Off-White x Nike Air Force 1 White and Black release during Summer 2017

31/01/18

Fist One OFF-WHITE Nike Air Force 1 Low White,The OFF-WHITE x Nike Air Force 1 Low collaboration is apart of the 10X Collection which is expected to release during Summer 2017.

Just before Game 3 of the NBA Finals, both LeBron James and Kevin Durant was seen wearing the OFF-WHITE x Nike Air Force 1 Low White collaboration which gave us a preview of what’s to come.

Streamlining with everything else we have seen with OFF-WHITE, this Nike Air Force 1 Low features an unfinished theme. Prior to this we have seen a Black version, but it appears that the retail release will come in predominate White. Metallic Silver lands on the Nike Swoosh which shows stitching. The laces will have ‘SHOELACES’ across them while ‘AIR’ in Black is seen on the midsole. Completing the look is the Nike branding on the tongue done in Red off to the side.
Nest One is  MoMA x Virgil Nike Air Force 1 ’07 Black

Virgil Abloh is expanding on his collaborations with Nike Sportswear but this time he will also be linking up for MoMA which stands for Museum of Modern Art. Located in Midtown Manhattan in New York City and designed by Yoshio Taniguchi, the trio will debut the Nike Air Force 1.

This OFF-WHITE x Nike Air Force 1 Low collaboration looks like your standard collaboration with Virgil. For this pair they come dressed in Black and Metallic Silver. As for MoMA’s part, what stands out is their name on the box label.

The OFF-WHITE x MoMA x Nike Air Force 1 in Black was first spotted at Art Basel and now it will release soon part of the upcoming exhibit at The Museum of Modern Art. You can also see a short video below of Virgil Abloh designing a pair for MoMA’s Senior Curator of Architecture & Design and Director of R&D Paola Antonelli. In addition a pair of matching socks will be included in the release on 2018jordans.com

2018 Jordan Why Not Zer0.1 Performance Review

24/01/18

It has been a long time since Jordan Brand blessed an athlete with a signature shoe; the last one was Chris Paul, and he is on shoe number 10. 10 years and no new blood on the market. What is a brand to do? Well, since it already has the reigning MVP on the roster, how about dropping a line for his feet.

With the plan in place, we give you the Jordan Why Not Zer0.1 Performance Review. Let’s go…

From the pattern alone, this traction should be like Peter Parker — sticking to things you don’t even really want to. It’s comprised of multi-directional blades broken into nubs running from a center line right in the middle of the forefoot. The blades should push dirt away and out while gripping the floor, and they did a great job — as long as the floor has at least a little finish on it.

On the first court I played on, I was sliding everywhere, having to wipe about every second or third trip down the floor. Granted, the floor was dirty and sucked, but you encounter all kinds of courts in life. The second floor was in better condition, and the traction was way better. Yeah, wiping was still needed, as the traction is shallow and does pick up dust (could be the translucent — I haven’t had a chance to try the solid rubber yet), but when clean and the court is workable, you’re straight Gorilla Glue.

Outside courts: don’t do it. Just don’t.

Technology-wise, the part of the Jordan Why Not Zer0.1 that has everyone’s eye is the cushioning. Full-length Zoom runs bottom-loaded and at 8mm thick it has bounce while still being low-riding. The Phylon surrounding the unit? That’s definitely going to need a little time to break that in.

The midsole felt very much like the Jordan 32, from the start and once broken in, but once it gets going and starts creasing you will get a responsive rocket ride that is low enough for quick guards and won’t hurt when you land. Zoom has been around for over 20 years, but when done right, there are very few cushioning systems that can compete with it in the basketball market.

The materials used on the Why Not Zer0.1 aren’t exactly premium, as the upper is mesh and fuse, but the way the lines are cut and layered, it works. The inner bootie is open mesh and feels great on-foot — no hot spots or harsh rubs to cause blisters — even though the ventilation is terrible and the upper fits tightly all around your foot (usually, when you combine those two traits, blisters come next).

The lacing system uses the Flightweb system that is almost exactly the same as the Air Jordan 29 under the fuse cover. Speaking of the cover, you get a thin fuse that has no stretch at all over the foot. It’s great for containment, bad for sweaty feet, but those graphics…Jordan Brand could change the whole perception of this shoe with printed graphics on the cover.

The heel counter is stiff foam and never really broke in while wearing. It was good for support but bad for getting your foot in the shoe. On the plus side, the counter/heel is lined by some seriously thick padding that helps with lockdown and keeping that counter from rubbing your ankle until you bleed.

Lastly, the tongue is 3M and the “Why Not?” graphic should be on the outside (it needs to be seen). Overall, nothing new in the materials, but dang they work.

This is serious: the fit in the Why Not Zer0.1 is almost better than Hall of Fame. What could be better? Hall of Fame plus 1? Who knows, but once your foot is in the shoe, there is no movement at all. NONE.

The length is a little long, but not enough that it affects performance (and I like a little extra length). The width is perfect for normal to semi-wide feet (mine are slightly wide), and the heel counter completely locks your ankle and rear foot in place.

The laces are a quick-pull system using the Flightweb integration and completely pull the inside mesh onto the foot. The heel counter is lined with thick padding, as is the ankle area, and it is that old-school wrap-around-the-joint-and-lock-you-in feeling.

The strap, well, it looks good, but it isn’t really needed. The Why Not Zer0.1 has internal wings that pull inside and lock in, so the strap is just extra overlay to hide the construction. Same with the foot sleeve — the graphics look great and it hides the lacing, but like the original Zoom Flight “the Glove” and the Air Jordan 28, the cover is aesthetic.

