The ribbon mixer machine is generally used for the mixing of viscous or cohesive powder particles and the mixing of liquid and paste materials added to the powder particles. At the same time, due to the difficulty of cleaning viscous materials, it is suitable for the mixing of large output and infrequent variety change.

Structural features of spiral ribbon mixer

The spiral ribbon mixer is composed of a U-shaped container, screw belt mixing blade, and transmission parts; U-shaped long cylinder structure ensures the small resistance movement of mixed materials (powder and semi-fluid) in the cylinder. The positive and negative rotating screw bars are installed on the same horizontal axis to form a low power and efficient hybrid environment. The screw belt blades are generally made into two or three layers. The outer spiral collects the materials from both sides to the center, and the inner spiral transports the materials from the center to both sides, which can make the materials form more vortices in the flow. The mixing speed and uniformity are increased.

Application of spiral ribbon mixer

Horizontal ribbon blender is widely used in the mixing of putty paste, real stone paint, dry powder, putty, medicine, food, chemicals, feed, ceramics, refractories and other solid-solid (i.e. powder and powder), solid slurry (i.e. powder and glue liquid), especially for the mixing of viscous materials. The mixer is not suitable for materials with large fiber content and density difference. For the putty paste, real stone paint, biology, medicine, food and other industries, stainless steel is recommended. In general, the horizontal screw belt mixer is recommended for mixing the dry powder sand slurry containing vitrified beads.

Cylindrical Lens can be used in a single axial convergence or divergence of the beam and found in optical measurement, laser scanning, spectroscopy, laser diode output beam shaping, the X-ray light microscopic imaging, and many other industries and fields have a wide range of applications.

Turn the quasi-direct light source into the line light source

L = 2(r0/f)(z+f)

It is the most extensive application of cylindrical lens. As shown in the figure below, The quasi-direct light source with radius r0 is irradiated into a concave cylindrical lens with a focal length of -f(The image is in order to illustrate the principle more clearly, so amplify the beam radius). The beam will diverge in half theta (theta = r0 / f). At this point, it can also be approximated as the divergence of the point source at the focal point -f. The distance to the back of the lens is z. The width of the line beam is 2r0 (ignoring the divergence of the  Gaussian-distributed beam spot), but the length of the line beam is changed

L = 2 (r0 / f) (z + f)

When z is greater than f, the expansion ratio approaches z/f, and the length of the line is proportional to z.

If need in the z produces width is very narrow line light source, can be in the plane concave cylindrical lens front end or back end of a flat convex cylindrical lens focal length for z, with the orthogonal plane concave cylindrical lens place, to compress the beam width.

【 Quick Start】The focus and alignment of light

The diode outputs beam of collimation

The laser diode output beam diverges in an asymmetric form, and its quasi-direct work is more challenging. for example, to divergence angle theta. Theta 1 x 2 = 10 ° x 40 ° diode light source, if only use the standard spherical lens, and only in a single direction on collimating, another direction divergence or convergence will happen. Using a cylindrical lens that the problem is decomposed into two one-dimensional directions, through the combination of two orthogonal cylinder lens, two directions can be collimated at the same time.

The selection of the cylindrical lens and the installation of the light road should follow the below rules:

θ1/θ2 = 10°/40° = f1/f2

1)To make the spot symmetrical after the adjustment, the focal length ratio of the two cylindrical lenses is equivalent to the divergence angle.

Theta 1 / theta 2 = 10°/ 40° = f1 / f2

2）The laser diode can be approximated as a point source, to get the collimating output, The spacing between the two cylinders and the light source is equal to the focal length of the two.

3）The spacing between the main planes of the two cylinders should be equal to the difference between the focal length of the f2-f1, and the actual spacing between the two lenses is equal to BFL2 - BFL1. Like the spherical lens, the convex side of a cylindrical mirror should be directed toward a quasi-direct beam to minimize as much as possible.

d1 = 2f1(tan(θ2/2))

d2 = 2f2(tan(θ1/2))

4）Because the laser diode output beam diverges faster, we need to be careful to confirm that the spot size on each cylinder is no longer than the effective light aperture of the lens. Because the distance of the cylinder is equal to its focal length, the maximum spot width of each cylinder should be followed

D1 = 2f1 (theta 2/2)

D2 is equal to 2f2, the tangent of theta one half.

