Main branch-circuit fuses provide overcurrent protection in the event of short-circuits, power surges, damage to electrical wiring, etc…by interrupting faulty circuitry and removing it from the electrical system. In addition, the molded case switch can disconnect power from the source prior to known electrical disturbances, before the fuse is required to operate. Integrated into the molded case switch is an electromagnet (shunt trip coil), controlling a spring-loaded conductivestrip which maintains continuity between the line side and load side terminals of the switch. The electromagnetic coil is normally connected to a safety system, such as a fire alarm or smoke detector housed in the surrounding building. Should there be an electrical emergency, a signal is sent to the coil (via the safety system, alarm, sprinkler, etc…) and the electromagnet would be engaged, throwing the switch and disconnecting power. Power can only then be reenergized by manually operating the molded case switch. • Fusible Shunt Trip Switch 3D A N g e r A N D WA r N I N g L A b e L SU L L I S T I N g I N F O r M AT I O NStep 1: Disconnect power from the circuit where the fusible shunt trip switch will be installed. Mount the panel. Wire up the line side three phase conductors into the three line side terminals of the molded case switch (L1, L2 and L3). Wire the load side to the three load side terminals of the class J fuseholder (T1, T2 and T3).Step 2: Wire the remote control elements to the specified terminal blocks shown in the wiring diagrams on page 6 and 7 (120VAC and 24VAC/DC respectively) of this manual. For 120VAC, safety system controls must supply a set of dry (no voltage) contacts. For 24VAC/DC, safety system controls must provide the voltage source.Step 3: Connect power to the circuit on which the fusible shunt trip disconnect switch is installed. T est the shunt trip operation. Close the molded case switch manually; the pilot light (if installed) indicating that the switch is closed will indicate. engage the key switch (if installed) to activate the shunt trip and trip the molded case switch. The switch will trip and the pilot lightwill turn off.e S S e r I e S–F U S I b L e S h U N T T r I P D I S C O N N e C T S W I T C hFire Alarm Voltage Monitoring relay included in all Mersen offerings. No additional part suffixes required. (Competitor Options F1 and F3)*Neutral lug rating should be greater than or equal to the switch ampere rating. For 200% lug over sizing, select next higher rating. N4 is suitable for 200% over sizing at 400A. • Fusible Shunt Trip Switch • Fusible Shunt Trip Switch 5Minimum – This sizing is recommended if motor acceleration time does not exceed 2 seconds. Minimum sizing with class J fuses will provide overload relay back up protection but may not coordinate with some NeMA Class 20 overload relays. Minimum sizing is generally not heavy enough for motors with code letter g or higher.Typical – Suggested for most applications. Will coordinate with NeMA Class 20 overload relays. Suitable for motor acceleration times up to 5 secondsHeavy – Maximum allowable fuse size when an overload relay or motor thermal protector is included in the branch circuit. If this fuse size is not sufficient to start the load, class J time-delay fuses may be increased to a maximum of 225% of full load amperes. Suggested for Design e and high efficiency Design b motors.Notes:1. Tb-5 and Tb-9 must be dry (no voltage) normally open contacts from safety system2 . If a surge protection option is selected, it will be corrected line to ground between the STS and fuses F1-F3 • Fusible Shunt Trip Switch • Fusible Shunt Trip Switch 7Notes: 1.For 24VAC control systems, 24VAC must be connected between Tb-5 and Tb-3. For 24VDC control systems, 24VDC must be connected between Tb-5 and Tb-3. Do not source AC voltage into a DC control system or vice versa.2 .If a surge protection option is selected, it will be connected line to ground, between the STS and fuses F1-F3. • Fusible Shunt Trip Switch • Fusible Shunt Trip Switch 9M A I N T e N A N C eThe following preventative maintenance measures should be considered in order to maintain product integrity •Periodically clean product exterior and interior to remove any dust, particles, tools or other. Follow proper safety precautions when performing maintenance.•Periodically check lug torque values in order to maintain product specifications. recommended torque values for all parts are shown on page 8 of this manual. Follow proper safety precautions when performing maintenance.•Preventative maintenance may include thermal-scan imaging in order to identify any “hot-spots” or generation of excessive heat. Any temperature increase, not related to load variations or ambient temperature could signal a problem with lug torque.•Maximum temperature at any lug should never exceed 75ºC under any conditions.WA r r A N T yMersen warrants to the buyer that products and any services furnished hereunder will be free of from defects in material, workmanship and will be of the kind and quality specified in Mersen standard terms and conditions.

