第二部分 結構介紹及安裝
Part two. Structure instruction and installation
一、 結構及工作原理
I. Structure and working principle
㈠.結構（見下圖）
(i) Structure (see below picture)
PFRM型立式磨作為一種新型節能粉磨設備，其工作原理是：
As the new type energy saving grinding equipment, the working principle of PFRM vertical mill is as follows.
電動機驅動減速機帶動磨盤轉動，需粉磨的物料由鎖風喂料設備送入旋轉的磨盤中心，在離心力作用下，物料向磨盤周邊移動，進入粉磨輥道。在磨輥液壓力的作用下，物料受到擠壓、研磨和剪切作用而被粉碎。同時，熱風從圍繞磨盤的風環高速均勻向上噴出，粉磨后的物料被風環處的高速氣流吹起，一方面把粒度較粗的物料吹回磨盤重新粉磨，另一方面對懸浮物料進行烘干，細粉則由熱風帶入分離器進行分級，合格的細粉隨同氣流出磨，由收塵設備收集下來即為產品，不合格的粗粉在分離器葉片作用下重新落至磨盤，與新喂入的物料一起重新粉磨，如此循環，完成粉磨作業全過程。
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.主要部件的結構形式及技術特點
(ii) Structural type and technical feature of main part
1.傳動裝置 Driving device
立式磨的傳動裝置由主電機、聯軸器、減速機三部分組成，安裝在磨機下部，既要帶動磨盤傳動，還要承受磨盤、物料、磨輥的重量以及加壓裝置施加的碾磨壓力，是立式磨中最重要的部件之一。潤滑系統采用獨立的油站，并有油壓、油溫的自動保護系統，使全套裝置工作安全可靠。該型式的減速機具有體積小、重量輕、減速比大、傳動效率高等優點。關于主減速機的結構、工作原理等請詳細查閱《MLX200立式磨減速齒輪箱使用維護說明書》。
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.碾磨裝置 Grinding device
磨盤和磨輥是重要的研磨部件，它的形狀設計必須使被粉磨的物料在磨盤上形成厚度均勻穩定的料床，因此合理的磨盤形狀配以相適應的磨輥，對于穩定料層、提高粉磨效率、減少研磨消耗有著極為重要的作用。通過大量的調研和類比，我們采用盤形的磨盤形狀和輪胎形輥套，輥套為對稱結構，在磨損到一定程度后可翻面使用，延長其使用壽命。磨盤周邊有可以調節料層厚度的擋料圈。
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.加壓裝置 Pressure device
采用液壓自動或手動控制系統來施加及控制其對物料的作用力，可以根據物料易磨性的變化而自動地調整壓力，因而使磨機經常保持在最經濟條件下運行，這樣，既可以減少無用功的消耗，又能使輥套、襯板的壽命得到延長。同時，由于蓄能器的緩沖作用，使液壓缸施加壓力具有較大的彈性，又可自動調節，當遇到大而堅硬的雜物時，磨輥可以跳起，從而避免粉磨部件及傳動裝置因承受過大荷載而損壞。
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.限位裝置 Limit device
立式磨獨特的限位裝置可以使磨機輕載啟動，磨輥和磨盤之間的間隙可調，這樣既能保持穩定的料層厚度，提高粉磨效率，又能保證在斷料等不正常情況下磨輥和磨盤不直接接觸，避免磨機振動，對減速機起到保護作用。
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.分離裝置 Separating device
分離器設計為機械傳動、轉速可調的動態分離器，該分離器通過錐形轉子高速回轉，葉片與粗顆粒撞擊，給物料以較大的圓周速度，產生較大的離心力，使其進行分離，細顆粒可通過分離器葉片之間間隙出磨，由收塵器進行收集。該分離器分級效率高，調節余地大。
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.磨輥裝置 Grinding roller device
磨輥的裝置是采用一對調心滾子軸承，設計時對軸承作等壽命計算，軸承密封腔延伸到機殼外，不與含塵氣體接觸，所以只用簡單的填料密封就能保證磨輥軸承不進灰。磨輥設計為斜面安裝，楔形環壓緊，更換輥套十分方便。
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.磨機殼體及機架 Mill shell and frame
立式磨的殼體分為上殼體、下殼體和機架部分，每部分均采用螺栓連接，下殼體焊接在三個機架上。
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.

The connecting flange on lubrication pipeline and pipe connection on hydraulic pipeline should be sealed tightly without oil leakage. Use high pressure hose for the connecting part of hydraulic pipeline and main oil cylinder or inspection oil cylinder. The energy accumulator can be fixed on the mill lower frame near oil cylinder by support. Hydraulic pipeline should be fixed by pipe clamp at a distance of about 2m.
最后對設備基礎進行整體二次澆灌（下殼體的兩機架內部應予埋排水管）。
At last, make secondary grouting to the whole equipment foundation (pre-embed drainage pipe inside two frames of lower shell).
四.液壓及潤滑系統的酸洗
IV. Acid cleaning of hydraulic and lubrication system
液壓管道安裝分兩步進行，第一步為預安裝（配管），第二步為正式安裝。預安裝是為正式安裝作準備，是確保安裝質量的必要步驟。
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.
按液壓原理圖及管道安裝示意圖現場制作。
Fabricate on site according to hydraulic principle drawing and pipeline installation drawing.
㈠、預安裝（配管）
(i). Pre-installation (piping)
1.PFRM型系列立式磨的液壓管路系統一般采用無縫鋼管、高壓橡膠軟管等
The hydraulic pipeline system of PFRM vertical mill usually uses seamless steel tube and high pressure hose etc.
2.根據工藝設計和現場的具體情況，首先確定液壓站的位置。
As per process design and actual condition on site, firstly confirm the location of hydraulic station.
3. 配管，管接頭和主管焊接要平直，焊縫要均勻，不得有氣孔、裂紋等影響管路壓力泄漏的缺陷存在，條件允許的廠家應進行壓力試驗。
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.各管作記號卸下，準備進行清洗。
Mark each pipe and discharge for cleaning.
5.酸洗 Acid cleaning
一般按下列程序進行 Common process
脫脂→水沖洗→酸洗→中和→水沖洗→干燥空氣吹干→涂液壓油
Degrease-water washing-acid cleaning-neutralize-water washing-dry by dry air-coat hydraulic oi
具體步驟如下：Detailed steps are as follows.
(1)、用榔頭對油管逐點敲打，特別是對焊接處，以達到清除管道內的氧化皮和焊渣、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)、用濃度8～10％的氫氧化鈉溶液灌入油管內，浸泡3～4小時，然后用清水沖洗。
Pour sodium hydroxide solution with 8-10% concentration into oil pipe for 3-4 hours and then use water to wash.
(3)、用濃度15％的鹽酸溶液或磷酸溶液灌入油管內，浸泡6～8小時，然后倒出酸液，再向油管內灌入濃度10％蘇打溶液浸泡1小時后，用清水沖洗，壓縮空氣吹干，機油浸泡1小時。
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)、干燥空氣吹干。
Dry by dry air.
㈡.正式安裝
(ii) Formal installation
1. 酸洗后的管道按原作記號安裝回原處，并用相應的管卡固定。
Install the acid cleaned pipeline to the original place as per marks and fix it by corresponding pipe clamp.
2.連接高壓軟管、蓄能器。
Connect high pressure hose and energy accumulator.