For example, Newport CKX012 (f1 = 12.7 mm, BFL1 = 7.49 mm) and CKX050 (f2 = 50.2 mm, BFL2 = 46.03 mm) the combination of cylinder lens, the spacing between the two lens on the plane for BFL2 - BFL1 = 38.54 mm. The diameter of the spot in the first cylindrical lens is

D1 = 2 (12.7 mm) tan (20 °) = 9.2 mm

The diameter of the light spot in the second cylinder is

D2 = 2 (50.2 mm) tan (5 °) = 8.8 mm

Although there is still a little asymmetry, the simple combinations of these two cylindrical lenses have greatly improved the quality of the beams.

The paddle agitator has the simplest structure. The blades are made of flat steel, welded or fixed on the hub with bolts. The number of blades is 2, 3 or 4. The blade forms can be divided into flat blade and folded blade. That is to say, according to the shape and characteristics of the blades, it can be divided into flat blade agitator and inclined blade agitator. The horizontal agitator produces radial force while the inclined agitator produces axial force. The paddle agitator is suitable for mixing low viscosity liquid, suspension and solution.

Application of paddle mixer machine

1. In the liquid-liquid system, the paddle mixer machineis used to prevent separation and make the tank temperature uniform. In the solid-liquid system, it is mainly used to prevent solid settlement.

2. Paddle type mixer is mainly used for fluid circulation. Because of the same displacement, the power consumption of the folded blade type is less than that of the flat blade type, and the operation cost is lower, so the axial flow blade is used more.

3. It can also be used to stir high viscosity fluid, promote the up and down exchange of fluid, replace the high price spiral belt impeller, and obtain good results.

Precautions for maintenance of paddle mixer machine

Regularly replenish lubricating oil for reducer and chain, grease for main shaft bearing and door opening bearing;

The chain should always be tightened slightly, otherwise, the loose chain is easy to cause jumping teeth, blade fighting, and other failures, resulting in unnecessary losses;

Check and supplement the lubricating oil in the oil mist eliminator of the pneumatic system regularly, and check the water collection in the air-water separator to ensure that the water level in the tank does not exceed 80%;

Check whether there is air (oil) leakage in the pneumatic pipeline and interface, if any, replace the air pipe or plug in the connector again;

Check the mixer rotor regularly and remove the sundries such as braided tape, nylon thread head, etc;

Check whether there is leakage at the shaft head of paddle agitator mixer frequently. If there is leakage, tighten the gland bolt slightly, and replace the packing after the packing is worn out. Check the four corners of the mixer door frequently for leakage. If there is leakage, adjust the support of the door arm and tighten the screws.

Powder mixer machine   is a mechanical device that uniformly mixes two or more materials by mechanical force, gravity, and the like. In the process of mixing, it is also possible to increase the surface contact area of the material to promote the chemical reaction; it can also accelerate the physical change.

Types of machine mixer powder   Commonly used powder mixer machines are divided into gas and low viscosity liquid mixers, medium and high viscosity liquid and paste mixers, powder and granular solid materials mixing machinery.

The gas and low viscosity liquid mixer features a simple structure and no rotating parts, low maintenance and repair, and low energy consumption. This type of mixing machine is divided into four types: airflow mixing, pipe mixing, jet mixing and forced circulation mixing.

Horizontal powder mixer for medium and high viscosity liquids and pastes generally have strong shearing action.

Thermoplastic material mixing machinery is mainly used for mixing thermoplastic materials (such as rubber and plastic) with additives; powdered and granular solid material mixing machines are mostly intermittent operations, and also include machines that combine mixing and grinding, such as rim machines.

Mixer Parts of Powder Mixer Machine

Mixer parts are mainly made of wear-resistant alloy materials, including high-speed mixing scraper, mixing fin, wear-resistant lining, mixing arm, mixing shovel, planetary shovel, mixing coulter, stirring rod, mixing raft, etc.

How Does Powder Mixer Machine Work?

The moving parts of the mechanical agitator also shear the liquid when it is rotated. The liquid is also subjected to shearing action when flowing through the wall and various fixing members installed in the container. These shearing effects will cause many Local eddy current diffusion.