If you have any questionsregarding the field wiring diagram, please contact Schold Manufacturing at1-800-4-MIXERS.5.3 DIRECTION OF ROTATIONWARNING: NEVER TOUCH ROTATING PARTS. FAILURE TO OBSERVE THIS MAY RESULTIN BODILY INJURY.WARNING: USE SPECIAL CARE WHEN HANDLING THE MIXING ASSEMBLY – THE BLADE AREA MAY BE SHARP!The mixer must be wired to ensure that it runs in the correct direction. The direction should be clockwise when viewed from the top of the motor. (See figure below) WARNING: ENSURE THAT THE MIXER IS ISOLATED FROM THE ELECTRICAL SUPPLYBEFORE CARRYING OUT THE FOLLOWING PROCEDURE:1.Before attempting to start the machine, ensure the drive shaft can be turned freely.This is carried out by carefully rotating the mixer shaft clockwise by hand. Make sure to avoid the sharp blade area. If the drive shaft does not turn freely, consult Schold Manufacturing.2.If everything is in order, reconnect the electrical supply and check for direction ofrotation.3.To jog, press the START button on the starter and IMMEDIATELY press the STOPbutton. This will make the motor turn only two or three revolutions – sufficient to view the direction of rotation. The direction should be clockwise when viewed from the top of the motor.4.If the motor rotates in the wrong direction, swap any two of the input phase linesand repeat the procedure given above. Changing the input leads into the VFDtypically will not change the rotation. Wiring must be changed between the VFD output and motor input.OPERATION _____________________________________________________________________________________ 6 OPERATIONWARNING: DO NOT USE THE MACHINE IN A HAZARDOUS AREA WHERE A FLAMMABLE OR EXPLOSIVE ATMOSPHERE MAY BE PRESENT UNLESS THE MACHINE IS FITTED WITH AN EXPLOSION PROOF MOTOR RATED TO THE RELEVANT STANDARD FOR THAT AREA.WARNING: USE SPECIAL CARE WHEN HANDLING THE MIXING ASSEMBLY – THE BLADE AREA MAY BE SHARP!1.Secure vessel in place with the tub holder arm and chain. Extend the tub holder armand wrap the chain tightly around it the vessel. Make sure it is centered with respectto the mixing blade and it is rigid in place.2.The operation panel (See figure below) consists of the following components:• A lever to move the mixer up and down• A knob to adjust the rotational speed of the mixer shaft.