What is the powdery material you wish to leave behind? How big are the magnetic particles? Can you use a two part suction process where the first filter holds back the larger particles and the next the finer (dust).

First thing to come to mind is a "Trumble"( I think that is the right name, a rotating drum) with a small mesh screen and a HI flow vaccum/blower to remove the dust or a water high pressure spray wash.

Electro static seperation might work.

Please try to explain how your method works. You are explaining this concept to many people.

Electrostatics works by giving the powder a charge and the collector plate an opposite charge this makes the two highly attractive and the dust, powder will be separated from the relatively conductive magnetic particles these can be held back by a magnetic collector plate, use a fan to blow the powder from the mix. (See Wikipedia) for details on electrostatics. Air purifiers for domestic use use 3Kv Dc to pricipitate dirt from the air. Negative ion stream.

If the power is smaller than the magnatic particals, try a sifting screen. The dust will fall through, and the other sutff will remain on top. Each could be dumped into a different channel at the end of the sifter.

If they are the same size, you might want to try magnetising the sifting screen. The motion will shake the power off of the other material.

I'm ignorant in this area, but neutralize or counteract the "non-magnetic particals" by using ionized air. If your dealing with a positive charge then you would use negative ions to counteract the particals. Maybe by using your electromagnets to hold the magnetic material you can use a stream of ionized air to blow away the unwanted particals. I'm not sure, but it's a thought.

You totaly mix up what I am saying go backl and read it again s l o w l y.

My friend; As I know what details you have or the details of the project you are making an endevour; I will say this for your potential thought toward the subject. Please be advised that I am assuming that you are an smart fellow but perhaps some things at some times escape you as they do with all others. I do not contest to give you a solution but I shall give it my best effort. Please don't take some of my presumptions as critique. Thanx. It is my belief that it is a filter you are after? That is to say you want to eliminate the non-magnetic particals from the magnetic ones. ( If I am incorrect, this answer should cover a situation where-by it could be a closed loop filter for continuous operation). Off we go...Any magnetic material may tend to have attractive properties to ANY other material and develope a stong attraction for reasons other than magnetism. ( Like mechanical bonds or tendancy to alloy ). Also perhaps you may not know that non magnetic materials ARE influenced by magnetic eddy currents that cause them to exhibit magnetic like properties. Case in piont, do you think aluminum whould move if you put a magnet over it? Well move it back and forth and see it move. So you see an electromagnet does provide a magnetic field but by turning it on and off so quickly are you not emulating motion. Would therefore non magnetic materials not be drawn with, shall we say the flow? In an effort to attract the non magnetic materials let them be attracted to a non magnetic mass that is 'in the way of eddy currents' but not strong enough to detract from the power of an electro magnetic field for the 'real' magnetic stuff!. Try a rotating aluminum disk with a static closed magnetic field adjacent to it encase in cast steel or machined steel. If you really want to punder the budget, try a rotating plate of depleted uranium instead of something cheaper. Using that you would be able to measure its efficiency by the delta in the residual radiation providing you know the effect of X amount on a control. Well that is it from the ASHMAN! My sence of humor was not appreciated in my past input, as well my intelect seemed to have flown over the heads of those whos job it seems is to judge. I question is this: Can anyone at cr4.globalspec that considers could consider themself at all intelligent ask me a question that I can't answer. NO WAY!

Hey Ash,

As ietech said in post #11, "don't lose your sense of humor! It is generally fun and taken as such by me and most others". I just want to echo that.

Thank You John --- I appreciate the logon or register "guest" part of your post -- I don't necessarily agree with Ashman, it is the Guests that irritate me when they criticize personae non gratis.

Ashman, I'll try to take you up on that challenge: Here's a question that I would like the answer to, if you would be so kind

I would like to know what is the source of the energy that prevents quarks from approaching extremely close to the inside "shell" surface of atomic particles. Say a quark speeds towards the interior surface of the shell of a proton. As the quark approaches closer and closer to the "shell" surface, the repulsive energy grows inversely with the decreasing distance. What is the source of that repulsive energy, and what is it's maximum value? Why are quarks not allowed to exit the "inside" of sub-atomic particles? Will we ever be capable of producing a shower of quarks in a super collider? I would greatly enjoy an informative answer. Thank you.

