附录A Cone Crushers

Cone Crusher is suitable to crush various kinds of ores and rocks of medium or above medium https://www.360docs.net/doc/5610548265.html,pared with Jaw Crusher, Spring Cone Crusher is of stable structure, high efficiency, easy adjustment,and economical using etc. The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the Cone Crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance. This type of crushing chamber depends upon the size offeeding and fineness of the crushed product. The standard type (PYB) is applied to medium crushing, themedium type is applied to medium or fine crushing and the short head type is applied to fine crushing.

Working Principle of Spring Cone Crusher:

Spring Cone Crusher crushes materials by the working surface between the movable cone and fixed cone.So it is more advanced and efficiency than Jaw Crusher. The movable cone is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and thwheelof the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in theeccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grindedmaterials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole; consequently the output Intense competition and strong fluctuations in the price of raw materials entail a constant endeavor by the mining industry to identify more energy and cost-efficient solutions. Sandvik Mining and Construction is participating in this development to meet the demands of customers. A number of new products were launched in 2009, including an innovative solution for cone crushers. The Sandvik Flexifeed is a new type of mantle with a unique,

patented design and functionality that boosts productivity and raises the quality of crush material. The mantle offers better utilization of the crushing chamber and more uniform wear

of the entire chamber, extending the service life by between 20 and 50%, depending on the application.

Sandvik cone crushers are of advanced design with a small footprint and high capacity in relation to size. They have high reduction efficiency and give very good product shape. With hydraulically adjusted CSS, the option of automation, a choice of several different crushing chambers, and many other high-performance features, each model is versatile, user-friendly and highly productive. The Sandvik CS- and CH-series of cone crushers have a wide field of use as they can easily be matched to changes in production through the proper selection of crushing chamber and eccentric throw. Our cone crushers are ideal for secondary and tertiary crushing and the compact and easy-to-service design makes them a perfect choice for mobile

installations. Our crushers provide automatic overload protection and can be equipped with our automatic setting system ASRi. This system optimizes cone crusher efficiency and automatically adapts the crusher to variations in feed conditions. By continuously measuring and compensating for crusher liner wear, ASRi allows you fully utilize crusher liners and schedule liner replacements to coincide with planned maintenance stops. ASRi also assists in keeping your crusher choke fed. This maximizes rock-on-rock crushing, which helps to optimize the quality of your final product.

High Performance Lowest Total Cost

The hydraulically adjusted CS & CH cone crushers manufactured by Sandvik are characterized by robust design and high performance. In combination with the CLP crushing chambers, high motor powers give these crushers capacities which are in most cases comparable with those of other, larger crushers. The CLP advantages are: –Constant feed acceptance capability –Increased output –High-quality products –Increased liner life –Lowest total cost Sandvik cone crushers can be equipped with an automatic setting system, ASRi, which can improve performance even more and also provides integration with sophisticated plant control systems.

CLP crushing chamber. CLP stands for Constant Liner Performance. The almost vertical profile of the feed opening area means that the shape of the chamber remains virtually unchanged throughout the wearing lifeExcellent Versatility

Our cone crushers have a wide field of use. Several standard crushing chambers are available for each model. The crushers can easily be matched to changes in production through the proper selection of crushing chamber and eccentric throw. Sandvik cone crushers are an excellent choice as secondary crushers in combination with a jaw or a primary gyratory crusher or in the third or fourth crushing stage. Thanks to their built-in versatility, these crushers will enable you to cope with most production requirements in a changing future.

Several standard crushing chambers are available. The crushers can easily be matched to changes in production by the proper selection of crushing chamber and eccentric throw.

Full Control of the Process

The Hydroset system provides safety and setting adjustment functions, and incorporates a heavy-duty hydraulic cylinder which supports the mainshaft and adjusts its position. The Hydroset system provides automatic overload protection to permit the passage of tramp iron or other uncrushable material. The system then automatically returns the mainshaft smoothly to its original position. When the cone crusher is equipped with our automatic setting system, ASRi, the actual crushing load inside the crusher is continuously monitored. This makes it possible to optimize crusher utlilization allowing you to squeeze the ultimate performance from your machine at all times.

The crushers can be equipped with ASRi, which monitors the load on the crusher. This gives considerably improved results and optimum crusher utilization.