Getting into the shoe presents problems until you figure out a method. That’s completely insane, to have a “method” to get a shoe on, but ever since the KD 10 it has been more necessary than not. The stiff heel counter comes all the way to the top of the shoe and has little give. The cover has no stretch, meaning the tongue doesn’t pull out very far. Add these together, and your foot almost has to be greased to get in.

Luckily, after the first couple wears the foam in the ankle collar loosens slightly and your foot should go in way easier. If not, keep pulling and tugging — once in, the fit is like almost no other shoe out there.

Like Fit, Support is an excellent category for the Why Not Zer0.1. That heel counter, again, is big, solid, and imposing — it’s actually kind of scary. The looks lead you to believe the shoe is stiff and rollerblade-y, but the counter cuts away from the ankle joint as it rises, leaving some room for linear (straight forward) motion as you run. The strap does lock in but it’s soft and flexible, and the cut-out under the ankle strap lets you bend and move easily.

The midfoot/forefoot is supported by the lacing and the cover — and you aren’t going off the footbed in either direction. The Phylon midsole rises up over the sides of your foot to hold you tight and as it approaches the sole it flares out dramatically to give the Zer0.1 one of the largest outriggers ever.

However, it isn’t clunky; the way the tooling is molded offers a natural feel (with the edge being rounded and not cut off sharply). You really don’t notice it until you look down and see how wide the shoe looks from the top.

There is no shank plate but the sheer amount of Phylon and Zoom keep you from bending the wrong way. Don’t be scared — no shank plates could be found in shoes until ~1995 anyway. As long as the shoe doesn’t bend in the toe-to-heel direction at a drastic angle, you should be okay.

All of this structure must mean the Why Not Zer0.1 feels clunky and slow on court, right? Not at all. The transition is smooth and clean with responsive direction changes and quick jump. The full-length Zoom gives the foot a consistent platform through your step and the low ride feels fast and light.

That was a lot of words, but when a shoe is this good, words are hard to stop — just like Brodie. Westbrook has had a reputation of having a hard time finding a shoe he loves, but the Why Not Zer0.1 should fit all of his needs.

If you are looking for great fit and support, great cushioning, and (almost) great traction, you have got to check this shoe out. This is what Jordan Brand was known for when it was building a name — performance and polarizing looks. Every year, the Jordan shoe was u-g-l-y, until Mike wore them. Then everyone loved them and a legend was born.

The Jordan Why Not Zer0.1 starts off looking completely different from the other shoes on the shelf, but let the performance speak and the shoe will be proven. From guards to big men, the shoe just works. It is a basketball players shoe, and it does everything on court that a shoe should do. Kind of like a certain #0 in OKC, huh? Now it makes sense.

why raymond mill is welcomed

19/01/18

Nowadays, the economic construction of our country is in full swing. The development of the mining machinery industry is also very rapid. With the ever-changing market demand, the design of raymond mills more intelligent, automatic production operations have become the mainstream. Among the many types of mill, Raymond mill has a good user experience, in line with the needs of modern production, is widely used in small and medium-sized mining, chemical, building materials, metallurgy, refractories, pharmaceuticals, cement and other industries.
Horizontal raymond mill mainly by the rack, into the air volute, blade, grinding roller, grinding ring, the shell and the motor and other components. Roller device suspended in the host plum-frame for rotation and rotation movement, due to the role of centrifugal force during rotation, roller swing outwards, pressing on the grinding ring. During operation, the material enters the machine body through the feeding hopper on the side of the machine shell, shovels from the blade to the between the grinding roller and the grinding ring, and reaches the grinding purpose under the rolling of the grinding roller.

Raymond mill to create potassium feldspar

18/01/18

Potassium Feldspar may not be well-known to people who are not related to the industry. Mention may be made of the term ‘potash.’ As the main element of fertilizer to help crop growth, it is only common use of potash feldspar According to the statistics of available data, 50% -60% of potassium feldspar is used in the raw materials of the glass industry and 30% is used in the production of ceramics. Raymond mill plays an important role in the ore processing of potash feldspar , A direct impact on the late use of stone powder in various industries.
The above-mentioned application of potassium feldspar powder on the fineness requirements are not very high, under normal circumstances is below 400 heads. In accordance with the normal crushing mdash; milling grading mdash; dehydration mdash; stone powder production process can reach the material standards. But one very important thing is to pay attention to when preventing potassium feldspar from being contaminated. Therefore, the selection of Fujian mill manufacturers, we must understand that their milling equipment can be fully enclosed operation.
To avoid being contaminated with potassium feldspar, the choice of fully enclosed milling equipment, of course, to conduct a full inspection of the manufacturer. In addition to the first factor affecting the price of Raymond mill, which is a cost input, the more important one is the in-depth analysis of the mill’s structure. Shibang Raymond mill is a high-efficiency, closed-circuit high-density milling equipment that replaces the ball mill. As an advanced equipment with high-pressure milling, the throughput per hour is 1.2-11t, creating the myth of potassium feldspar powder.
In order to get the best powder, potassium feldspar production line should choose Raymond mill. This is a milling equipment for standalone production systems that can be integrated from raw material roughing to conveying to milling and final packaging, saving time and effort. In June 2013, a potassium-feldspar flour mill in Fuzhou purchased 10 Raymond mill machines from the World State Council and operated daily for up to 11 hours to achieve the production of potassium feldspar ultrafine powder of 300-600 mesh.