For liquids of different density, composition, and immiscibility, the shearing action caused by the agitation and the strong turbulence shred the dense liquid into small droplets and uniformly disperse it into the main liquid.

Round concave mirrors are catoptric imaging. Mirrors( including convex) are reflecting back for imaging rather than get through the light, ray of light follows the law of reflection, that is what we called convergence. They always gather the light that shoot to the surface, ray of light that is entered parallelly will be focus on the spot again, ray of light is reflected from different angles because of different directions of surface normal. Round concave mirrors can not only focus parallel ray of light on the spot but also reflect parallel light from spot.

The diagram of a round concave mirror shows focus, focal length, centre of curvature and principal axis. Concave mirrors or gathering mirrors will deflect reflected ray of light. Concave mirrors will have different images because of the different distance between objects and mirrors, which is different from convex mirrors.

Round concave mirrors don’t have chromatic aberration because they are catoptric imaging, this advantage is can’t be compared with any lens. The resolution ratio is in direct proportion to the clear aperture of objective, it is difficult for the production of large aperture lens while concave mirrors that made according to reflection principal are easier. Therefore, round concave mirrors are always used for producing telescope.

The aspheric

When it comes to the lens, you have to mention the aspherical lens. In many people's understanding, the asperical lens is a symbol of high level, and the advanced lens is almost all aspherical lens.

Let's start with what is called a aspherical lens. The aspherical lens is contained in the camera lens, aspheric is often calculated according to the surface, some aspherical lens side, the other is not, or both sides is spherical, and so on.

In general, a lens with two or more aspherical lenses is a very advanced lens. So, is the aspheric surface a very difficult technique?

We can look at it from the other side.

Now, in terms of glasses, the aspheric surface is also very widely used, and in fact, it is no more expensive than the spherical lens. For numerical control grinders, the wave surface can also be made.

Clearly, many people's understanding of the aspheric surface is still stuck in the leica 501.2 myth, which itself has long since been broken.

Of course, many people would still use the so-called "grinding aspheric", but don't say what grind the aspheric surface. I believe that for many people, it's impossible to tell whether a picture is not a spherical lens.

Is the aspheric surface necessarily good?

Even if it's a cock shot, it's impossible for each lens to be aspherical, the aspheric lens is actually a supporting role in the lens, not the main character, the main corrective, the correction function, after the use of aspherical lenses, the image of the edge of the image will be solved well and the picture will be more average.

So, is it a good thing to have an aspheric surface? From the current situation, the use of aspheric surface technology has become the standard configuration, especially the high technology index lens, for example, large aperture wide-angle zoom lens, it is difficult to guarantee the quality of the picture without the aspheric surface.

But in terms of our film fans, the aspherical lens we can use is relatively limited, after all, we use the camera mainly concentrated in the last century 60-90s, until the 90s, aspherical lens or less. Here we're talking about 135, and less in 120. We have seen that CAI has built so many classic Hau shots, such as the 384.5 on SWC, and there is no aspherical lens.

In a series of SLR lenses designed by Mr. CAI for nikon, many of them have no aspheric surfaces. But it doesn't prevent these lenses from being a good shot, like chase 50, 1.4 SLR, and the picture is average.

留学生如何面对美国大学新冠肺炎

出门在外的留学生们在这个特殊的时期里，请一定要保护好自己，做好防护措施。留学生们应该注意个人清洁，勤洗手，尤其是在接触口鼻眼之前。出门最好佩戴口罩，减少前往人员密集的场所。如非必要尽量不出门，迫不得已出门的话， 尽量自行开车或者自行车，避免城做公交车、地铁诸如此类拥挤式的交通工具。外出归家应第一时间换下外套，清洁双手。

避免接触动物（包含野味）、禽鸟及其粪便，不去有活禽的市场和海鲜市场，注意食物安全和卫生，避免进食或者食用未熟透的动物产品，包括奶类、肉类和蛋类等等。在美国常常是食用牛扒、鸡扒等肉类，在这个关键时期，求真小编再次提醒同学们一定要将肉类烹饪至全熟再食用。