Easy to Handle and Maintain

Much attention has been paid to making our crushers as easy to operate and maintain as possible. All service and inspection is carried out from above, which makes the work easier and the maintenance costs lower. Robust sealing to the inner crusher mechanics provides more effective protection against dust and other unwanted particles – reducing maintenance

and increasing the life of the crusher. The automatic setting regulation system ASRi, not only optimizes production, it also keeps track of liner wear. This makes it easy to plan liner changes and minimize interruptions in production. In addition to the high capacity, Sandvik CS & CH crushers are compact, which makes them very easy to move and to install.

Largest Sandvik cone crushers to be installed at Namibian uranium mine ix of the largest Sandvik cone crushers –CH880s – are to be installed at the greenfield Trekkopje uranium mine project in Namibia. The order follows the ground-breaking delivery of six similar

crushers to the Tati Nickel Mine in Botswana in 2007, according to Gavin Harries, Regional Sales Manager for Africa at Sandvik Mining and Construction.

The more than USD700 M Namibian project – owned by the global French energy group Areva – is a very large, low-grade, shallow uranium source that consists of two deposits; the Trekkopje deposit and the Klein Trekkopje deposit, located approximately seven kilometers apart. The mine is expected to become one of the world’s ten largest ura nium mines when it is fully commissioned and it will also be one of the top five low-cost open-pit uranium operations in the world.

The mining tenement covers an area of over 30,000 hectares, with the Rossing Uranium mine situated 35 kilometers south of the property and the newly developed Langer Heinrich uranium mine located 81 kilometers to the southeast.

The six Sandvik crushers, which will be used to process 100,000 tonnes of ore a day from an open-pit operation situated in an arid desert region about 65 kilometers inland from the coastal town of Swakopmund, will be manufactured at a Sandvik plant in Sweden and delivered to the mine via the Namibian port of Walvis Bay. Installation is scheduled for October this year (2010).

The Trekkopje mine, which began producing uranium oxide in small quantities last year, is scheduled to reach full production by 2012. Mining activities include topsoil and overburden removal, drilling, blasting, loading, and feeding of ore to the plant for treatment. Ore removed from the pit will be transported to a moveable primary crusher located nearby, and then taken by conveyors to two Sandvik CH880 crushers for secondary crushing and to four CH880 crushers for tertiary crushing, to produce a final product size of -38 millimeters before the material is delivered to the agglomerators and heap leach pad.

According to Gavin Harries,the vast experience of Sandvik as a mining equipment supplier world-wide and the proven high productivity and reliability of the CH880 crushers were the main reasons that Sandvik won the order.

“This is the first Sandvik order placed by Areva Mining in Africa and we are pleased to be one of the suppliers to the Trekkopje mine. Since Areva Mining is one of the biggest global companies in the field, this will be a reference of great importance for Sandvik as a mining

Inventory management Inventory Control On the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion. The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility. Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored: First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments . Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get. Even as SAP, BAAN ERP world, the field of

机械设计 摘要:机器是由机械装置和其它组件组成的。它是一种用来转换或传递能量的装置,例如:发动机、涡轮机、车辆、起重机、印刷机、洗衣机、照相机和摄影机等。许多原则和设计方法不但适用于机器的设计,也适用于非机器的设计。术语中的“机械装置设计”的含义要比“机械设计”的含义更为广泛一些,机械装置设计包括机械设计。在分析运动及设计结构时,要把产品外型以及以后的保养也要考虑在机械设计中。在机械工程领域中,以及其它工程领域中,所有这些都需要机械设备,比如:开关、凸轮、阀门、船舶以及搅拌机等。 关键词:设计流程设计规则机械设计 设计流程 设计开始之前就要想到机器的实际性,现存的机器需要在耐用性、效率、重量、速度,或者成本上得到改善。新的机器必需具有以前机器所能执行的功能。 在设计的初始阶段,应该允许设计人员充分发挥创造性,不要受到任何约束。即使产生了许多不切实际的想法,也会在设计的早期,即在绘制图纸之前被改正掉。只有这样,才不致于阻断创新的思路。通常,还要提出几套设计方案,然后加以比较。很有可能在这个计划最后决定中,使用了某些不在计划之内的一些设想。 一般的当外型特点和组件部分的尺寸特点分析得透彻时,就可以全面的设计和分析。接着还要客观的分析机器性能的优越性,以及它的安全、重量、耐用性,并且竞争力的成本也要考虑在分析结果之内。每一个至关重要的部分要优化它的比例和尺寸,同时也要保持与其它组成部分相协调。 也要选择原材料和处理原材料的方法。通过力学原理来分析和实现这些重要的特性,如那些静态反应的能量和摩擦力的最佳利用,像动力惯性、加速动力和能量;包括弹性材料的强度、应力和刚度等材料的物理特性,以及流体润滑和驱动器的流体力学。设计的过程是重复和合作的过程,无论是正式或非正式的进行,对设计者来说每个阶段都很重要。 最后,以图样为设计的标准,并建立将来的模型。如果它的测试是符合事先要

