外文翻译 专 业 过程装备与控制工程 学 生 姓 名 杨 连 明 班 级 B 装备 031 学 号 0310140120 指 导 教 师 葛 友 华 nts 2 HOROMILL的性能评定 Gerard Marchal 杨 连 明译 (删节 ) 摘 要 ： FCB的粉碎顾问对使用 4年以后的 HOROMILL进行了一次使用状况的评定。 关键词： HOROMILL；评定 ；粉磨 1、概述 自从最初建立以来 4年中， FCB的粉碎顾问评估了 Horomill的成绩。 1998 年 3 月 1 日 上午 12 点 ,Gerard Marchal 顾问及其同伴对 Horomill 的使用性能进行了次评定。 自从 1993 年 VDZ 首次申请工业运用磨机的出现，世界各国的工厂都开始安装这样的组合。现在我们通过一系列的申请终于有机会来评估一下它的成绩。 料床挤压粉磨 这个原则经常被提出，所以这篇文章的目的不是提出机器的另一种描述，而只是最简要的大概叙述。 Horomill 是在基于 料床挤 压粉磨 的原则，其中一个筒体由倾斜的滑履支撑，并且以超临界转速旋转。在内壳里面，一个水利滚筒在磨床上面施加压由压辊向物料层施加压力，从而使材料与筒体以同样的速度旋转 ,并粘附在筒体上面。由刮料装置将物料刮下并进入导料装置，使这些材料贴在壳的表面进行碾压，同时调整壳内材料的运作。 材料在离开磨机之前已经被碾压过好几次 ,并经过 TVS 分离器的分离。 在 CEMENTI BUZZI和 ITALY的协助下 ， 90 年代早期产生的法国 FCB公司及其代表产品 HOROMILL， 2001年已经并逐渐发展成为拥有 15种成功运转的机型和 6个新的组件。按照料床挤压原理， HOROMILL能提供各种水泥生产企业的粉磨需求，比如入磨粒度，矿渣粉磨，并且比普通的球磨系统节能 35 80。另外， HOROMILL 的另一个显著优点是 结构紧凑 占地面积小 可操作性强 、 容易维护和保养。 表格 1 和 2 展现了目前正在使用 Horomill 的一些工厂以及一些典型的结果。我们可以非常清楚的看出与传统的解决方法相比，哪种消耗能量比较低。 对于 1 和 2两种型号的水泥，磨机消耗大约 14-19 千瓦 /小时 每吨。而工厂辅助用具的消耗普遍大约在 5-7 千瓦 /小时 每吨。 从第一个工厂的 试验结果， 得 出了一下几点： nts 3 1、对基于料床挤压粉磨的系统而言 ，纯石膏中水泥的需求必然等于或者高于普通的管状磨机（从 0%到 1%，更 甚至于到 3%，和开放电路的磨机相比 最多 3 ） 2、在参数相同式， 当考虑到搅拌机或者混凝土时，这些典型的磨机特征便对结果没有什么影响了，那些参数便和那些管状磨机的差不多了。 举例来说，从对某国将HOROMILL用于矿渣粉磨的统计数据来看， Horomill在无熟料磨机上面的运用展示出混凝土的需求量大约是 250KG每方米，在来自其它用管状磨机的工厂显示大约 200-210KG每 立方米。（平均 205立方米）。 3 、同样的， ，在 Horomill 里，带水泥的混凝土设置时间大约从最初的 320 最后设置的 450 分钟。球状磨机的价值大约在最初 300-320，最后 465 分钟。 上述使得 HOROMILL与传统的磨机有很大的区别， 这些都确认了 Horomill允许非外地的水泥的磨机通过和统的机器很相似。 很显然，水需求量的不同由于水泥的纯度。但是由于没有物理方面的相关，每个人除了欧洲大家都忽视了这一点。 2、 Horomill 粉磨系统 筒辊磨的工作原理与其他粉碎机械的工作原理不同，筒辊磨是应用料层 粉碎原理工作的，由进料装置、粉磨带和卸料装置二部分组成。它的新工艺巧妙地结合了球磨和辊压磨的基本思路，利用中等压力，使物料由一次喂入设备内而实现多次挤压粉磨。如图 1 所示，被磨物料由入料口下落在一水平回转的圆柱形筒体内，受离心力作用平布于由圆柱形筒体内表而构成的磨床的中端，随着筒体的回转运动进入磨床和其上方磨辊构成的挤压通道内，磨辊依靠液压系统向磨床上的被磨物料施加压力并借助挤压力引起的摩擦作用被动地回转运动，物料在挤压通道内完成一次粉磨作业后被提升并经由导料装置实现向磨机出口方向的运动，接受下一次挤压粉磨作 用。经过多 次挤压粉磨机后的物料离少下磨床，从出料口排出磨机。 筒辊磨粉磨系统一般可分为二种基本型式 :预粉磨型式、棍合粉磨型式、终粉磨型式。一般来说，前两种主要用于己有粉磨系统的技术改造，第二种主要用于新建粉nts 4 磨系统。在实践中，粉磨工艺系统的选择是多种多样的，主要取决于用户的要求，如预期的生产能力、原材料的类型、产品的特性、设备的能力和状况、投资预算、能耗费用等，以及筒辊磨在操作时对物料的要求，如物料粒度、粘性等，如图 6 所示的粉磨系统的应用目前还限于对粉体微观形貌要求小严的粉磨，如生料、煤、原矿。目前，根据实 践经验和具体条件，使得物料流向合理和设备配置合理，考虑到能耗费用等囚素，从而构成的筒辊磨备种粉磨工艺流程，可以大致归纳为从图 2 到图 6 的几种常见形式。 从图所示的粉磨工艺系统流程中可以看出，筒辊磨粉磨系统具有如下几方而特点 : (1)备种工艺流程形式上虽备小相同，但组成单元相同，筒辊磨是整个粉磨系统的关键组成部分。 (2)形式上的差异，主要是物料流向的差异。预粉磨型式是通过筒辊磨的物料全部进球磨机，棍合粉磨型式是从筒辊磨出来的产品和球磨机出料中的合格细粉由选粉机选出进入成品库，部分粗 料返回筒辊磨 :终粉磨型式是全部粗料返回筒辊磨，系统中无球磨机存在。 (3)备组成组元在现场都相隔一定的距离，要考虑用户要求确定具体粉磨系统工艺流程。 最后， Horomill 磨机的结果管状磨机相比是一样的。这些不同点是由第三代的分析家发现的，给了更多的 Rosin 倾斜。并开始被使用，导致了更多的水需求在纯水泥的要求上。第三代分析家的水泥很好，及时其体积和老一代工厂的水泥是不一样的。 在开始粉磨阶段，许多顾客都对此新机制持怀疑态度。因为许多人不懂这些湿料在没有空气去除机的情况下，是怎么被去除的。然而，意大 利人作了量的测试以及墨西哥人的工业测试显示出 Horomill 能够高效的烘干物料 ,并达到使其达到很高的湿度标准。并且相关原则也容许原材料的高效磨机。 Moctezuma Tepezingo 现在正在使用 Horomill 既做水泥也做原材料的磨，原材料的结果可以在表格中看见。在这些结果的基础上 ,以及 上面三个认证结果以及试运nts 5 转以后 ，另一个生产商 Galadari in Pakistan 也打算磨原材料和水泥。 申请在接踵迩而来随着 1993 年的展览，这个机器的第一个代理是 海德堡 的一个分公司，他为它的法国的一个公司 Faulquemont 订购。这个磨机现在 12 石膏在 布莱恩 。 磨机能在 5500 Blaine 下以 12 mtph 研磨硬石膏。且耗电量比以前降了三分之二。 经过深思熟虑过石膏之后， Maxit 又为 Krolpa (Thuringen)订购了一台 40-mtph的磨机。将会在 1998 年中旬正式运作。许多石膏供应商对 Horomill 表示了兴趣，目前已经有两个磨机被订购了，其中一台计划 1998 年年初开始使用。表格 5 中的曲线表示 Horomill 磨不同产品的结果，代替部分由 KW 来表示，用管状磨机的部分可以用Horomill 来代替。 