70000448-148 2. CONSTRUCTION AND OPERATING PRINCIPLE 2.1

Construction The thrust device consists of a mechanical part, a hydraulic system and an electrical supervisory and control system. Dependent on the size of the load, the thrust device may consist of  one or several mechanical units, which are mounted on separate supports. If the thrust device consists of more than one unit, only one unit, i.e. the “master unit”, will be connected to the electrical supervisory and control system. The other unit(s) will serve exclusively as “slave units”, which are hydraulically connected only to the master unit. The master unit is always placed on the support closest to the kiln drive. The master unit and slave unit are of identical mechanical design. One On e un unit it co cons nsis ists ts of a rolle rollerr wh whos ose e co coni nica call ru runn nnin ing g fa face ce is in contact with a similar conical running face on the kiln tyre, as well as a hydraulic cylinder which will absorb the axial load exerted on the roller and transmit it to the support. See Appendices 1 and 2. The thrust roller (75) runs in a bearing block (83) which is provided with roller bearings. The suspension of the bearing block from the two guide shafts (81) will allow the bearing block to be displaced in the axial direction. The guide shafts rest in two bearing blocks (80 + 84) which are fixed to the support. The hydraulic cylinder (45) is placed in the bearing block which is closest to the kiln outlet. The roller bearings in the bearing block run in an oil bath. The Th e be bear arin ing g bu bush shin ings gs (82) (82) of th the e gu guid ide e sh shaf afts ts ar are e gr grea ease se-lubricated. The Th e co coni nica call ru runn nnin ing g fa face ce of th the e th thru rust st ro roll ller er is lub lubric ricat ated ed by a weighted graphite block (87) fitted in a holder on the bearing block. The hydraulic system (see Appendix III) consists of a pump station and a pipe system connecting the pump station to the hydraulic cylinder(s). The pump station is a mild-s mild-steel teel frame in which the oil tank as well as pump unit, filters and valve arrangement are mounted. The pipe system consists of a pressure system and a return flow system which can be short-circuited through a needle valve (40). The pressure system incorporates a hydro-pneumatic accumulator  (23). The pri primar mary y fun functi ction on of the acc accumu umulato latorr is to absorb absorb pre pressu ssure re variations in the hydraulic system in case of kiln tyre runout and to ensure that the thrust roller remains in contact with the kiln tyre when the upward migration of the kiln occurs.

 

9 70000448-148 The Th e elec electr tric ical al su supe perv rvis isor ory y an and d co cont ntro roll syst system em co cons nsis ists ts of a longitudinal transducer (49) and two separate limit stop switches (50) and (51). The longitudinal transducer registers the movements of the thrust roller, and hence the movements of the kiln tyre. In case of any upward movement of the kiln tyre, the thrust roller will be moved accordingly due to the hydraulic pressure from the accumulator. The limit stop switches (50) and (51) are actuated, respectively, by the the be bear arin ing g bloc block k th thro roug ugh h an ar arm m an and d by th the e ki kiln ln tyre tyre (see (see  Appendices 6 and 7). 2.2

Opera Operating ting princi principle ple Correctly adjusted, the supporting rollers of the kiln will take up 1050% of the axial load of the kiln. This means that the load on the thrust device will be relieved, but entails also that the remaining load will be exerted on the thrust device, preventing the supporting rollers from forcing the kiln away from the thrust rollers. When the thrust device has one or several slave units in addition to the master unit, the load will be evenly distributed between the th thru rust st ro rolle llers rs du due e to th the e fact fact th that at th the e hy hydr drau auli lic c cyli cylind nder ers s ar are e hydrau hydr aulic lical ally ly inte interc rcon onne nect cted ed.. Th Ther erefo efore, re, th they ey ar are e ca capa pabl ble e of  comp co mpen ensa sati ting ng fo forr th the e ch chan ange ges s in th the e di dist stan ance ce be betw twee een n th the e individual kiln tyres which may be caused by thermal conditions inside and around the kiln. These thermal conditions may, inter alia, be the reason why the kiln tyre at the master unit is moving away from its zero position. Since the primary function of the thrust device is to maintain the kiln in the the ax axia iall dire direct ctio ion, n, it wi will ll re reac actt to th the e ki kiln ln tyre tyre mi migr grat atio ions ns,, attempting to keep the centreline (at the master unit) of the kiln tyre within a range of plus/minus 5 mm from the neutral position. Minor  movements within this range - due, for example, to kiln tyre runout will be taken up by the hydraulic accumulator. For equipped with gear the neutral position will coincide with kiln the centreline of thegirth supporting rollers. For a kiln with drive effected through the supporting rollers, the neut ne utra rall po posi siti tion on wi will ll be disp displa lace ced d fr from om th the e ce cent ntre reli line ne of th the e supporting rollers to compensate for the weight of the drive unit. See the position drawing drawing of kiln for the posi position tion of the neutral point relative to the centreline of the supporting rollers.