Statistical hypothesis testing Adriana Albu,Loredana Ungureanu Politehnica University Timisoara,adrianaa@aut.utt.ro Politehnica University Timisoara,loredanau@aut.utt.ro Abstract In this article,we present a Bayesian statistical hypothesis testing inspection, testing theory and the process Mentioned hypothesis testing in the real world and the importance of, and successful test of the Notes. Key words Bayesian hypothesis testing; Bayesian inference;Test of significance Introduction A statistical hypothesis test is a method of making decisions using data, whether from a controlled experiment or an observational study (not controlled). In statistics, a result is called statistically significant if it is unlikely to have occurred by chance alone, according to a pre-determined threshold probability, the significance level. The phrase "test of significance" was coined by Ronald Fisher: "Critical tests of this kind may be called tests of significance, and when such tests are available we may discover whether a second sample is or is not significantly different from the first."[1] Hypothesis testing is sometimes called confirmatory data analysis, in contrast to exploratory data analysis. In frequency probability,these decisions are almost always made using null-hypothesis tests. These are tests that answer the question Assuming that the null hypothesis is true, what is the probability of observing a value for the test statistic that is at [] least as extreme as the value that was actually observed?) 2 More formally, they represent answers to the question, posed before undertaking an experiment,of what outcomes of the experiment would lead to rejection of the null hypothesis for a pre-specified probability of an incorrect rejection. One use of hypothesis testing is deciding whether experimental results contain enough information to cast doubt on conventional wisdom. Statistical hypothesis testing is a key technique of frequentist statistical inference. The Bayesian approach to hypothesis testing is to base rejection of the hypothesis on the posterior probability.[3][4]Other approaches to reaching a decision based on data are available via decision theory and optimal decisions. The critical region of a hypothesis test is the set of all outcomes which cause the null hypothesis to be rejected in favor of the alternative hypothesis. The critical region is usually denoted by the letter C. One-sample tests are appropriate when a sample is being compared to the population from a hypothesis. The population characteristics are known from theory or are calculated from the population.

农村社会养老保险的现状、问题与对策研究社会保障对国家安定和经济发展具有重要作用,“城乡二元经济”现象日益凸现,农村社会保障问题客观上成为社会保障体系中极为重要的部分。建立和完善农村社会保障制度关系到农村乃至整个社会的经济发展,并且对我国和谐社会的构建至关重要。我国农村社会保障制度尚不完善,因此有必要加强对农村独立社会保障制度的构建,尤其对农村养老制度的改革,建立健全我国社会保障体系。从户籍制度上看,我国居民养老问题可分为城市居民养老和农村居民养老两部分。对于城市居民我国政府已有比较充足的政策与资金投人,使他们在物质和精神方面都能得到较好地照顾,基本实现了社会化养老。而农村居民的养老问题却日益突出,成为摆在我国政府面前的一个紧迫而又棘手的问题。 一、我国农村社会养老保险的现状 关于农村养老,许多地区还没有建立农村社会养老体系,已建立的地区也存在很多缺陷,运行中出现了很多问题,所以完善农村社会养老保险体系的必要性与紧迫性日益体现出来。 (一)人口老龄化加快 随着城市化步伐的加快和农村劳动力的输出,越来越多的农村青壮年人口进入城市,年龄结构出现“两头大,中间小”的局面。中国农村进入老龄社会的步伐日渐加快。第五次人口普查显示:中国65岁以上的人中农村为5938万,占老龄总人口的67.4%.在这种严峻的现实面前,农村社会养老保险的徘徊显得极其不协调。 (二)农村社会养老保险覆盖面太小 中国拥有世界上数量最多的老年人口,且大多在农村。据统计,未纳入社会保障的农村人口还很多,截止2000年底,全国7400多万农村居民参加了保险,占全部农村居民的11.18%,占成年农村居民的11.59%.另外,据国家统计局统计,我国进城务工者已从改革开放之初的不到200万人增加到2003年的1.14亿人。而基本方案中没有体现出对留在农村的农民和进城务工的农民给予区别对待。进城务工的农民既没被纳入到农村养老保险体系中,也没被纳入到城市养老保险体系中,处于法律保护的空白地带。所以很有必要考虑这个特殊群体的养老保险问题。

