In this video we show how centrifuges work with some colored water spinning at various speeds and then show the operating components of an Extreme Raw Power Centrifuge that can be used for filtering vegetable oil. This one is unique because it comes with an AC Drive that allows you to control the motor from 150 to 6,000 RPM's.
Be sure to check out the first video we did as well.

Centripetal Acceleration is equal to v^2 / r.
One earth "gravity" acceleration is 9.8 m/s^2. You must take the radius and rotational speed of the motor (in RPM) to find the velocity tangent to the radius.
Say a centrifuge is 50 cm in diameter, has a radius of 25 cm, or .25 m. It is spinning at 3000 RPM.
The circumference is 2Pi x r. The circumference is 1.57m. V = 1.57m x 3000 RPM = 4710 m/min, or 78.5 m/s.
(78.5m/s)^2 / (.25m) = 24649 m/s^2. Divide by 9.8m/s^2 gives you 2515.2 earth G
Centripetal Acceleration is equal to the square of an object's tangential (not angular) velocity, divided by the radius of rotation.
The equation looks like this: A = (v^2)/r
To convert your answer into Gs, simply divide the answer by 9.8.
For example, if this is spinning at 750 rpm (roughly 80 radians/second), and the water is 10cm (0.1m) from the axis, the tangential velocity is (radius x rotational velocity) = 80rad/s x 0.1m = 8m/s.
So the acceleration is (8^2)/0.1 = 640m/s^2 = 64G
Why does the liquid go up and out of the centre if the centrifugal force is outwards and the volume of liquid is does not reach the inner lip? Does the liquid compress so much?
It can filter oil effectively clear down to 1 micron. The flow rate is what determines how small it'll filter down to. The slower the flow, the finer the filtration.
It is really simple. to calculate the g-force inside a rotating cylinder use the following formula: .0000142 * Bowl diameter * speed squared. so: if the machine shown has a 12" diameter bowl, and is spining at 6,000 RPM the g-force generated is: 6,134.4 Gs.
@freeekonaleesh2 This one is designed only to remove solids. There are centrifuges on the market that'll separate two different liquids, but they're a completely different design. Because the dye is a liquid, this one won't separate it from the water. The green dye is just to illustrate how it works.
That would be awesome! It'd help it out quite a bit!
@UtahBiodiesel Assuming the radius to the outer wall is around 100 mm it would generate an accelleration of around 4000G @ 6000 RPM on the outer wall.
Do you guys play with the decanter centrifuge? I have quite a few I'm motivated to sell!
@TheVirtouso
Nope.
What micron level dose it filter too and dose it actually separate the water out?
Has there been any test done to prove that ts works?
Also, I was going to do the WVO conversion but i figured why take the chance at destroying the engine when I'm getting 40-46MPG average depending on the driving conditions. Alot better than 17-19MPG in my ruck. My 2004 Golf TDI is perfect.
Hi there.
Is this the type of centrifuge I need to dewater and to remove contaminants from waste motor oil before burning?
Can you tell which model is the best one to purchase from yourselves?
Thanks.
Is it possible for the reverse to happen?? Meaning, instead of the water being pulled to the edge, can you the water be focused to a single point.. a central point?
@saintveil
For that you'll need.. well a still. It may work as an oily water separator but even that will be llimited since it seems to have a small capacity for water and that's what you'll have the most of.
For doign what you are lookign to do you may want to examine vacuum distillation. Those work on high vacuum and boil water at just over room temprature.
what diameter is the bowl, and what material is it made from?
does it show what hp the motor is?
why did you decide to use a ac motor with vfd vs dc motor and pwm controller?
Nice work. Thanks for the video. What are you using to slow the motor down? I need to be able to slow/adjust the speed of some 1 phase and some 3 phase motors for (hobby) projects, so it needs to be cheap. Any good ideas?
It's an AC Motor drive. It was a Direct Logic controller from Automation Direct. You need to have a 3-phase motor to pull it off too. The drive varies the voltage and frequency to change the speed of the motor.
How mas pris youe.
Variable speed router.
Nice ILike it thanks buddy
bravo!! ❤️❤️
How did the disk get out of round tolerance ?? Peace
What micron level dose it filter to?
8" diameter bowl x 2" deep. Made from cast aluminum. Motor is 1/3 HP
@Pimpimma
Yep. It really is 6,000 RPM.
so what if I use a simple water settler b4 the oil enters the centrifuge???
Very helpful for an exam I have coming up. Thanks!
g= (2 * 3.14 * f)^2 * r
r= half of diameter of the bowl
f = frequency of rotation (rotations pher second)
6000 rpm = 6000 rotations pher minute = 100 rotation pher second which means f=100.
does anyone know of an equation that can tell me how many g's is being generate once a centrigufe starts to spin???
what's the whole mathematic's behind it.