Hi Cardio-2,

I know the answer to that one but I'll just sit back for now and let Ashman take a stab at it!

Anyhow, thanks for the input.

Ashman,

Use the spell check feature, please. It may not eliminate all of your misspellings, but it will at least make your postings more readable.

Good spelling and good punctuation are the keys to good communicating. It is easy to overlook a few misspellings or missing punctuation in casual, conversational posts, but when you are trying to get across a complex idea or solution to a problem, it becomes very important.

You may not think it is so, but try to imagine a mathematical proof that leaves out a parentheses or uses the wrong arithmetical operator or the wrong Greek letter symbol. That would change things quite a bit, would it not? It would also make it difficult for those reading your proof to understand exactly what you did to arrive at your conclusion, right? It is the same with written language. Spoken language, especially face to face, can be very different and imprecise, but because of facial expressions, tone of voice, body language, etc. and still get the correct message across. Written language must be more precise because it does not have these other qualifiers.

Hi STL Engineer,

I LIKE the way you said that! My feelings exactly.

All readers take heed.

John

But is there enough heed to go around? Did you bring enough heed for everyone?!

Yeah, my pockets are full of the stuff. In small quantities (drops), it might work to separate the glass. In addition to all the heed that's now beginning to spread throughout CR4 (thanks to you) lets also remember:

Oh, Geee!

Since we're on the subject of material, can one of you guys tel me what a whelm is?

Ive been overwhelmed,Ive been under whelmed, but I dont ever recall just being a whelm.

milo

You may think you are joking, but there really is such a word. But it is a verb, not a noun. So you cannot BE a whelm, although you can WHELM something or someone else. From the Merriam-Webster dictionary:

whelm

One entry found for whelm. Main Entry: whelm
Pronunciation: 'hwelm, 'welm
Function: verb
Etymology: Middle English
transitive verb
1 : to turn (as a dish or vessel) upside down usually to cover something : cover or engulf completely with usually disastrous effect
2 : to overcome in thought or feeling : OVERWHELM <whelmed with a rush of joy -- G. A. Wagner>
intransitive verb : to pass or go over something so as to bury or submerge it

Whelm as process. not substance.Ok.

So maybe the micron size particles need to be whelmed prior to separation.

Thanks for the prompt answer. Is their a literary blog like CR4? The only other question I have is why is the book called Moby Dick?

Is that some kind of middle english technical term like "mark Twain?" is a callout for channel depth?

milo inquiring mind today

Well, a quick check of the Wikipedia yields this:

"Two actual events almost certainly inspired Melville's tale. One was the sinking of the Nantucket whaling ship Essex, which foundered in 1820 after it was attacked by an 80-ton sperm whale 2,000 miles (3,700 km) from the western coast of South America. First mate Owen Chase, one of eight survivors, recorded the events as the Narrative of the Most Extraordinary and Distressing Shipwreck of the Whale-Ship Essex. The other event was the killing of the albino sperm whale Mocha Dick in the 1830s. Mocha Dick gained his name because he lived near the island of Mocha off Chile's southern coast. Mocha Dick was riddled with dozens of harpoons from his numerous escapes from whaling ships, which he would often attack with premeditated ferocity. Amazing as Mocha Dick was, one of his battles with a whaler served as subject for a book by Jeremiah N. Reynolds, a book Melville could very well have read as he was doing research for his novel. However, it has also been suggested that knowledge of Mocha Dick came to Melville from his old friend and shipmate Richard Tobias "Toby" Green (his fellow adventurer in Typee) when the two saw each other again in 1846."

Another website has "Melville changed his first name to Moby, probably to suggest his amazing mobility and to avoid association with the "color" mocha."

