Magnetic water conditioner/Halbach Array

Regularly we see a magnetic water conditioner including two magnets with opposite magnetic poles face-to-face cliped together, just simply clip them together onto the water pipes will get a magnetized water resulting from flowing water cutting the magnetic filed. The advantages are low cost and simple operation but the only disadvantage is weak magnetic field due to attraction by those two magnets. When using this device, we have to pay attention that better clip it to the plastic pipes or stainless steel or copper pipes but not on iron pipes.

               

The magnetic water conditioner with single magnetic pole technology is of higher effecient and bigger room of application. While as we all know it is rather hard to achieve single side magnetism, for all magnets are with two oppisite magnetic poles, so we have to achieve it by some special design and structure. The structure is based on some particular magnetic array to achieve concentration of magnetic force, it will get better penetration in compare with normal two poles magnets. As follows is a Halbach array that will help us to get single side magnetism by concentrating magnetic force on one side. According to actual application, we can range magnets in a line and in a circle.

           
                                                  (bar halbach array)                                             (circle halbach array)

For Bar halbach array and circle halbach array we can findout the magnetic field distribution respectively as follows:

      

From the above photos we can findout that if we use circle halbach array, 90% magnetic force can be concentrated inside the circle, this will get better water magnetization. The magnetic water conditioner with this technology has much higher efficient and powerful cleaning ability, especially in agriculture, it has much bigger room than regular magnetic water conditioner.

MaximMAG is able to make every kind of Halbach Array in straight line or circle forms, welcome your inquiries to SALES.

Neodymium magnets for Wheel-hub motors

You may come to know nowadays China is no longer a country of bicycles but a country of electric-scooters or electric motor-cycles, because no matter you're in 1st tier cities such as Beijing/Shanghai/Guangzhou or 6/7/8 tier cities, you can find yourself envolved in a mass crowd of electric-sceeters and hardly find enough space for automobiles to squeeze into. 

   

（from blog.sina.com.cn)

Just because of such kind of savage growth of electric-scooters, the requirments of Neodymium Magnets from this industry boomed, however, as every other new innovative and propective industry of low entry threshold in China, manufacturer of electric bicycles enter a fierce competition of price period of times, so now you can easily find piled of non-coated small block magnet blanks in small factories of NdFeB magnets ready to deliver to assembly lines of those manufacturers of electric bicycles. "Why non-coated" you may ask "they must be corrode without any coating to protect it", yes, it's because of the cost.

Penn Research Simplifies Recycling of Rare-earth Magnets

Despite their ubiquity in consumer electronics, rare-earth metals are, as their name suggests, hard to come by. Mining and purifying them is an expensive, labor-intensive and ecologically devastating process.

Researchers at the University of Pennsylvania have now pioneered a process that could enable the efficient recycling of two of these metals, neodymium and dysprosium. These elements comprise the small, powerful magnets that are found in many high-tech devices.

In contrast to the massive and energy-intensive industrial process currently used to separate rare earths, the Penn team’s method works nearly instantaneously at room temperature and uses standard laboratory equipment.

Sourcing neodymium and dysprosium from used electronics rather than the ground would increase their supply at a fraction of the financial, human and environment cost.

The research was lead by Eric J. Schelter, assistant professor in the Department of Chemistry in Penn’s School of Arts & Sciences, and graduate student Justin Bogart. Connor A. Lippincott, an undergraduate student in the Vagelos Integrated Program in Energy Research, and Patrick J. Carroll, director of the University of Pennsylvania X-Ray Crystallography Facility, also contributed to the study.

It was published in Angewandte Chemie, International Edition.

“Neodymium magnets can’t be beat in terms of their properties,” Schelter said. “They give you the strongest amount of magnetism for the smallest amount of stuff and can perform at a range of temperatures.”

These thermal qualities are achieved by mixing neodymium with other elements, including the rare-earth metal dysprosium, in different ratios. Because those ratios differ based on the application the magnet is being used for, the two metals need to be separated and remixed before they can be reused.

“It’s, in principle, easier to get the neodymium and dysprosium out of technology than it is to go back and mine more of the minerals they are originally found in,” Schelter said. “Those minerals have five elements to separate, whereas the neodymium magnet in a wind turbine generator only has two.”