• A green button to start the mixer, a red button to stop the mixer•An emergency stop button to stop the mixer.WARNING: MAKE SURE THE SAFETY SWITCHES ARE WORKING3.The amps readout of the motor is shown from the readout above the operationpanel. It is displayed as a percentage.4.Do not operate without guards. The height of the shaft guard is adjustable toaccommodate various vessel sizes. Adjust the shaft guard height by unscrewing theknob, sliding the shaft guard to the desired location, and finally screwing the knobtightly back in place. (See figure below)5.Make sure the supplied air is a minimum of 80 PSIG. Lower the blade completelyinto the vessel. Start rotating the blade at a low speed. Do not attempt to start theblade in high or max speed setting. Never allow the blades to rotate above theproduct.6.Always turn the mixer down to the lowest speed setting before shutting off.6.1 MIXING TIPS•Always start the mixer at a low rotational speed setting.•Ramp up the speed to the desired speed, but make sure to never exceed 100% on the motor readout.•If high motor loading is hindering mixing, then run at a low speed setting until the product heats up. This decreases its viscosity, and allows higher speeds of mixing.6.2 CLEANINGThe LMX mixer is in most cases self-cleaning, a short run between successive mixingoperations in water, detergent or an appropriate solvent should be all that is necessary to clean the wetted parts. For more thorough cleaning, dismantling is easy anddowntime minimal.WARNING: THE MIXER MUST BE ISOLATED ELECTRICALLY BEFORE IT IS DISMANTLEDFOR INSPECTION OR CLEANING.The wetted parts can be cleaned with plant standard cleaning agents provided that they are non-scratching. Do not scour the parts with sharp objects.If the machine is to be left idle for any length of time it should first be thoroughlyflushed by running for a short time in a suitable cleaning agent to wash any solids from the blade and shaft end.WARNING: IF IT IS NECESSARY TO USE FLAMMABLE SOLVENTS TO CLEAN MIXEDPRODUCT OFF THE WETTED PARTS, THEN THE MIXING ASSEMBLY MUST BE REMOVED AND CLEANED IN A SAFE AREA, AWAY FROM THE MOTOR AND FRAME.WARNING: THE COMPLETE MACHINE ASSEMBLY SHOULD NEVER BE SPRAYED WITHWATER NOR IMMERSED IN WATER.The materials of construction