机械外文文献翻译 Overall position of Agricultural Mechanization in Turkey Agricultural equipment and machinery are the indispensable part of agricultural activities. If these instruments, which are used in various stages of production, are not used properly, there may be some problems. So, how can we use them properly ? As the proverb goes, “It is the want of care that makes the field bare”. They return the money and efforts invested in them if they are maintained well. Ploughs, which were being used in our country up until recently, resemble those ploughs of the various tribes that lived in Anatolia long time ago. It is because one society gets use of societies that lived before. Some of the black ploughs that were being used up until recently resemble the ploughs that had been used in the ancient Rome. The first agricultural school was established in the Ottoman Empire in 1846. The first domestic heavy ploughs was manufactured i n Izmir 90 years ago, and tractor was introduced 80 years ago. However, it was only the foundation of the Republic that the tractor began to be used in agricultural activities. Agricultural mobilization began with modern agricultural practices in the Atatürk Forest Farm, which was founded by the Great Atatürk. Use of modern agricultura l equipment was encouraged,

大学毕业论文---软件专业外文文献中英文翻译

软件专业毕业论文外文文献中英文翻译 Object landscapes and lifetimes Tech nically, OOP is just about abstract data typing, in herita nee, and polymorphism, but other issues can be at least as importa nt. The rema in der of this sect ion will cover these issues. One of the most importa nt factors is the way objects are created and destroyed. Where is the data for an object and how is the lifetime of the object con trolled? There are differe nt philosophies at work here. C++ takes the approach that con trol of efficie ncy is the most importa nt issue, so it gives the programmer a choice. For maximum run-time speed, the storage and lifetime can be determined while the program is being written, by placing the objects on the stack (these are sometimes called automatic or scoped variables) or in the static storage area. This places a priority on the speed of storage allocatio n and release, and con trol of these can be very valuable in some situati ons. However, you sacrifice flexibility because you must know the exact qua ntity, lifetime, and type of objects while you're writing the program. If you are trying to solve a more general problem such as computer-aided desig n, warehouse man ageme nt, or air-traffic con trol, this is too restrictive. The sec ond approach is to create objects dyn amically in a pool of memory called the heap. In this approach, you don't know un til run-time how many objects you n eed, what their lifetime is, or what their exact type is. Those are determined at the spur of the moment while the program is runnin g. If you n eed a new object, you simply make it on the heap at the point that you n eed it. Because the storage is man aged dyn amically, at run-time, the amount of time required to allocate storage on the heap is sig ni fica ntly Ion ger tha n the time to create storage on the stack. (Creat ing storage on the stack is ofte n a si ngle assembly in structio n to move the stack poin ter dow n, and ano ther to move it back up.) The dyn amic approach makes the gen erally logical assumpti on that objects tend to be complicated, so the extra overhead of finding storage and releas ing that storage will not have an importa nt impact on the creati on of an object .In additi on, the greater flexibility is esse ntial to solve the gen eral program ming problem. Java uses the sec ond approach, exclusive". Every time you want to create an object, you use the new keyword to build a dyn amic in sta nee of that object. There's ano ther issue, however, and that's the lifetime of an object. With Ian guages that allow objects to be created on the stack, the compiler determines how long the object lasts and can automatically destroy it. However, if you create it on the heap the compiler has no kno wledge of its lifetime. In a Ianguage like C++, you must determine programmatically when to destroy the

Manufacturing Engineering and Technology(机械类英文文献+翻译)