It could also be (my thoughts here) that "Moby" was derived from the name of his friend "Toby", whose first name Richard, would, conveniently be re-formed as the nickname, "Dick". Thus "Dick Toby", could easily become "Toby Dick", and when blended with "Mocha Dick", could become "Moby Dick".

Mocha Dick gained his name because he lived near the island of Mocha off Chile's southern coast

So why not Mocha Chilly ? Still , the tale is the most plausible I've heard.

Returning to the Question (don't worry folks this will pass, I rarely do this -)

Can you dump the mixed material in a tray , and try for partial separation with a linear motor as in this photo. A well judged air blast may be required to finnish the job.

Nice photos!

One can only imagine the ensuing airquality as a result of this 50 micron dust being herded by air blast.

Kinda makes beijing look like sierra club dream date.

I don't recall that we ever got any definition of the quantities, I was sorta figuring that the ultimate end is an ongoing commercial productin process. So your tray schema would prototype, but the air quality on scale up , well, thats something to ponder.

thanks for bringus back to that original problem.

milo

"So why not Mocha Chilly?"

Because there were no Starbucks around back then!

But seriously (if I ever can be totally!), two possible origins for the name "Dick" as used in connection with celebrity whales; either it is used as term of address, like saying, "Hey, Mack!" or "Buddy", sort of like in the phrase, "every Tom, Dick, or Harry". Since "Tom" was already associated with cats, and whales were not known to be "harry", the name became a natural. Then again, or even together with the above, the shape of a whale might be reminiscent of the shape of the male genitalia also known by the same nickname. And of course size counts!

You inspired me to find this STL . The combination is entirely appropriate given the ingredients sourcing. As I understand it , Aztecs would not recognize modern versions of chocolate. I am not a fan of Mexican dishes incorporating the stuff. A coffee or chocolate drink with chili sounds kind of interesting though.

You probably never tasted a good chicken mole because they saw a gringo coming.

You might be interested in "fire and ice," really good vanilla ice cream topped with Tabasco sauce.

nah. The garlic version sounds icky enough. By tradition , Brits wear a knotted hanky on the head whilst sunbathing. This may be a give-away.

"I believe in bashing two bricks together!"

- Mr. Gumby

Ouch ! In NZ they use their teeth. This wouldn't work for a brit for obvious reasons.

I thought Moby Dick was a morbid disease of the male genitalia!

I'm surprised that no one has caught the "sperm" relation to the name... Let's get with it, people!!!

Interesting. Sperm whales are nothing to mess around with, they're far more aggressive than their baleen-feeding cousins. When biologists are working with sperm whales, they go into the water only after the males have left. Even then, they keep their distance. When the males come back, they usually get the heck out of there!

If some human called me a Sperm Whale because they thought spermaceti was sperm I'd be a bit narked. The ambergris isn't exactly grey amber either. Smells funny to me. Having said that , maybe the baleen dudes get a raw deal with corsets. I bet pearls were once thought to be ova. Better not ask the Japanese to solve the whale problem too loudly , they may want to 'research' it more. Just popping out to get some lino.

Just sayin'

Milo,

It is a far, far better thing to be over the whelm than to be under it! Years ago I was accused of being a whelm but I... ...excuse me, I just need a moment, I was overwhelmed. There now I've recovered. Where was I? Oh yeah, look out! The whelms are coming, the whelms are coming. Run quick, while you can!

Sorry. They wern't whelms after all, they were just Langoliers. Whew!

A.)What is the airspeed velocity of an unladen swallow?

B.) What do I have in my Pocket?

C.) What's your favorite color?

Let me try! Pick me! Pick me!

Can I try? CanI? CanI?

PuLLeeeeze?

A) It would vary between 6.3 and 21.3 cm/s (mean, 10.5) in human tissue, depending on age: http://www.springerlink.com/content/rr22612v06186219/. Speed of peristalsis, is constant and not influenced by bolus volume. http://www.springerlink.com/content/q3402v97h2451hgr/

Swallow cannot propogate in air, so airspeed is incorrect unit. Velocity is correct as peristalsis is a vector, anti peristaltic actions are multiples of standard peristalsis rate.