@TheVirtouso Utah Biodiesel Supply and WVO Designs both sell these. Visit utahbio dot com on the web.
good video
Thanks!
can any one really tell how much clean fuel you get from 1 gallon of wvo ( like fries oil ) thanks
esto filtfa el aceite?
@GUYANESEGT: g=r*w^2/9.8 where r = radius of bowl in meters, w = 2*pi*(revolutions per second)
Anyone knows the specification of dynamo which this kind of Centrifuge machine use?
I suspect the controller is a VFD (variable frequency drive), running an AC motor.
yes it's simply the centripetal force divided by g=9.8m/s²
F = ma = m4π²r/T²
a = 4π²r/T²
a/g = 4π²r/(gT²)
and there you have it.
a/g: g-force factor
r: centrifugal radius
T: time per revolution
in this example i estimate the radius to be about 15cm = 0.15m. 6000rpm = 100rps
a/g = 4π²r/(gT²)
a/g = 4π²*0.15m/(g*(1/100 1/s)²)
a = 6000g
so it's about 6000 G's
That honestly depends on what they give you.
Holy crap that thing is loud!
What type of motor are you using? Is that direct drive?
its an ac motor with vfd controller. Cnc controllers use them.
Direct drive with a VFD Controller
you can only separate the green from the water if it would be a suspension (like blood for example). if it's solved in the water you can't separate it that easily. the electromagnetic force holding the solution together is way too strong for a centrifuge.
i don't know if this water and dye is a solution so i can't get you a clear answer
You'll want to contact the manufacturer directly which is WVO Designs. Hit my centrifuge page on my site (link in description) and you'll see the link to the manufacturer.
I was reading Fahrenheit 451 they mention this word. This part where the guy is talking about another revolution to change society, but the old character mentions this world.
how much it cost if i buy one to recycle 100 litere a day ?
and where can i buy it?
As of 8/7/14 the basic model runs $1197, the extreme runs $1497. They're available at Utah Biodiesel Supply (Google search as I can't put a URL in a comment).
And this is superior to traditional filtering?
Nice centrifuge. But...
Never before I have seen such a frequent violation of simple precautions for assured physical integrity, especially in an educational documentation. You simply do not poke the massive rotor at over 1500 rpm with your finger... at least if you want to keep them.
@GUYANESEGT I'd imagine if you give WVO Designs a call they could tell you.
Where can I buy one for cheap?
It is a perfect product. I mean it was a perfect product until I saw the price tag ;D
I would so help promote your product if you donated one for my one step process portable factory
Yep. Definitely not cheap.
Also if this really worked the color die in the water would separate from the water.
the design almost looks like a small brake drum spinning inside a larger brake drum... ;)
water doesn't compress......
Agreed, I think what they mean is, it changes from a 'triangle' profile (across bottom & side), to a thin layer (only on the side). As this happens, the width of the lower edge becomes less (-i.e. is 'compressed').
And we definitely can not see how compressed the water is. :)
Its not RPM, its Hz.....
$1630. WHY so much?? Even a top-tier iPhone is only $1599.
i want to recycle waste engine oil
Sweet! These work great with waste motor oil.
opened centrifuges are extremely dangerous, if rotor were damage could hurt you, are not children's games.
if thats 6k rpm, thats just toally unsafe. You'd never, in a million years get that CE marked...
Please call it a "cent-RI-fuge" and not a "cent-ER-fuge". You are mispronouncing that word.
eBay guyszzz! Yeah not this one
Centrifuges DO NOT FILTER. They SEPERATE. If they filtered you would be able to quote a micron rating for this machine which you can't can you? You and everyone else who makes these honey spinners is so confused its embarrassing. As the bowl fills with heavy particles the separation quality reduces until it' full at which point there is ZERO separation.
This one will remove contaminants extremely well, but I wouldn't rely on it solely for a dewatering device. While bowl style centrifuges definitely can help remove water, the heat, circulate, and spray method is much better (see our website - Utah Biodiesel Supply - for plans on building a dewatering tank). Either the 3450 or the 6,000 RPM model will work well.
Depends on what you mean, but in most cases, yes. This is because it allows you to filter in a somewhat automated fashion, the microns you can get down to is extremely small (down to 1 micron), and the bowl is reusable vs throw away filters.
True. One of these days I'll have to run some nasty oil through it. It's amazing at how well it'll clean the stuff up.
It just sprays on your hand. The bowl itself is aluminum so even if you touch it at 6,000 RPM it won't burn. Not that I recommend touching it at that speed, but that's all that'll happen.
I don't think so. A good analogy is to hook a ball to a string and twirl it above your head. The force you feel on the string is similar to the force being exerted on the water. centrifugal force if you will. So the water basically will get flung up against the wall.