of the wetted parts are compatible with all commonlyused cleaning chemicals.Most sanitizing chemicals, such as those that contain active chlorine, iodine, etc. arecorrosive, to some extent to stainless steel. Where these chemicals are used, 316Stainless Steel should be specified.WARNING: SUITABLE PROTECTIVE CLOTHING SHOULD BE WORN WHEN HANDLINGAND USING CLEANING CHEMICALS. NATIONAL, LOCAL, AND SITE REGULATIONSSHOULD BE OBSERVED.MAINTENANCE _____________________________________________________________________________________ 7.1 GENERAL MAINTENANCEMachines should always be cleaned after use. As a general guideline, where a machine is being used repeatedly to process the same material it will be sufficient to run themachine for a short time with water, detergent or a suitable solvent or flushing agent.If the machine is to be left idle for any length of time it should first be thoroughlyflushed by running for a short time in a suitable liquid to wash any solids from the blade and shaft end.7.2 ASSEMBLY AND DISASSEMBLY OF MIX BLADEWARNING: BEFORE PERFORMING ANY ASSEMBLY/DISASSEMBLY PROCEDURE,ISOLATE THE UNIT ELECTRICALLY. THIS OPERATION SHOULD BE CARRIED OUT BY AQUALIFIED ELECTRICIAN.WARNING: USE SPECIAL CARE WHEN HANDLING THE MIXING ASSEMBLY – THE BLADE AREA MAY BE SHARP!The LMX mixer’s blade assembly can be removed. To remove the blade assembly,unscrew it from the bottom of the shaft by twisting it clockwise when viewed fromabove. (See figure below)If any major fault develops, the mixer should be returned for repair and/or service. The mixer must be shipped suitably packed and with the approval of Schold Manufacturing.If you have any questions, please contact Schold Manufacturing at 1-800-4-MIXERS.7.3 RECOMMENDED SPARE PARTSThe LMX mixer’s blade can be easily replaced, and it is recommended to store a spare low speed bow tie blade assembly.LABELED PARTS_____________________________________________________________________________________ 9 DRAWING WITH LABELED PARTS。

1-TRM(莱歇)立磨LM46×2C
12.主要设备施工技术方案12.1LM46C/S2+2莱歇立磨施工技术方案12.1.1概述12.1.1.1莱歇立磨的特点原料粉磨是水泥厂工艺线上极为重要的环节,磨机安装质量的好坏,直接关系到全线生产能否正常和全厂投产后的经济效益。
莱歇立式辊磨机主要特点如下:带有耐磨衬板的平磨盘与锥形磨辊,采用4辊液压式,为便于磨机检修,磨上附有翻出磨辊用的轻便型油压装置;磨机负荷运转在起动时磨辊能自动从磨盘上提起,减少了起动转矩;磨机设有保护装置,当辊压超过或低于调定范围极限值时,自动报警并自行停磨,确保磨机安全运行;磨机液压系统具备自动控制和手动控制两种功能,可提高操作上的灵活性、可靠性;各磨辊有独立的液压加压装置,每个液压缸都配置了足够的蓄能器,保证磨机运转中辊压波动最小,以使磨机运转平稳;分离器采用直流电机传动,改变转速即可满足各条件下对产品细度的要求,细度调节灵活方便。