Currently, whether purifying the neodymium and dysprosium out of minerals or out of an old power tool motor, the same costly and energy-intensive process is used. The technique, known as liquid-liquid extraction, involves dissolving the composite material and chemically filtering the elements apart. The process is repeated thousands of times to get useful purities of the rare-earth metals, and so it must be conducted on an industrial scale.  

Rather than this liquid-liquid method, Schelter’s team has devised a way to separate the two metals. 

"When we started," Bogart said, "our goal was to make rare earth separations simpler and more efficient and we have made strides towards just that. We have designed a way to separate the two metals by selectively dissolving the neodymium in a solution and leaving behind the dysprosium as a solid. This quick and easy method has allowed us to separate equal mixtures of the metals into samples that are 95 percent pure."

Their method can, in a matter of minutes, separate an equal mixture of the two elements into samples that are 95 percent pure.  

Starting with the two elements as a mixed powder, a metal-binding molecule known as a ligand is applied. The type of ligand the research team designed has three branches, which converge on the metal atoms and hold them in the aperture between their tips. Because of neodymium’s slightly larger size, the tips don’t get as close together as they do around dysprosium atoms.    

“The difference in size between the two ions is not that significant, which is why this separation problem is difficult,” Schelter said, “But it’s enough to cause that aperture to open up more for neodymium. And, because it is more open, one ligand-neodymium complex can combine with another, and that really changes its solubility."

The combination of the two neodymium complexes, known as a dimer, encapsulates the neodymium ions, enabling them to dissolve in solvents like benzene or toluene. The dysprosium complexes do not dissolve, enabling the two metals to be easily separated. Once apart, an acid bath can strip the ligand off both metals, enabling it to be recycled as well. 

"If you have the right ligand, you can do this separation in five minutes, whereas the liquid-liquid extraction method takes weeks,” Schelter said. “A potential magnet recycler probably doesn’t have the capital to invest in an entire liquid-liquid separations plant, so having a chemical technology that can instantaneously separate these elements enables smaller scale recyclers to get value out of their materials."

Future work will involve improving the stability of the ligand so it is less likely to fall off before the metals are separated.

"These results are encouraging," Bogart said. "We feel that through slight adjustments to the system, the purity level could be increased even further."

Further modification of the ligand could enable other rare earths in technology products, such as compact fluorescent light bulbs, to be recycled this way.

The research was supported by the Early Career Research Program of the U.S. Department of Energy’s Office of Science and the Research Corporation for Science Advancement.

Lynas CEO Digs In as Rare-earth prices Slump

Lynas CEO Digs In as Rare-Earth Prices Slump
CEO Amanda Lacaze says it is time for Lynas to invest more in sales and marketing to grow the business

SYDNEY—As rare-earths miner Molycorp Inc.  looks to wind down production at its U.S. mine,  Lynas Corp.  Ltd., the only other producer outside of China, hopes to do the opposite and raise its output of elements used in batteries, magnets and other high-tech products.

To accomplish that goal, the Australian-listed miner plans to do one crucial thing: “Go out there and sell,” said Chief Executive Amanda Lacaze, in an interview.
Lynas, a former market darling, has found it tough to become a major competitor in the global rare-earths market.

The company was founded with an eye to breaking China’s stranglehold on the industry: The world’s second-largest economy has accounted for more than 90% of world-wide supply in recent times. But it took nearly a decade of development before Lynas began operations at its refinery in Malaysia’s Pahang state in late 2012.

Start-up of its processing plant in Malaysia was delayed by repeated legal challenges, and the ramp-up of the plant has since been hindered by technical setbacks and a relentless tumble in rare-earths prices.

Now, after working through reliability issues at its processing facility and restructuring its debts, Ms. Lacaze says it is time for Lynas to invest more in sales and marketing to grow the business.

“When this company was conceived, the idea was: Build it, and they will come,” she said. “But Lynas was born when prices were high, and the market has well and truly moved on.”

Lynas—which currently sells most of its resources to customers in Japan—intends to pursue wind turbine manufacturers in Europe and auto makers in North America as part of an aggressive strategy to widen its customer base. It also plans to court more Japanese customers, specifically for its lanthanum and cerium products, used in petroleum refining and catalytic converters respectively.

