第二部分 结构介绍及安装
Part two. Structure instruction and installation
一、 结构及工作原理
I. Structure and working principle
㈠.结构（见下图）
(i) Structure (see below picture)
PFRM型立式磨作为一种新型节能粉磨设备，其工作原理是：
As the new type energy saving grinding equipment, the working principle of PFRM vertical mill is as follows.
电动机驱动减速机带动磨盘转动，需粉磨的物料由锁风喂料设备送入旋转的磨盘中心，在离心力作用下，物料向磨盘周边移动，进入粉磨辊道。在磨辊液压力的作用下，物料受到挤压、研磨和剪切作用而被粉碎。同时，热风从围绕磨盘的风环高速均匀向上喷出，粉磨后的物料被风环处的高速气流吹起，一方面把粒度较粗的物料吹回磨盘重新粉磨，另一方面对悬浮物料进行烘干，细粉则由热风带入分离器进行分级，合格的细粉随同气流出磨，由收尘设备收集下来即为产品，不合格的粗粉在分离器叶片作用下重新落至磨盘，与新喂入的物料一起重新粉磨，如此循环，完成粉磨作业全过程。
The motor drives reducer to drive the mill disk rotate. The material to be ground is fed to the rotating mill disk center by air lock feeder. The material moves to the mill disk circum and enters into grinding roller way under the effect of centrifugal force. Meanwhile, the hot air upward sprays uniformly at high speed from the air ring around mill disk. The ground material is blown by high speed air flow at air ring. The coarse material is blown to mill disk for regrinding. The suspended material is dried and the fine powder is fed to separator for grading by hot air. The qualified fine powder discharged from mill along with air flow and collected by dust collector is the product. The unqualified coarse powder re-falls to the mill disk under the effect of separator blade and is reground with new fed material. This process cycles until the grinding work is completed.
㈡.主要部件的结构形式及技术特点
(ii) Structural type and technical feature of main part
1.传动装置 Driving device
立式磨的传动装置由主电机、联轴器、减速机三部分组成，安装在磨机下部，既要带动磨盘传动，还要承受磨盘、物料、磨辊的重量以及加压装置施加的碾磨压力，是立式磨中最重要的部件之一。润滑系统采用独立的油站，并有油压、油温的自动保护系统，使全套装置工作安全可靠。该型式的减速机具有体积小、重量轻、减速比大、传动效率高等优点。关于主减速机的结构、工作原理等请详细查阅《MLX200立式磨减速齿轮箱使用维护说明书》。
The drive device of vertical mill contains main motor, coupling and reducer. It is installed in the bottom of the mill. It need to not only drive the mill disk to drive, but also bear the weight of mill disk, material and mill roller as well as grinding pressure brought by pressure device. It is one of the most important parts of vertical mill. Lubrication system adopts independent oil station with oil pressure and temperature automatic protection system to make the whole device work safely and reliably. This type of reducer has small volume, light weight, large reduction ratio and high driving efficiency. The structure and working principle etc. please refer to
2.碾磨装置 Grinding device
磨盘和磨辊是重要的研磨部件，它的形状设计必须使被粉磨的物料在磨盘上形成厚度均匀稳定的料床，因此合理的磨盘形状配以相适应的磨辊，对于稳定料层、提高粉磨效率、减少研磨消耗有着极为重要的作用。通过大量的调研和类比，我们采用盘形的磨盘形状和轮胎形辊套，辊套为对称结构，在磨损到一定程度后可翻面使用，延长其使用寿命。磨盘周边有可以调节料层厚度的挡料圈。
Mill disk and mill roller are important grinding parts. The shape design of the grinding device must make the material form material bed with uniform and stable thickness on the mill disk, so reasonable mill disk shape matched with suitable mill roller has very important effect in steadying material layer, improving grinding efficiency and reducing grinding consumption. Through a mass of researching and analogy, we use disk type mill disk and tyre type roller shell. Roller shell is symmetrical structure. It can be turn-over used after a certain wear to extend its service lift. The retention rings are located around the mill disk to adjust the thickness of material layer.
3.加压装置 Pressure device
采用液压自动或手动控制系统来施加及控制其对物料的作用力，可以根据物料易磨性的变化而自动地调整压力，因而使磨机经常保持在最经济条件下运行，这样，既可以减少无用功的消耗，又能使辊套、衬板的寿命得到延长。同时，由于蓄能器的缓冲作用，使液压缸施加压力具有较大的弹性，又可自动调节，当遇到大而坚硬的杂物时，磨辊可以跳起，从而避免粉磨部件及传动装置因承受过大荷载而损坏。
Pressure device adopts automatic or manual control system to impose and control its force to material. It can automatically adjust pressure according to the change of material grindability thus the mill always runs under the most economic conditions to reduce idle work consumption and extend the service life of roller shell and lining plate. Meanwhile, the buffer action of energy accumulator makes the hydraulic cylinder have large elasticity imposing pressure and adjust automatically. When meet large and hard sundries, the mill roller can jump to avoid damage caused by grinding part and driving device undertaking over load.