B) Clinging bits of fiber and fluff; fuzz supervened by a laminar containment of a colorless, hopefully odorless, gaseous mixture, predominately nitrogen, particulate matter (primarily of fibrous and cutaneous origin) and moisture, with lesser amounts oxygen as well as minor amounts of other gases. C) The ones visually associated with 665 nm and 465 nm. Without these, none of us would be alive. While stated preference may differ, the ability to state that preference would be nonexistant, so these are favorite axiomatically. (absorption peaks of Chlorophyll. milo

milo " my idea of pop culture is getting a 44 oz Pepsi fresh out of the fountain at Speedway"

Oh, you really should see the "Shrek" movies. From the Marvelous Mind of Mike Meyers (who gave the world "Austin Powers"). "Shrek" and its clones (Shrek 2, Shrek 3-D, which was actually a short produced for Universal Studios theme park as "Shrek 4-D", and now Shrek the Third) are marvelous send-ups of classic "Fairy Tale" creatures and stories, just as "Austin Powers" took pokes at all the "James Bond" movies. The great thing about Shrek (a big green Ogre, think of "The Hulk" from the comic books, with no hair and weird ears, who likes to fart and scare people at will, but is really a very nice guy, once you, or Donkey, gets to know him.) is that the movies work at both a kid level, and at an adult level (well, for the kid in you, of course!).

I think Fungus pre-dates Shrek. The Author has some brilliant books (look out for When the Wind Blows) , and the screen version of Fungus is very good. The principle is the same (kids/adults appeal at different levels of meaning). When the Wind Blows is a must - funny/tragic etc etc all at the same time.

I am unfamiliar with Fungus. Obviously another British Trade Secret, not for American consumption. It seems we usually import the British Ideas, re-cast them with American actors, then occasionally export them back to Britain and the rest of the world as "American Pop Culture". Is Shrek another Anglo-Import? Compared to Fungus it seems more original and focused on the Fairy Tale aspect, rather than just being gross.

Interesting that Meyers does Shrek with his patented (if not totally authentic) Scottish accent. Are Ogres native to Scotland? The other characters for the most part seem to have (to my Midwestern American ears) no particular accent, except for the Prince Charming character, voiced marvelously alternatively charming and malevolent, by the underrated Brit, Rupert Everett, who does the British Upper Crust accent very convincingly (his native tongue?). And of course Antonio Banderas has Puss In Boots as a Spanish-accented Latin Lover/Cavalier-type, a la Don Juan.

On the other hand, we also have Brits Julie Andrews and John Cleese as the King and Queen (respectively? ) of the Land of Far Far Away in Shrek 2 and Shrek the Third. And Eric Idle as Merlin and Ian McShane as Captain Hook in Shrek the Third. But casting against type, or accent anyway, we have Justin Timberlake as an American (future King) Arthur, Robin Hood and his Merry Men are FRENCH!

Oh, no! IMDB shows Shrek 4 is in production for 2010. Or is that just a really good joke being played by Mike Meyers? Here is an excerpt from IMDB. Judge for yourself:

"Peter Zaslav said in an interview that the Christmas special Shrek the Halls will pickup from where Shrek the Third left off. The film will also be followed by another sequel, Shrek 4, which will be released in theatres in 2010. In an interview with Antonio Banderas, he has said they are making a fifth Shrek and a Puss In Boots movie entitled Puss in Boots: The Story of an Ogre Killer."

And, is it just me, or does this Smiley look a lot like The Gingerbread Man?

OK, back to Magnetic Separation of Material.

"Just curious, what branch of engineering studies "Fungus'" and "Shreks"?

Good question, Johnjohn (with a name so nice, you have to write it twice?) I would say, that since these are Imaginary (Fairy Tale) characters, and there is one branch that "Imagines they are Engineers" (IE's!),...well, draw your own conclusion!