下图 的曲线来自不同产品的 Horomill 研磨的结果。 结论 ： 1. 该项技术成熟可靠，设备运转平稳，振动噪音比较小，设备维护方便易于操作， Horomoll粉磨系统有较高自动化水平，设备起动程序简便。 2. 该磨机系统做为终粉磨系统主机设备少，工艺流程简单，布置方便。 3. 水泥粉磨电耗低， ，使得电的使用率非常高。 4. 使用 Horomoll 粉磨机以及管状机去磨个中水泥，工作显示正常。 5. 随着与法国 FCB公司技术合作的进一步深入 ,设备制造的国产化率可逐步扩大，该系统中 FCB公司外部配套设备如电机和润滑 系统 ，并且逐渐把国内的设备也用到那个体系中。 亦有逐步转化国产设备的可能。 nts 6 Milling:FCBs comminution adviser assesses the performance of the Horomill in the four years since the original installation Mar 1, 1998 12:00 PM Gerard Marchal Since the presentation at the 1993 VDZ Congress of the first industrial application of the mill, many units have been installed at plants around the world, and we now have the opportunity to assess its performance in a variety of applications. The principle has been presented so often that it is not the purpose of this article to put forward another description of the machine other than the briefest outline. Horomill is based on the particle bed compression principle of energy saving in which a shell, supported by slide shoes, rotates at a hypercritical speed. Inside the shell, a hydraulic roller exerts a pressure on the grinding bed, often causing material to become attached to the inner face of the shell by hypercritical shell speed. Scrapers are employed to remove this material, which then falls onto a diverting system, which pushes the material against the shell face for regrinding and adjusts the motion of this material inside the mill. The material is ground several times before leaving the mill and being classified by a high-efficiency TSV classifier. Tables 1 and 2 show which plants are currently operating the Horomill and the typical results. It is clear that the specific energy is low compared to conventional solutions, with the mill consumption for type 1 and type 2 cements being in the range 14 to19kWh per ton (at motor terminals), and the plant auxiliaries consumption generally being from 5 to 7kWh per ton. The results obtained on the first plants to be commissioned are plotted on Table 3, and give rise to the following points: nts 7 * For material bed grinding machines, the water demand of cement on pure paste is equal to or higher than the value found for ordinary tube mills (from 0% to 1%, more rarely to 3%, when compared to open circuit mills). * This typical mill feature has no influence on the results when considering mortar or concrete, where the parameters are similar to those of tube mills. For example, statistics from one of the countries where the Horomill is being used for clinker grinding show that water demand for concrete was about 205 kg per m3 when cement coming from other plants employing tube mills showed water demands of between 200 and 210 kg per m3. (Average 205 kg per m cubed). * Similarly, setting times for concrete made with cement ground in the Horomill were about 320 minutes for initial and 450 minutes for final setting. Values for ball mills ranged from 300 to 320 minutes for initial and 405 to 465 minutes for final. This confirms that the Horomill allows the milling of non-exotic cement in a similar manner to conventional machines. 