right then surely: 1. The force that forces the orbiting particles in the air stream to the side of the separator cone is the outward force, that is, it is the centrifugal force..... and 2. The force that the side of the separator cone exerts on the orbiting particles (the inward force), which keeps them 'orbiting' in the spiral, is the centripetal force. So, IF the "force that separates the particles from the gas stream" (to which you refer) is the "force that forces the particles in the air stream to the side of the separator cone" (to which I refer), THEN the "force that separates the particles from the gas stream" (to which you refer) is the centrifugal force and it is not the centripetal force, which you say it is. Putting it another way surely, the "force that separates the particles from the gas stream" (to which you refer), is the outward force, which is the centrifugal force. Is it not? Please elucidate for me, Thanks Tony

The force by the string is a centripetal force, the stones mass feels a centrifugal force. The centripetal force is the force that acts to cause an object to curve toward a center, so in the case of the dust separator, it is the air causing the dust to curve. If you think it is the wall of the cone that is causing the inward force, think about a tornado; what one sees is the dirt and debris trapped inside the air vortex, sans a cone wall. The force the cone walls exert is a frictional force. The frame of reference determines on how the force is perceived, but it is the inward pull, that as you correctly state with the string analogy, that causes the air to swirl

Plz explain hydrocyclone..

when you say about density when the particle density is small, the efficiency decreases,....what does that entail? That the lower density particles are likely to escape to the upper port? I want to design something that actually encourages that in order to separate different particles.

Yes.

I'm confused by the function of (or need for) the conic section. I've seen lots of designs on youtube for DIY separators which do NOT feature a conic section at all and yet demonstrably remove well over 90% of the particles from the stream.

ironically, recent dyson vacuums are unlike this cyclone separators anymore

How do I wash river sand and remove pebbles and rocks from the sand during washing

Hello wonderful people from Savree! I bought a subscription to the site because I am interested in studying cyclones. Savree.com has the model, but there is and there is no option for me to speed up/slow down the video presentation of it (there is no video actually). Is this a bug? In the previous videos on cyclones, the narrator says that one can look at the cross-sectional area and that one can play with the video animation of the operation of the cyclone. Please help! Thank you :)

m in the centripetal force equation F = mv^2/r should have been the particle mass, not the particle size.

for anyone in the know... when these are used in a vaccuum application, what is to stop the vac from drawing air through the port where the dust is supposed to exit, bypassing the whole system? i would assume it has to be a closed system for this to work right

@RGV2300

Yes, diy dust separators are usually made with a bucket and two ports, being the top one, the vacuum inlet.

I don't understand why smaller c.s's are more efficient and remove smaller/finer dust particles. I must have missed the why there. Looking to design a small shop system with moderate airflow. It only need cover one machine or task at a time. I can not return air to the room if it contains fine dust. It's a bit of a problem exhausting conditioned air, replacing it, and placing fine dust out of the shop, too. Air-2-air heat exchange is a possibility, but that is not very effective on a small scale. Stuck....

Nice video and animation, I found it helpful. But sorry, I'm gonna nitpick a little since you've explicitly made a "Physics Note" section in your video. Your equation at 6:48 reads: F = (mv)^2/r. The 'm' should not be squared; correct equation for centripetal force on a particle in uniform circular motion is m*v^2/r. I don't know why you're calling it 'particle size', since that is ill-defined and can mean different things in different contexts. Presumably 'size' would mean a linear dimension, or some power of a linear dimension. But if that's the case, then your equation would have the wrong units for force. It should obviously be 'particle mass'. Also, it's misleading to even mention 'centrifugal force', since it's not actually a force - only the misperception of there being a force where none actually exists. Now you have confused commenters asking what is providing a 'centrifugal force' - there is nothing providing it since it doesn't exist. The only forces relevant here are (1) the centripetal force of the air stream acting on the particles entering the cyclone separator, (2) gravity, and (3) the normal and friction forces exerted by the walls if a particle's mass and geometry are such that it cannot remain entrained within the airstream. At 6:34, you state "it is the centripetal force that causes particles to collide with the separator body", which is incorrect. The particles collide with the separator body when their mass and geometry are such that the centripetal force of the airstream is insufficient to keep them entrained. If anything, it is the centripetal force that *prevents* the particles from colliding with the separator body. Apologies if I'm being too pedantic.

1. 4:18 This is where the video should start. No sense talking about variations or combinations of cyclones till the essence of a cyclone is first explained. 2. Might be helpful to explain why the inner "inverse" vortex forms and how it prevents the gas stream exiting downwards along with the dust. 3. 6:45 *r* is not the radial distance from the cyclone wall. It's the radius of curvature of a colliding particle.

Your final diagram ( at 13:13) of the multi suction inlets demonstrate an inaccurate diagram with the base of the cyclone discharging the waste into an OPEN container. WRONG!!! The suction is defeated as this would allow suction entry!!!

I love internet tutorial 99% are useless like this one. Outer vortex creates inner vortex, yeee, but WHY??? What physics law cousing it? Its like i would say: too many neutrons will cause neclear blast. GREAT EXPLANATION!!!

It's the inertia of the air at the inlet that causes the swirling. If you notice the design the inlet to the cyclone chamber is tangential to the chambers walls. The small amount of inertia of the air keeps the air moving in the direction it entered the chamber. It then "collides" with the wall and follows it. Then once the air reaches the bottom of the chamber it has to move upwards since the cavity below is of neutral pressure relative to the chamber since it should be sealed to the chamber. I state the air has to move upwards, but that doesn't mean it stops twirling. I also believe there's a point at which the twirling air naturally goes back up defined by velocity of the air (and density but assuming that's a constant normal atmosphere.) I don't think it necessarilly has to go all the way down the funnel. Would love to see a clear separator with some smoke markings to see if that's correct.

Thanks!