Wait, maybe these are Weights and Measures, i.e. How many Shreks to the Fungus? If we have Furlongs and Fortnights, Newtons and Watts (Sir Isaac and James), etc. why can't we have Shreks and Fungus (Fungi?).

Let's define a Shrek as being the Weight of one standard Ogre at Swamp Level, before breakfast. How many Fungus/Fungi would that be?

Now just "weight" a minute S.

We can't define a Shrek before breakfast because before breakfast the Ogre particle has no mass and thus not enough subtance to be quantified.

A Shrek has no shame.

OTOH a Fungus however...

Or thrice, johnjohnjohn

Brittle splatter.

milo

Yeah , fungus is pretty unknown. Shrek bears more than a passing resemblance (we Brits like to gripe about such things) - I'm not sure of his origin now that you've mentioned it. Kinda like Thunderbirds was British , but had to be done with American accents to get production backing ( he he , now I've done it ) - It's true , honest. Fungus is a misjudged creature (not unlike Quasimodo in some ways). I've never watched all of Shrek , but it looks brilliant from what I have seen. If you find When the Wind Blows on ebay or some place you'd like it . Brit culture /humour exposed in a very chilling Thermo-nuclear setting. True civil defence instructions are lampooned without mercy (the book Protect and Survive was issued by the Government. It had such gems as 'put on a stout pair of boots and go outside to see what has happened' , 'paint the windows white if an attack seems likely'). Spiffing as Brits would say in those days (but only if upper class/public school).

looks more like 'The Scream' with Botox.

(-the unimaginable)

Someone once asked if the character in The Scream is actually screaming or covering his/her ears because someone else is screaming.

Ours is traditionally bright yellow , thick enough to skate on , and contains more sugar than should be possible.

It emerges from a serving jug in gloopy gelatinous blobs , usually to coat a similar pudding.

This really blows me away, but I'm told that in the fifties, a nation-wide advertising campaign sold "A Moon-Pie and an RC Cola" as the "Working-man's lunch!!!" How foul is that?

I would like to know the materials you are separating and the amounts of each. I would suggest using a dust cyclone to separate the heavier material from the dust. The heavier material is extracted through the bottom and the dust is blown out through the top of the cyclone. Dust cyclones come in many different sizes so one should meet your needs. Oh, when I was in the Coast Guard, we used a liquid centrifuge to separate the water from the diesel oil before putting it into the engines. Maybe you could incorporate your slurry into a used centrifuge from a used ship salvage supply to separate the two materials.

If the slurry is helping, try adding some detergent (NOT SOAP) to the mix, that may take care of any ions hanging around. Just a thought.

They contain Iron, Nickel, Cobalt, copper, Manganese, Aluminium in varied proportions along with acid insoluble material like silica, silicates etc. Particle size distribution varies drastically but could be classified. We are basically talking about particles of around 300 micron to 100 micron size.

Why so fine?

seems like overkill for commercial tonnages.

Arun 54,

Seeing the diversity of responses that you´ve got, seems to me some not at all professional, and given the complexity of the problem posted perhaps you´d better take your inquiry elsewhere. You can find people that know about powder processing and handling at www.bulk-online.com; register in The Forum and fire your question. Do please post back here when you have feedback on your problem so we all can learning something.

"Given the complexity of the problem posted"

Actually, given the paucity of facts.

With out giving specifics of materials involved, or otherwise attempting to share any meaningful 5W-2H' s of the process, we are all forced to observe Ashman and others pull off their 'Karnac the Great' skits of omniscience. Incomplete problems ALWAYS yied a diversity of responses because they lack specifics. It isn't the CR4 forum thats the root cause.

milo "i always sign my posts"

Very well put it is near impossible to give best advice to some one who neglects to specify any meaningful information, any answer is just an educated guess.

What do you mean by 5H-2H?

You´re right, of course. I enjoy wit as much as the next guy even if it sidetracks the issue at hand. However the party that posted the questions is none the wiser.