2, the Horomill powder whet system The work principle that the tube Gun whet with other smash mechanical work principle a dissimilarity, the tube Gun whet is application anticipate a layer to smash a principle work of, from enter anticipate device, powder to whet to take and unload to anticipate to equip two part constitute.It of the new craft skillfully combined ball to whet with the Gun press grinding basic way of thinking and make use of medium etc. pressure, make material from feed equipments but realization at a time to for many times squeeze powder to whet.Such as figure 1 show, is whetted a material from go into anticipate a people whereabouts in a level the turn-over of the cylinder form tube body, be subjected to leave the mental exertion function even cloth in from the cylinder form tube form inside the body but composing of grinding machine of in carry, along with the turn round of tube body exercise into grinding machine with it above whet Gun to constitute of squeeze inside passage, whet Gun to depend on a liquid to press system toward grinding machine of is whetted a material to bring pressure and ask for help of to squeeze dint to cause of rub a function passively the turn-over exercise, material at squeeze inside passage complete a powder whet homework after drive promote combine through lead anticipate equip realization to whet machine export direction of exercise, accept next time squeeze powder whet a function.Squeeze powder through many times to whet machine behind of the material leave to descend the grinding machine less and anticipate to eject to whet machine from. Tube Guns whetting powder to whet system generally can is divided into two kinds of basic patterns: prepare powder to whet pattern, stick to match powder to whet pattern, eventually the powder whet pattern.Generally speaking, two nts 8 kinds of ex- technique reformations which mainly used for privately owned powder to whet system, the second mainly used for to lately set up powder to whet system.In the fulfillment, powder grinder the choice of the skill system be mainly varied, be decided by customers request, such as expectation of ability and condition of the characteristic, equipments of the type, product of production ability, original material, invest budget and can waste to use etc., and the tube Gun whet while operate to the request of material, such as material grain degree, glue sex etc., such as figure 6 show of the powder whet the application of system also is limited by to request small strict powder to whet to the powder body tiny view facial look so far, if living to anticipate, coal, original mineral.Currently, according to practice experience and concrete condition, make the material fly to reasonable and equipments to install reasonable, in consideration of can waste to use etc. jailbirds vegetable, thus constitute of the tube Gun whet to fully grow powder a grinder skill process, can mostly induce for from the figure 2 arrive figure 6 a few familiar forms. From the figure 2 go to figure 6 the powder show grinder skill