Manufacturing Engineering and Technology—Machining Serope kalpakjian;Steven R.Schmid 机械工业出版社2004年3月第1版 20.9 MACHINABILITY The machinability of a material usually defined in terms of four factors: 1、Surface finish and integrity of the machined part; 2、Tool life obtained; 3、Force and power requirements; 4、Chip control. Thus, good machinability good surface finish and integrity, long tool life, and low force And power requirements. As for chip control, long and thin (stringy) cured chips, if not broken up, can severely interfere with the cutting operation by becoming entangled in the cutting zone. Because of the complex nature of cutting operations, it is difficult to establish relationships that quantitatively define the machinability of a material. In manufacturing plants, tool life and surface roughness are generally considered to be the most important factors in machinability. Although not used much any more, approximate machinability ratings are available in the example below. 20.9.1 Machinability Of Steels Because steels are among the most important engineering materials (as noted in Chapter 5), their machinability has been studied extensively. The machinability of steels has been mainly improved by adding lead and sulfur to obtain so-called free-machining steels. Resulfurized and Rephosphorized steels. Sulfur in steels forms manganese sulfide inclusions (second-phase particles), which act as stress raisers in the primary shear zone. As a result, the chips produced break up easily and are small; this improves machinability. The size, shape, distribution, and concentration of these inclusions significantly influence machinability. Elements such as tellurium and selenium, which are both chemically similar to sulfur, act as inclusion modifiers in

译文: 中国上市公司偏好股权融资:非制度性因素 国际商业管理杂志 2009.10 摘要:本文把重点集中于中国上市公司的融资活动,运用西方融资理论,从非制度性因素方面,如融资成本、企业资产类型和质量、盈利能力、行业因素、股权结构因素、财务管理水平和社会文化,分析了中国上市公司倾向于股权融资的原因,并得出结论,股权融资偏好是上市公司根据中国融资环境的一种合理的选择。最后,针对公司的股权融资偏好提出了一些简明的建议。 关键词:股权融资,非制度性因素,融资成本 一、前言 中国上市公司偏好于股权融资,根据中国证券报的数据显示,1997年上市公司在资本市场的融资金额为95.87亿美元,其中股票融资的比例是72.5%,,在1998年和1999年比例分别为72.6%和72.3%,另一方面,债券融资的比例分别是17.8%,24.9%和25.1%。在这三年,股票融资的比例,在比中国发达的资本市场中却在下跌。以美国为例,当美国企业需要的资金在资本市场上,于股权融资相比他们宁愿选择债券融资。统计数据显示,从1970年到1985年,美日企业债券融资占了境外融资的91.7%,比股权融资高很多。阎达五等发现,大约中国3/4的上市公司偏好于股权融资。许多研究的学者认为,上市公司按以下顺序进行外部融资:第一个是股票基金,第二个是可转换债券,三是短期债务,最后一个是长期负债。许多研究人员通常分析我国上市公司偏好股权是由于我们国家的经济改革所带来的制度性因素。他们认为,上市公司的融资活动违背了西方古典融资理论只是因为那些制度性原因。例如,优序融资理论认为,当企业需要资金时,他们首先应该转向内部资金(折旧和留存收益),然后再进行债权融资,最后的选择是股票融资。在这篇文章中,笔者认为,这是因为具体的金融环境激活了企业的这种偏好,并结合了非制度性因素和西方金融理论,尝试解释股权融资偏好的原因。

Advantages of Managed Code Microsoft intermediate language shares with Java byte code the idea that it is a low-level language witha simple syntax , which can be very quickly translated intonative machine code. Having this well-defined universal syntax for code has significant advantages. Platform independence First, it means that the same file containing byte code instructions can be placed on any platform; atruntime the final stage of compilation can then be easily accomplished so that the code will run on thatparticular platform. In other words, by compiling to IL we obtain platform independence for .NET, inmuch the same way as compiling to Java byte code gives Java platform independence. Performance improvement IL is actually a bit more ambitious than Java bytecode. IL is always Just-In-Time compiled (known as JIT), whereas Java byte code was ofteninterpreted. One of the disadvantages of Java was that, on execution, the process of translating from Javabyte code to native executable resulted in a loss of performance. Instead of compiling the entire application in one go (which could lead to a slow start-up time), the JITcompiler simply compiles each portion of code as it is called (just-in-time). When code has been compiled.once, the resultant native executable is stored until the application exits, so that it does not need to berecompiled the next time that portion of code is run. Microsoft argues that this process is more efficientthan compiling the entire application code at the start, because of the likelihood that large portions of anyapplication code will not actually be executed in any given run. Using the JIT compiler, such code willnever be compiled.