‘Lynas was born when prices were high, and the market has well and truly moved on.’
—Lynas Chief Executive Amanda Lacaze
 .
Last month, the miner announced a restructuring of its long-term debts, including extending the time it has to fully repay the loans. Ms. Lacaze said that was a pivotal moment for the company, which is now valued at roughly 135 million Australian dollars (US$96 million) versus A$3.5 billion just a few years ago when rare earth prices peaked.

She said many manufacturers had cut rare earths from their products when prices ballooned five years ago -- after China restricted its exports -- but hadn’t yet reintroduced them despite sharp price declines.

“Now we need to convince end-users we are stable and financially viable, and that it is time to engineer rare earths back in,” Ms. Lacaze said.

The end of one of the biggest commodity bubbles in economic history recently pushed U.S.-based rival Molycorp to file for chapter 11 bankruptcy protection and suspend its Mountain Pass mine on the California-Nevada border.

Lynas has been slashing costs to keep afloat. That has included layoffs and relocating its headquarters to Malaysia from Australia, in what Ms. Lacaze—who took the reins of the company 14 months ago—described as “effectively a turnaround of a startup.”

At full steam, Lynas’s Malaysian facilities could produce up to one-fifth of annual global output, according to previous company estimates.

Ms. Lacaze said she now expects that Lynas can push the Malaysian plant to full capacity—22,000 metric tons—by 2017. The company projects output above 3,000 tons this quarter, from about 2,600 tons the quarter prior.

To be sure, hitting that long-run target rate won’t happen if demand remains weak.
“I am not of the mind to use up our resources to sell at low prices,” she said. “But we are certainly comfortable that it can be achieved.”

Rare earth Upstream over-capacity exacerbate, the industry calls for strengthening management on sources

          On the 7th China Baotou rare earth industry forum, an insider pointed out that the rare earth upstream over-capacity has exacerbated in last five years, this has greatly effected the healthy development of the industry, in order to turn the tables strengthening management on sources is a must.

         Mr. Chen zhanheng, Vice Executive secretary of Association of China rare earth industry, said that over-capacity had long troubled the development of rare earth industry in China, before 2011 the capacity of the rare earth upstream products was from 0.18 million to 0.2 million tons, while when it flurished in 2011 and an investment boom in rare earth was happened, the capacity reached 0.3 million tons just at the end of the year 2011. An estimated 0.4 million tons rare earth upstream products' capacity was reached in 2014.

 

         Mr. Zhang anwen, vice executive secretary of Chinese Society of Rare Earths, said excessive competition due to large capacity of upstream products currently is seriously affect healthy development of the industry. For example: from July of 2011, our rare earth products experienced continuously falling on prices, most products' prices has fallen more than 70%, some even more than 80%. Currently lot of key rare earth companies are at a loss.

 

         The insider point out that over-capacity exacerbation is one of the main reasons why the rare earths' prices still goes down under an environment of continuous integration of rare earth industry. It is suggested that at the same time of pushing forward industry integration and intensify fighting against rare earths "black industry chain" , management on rare earth mining should be further strengthened.

Permanent magnet synchronous traction motor magnets

Using high-performance rare earth permanent magnet materials, no carbon brushes, permanent magnet synchronous gearless traction machine can drive efficiency up to 90%. It effectively improves the energy efficiency with energy saving, environmental protection, low speed and high torque characteristics. Gearless traction machine can be dividedinto the inner rotor and outer rotor based on the rotor structure, while permanent magnets stick to these rotors.

Due to the special work environment of the elevator, it is possibility that magneton the motor will demagnetize after prolonged use, for example:
1. Unqualified rare earth permanent magnet;
2. Unsaturated magnetization;
3. Motor working temperature exceed magnet permitted range;
4. Long oxidation of rare earth permanent magnet;

In orderto avoid the above situation occurs in practice, the elevator magnets needs careful and meticulous design and manufacturing. Magnet design also needs to consider magnet size, magnetic properties and the worst working conditions of motor. It is better that the magnetic properties are higher than the practical requirement. Before installation, rare earth permanent magnets should pass high temperature aging test and saltspray test.

For a long time, elevator manufacturers use bonding process to fix permanent magnets on the rotors. Theoretically, using glue and magnetic force, it could be okay. But In some cases magnets will tear off because of high temperature or other reasons. To reinforce magnet on the rotor and reduce the problems caused by magnet dropping, it can combine screws and adhesive binding by making a countersunk on the basis of simple block or arc magnets.
