Equipment weight isnt include the motor and reducer.I. PRINCIPLE OF OPERATION AND USES OF MILLTube mill is a hori

4、zontal rotary cylinder, load in abrasive mediums (general they are steel grinding balls, clypeus). To crush the materials mainly by percussion energy of the abrasive bodies when the shell rotary to lift and fall them, and the materials to be crushed. During the operational progress, by roll and slid

5、e repeatedly, the materials were got slide grinding and percussive crushing. So massive material become powder.This machine is mainly used in grinding for cement raw meals and cement clinkers.II. SUMMARY FOR STRUCTURE(I)Transmission systemTransmission system is comprised of motor, reduction unit, tr

6、ansmission shaft, girth gear and pinion (central drive mill dont use girth gear and pinion), coupling etc. The reduction unit is connected to the motor by spring coupling, and the pinion is connected to the reduction unit by spring coupling which has a good damping capacity and may reduce the shock

7、and vibration influence of mill shell on the reduction unit and increase the service lift of the equipment and convenient to main tain, Girth gear is fixed on the flange of shell body, shell body is rotated by motor passing reducer transmission shaft pinion and girth gear rim. In order to increase s

8、ervice lift of transmission gears, the mill uses the “large modified” gear.(II)Feed deviceFeed device mainly consists of charging hopper, supports, observation door, etc. Liner is fixed in the charging hopper. But it also uses materials as liner to reduce its wearing for charging hopper. The spacers

9、 are used between the hopper and the support to adjust the central height of the hopper by increasing or decreasing the spacer pieces.(III)Rotating partRotating part has charging and discharging screw, charging and discharging Trunnion shafts, girth gear(central drive hasnt girth gear) shell body, l

10、iners and compartment separators, etc.Shell body is made of steel plates, which are rolled up and welded. The plain-end covers of the same kind of steel plates are welded on the shell body ends. There are manholes on shell body with each one has a strengthen edge. The mill has a coarse grinding comp

11、artment and a fine grinding compartment. The circular liners of ZGMn13 manganese casting steel are bolted on the shell body in the coarse grinding compartment. The shape of bolts hole is oval to prevent the stress concentration. Liners are used in the fine grinding compartment by bolt. The compartme

12、nt separators of ZGMn13 manganese casting steel are single layer. The two main bearings support the whole rotating part by two quill shafts. Quill shafts are connected with plain-end covers by bolts.()Main bearingMain bearings are comprised of globe bearings, bearing seats and upper covers, etc. The

13、 globes bearings are used for purposes of automatic alignment shaft lines of trunnion shaft each other, and make regular oil lubrication for main bearings.The fixed oil rings (belt oil rings) are installed on the trunnion shafts for lubrication, to prevent oil leakage. Small oil brushes are installe

14、d on the both sides of main bearing and oil scrapers are installed on the side of near shell body. (Thin oil station is used according to customs requirement).Because the grinding produces a large amount of heat, the main bearings are cooled by water to keep the normal operation of the main bearings

15、. Heat-insulating material is filled into the gap between the screw tube and trunnion shaft to prevent heat transfer.Discharging device consists of discharging cover, supports, discharging screen, etc. The discharging screen is connected with discharging screw tube by bolts. The ground material drop

16、s into discharging cover through the screen. Some objects (such as iron pieces, bolts, etc.) will be removed from exit. The pipeline connected with dust collector is installed on the discharging cover. Air lock device is installed on the lower part of discharging cover which is connected with convey

17、ing equipment in order to avoid air leak.III. INSTALLATION(I) Foundation1.1 Foundation check and accept(1) Before installing the mill, the foundation should be cleared up and checked over for quality, its strength should conform to requirements of relevant communications.(2) Arrangement and dimensio

18、n of eyelet bolt holes of foundation should be appropriate to allow machinery base drift probably on arbitrary direction 1020mm. Distance between eyelet bolts and foundational hole wall, and between low end of eyelet bolt and hole bottom, must be not less than 15cm. Dimension of eyelet bolt reserve

19、hole refer to table 1.Table 1 Eyelet bolt hole dimension on cross sectionBolt specificationFoundational hole dimensionsSquareCircleM128080100M169090110M20100100120M24120120140M30140140160M36150150170M42160160180M48170170190M56180180200M64190190220(3) There should be no sundry article and water in ey

20、elet bolts holes. Before installing, should cover them to avert any sundry article fall in.(4) Foundation overall dimensions should be inspected, and its elevations relative to factory building and other equipments should fit design.(5) In order to adjust (height of equipment) by fitting spaces that

21、 between foundation and machinery base plate, therefore, foundation elevation should be lower 3050mm than base surface of equipment.(6) In order to get integrative combination between second pour and former foundation, therefore, should shovel surface that will be to second pour and let them become

22、pockmarks (pit diameter may be 3050mm), distance between pits each other may usually be about 150mm. Shovel up notches on their borders of foundation.(7) Foundation treatment(a) Shovel it and cut down by flat shovel when elevation is too higher, shovel up pockmarks and patching pour by former grade

23、of concrete when it is too lower.(b) If eyelet bolts drift, may extend reserve holes, or bake and manifest eyelet bolts as dull red and correct them.1.2 Center marking boardsWhen foundation has been inspected and fit requirements, according to drawings, which have been measured mill and have been al

24、tered, then may fix center-marking boards in foundation. (Note: using the same measuring tool).Center marking boards are usually made from steel rail. I-steel or channel beam (channel bar), their dimensions about (150200mm)(3060mm). Fixed durably them in foundation, then mark out center points, punc

25、h very small holes by puncher (or by theodolite). These holes are regarded as bases of obtaining the positions of equipment for installation.1.3 Datum pointsDatum points are regarded as standard bases of elevations for installation, to measure up their elevations against “zero point of plant distric

26、t”, and make marks on them.Datum points are usually made of rivets, and weld up a piece of 50mm50mm, thickness 10mm of steel plates on the heads of rivets, or weld up two pieces of 50mm long, have been bent of screwy steel. They are buried in predetermined area. Also datum points may be spot welded

27、on relevant reinforced steel bar.1.4 Drawing lines on baseThe requirements of drawing lines on base should be as following:(1) Distance between two crosswise center lines on base of two main bearing its error should be not above 1/10 of mill expansion moreover should be not above 2mm.(2) The positio

28、n of lengthwise center line that is indicated by center marking board, as compared to drawings, their displacement should be not above 3mm.(3) Mill center line must parallel severely to center line of transmission shaft, its error should be not above 0.5mm.(4) Diagonal lines of adjacent bases should

29、 be measured, and adjust them being equal each other, to obtain appearing 90between crosswise centerline and lengthwise centerline each other. 1.5 Hang center lineThe purposes of hanging centerline are to check (positional) relations of every part each other in installing.(1) To check the distance b

30、etween two actual centerlines of main bearings on base plates, and the position of center point of marking board by center marking boards.(2) To check the vertical distance between mill shell centerline and transmission shaft centerline, and the vertical distance between the motor centerline and tra

31、nsmission shaft centerline by center marking boards.(3) To check the positions of the eyelet bolts holes should fit drawing.(II) Installing of eyelet bolts(1) Eyelet bolts should have been cleaned down oil stains and rust, and smear grease on screw threads make antirust. Before installing should ave