 

10

70000448-148 The thrust device will react to the movements of the kiln tyre/kiln in the following manner:  A downward downward movement  movement of the kiln tyre, out of the neutral zone, will trigger the following action: The longitudinal transducer (49) registers the movement. The oil pump (08) is started, thrusting the kiln upward again, back to the neutral zone. See fig. 1. Fig. 1

 

70000448-148

11

The oil pump will be stopped when the kiln tyre has reached the zero position. The hydraulic pressure will then be exerted on the non-return valve (11). This operating situation will prevail as long as the kiln/kiln tyre are positioned in the neutral zone. See fig. 2. The system pressure must now be 50 – 70 bar. Fig. 2

 

12

70000448-148  An upward upward movement  movement of the kiln tyre, out of the neutral zone, will trigger  the following action: The Th e long longitu itudi dina nall tr tran ansd sduc ucer er (4 (49) 9) wi will ll re regi gist ster er th the e mo move veme ment nt.. Th The e accumulator will ensure that the thrust roller maintains contact with the kiln tyre. The solenoid-operated directional seat valve (13) is energized. The Th e oil oil fr from om th the e hy hydr drau auli lic c cy cyli lind nder ers s an and d ac accu cumu mula lato torr ca can n no now w be reci re circ rcul ulat ated ed th thro roug ugh h the the syst system em ba back ck to th the e ta tank nk.. (See (See Fi Fig g 3) 3).. Th The e pressure transducer (18) will trip alarm in case of a pressure drop to level below 10 bar. The pressure will not drop to a level below 3 bar because of the nonreturn valve (30). If the kiln is unable to move downward unaided, it will be necessary to adjust the position of the supporting rollers. When Whe n thr thrust ust roll roller/ er/kil kiln n tyr tyre/k e/kiln iln hav have e mig migrate rated d dow downwa nward, rd, bac back k to the neutral zone, the voltage from the solenoid-operated seat valve must be de-energized, and, again, the hydraulic pressure will be exerted on the non-return valve (11).

 As far as the electrical control system is concerned, reference is made to electrical diagrams and circuit diagrams. If, in spite of the thrust thrust dev device ice,, the kil kiln/k n/kiln iln tyre is movi moving ng more than 10 mm downwards from the zero position, the longitudinal transducer will trip an alarm. The kiln motor will be cut out in event of a further 5 mm downward migration of the kiln/kiln tyre. See the functional diagram in Appendix 4. When the kiln is shut down, the valve (40) must be opened/closed every 24 hours in order to equalize the pressure between between the front side and back side of the piston. This is done to prevent ingress of  dirt and moisture into the cylinder.