system the process can see and the tube Gun whets powder to whet system to have as follows several squares but characteristics: (1)Fully grow craft process although the formality have small homology, constitute an unit homology, tube Guns whet is the key that the whole powder whets system to constitute part. (2)The difference of formality is the difference that the material fly to.Prepare powder to whet pattern is whet through a tube Gun of all of the material enter ball to whet machine, the stick matches powder to whet product and ball that pattern whets out from the tube Gun to whet a machine to anticipate medium qualified and thin powder from choose powder machine to nts 9 select into a finished product database, the part is thick anticipate to return to tube Gun to whet:eventually the powder whet pattern is all thick anticipate to return to tube Gun to whet, in the system have no ball to whet machine existence. (3)Fully constitute a set of dollar is on the spot and all separated certain distance, consider the customer requests to make sure that the concrete powder whets a system craft process. Obviously, a small difference in the water demand always exists on the basis of a pure cement probe, but as there is no physical action in relation to this test, everybody, with the exception of one European country, forgets it. Finally, the results from Horomill grinding compared to tube mills is equivalent to the difference found by users when third-generation classifiers, giving more Rosin rammler slope, began to be used causing more water demand on the pure cement probe. Third-generation classifier cement is good, even if the grain size is different from cement ground in an old grinding plant. Raw grinding Initially, many clients were sceptical about using the new system for raw meal grinding with many being unable to understand how the moisture could be removed from the material by a non-airswept mill. However, extensive tests conducted in Trino (Italy) and industrial tests in Tepetzingo (Mexico) have shown that the Horomill is able to efficiently dry materials with high moisture levels and that the principles involved allow efficient grinding of raw material. The Moctezuma Tepezingo plant is now using the Horomill for both cement and raw material grinding, and the results for raw material can be seen in Table 4. On the basis of these results, another manufacturer, Galadari in Pakistan, intends to use the Horomill for grinding both cement and raw materials, when commissioning occurs next year. Other applications Following the presentation at VDZ in 1993, the first client for the machine was a Heidelberg subsidiary, which ordered a Horomill for its SMA Faulquemont plant in France. The mill is currently grinding 12 mtph of anhydrite at 5500 Blaine. Power consumption is claimed to be three times lower than the vibratory mill used before. Again considering anhydrite, Maxit has ordered a 40-mtph mill for Krolpa (Thuringen), which should be in full operation in the middle part of 1998. nts 10 Many suppliers of ground calcium carbonate (GCC) also h
