We walk you through the direct drive style oil centrifuge, and explain how rpm and flow rate affect your oil cleaning. pabiodieselsupply.com/ www.centrifugefordummies.com/
the slower RPM and Flow Rate offering higher filtration is a curious artifact at first, until you consider surface tension permeability, and introduce the fact that surface tension is reduced with higher temperatures, it all starts to make sense. Have you considered experimenting with grounding the centrifuge to reduce naturally occurring electrical fields that may disturb the surface tension inside the centrifuge? Perhaps experiment with placement of external magnets to contour and counter the naturally occurring electrical magnetic field generated by the rotation of the centrifuge. Also... the sludge generated can be filtered with propane, to extract a) more propane, b) naphthalene C) asphalt tars. Currently these systems can be found in large recycling centers, but developing a small system to sell to those who want to recycle 'everything' and have no hazardous waste generation would be cool. Just not really sure what people would do with spoonfuls of asphalt at a time...;) The extra propane and naphthalene however can be readily used. As it stands, storing the sludge in a 5 gallon plastic bucket with a secure lid and taking to a local hazardous waste facility is the proper way of disposing of it, as far as I know. PS.. sorry for the lengthy blog
He's only bring up rpm because his competitors that sell these sell higher rpm units and they make it seem like that is the main factor for cleaning. It's not it's rpm and bowl diameter which equals g forces applied to whatever is in the bowl. High g forces and slow flow rate( longer time under high g forces) equals the machines cleaning ability. There's other factors as well temperature to reduce viscosity which allows particles to move to the outside of the bowl easier as well as evaporator the water. There's other factors too I don't know much about like how often the bowl is emptied while cleaning, plates inside the bowl, small layer of water inside the bowl..
enjoyed the video. for a WMO recycling project I want to install a brass bulkhead into a barrel so I can control the draining from the bottom to the centrifuge. I figure the brass will hold up better than plastic. it comes with a washer but will it seal better if I use something like JB Weld on it? or is it unnecessary? I'm concerned about the effect of petroleum on the bulkhead and seal. thank you for any assistance you can provide.
I'm just a nube at this. This is a far cry above what I've been doing I simply stretch a couple layers of cloth over a bucket and pure oil thru it. Then run the tractor on it. Can you tell me how to regulate the flow of 5,10, 20 gallon an hour? I mean is there a flow meter or are you simply timing how long it takes for a gallon to finish?
Increasing RPM from 3,450 to 6,000 produces 3.03 times greater g-force. For a given bowl design, it takes 1/3 as long to achieve full stratification, and settle out particles. (assuming precipitation rate is proportionate to centrifugal force) It may well be worth the up-grade, if available.
Howdy, we are working on a 6,000 rpm motor and will have a protype working in the next month or so. At 3,450 rpm we currnetly have a G-force of 1,605. The 6,000 rom motor will give us a g-force of 4,856 respectively. This is close to triple the g-force as you say. Regards, PA Biodiesel Supply
If slower is better, why not run the batch once at 3.3 gph? Running 100 gal twice once at 10 gph and once at 5 gph takes 30 hrs Running 100 gal once at 3.3 gph takes 30 hrs You are always saying slower cleans better so why not just slow down?
so if i run 1 gallon an hour on waste motor oil on the centrifuge will it clean it best to run it 4 times through the centrifuge at 1 gallon an hour im wanting to buy one to make my own deisel but not sure the best way to do it. and should i use a large centrifuge first then a small oil filter sized one for polishing the oil be for making deisel with it
Howdy! We typically recommend 5 gallons per an hour flow rate. You may find it more effective to pass the oil at 5gph then cycle it through a second time instead of 1 gph and 1 pass. Regards, PA Biodiesel Supply
I don't disagree with you about lower RPM = cleaner oil, but I do not understand why that is the case. I would think that, at a higher RPM, the centrifugal effect on the containments would be greater, thus pulling them to the perimeter of the bowl more easily. Also smaller particles would have a greater chance of being pulled to the outside. Why is this not so?
He didn't say lower rpm equals cleaner.. it's all about the g forces which is rpm and diameter of the bowl. He's saying slower flow rate is cleaner. He just talking about the rpm because it's not the main function of cleaning power it's have the equation bowl diameter is the other half.. other companies that sell these advertising rpm when it 2 factors that really determine cleaning power
Nice video, Dude.👍🏻 I like all that "um"-s and "ok"-s 🙂
Out of all the competitors out there, you got the best videos! You just might have me sold!

How do I purchase this UF centrifuge?
If slower is better, why not run the batch once at 3.3 gph?
Running 100 gal twice once at 10 gph and once at 5 gph takes 30 hrs
Running 100 gal once at 3.3 gph takes 30 hrs
You are always saying slower cleans better so why not just slow down?
what is the latest price of this machine
I think I understand, your telling me that every once in a while I need to stop the centrifuge to allow it to drain then start it back up again?
so if i run 1 gallon an hour on waste motor oil on the centrifuge will it clean it best to run it 4 times through the centrifuge at 1 gallon an hour im wanting to buy one to make my own deisel but not sure the best way to do it. and should i use a large centrifuge first then a small oil filter sized one for polishing the oil be for making deisel with it
Howdy! We typically recommend 5 gallons per an hour flow rate. You may find it more effective to pass the oil at 5gph then cycle it through a second time instead of 1 gph and 1 pass. Regards, PA Biodiesel Supply
Question: at what temperature are you heating the oil?
We recommend 170* to 200* F. Regards, PA Biodiesel Supply
Can we use this machine to separate the Chlorella algae cells from its water?
Howdy! This centrifuge can remove algae from water. Regards, PA Biodiesel Supply
I'm interested in buying a centrifuge. I can send my details privately.
Can use for v8rgin cocunut oil
Depending on the amount of containments and viscosity of the oil, yes you can.

PA Biodiesel Supply
Ok

Why is this not so?
Spin it too hard, and the heavy chunks we want to fall out, get shoved up the wall.

Kubota on Yours feets?
OK! now buy some mens shoes.
OK...