70000448-148 3. INSTALLATION 3.1

Installation of the mechanical parts It is a prerequisite for satisfactory operation of the thrust device of  kiln that the kiln supporting rollers have been correctly adjusted, as described in the erection manual for supporting rollers, ref. 9. It is also very important that the fine alignment of the kiln tyre(s) with which the thrust device is in contact has been carried out very carefully. Functionality of the master unit during the erection of kiln is very impo im porta rtant nt,, i.e i.e.. so th that at it ca can n re rest stri rict ct th the e mo move veme ment nt of th the e kiln kiln towards the outlet. Therefore, the master unit must be mounted at earl ea rlie iest st po poss ssib ible le st stag age e af afte terr su supp ppor orti ting ng ro roll ller er be bear arin ings gs an and d supporting rollers have been mounted. The mounting of slave units can take place at subsequent point in time, when deemed appropriate in relation to the overall erection process. The master and slave units as well as pump station arrive at site as prea preass ssem embl bled ed un unit its. s. Th The e hy hydr drau aulic lic cyli cylind nder er is su supp ppli lied ed wi with th a magnetic scanner fitted in the piston. The thrust roller must not be dismantled during erection. After a unit has been released from the transport frame (96) (see Appendix 1), it must be mounted in the assembled condition on the bedplate. Follow Fol low the dir direct ection ions s giv given en on the arra arrange ngemen mentt dra drawin wing g of the thrust device. At some supports, the unit must be mounted on a bracket which must first be mounted on the bedplate. Mount the oil level pipe (85) and air filter (94) on the unit, and fill oil into the bearing housing up to the mark on the oil level glass (See  Appendix 2). Oil quality: FLS MAT No. 7158. Mount the masterThe unitthrust on the bedplate or on the bracket mounted on the bedplate. roller must be positione positioned d at the correct distance away from the centreline of the supporting rollers. The bearing block of the unit must be centrally positioned on the guide shafts, i.e. the dimensions "a" and "b" must be of equal size. See Fig. 1. Distance pieces of identical size are fitted at "a" and "b" to facilitate the operation. See Appendix 1. ERECTION CHECK  Align the thrust roller so that its rate of iinclination nclination is consistent with that of the kiln and so that it will be horizontally positioned at right angles to the kiln axis. The axis of rotation of the thrust roller must be exactly in the vertical plane of the kiln. See Fig. 4 .

Force the thrust roller into contact with the kiln tyre, and make any necessary adjustments. Remove the distance pieces at "a" and "b" and mount the four twopart distance rings (90) on the guide shafts for the master unit. These distance rings, which will restrict the migration of the bearing lock, must only be mounted on the master unit. See Appendices 1 and 4. The contact level between thrust roller and the kiln tyre must be checked in the immediate aftermath of kiln tyre installation. ERECTION CHECK Fit the adjustment wedges (91) and fix them by welding to the bedplate as indicated in Appendix 2. Fit the holder (86) for graphite block (87), guard (95) for cylinder  block and the two-part channel (88).

Instal Installati lation on of the hydrau hydraulic lic system See separate instruction manual: Hydraulic installations, ref. 5, 6 and 7. Install the pump station as indicated on erection and foundation drawing and Fig. 5. Connect the pump station and thrust roller to the supplied hydraulic pipes in strict accordance with the pipe diagram. Prior to shipment, the pipes have been cleaned, rust-proofed and plugs have been fitted at pipe ends. The Th e prote protect ctiv ive e plug plugs s at pipe pipe en ends ds mu must st re rema main in fi fitt tted ed un unti till th the e installation of the pipe system is about to take place. Fig. 5

 All grates and shavings formed in connection with the adaptation of  the pipes must be removed very carefully. If the pipes are not mounted immediately after adaptation, they must be closed with plastic plugs. These plastic plugs must remain fitted until installation of pipes is imminent, with renewed checking of pipes to ensure that they are absolutely clean. Welding, soldering etc. on pipes must not occur after the pipes have been installed. The hydraulic cylinders (45) must be mounted in the cylinder block (83) so that the venting holes are positioned at highest possible levels. The venting holes are used in connection with the venting and an d te test stin ing g eq equi uipm pmen ent, t, an and, d, th ther eref efor ore, e, th the e ho hole les s mu must st be positioned in manner providing the necessary space to accommodate the equipment. The cylinder is retained in the cylinder block by a five-part locking ring (92). A screw – together with the cover ring – will prevent the cylinder from turning. It is of par param amou ount nt imp impor orta tanc nce e to av avoid oid an any y for foreig eign n matter in the hydra raul ulic ic sy syst stem em.. Th Ther ere efore, it is essential to avoid contamination of pipes and fittings. See separate instruction manual for hydraulic installations, ref. 5. Use only hydraulic oil of a quality correspond corresponding ing to FLS MAT No. 7025.

The magnet (46) and plastic disc (47) are mounted in the piston by the supplier of  the hydraulic cylinder. The longitudinal transducer is mounted in the protective tube. Calibration of the longitudinal transducer has been carried out by the supplier. Electrical connections from the longitudinal transducer  must be established as specified in the electrical documentation. If recalibration of the longitudinal transducer should be required, this must be done locally. Such Su ch ca cali libr brat atio ion n mu must st be ca carri rried ed ou outt in ac acco cord rdan ance ce wi with th th the e directions given in the transducer instruction manual. When calibration is carried out, the piston should be pushed to the bottom of the cylinder, see Appendix 8. When the thrust roller is in 0-position, the distance, K, must be measured between the thrust piece (97), and “bottomed” piston. This position corresponds to ”a” = ”b” as indicated in Appendix 4. The transducer must be released from the protective tube, pulling it parti pa rtial ally ly ou outt of the the tu tube be,, to th the e ex exte tent nt of th the e di dist stan ance ce K, se see e  Appendix 8 Fig. 1.