风环设计成可调节的,改变风环截面积可以调节风环风速,适应不同物料;磨辊辊套与轮毂之间,以及辊轴与摇臂之间分别采用锥面结构和胀套结构连接,拆装方便。
和球磨机相比,该磨的主要优点是:具有更高的研磨效率,工艺流程大大缩短,电耗降低,物料的研磨在限定压力下进行。
12.1.1.2莱歇立磨的工作原理主电机按设计功率旋转通过齿轮箱带动磨盘转动,原料从磨机三门装置喂入,落到磨盘中央,然后在离心作用下甩到辊子下边,在磨盘外边的挡圈使原料形成了层状,称为粉磨床。
辊子与磨碗间的压力由液压装置施加,物料层带磨辊转动产生连续不断挤压生料的作用,粉磨后的物料越过挡圈落下,这时用于烘干物料的热风从磨盘下引入,从环向缝隙吹起细料,这时上升的气流把扬起的物料带到磨机上部的离心式选粉机里进行粗细分离,粗粒落回粉磨室中央再次粉磨,细粉则随气流排出磨外。
由于磨机从主电机水平传动经大型齿轮箱转换后带动装有扇形耐磨衬板的磨盘按垂直回转轴线的连续旋转,而上部选粉机壳体靠磨机筒体支撑,选粉机立轴带着转子也按同一垂直回转轴线连续旋转。
NHP型喷雾降温系统的应用
运行时,烟气由高温风机经生料磨后进入袋除尘器
4.由于在高温风机上游喷雾,进入高温风机的烟
气温度降低,保护了高温风机。经喷雾后,烟气密
度虽有所增加,但由于温度降低,烟气体积减少, 高温风机电机电流没有增加,即风机负荷未增加。

LM32.40莱歇磨的启动作者:王银山孙春生山西水泥厂1 情况简介山西水泥厂2000t/d熟料新型干法生产线的生料制备,使用引进FULLERF.L.S公司的LM32.40莱歇磨,生产能力160t/h。
其粉磨效率高,入磨物料粒度大,工艺简单,但其操作控制比较困难,特别是磨机启动方面。
1.1 工艺流程物料从预均化堆场和联合储库由皮带输送机分别送至配料站,配料站下由4条皮带秤(砂岩、铁粉、石灰石、混合料)将物料按设定比例卸到入磨皮带上,经三道阀进入磨内。
烘干粉磨后合格生料(经磨内选粉机)在风机6的作用下,送至旋风筒4及收尘器8,收下的物料经F—K泵输送至均化库。
废气由风机9排入大气。

初期由于磨辊低、出口温度低、油泵等故障,特别是振动大的问题,连续启动十几次都无法成功(启动即跳)。
后经加装磨盘喷水,减小振动,才使磨机得以启动。
截止1995年9月23日调试完毕。
据不完全统计,其间共运行71.43h,开停合计127次,其中启磨跳停41次。
1995年10月29日正式试生产,操作员在外方专家的指导下进行操作,截止1996年2月20日,共运行427h。
期间影响磨机运行的故障有:(1)油泵压力和温度故障;(2)水泵压力报警;(3)混合料仓堵塞等。
启磨故障主要是振动和辊位低,尤其是振动故障占总故障的34.1%。
1996年2月21日以后针对振动大的问题调整辊子压力(设定为53.5kg/cm2调为52.5kg/cm2),严格控制入磨物料粒度,使振动影响启磨故障减少。
但由于磨盘的磨损,间隙增大。
因辊子低引起启磨跳停次数增多故障率升高,占运行故障的27.5%。
常因启动不了磨机被迫减少投料量,甚至停窑。
1996年10月检修换掉了第一套磨盘和外方专家撤走后,由我厂操作员独立进行操作控制,并对辊子间隙合理调节,优化操作方法,使1996年10月30日至1997年6月30日磨机运转率大大提高,故障率降低。
但振动大和辊位低启磨跳停故障率依然居于首位(各阶段启磨及运行情况见表1),影响了生料的生产和回转窑的正常运行。
所以,控制磨机启动时的振动和辊位优化操作方法,是保证磨机正常运行的关键,对提高运转率、稳定生产十分重要。
表1 莱歇磨启动及运行状况注:1995年3月23日~9月23日统计数据为磨机可连续运转以后的数据,初期启磨调试数据不包括在内。
2 引起磨机振动过大和辊位偏低的原因分析在生产过程中,莱歇磨振动值一般控制在4~8mm/s。
一旦超过10mm/s(设计正常范围<12mm/s,19mm/s时报警)要及时调节。
否则,有可能使振动值迅速增大,超过22mm/s时磨机跳停。
在磨机启动时,如控制不当,振动值的波动就大。
如何使启动磨机时振动值在短时间内控制在4~8mm/s就成为启磨的关键。
影响磨机启动跳停次数最多的是辊位偏低故障,特别在试生产后期尤为明显,影响磨机启动时产生振动过大和辊位偏低主要有以下几个方面的原因。
2.1 预充料在磨机启动时首先要预充料,预充料的多少关系到磨机是否能顺利启动。
预充料多时易引起磨机振动大而跳停,甚至充料太多时压死磨盘。
预充料太少时会使磨机辊位偏低,造成限位报警而停磨。
另外,预充料的次数很重要,特别是清完磨盘时的预充料,如不能一次充好,多次充料的情况下,可能造成入磨皮带多处断料,在启磨时因皮带断料造成磨盘上物料少而辊位偏低跳停。
2.2 系统风量同预充料不能相适应如磨内预充料太多,物料的易磨性较差时,在磨机启动的瞬间,系统风量过小会造成磨机过负荷振动跳停,如预充料太少料太细,启动磨机时风量过大,会导致磨盘上的物料瞬间过少,喂料又不能及时补充,料层变薄,这会使辊位偏低而自动停磨。
2.3 物料的粒度和易磨性物料的粒度大,超过90mm的量占15%以上,特别是砂岩粒度太大时,占总量5%的粒度超过90mm就易引起磨体振动超过极限值而启磨即跳。