4.限位装置 Limit device
立式磨独特的限位装置可以使磨机轻载启动，磨辊和磨盘之间的间隙可调，这样既能保持稳定的料层厚度，提高粉磨效率，又能保证在断料等不正常情况下磨辊和磨盘不直接接触，避免磨机振动，对减速机起到保护作用。
The unique limit device of vertical mill can make the mill start under load. The gap between mill roller and mill disk can be adjusted. It can keep stable thickness of material layer, improve grinding efficiency, and ensure the mill roller and mill disk not contact directly under unnormal conditions such as material interrupt to avoid mill vibration thus protect reducer.
5.分离装置 Separating device
分离器设计为机械传动、转速可调的动态分离器，该分离器通过锥形转子高速回转，叶片与粗颗粒撞击，给物料以较大的圆周速度，产生较大的离心力，使其进行分离，细颗粒可通过分离器叶片之间间隙出磨，由收尘器进行收集。该分离器分级效率高，调节余地大。
The separator is a dynamic separator with mechanical drive and adjustable rotating speed. The cone rotor rotates in high speed and the blade impacts coarse particle to provide large circular velocity to the material and generate large centrifugal force to separate the material. The fine particle can be discharged from mill through the gap between separator blades and collected by dust collector. This separator has high grading efficiency and large adjusting scope.
6.磨辊装置 Grinding roller device
磨辊的装置是采用一对调心滚子轴承，设计时对轴承作等寿命计算，轴承密封腔延伸到机壳外，不与含尘气体接触，所以只用简单的填料密封就能保证磨辊轴承不进灰。磨辊设计为斜面安装，楔形环压紧，更换辊套十分方便。
Grinding roller device adopts a pair of self-aligning roller bearings. During design, make equal lift calculating for bearing. The seal chamber of bearing extends to the outside of mill shell. It doesn’t contact dust air so simple packing seal can ensure no dust enter into grinding roller bearing. Grinding roller is designed as slope installation and impacted by wedge shape ring to make the roller shell change easily.
7.磨机壳体及机架 Mill shell and frame
立式磨的壳体分为上壳体、下壳体和机架部分，每部分均采用螺栓连接，下壳体焊接在三个机架上。
Vertical mill’s shell divides into upper shell, lower shell and frame. Each part is connected by bolt. The lower shell is welded on three frames.

液压管道安装分两步进行，第一步为预安装（配管），第二步为正式安装。预安装是为正式安装作准备，是确保安装质量的必要步骤。
The first step of hydraulic pipeline installation is pre-installation (piping) and the second step is formal installation. Pre-installation is to make preparation of formal installation. It is a necessary step to ensure installation quality.
按液压原理图及管道安装示意图现场制作。
Fabricate on site according to hydraulic principle drawing and pipeline installation drawing.
㈠、预安装（配管）
(i). Pre-installation (piping)
1.PFRM型系列立式磨的液压管路系统一般采用无缝钢管、高压橡胶软管等
The hydraulic pipeline system of PFRM vertical mill usually uses seamless steel tube and high pressure hose etc.
2.根据工艺设计和现场的具体情况，首先确定液压站的位置。
As per process design and actual condition on site, firstly confirm the location of hydraulic station.
3. 配管，管接头和主管焊接要平直，焊缝要均匀，不得有气孔、裂纹等影响管路压力泄漏的缺陷存在，条件允许的厂家应进行压力试验。
The welding of piping, pipe connection and main pipe should be straight. The welding line should be uniform without defect such as air hole or crack which may cause pipeline pressure leakage. The manufacturer should take pressure test if he has such ability.
4.各管作记号卸下，准备进行清洗。
Mark each pipe and discharge for cleaning.
5.酸洗 Acid cleaning
一般按下列程序进行 Common process
脱脂→水冲洗→酸洗→中和→水冲洗→干燥空气吹干→涂液压油
Degrease-water washing-acid cleaning-neutralize-water washing-dry by dry air-coat hydraulic oi
具体步骤如下：Detailed steps are as follows.
(1)、用榔头对油管逐点敲打，特别是对焊接处，以达到清除管道内的氧化皮和焊渣、毛刺。
Beat the oil pipe point to point especially to the welded part by hammer to clean up oxide skin inside pipeline as well as welding slag and burr.
(2)、用浓度8～10％的氢氧化钠溶液灌入油管内，浸泡3～4小时，然后用清水冲洗。
Pour sodium hydroxide solution with 8-10% concentration into oil pipe for 3-4 hours and then use water to wash.
(3)、用浓度15％的盐酸溶液或磷酸溶液灌入油管内，浸泡6～8小时，然后倒出酸液，再向油管内灌入浓度10％苏打溶液浸泡1小时后，用清水冲洗，压缩空气吹干，机油浸泡1小时。
Pour hydrochloric acid or phosphoric acid solution with 15% concentration into oil pipe for 6-8 hours. Then pour out acid solution and pour soda solution with 10% concentration into oil pipe for 1 hour. After that, use water to wash and dry by compressed air and then pour into machine oil for 1 hour.
(4)、干燥空气吹干。
Dry by dry air.
㈡.正式安装
(ii) Formal installation
1. 酸洗后的管道按原作记号安装回原处，并用相应的管卡固定。
Install the acid cleaned pipeline to the original place as per marks and fix it by corresponding pipe clamp.
2.连接高压软管、蓄能器。
Connect high pressure hose and energy accumulator.