Thr Thrust ust dev device ice fai failur lure e Each thrust roller is individually capable of absorbing the full axial load of kiln during a short period of time. In ca case se of oil oil pu pump mp fa fail ilur ure, e, th the e hy hydr drau aulic lic pr pres essu sure re wi will ll stil stilll be maintained due to the non-return valves of the system. In event of pump failure or pump motor failure when the kiln is in ”exc ”e xces essi sive ve up upwa ward rd po posi siti tion on”, ”, th the e kiln kiln can can be ma made de to mig migra rate te downward by manually setting the pressure-limiting valve (21) for a very low pressure.

 

26

70000448-148 If the pump or pump motor should fail when the kiln is "in downward position", posit ion", and the kiln must be lifted to neutral neutral position, this can be done by means of a hydraulic hand pump which is connected to measuring nipple (20) or (42). The ha hand nd pu pump mp mu mus st on only ly be ope pera rate ted d wit ith h ver ery y sm smal alll oi oill quantities. In case of a pipe rupture on the pressure side, the kiln will force the thrust rollers downward towards the outlet, until the bearing block of  the master unit is made to rest on the distance ring (90). At this poin po intt in ti time me,, an alarm larm ha has s alr lre ead ady y be been en tr trig igge gere red d by th the e monitoring system, and if no further action is taken, the kiln motor  will be cut out automatically. 5.2.2

Kiln tyre runou runoutt  During kiln operation the hydraulic accumulators will compensate for any kiln tyre runout. The extent of kiln tyre runout during one kiln revolution can be read off on the guide shafts of the bearing block. To so some me de degr gree ee,, th the e ac accu cumu mula lator tors s wi will ll eq equa ualiz lize e th the e pr pres essu sure re variations varia tions occurrin occurring g as a result of the runout. Subs Substantia tantiall pressure pressure vari va riat atio ions ns du duri ring ng on one e kiln kiln re revo volu luti tion on will will be an in indi dica cati tion on of  accumulator damage, The pressure variations recorded while the accumulator is in operation must be much smaller than when the cylinder, and hence the accumulator, is disconnected. The pressure pressure var variat iation ions s in a cyl cylind inder er can be che checke cked d wit with h the pressure gauge (33) mounted on the measuring nipple (42) on the pressu pre ssure re sid side e of the cyl cylind inder er whe when n the cylind cylinder er is dis disonn onnect ected. ed. Disconnection is accomplished by closing the valve (41) for the specific cylinder. See Appendix 3. Valve (41) must be opened entirely on completion of  the check-up procedure.

5.2.3

Position of supporting rollers In case the load on the thrust rollers is extremely large or extremely small, this will normally be ascribable to the fact that the supporting rollers are no longer positioned exactly as they should be. Exact positioning posit ioning of the suppo supporting rting rollers is of crucial importanc importance e for the operation of kiln and thrust device. See instruction manual for axial measuring equipment, ref. 8.

Posit Position ion of the thrus thrustt roll rollers ers It is very important that the thrust rollers tread with their entire con onta tact ct su surf rfa ace ag agai ains nstt th the e kil iln n tyre tyres. s. If an adj djus ustm tme ent is necess nec essary ary,, it mus mustt be don done e by ins insert erting ing interm intermedia ediates tes bet betwee ween n thrust device and bearing block. It is also essential to ensure that the diameter of the thrust rollers at right angles to the roller kiln axis – is horizontal, andplane that the axiskiln of  rotation of the thrust is lying in the vertical of the axis. Non-compliance with these conditions will result in an effect similar  to that occu occurring rring in case of ”skewing ”skewing”” of a supportin supporting g roller, i.e. the thrust roller will either follow the kiln tyre some distance upwards or  the the pres pressu sure re wh whic ich h is ex exer erte ted d in do down wnwa ward rd di dire rect ctio ion n wi will ll be exceptionally large.