当入磨物料太细,料层低,特别是停磨后不清磨盘,预充料量少的情况下,由于磨盘上存的料全为粉状物料,预充料又因细形不成料床,最易造成辊位偏低而跳停。
2.4 选粉机转速选粉机转速较高,在磨盘上预充料的颗粒较粗,物料多时,由于负荷大,易引起磨体振动超过极限值而跳停。
入磨物料和选粉机转速与上述情况相反时易使辊位偏低跳停。
2.5 磨盘喷水磨盘喷水是物料在磨盘上形成一定的料床和减振设施。
如启磨时喷水量小或不能喷水,物料太细时易使辊位偏低,物料太干且粗时易使磨机振动大启磨即跳。
2.6 磨辊的液压弹性压力及辊子间隙磨辊的液压弹性压力也是导致振动过大和辊位偏低的一个因素,弹性压力低影响磨机的产量。
如充料太多就会产生振动;弹性压力太高,易使辊位低。
间隙太小易使振动值大,影响磨机启动。
2.7 入磨温度磨机启动时,辊子落下后,喂料皮带喂料。
出磨温度低时,喂料就得减少,使料层变薄会导致辊子太低而磨跳停。
如磨机启动进入的热量太多,用增加喂料来降低出口温度,也会因料太多而振动大使磨跳停。
3 磨机启动时各参数的调节与控制前面简介了磨机启动时,引起振动和辊位低的主要原因。
那么,如何解决启动中存在的问题,克服引起振动和辊位低的可能因素?这就要合理调节控制磨机启动的参数,使其在正常的范围。
LM32.40莱歇磨主要控制回路及参数见表2。
表2 主要控制回路及参数3.1 预充料的控制预充料时间的控制,一般以170t/h的喂料量启动预充100~120s,预充料量在2.6±0.2t范围内。
料的多少要视磨辊的间隙、物料的粒度和易磨性等情况而定。
当物料较粗,辊压较高,易磨性较好,磨辊间隙较大时充料时间取上限值;否则,易使磨辊太低,磨启动即跳;当磨辊间隙较小,物料易磨性较差,磨辊的液压弹性压力较低时充料时间和充料量取下限值为宜。
否则,易引起磨机振动,启动即跳。
物料要尽可能一次充好;入磨皮带速度相对要低,以防止入磨皮带断料。
预充料后,要打开磨门检查确认预充料合理方可启磨。
3.2 物料粒度的控制严格控制入磨物料的粒度,使入磨物料粒度控制在95%小于75mm。
杜绝大于90mm的石灰石,特别是砂岩(本系统入磨皮带上装有除铁器和金属探测仪,保证无金属进入磨内)的破碎一定要小于75mm。
3.3 系统风量的控制调节系统风量的控制主要依据磨机预充料的多少、物料粒度及磨机进出口温度而定,主要表现在磨机磨辊落下时磨机的负荷及进出口差压的大小。
负荷大于75%、磨机的进出口差压大于900mmH2O(8820Pa)。
磨机出口温度小于66℃时及时将磨风机阀门开度输出值增加即由85%→90%→95%→100%(开始输出值85%)。
相应提高磨废气风机控制回路的设定值至-70mmH2O(-686Pa)或-80mmH2O(-784Pa)。
也可手动控制,将转速输出到70%或80%。
待磨机正常运行时将磨风机阀门控制(旋风筒差压控制回路)打入自动。
废气风机转速—窑尾风机出口风压控制回路(设定压力)减到窑需要的最佳值,以防过载引起振动跳停。
当启磨辊子落下后,磨机负荷小于80%,进出口差压小于650mmH2O(6370Pa)、出口温度高于80℃时,要及时将磨风机阀门—旋风筒差压控制回路打入自动,将设定值输入-190mmH2O(-1862Pa),并适当增加喂料量,以确保辊位不低。
必要时,如磨机的出口温度太低可适当增加窑尾引风机的转速1%~2%(通过窑操作员),以确保磨机的出口温度。
3.4 选粉机转速的调节与控制选粉机速度的控制主要依据物料的情况来调节。
当物料较粗,颗粒较大时充入磨内的料较多,选粉机的转速相对要调低3%~4%。
启磨在辊子放下时若磨机负荷超过95%,要待负荷低于90%时方可增加速度,在超过100%时且振动较大,要立即降低1%~3%,防止过负荷振动大跳停。
物料较细,预充料较少时,选粉机转速不应调低,否则,易使磨辊太低而跳停。
磨机启动运行平稳后方可将选粉机转速控制在正常范围。
3.5 辊子间隙控制辊子间隙一般在25mm为佳,随着磨盘的磨损,间隙逐渐增大,要定期调整以保证磨机的产量能控制在110~160t/h之间为好,如充料过多又会压死磨盘。
为此磨辊间隙一定要合理。
3.6 磨机进出口温度的控制从调试情况看,磨机进口温度低于130℃(拉风后),进入磨机的物料烘不干,使出口温度低而报警,被迫减料,这时由于料层较薄而磨机启动后稳定不住,易使磨辊太低跳停。
为此,必须进口温度能大于130℃以上时方可启磨,这种情况只在试生产初期,窑投料低于80t/h时会出现。
产量提高后由于从预热器一级筒引出的废气温度高达400℃,磨机进口温度高达300℃以上。
为此在磨机启动拉风过程中就会使出口温度长时间过高(大于90℃),使磨不能启动,即使启动也会因出口温度过高而跳停。
这时要开大磨盘喷水,保证磨体喷水正常。
风机排风量低限拉风下启磨(废气风机阀门—窑尾排风机出口压力控制回路设定-30mmH2O(-294Pa)。
磨风机阀门—旋风筒差压控制回路输出70%或80%,保证不因出口温度高而启磨即跳。
4 结束语影响磨机启动时振动和辊位低的因素不是独立存在的,而是相互联系、相互影响、相互制约的,对影响因素的控制调节必须相互兼顾、综合考虑,不要顾此失彼,而且在启磨时判断要准。
对各种参数利用控制回路及时进行调整,方能提高莱歇磨启动的成功率,保证生产的正常进行。