如果出现身体不适，特别是伴随感冒发烧或者咳嗽症状，一定要第一时间进行就医，切莫耽误治疗。在去往医院的途中，一定要切记全程佩戴口罩，做好防护。

留学生们除了要做好疫期防护外，学习这方面也不能耽误。越来越多的美国高校做出了疫情期间将线下课转换为线上课的措施以抗疫情，以避免师生聚集增加感染的机率。可能很多留学生无法适应线上课的模式，担心成绩跟不上，GPA下降，带来学业危机。不用担心，危机也可以是转机。求真教育的学术辅导团队老师们为留学生推出了专属一对一在线学术辅导课程，专业双语老师授课可以保证同学在家也能学得安心，兼顾防疫安全与在校GPA，不必担心学习落后跟不上，反之借此疫情机会弯道超车将成绩提升上去。同学们，快联系求真教育吧，第一时间为你匹配最优师资，疫情期间让你的学业稳步上升。

随着美国校园疫情肆虐，各个大学在预防疫情也是比之前有了更高等级的提升。部分留学生和家长也对美国大学疫情表示担忧。求真教育就来为大家梳理最新的美国大学各校的疫情应对措施，希望能帮助大家第一时间安排好自己的生活的学习，并对疫情做出有效的预防措施。

东西部著名大学均严阵以待

美国校园疫情下，美国大学采取的措施有所不同，但初衷都是希望学生少出门、少聚集、多待在家里或空气流通地方。加州大学伯克利分校宣布会对期中考试进行调整，包括时间和考试形式，部分教授宣布停课。洛杉矶分校则是为学生配备医护团队，建议有症状的学生不要到学校上课，目前也正在制定网课的安排。南加州大学则是建议取消三月到四月中旬的所有线下活动。华盛顿大学西雅图分校则宣布学生暂时需要先接受线上授课。

针对美国校园疫情，普林斯顿大学决定让学生从春假后到四月五日前在线上上课。范德堡大学已经取消所有线下课程，并且此政策会根据疫情发展进行调整，有可能延长至学期末。而纽约大学则宣布线上授课至少将持续到三月底。而斯坦福大学、哥伦比亚大学、普林斯顿大学为了学生的安全考虑，均已宣布停课。

独在异乡，留学生应该怎么办

很多留学生都反映，美国校园疫情严重的情况下，各学校应该像中国大学一样减少线下课程，改为更多地开发线上课程，让老师以直播的形式为学生答疑解惑。除此之外，网课系统也需要进一步完善，避免出现因为登陆人数过多，运行不稳定导致学生无法提交自己的作业和测验。在生活中，大家也要继续注重防护的三条原则：消灭传染源、切断传播途径以及保护好自身。

同学们要注意经常洗手，并且在接触口鼻时最好用上纸巾或者提前消毒。在外出时，要注意佩戴口罩，并且注意深色面朝外、金属条朝上的佩戴原则。如果出现发烧、干咳或者有接触过感染患者，要注意及时上报，尽早就业。当时，平时要注意饮食均衡和多运动，宅在家中也要保持良好的身材和作息规律。

疫情之下，学业会何去何从

随着美国确诊人数的不断上升，相信同学们需要在家适当安排好自己的学习。尤其对于本学期前几次小测成绩不理想的同学，可以趁此机会再重新巩固自身对之前知识点的理解。而对于在准备明年春秋季转学和研究生申请的同学们而言，大家可以加强自身标化考试成绩的安排，保持每天的背书和题目练习，以备更好地迎接疫情过后，接踵而至的各类标化考试。

另外，也可以趁这段时间初步规划好自身的兴趣、专业、学校定位等，并且完成文书的头脑风暴和初稿框架，更好地备战九月到来的申请季。当然，不管未来何去何从，大家千万不要轻信谣言，一定要注意接收来自学校官方的邮件。更不要造谣传谣，导致不必的恐慌。同学们更多是要把握好这段非常时期的停歇，更好地提高自己。

美国校园疫情目前仍属于初步阶段，美国大学采取防护措施更多是为了保障学生们的身体健康。同学们要认真服从学校的安排，合理安排学业，并且根据自身的实际，提升自己。相信春暖花开，疫情即将会消散，到时候同学们可以健健康康把学上，安安全全把家还。了解最新的美国新冠肺炎疫情信息，请关注求真教育美国新冠疫情信息专栏。
