It looks like it works really well, but, I do recommend greatly reducing flow rate to get the best separation of the finest particles. You almost want to drip the oil in, rather than stream it in. To get that g force at 8,000 RPM, the inside diameter needs to be about 4.4 inches, or, about 11 centimeters. That sounds right, if it's modeled to be similar outside diameter, to the 4.5 inch grinding wheel that is normally used.
How I would have likes to see the products (clean and residue) in the end, maybe poured into two glasses and a third one with the starting material for side-by-side comparison.
Very nice! I'm looking to make my own. Could you share what angle grinder you use (I'm not very clear if I need faster and weaker, or slower and more powerful one ... considering the added weight of the spinning bowl I assume the latter?). Also how do you attach the bowl to the grinder? Thanks!
A router could work as well. I'm not sure about the duty cycle on motors from hand tools. Angle grinders probably can't be operated continuously. Some commercial routers can be operated continually. They have induction motors with no brushes - much less heat
Nice work! I just wanted to know does all the dirt an water stay inside the aluminum billet wall? Did you thread the billet piece onto a steel spindle? Just curious how you did that.
Yes the debris stays inside the aluminium wall and the clean fluid passes ovef the top! The aluminium bowl is threaded onto the grinder shaft and it seals against the threaded boss on the bowl! It works very well!
They say alot of oil can splash 180 deg from the into so angle the intake tube at the very end to avoid the splashing . Great idea though , i was just getting ready to biuld the same thing
Back in the 60's I worked as junior engineer on a Liberty ship and we used an oil purifier for the steam turbines............basically it was a horizontal drum about 200mm diam held in 2 bearings at each end that rotated at high speed and it had a baffle plate in the end with a hole through the middle of it....... a certain amount of water was fed in one end up to a baffle plate but 10mm below the hole in the end of it.......as the drum rotated the water was thrown to the side of the drum by the centrifugal force creating an artificial horizontal gravity, and then the lube oil was flowed in forming a 10mm deep layer on top of the water .........the oil floated on top of the water....still horizontally..... and the impurities by centrifugal force went to the bottom and sank in the water............the now clean oil then over flowed the baffle plate and was pumped back to the turbine..........the water was then drained out and discarded with the impurities. I once saw and advert for a car oil purifier that worked by having a small drum rotating like a turbo from the force of the oil flow and cleaned the oil continuously while the engine was running.
there were two major makes of purifiers, sharples and delaval. sharples went out of business and parts are hard to find, delavel is still making very nice centrifuges. i used the delaval machines on several ships, wish i had one now
@@gangleweed I believe older smaller industrial engines like in buses had centrifuges to clean the oil to make the oil changes last longer but I write online some of them actually will take the good stuff out of the oil
Hi. Nice idea, making my own now from angle grinder too. But my question is, how long last the angle grinder? When I power it up, the grinder is struggling with it. just till high RPM, than is everything ok. Thank you
What is difference with all the different types of oils like engine oil compared toil gearbox oil or transmission oil differential oil do they all burn the same can it all be mild together
Hi! I love the new take on it (using a grinder and a smaller bowl instead of the big honey centrifuges. But what kind of aluminum bowl did you use. I haven't figured that part out yet. So far I've tried welding a cooking pot. Lathed braking discs. But next try was a 3d printed bowl. But I'm afraid that one will shatter.
It looks like it was milled on a lathe from a solid piece of aluminum, I have no idea what alloy though as I don't often work with aluminum I just know the different alloy classes have very different fabrication properties.
I believe he said he welded steel parts for the bowl. Likely a piece of steel plate milled or cut/ground round and a piece of schedule 40 steel pipe. Make sure it is well balanced before turning on!
What does the bowl look like? How did you make it? Im trying to wrap my head around how you would make this. Is it hollow all the way down and how far does the lip have to be. Was this machined with internal grooving bore tools?
I would like to see how the center bowl is connected as well as the outer container. I see you said that it's threaded on but how do you keep the outside bowl from spinning if it's threaded to the grinder shaft?
The inner bowl is machined from a solid billet with a blind thread taped in that grinder shaft tightens up on,the outer is sealed with an oil seal and held in place by attaching it to the original safety gaurd bracket!
Very cool. You could sell these easily. I'd probably buy one. How does the oil etc not seep through onto the grinder from the catchment, you said there was a seal, does the seal seal against the rotating shaft of the grinder?
Thumbs up from Toledo, OH. Any idea if this would separate dirt from water? In other words, can I take muddy water and feed it into the filter and trap the dirt inside the centrifuge?
Loren P. Yes you can put really muddy water in it and watch it turn clear, its a good demonstration of how well it works! Ill try and do a few more videos of it when i get time!
Thanks for the reply! I have a tumbler that I use to deburr aluminum with. Basically I am thinking about this type of filter for the media water. It becomes gray and saturated with fine aluminum particles. I would compare it to dirty river water. I'll watch for your other videos.
Great ideas here, but that flow rate is way too high for such a tiny device. You should be running about 10 gallons per hour through something like this.
What flow rate are you running it at? Looks like it's just full flow in the video. For cleaning wvo we run 20L/hr at 25c but im looking at building something that will run 100L/hr
@@marktgsxr 2 stroke engine on a chainsaw revs at about 9000 rpms full throttle. Should spin a bowl about 3x the size that you've got. Could run about 12.5 gallons a minute or close to 900+ gallons a hour. I want to build a large scale filtration system. Collect with an old 600 gallon military water trailer, gravity feed into the bowl and store it in a 5000 gallon poly tank.
Slow the flow down give it time to work. Also you need a way to separate high viscosity ( thick ) and medium viscosity separator, and a solvent leaching device, and you can save the planet!

Number of rotations per minute is crucial for oil cleaning efficiency. Angle grinder has even 12000 rpm without load but its very noisy.

Sorry no it was a one off!
Sir,is the first bowl single piece,or the top lid is brassed underneath
You can see the end of the thread from the grinder on the inside of the bowl... I'd recognize that slight dimple in the end of the thread anywhere.
You seem to be processing too much oil !?
The Aluminum bowl looks custom machined. Would you be willing to share dimensions? I have access to a cnc

what a rotating bowl
Must have aluminum?
Can't we make steel of just like pipe in less weight?
And if we are made of steel then there is a loss ?
