  • 5. What is cement <ul><li>Cement can be defined as any substance can join or unite two or more pieces of same other substance together to form a unit mass. </li></ul><ul><li>Cement as used in construction, is a fine powder which when mixed with water and allowed to set and harden can join different component to give mechanically strong structures. </li></ul><ul><li>Cement clinker are two products, when clinker grinned with gypsum gives ( O.P.C ) ordinary Portland cement </li></ul>
  • 6. Raw material of cement <ul><li>Lime stone </li></ul><ul><li>High grade lime stone </li></ul><ul><li>Bauxite </li></ul><ul><li>Blue dust </li></ul><ul><li>Silica </li></ul><ul><li>Iron ore </li></ul>
  • 7. Mines <ul><li>There are two mines. The mines area spread </li></ul><ul><li>at 9km^2. Which is rectangle of 1 km wide & </li></ul><ul><li>9 km length. </li></ul><ul><li>Detail about mines:- </li></ul><ul><li>Mineral dressing & size reduction :- </li></ul><ul><li>Removing unnecessary material like mud, soil, & low grade lime stone. </li></ul><ul><li>Mining :- </li></ul><ul><li>Before it lots of work done, Removing overburden in open cast mining. </li></ul>
  • 8. <ul><li>Over burden Removal </li></ul><ul><li>Bench marking </li></ul><ul><li>Drilling </li></ul><ul><li>Blasting & </li></ul><ul><li>Transportation of lime stone to crusher. </li></ul>
  • 9. Crusher <ul><li>Crusher is size reduction unit. </li></ul><ul><li>Single rotor, impact type in which lime stone is crushed about 6cm to 8cm. </li></ul><ul><li>Dc power transmission is given through v type belts. </li></ul><ul><li>It has 6 blow bar . </li></ul><ul><li>Each weight is 504 kg. </li></ul><ul><li>There are sieve (vibrating screen), which reject the lime muddy & heavy in weight . </li></ul>
  • 10. Crusher <ul><li>Type : Single rotor impactor </li></ul><ul><li>Capacity :550 TPH </li></ul><ul><li>RPM :1000 </li></ul><ul><li>Now the material from the crusher transferred through belt conveyor to stacker & reclaimer unit . </li></ul><ul><li>The reclaimer futher reduced it size (90mm)and stacker makes it pile and futher transferred through belt conveyor to Hoppers </li></ul>
  • 11.  
  • 12. Row mill <ul><li>It is mixing the raw material using conveyor belt & weigh feeder. </li></ul><ul><li>It is vertical roller mill equipped with magnetic separator & metal detector just before it. </li></ul><ul><li>Water spray inside it to avoid much friction and abrasion. </li></ul>
  • 13.  
  • 14. Row Mill have following part <ul><li>Roller & table. </li></ul><ul><li>Air hydraulic unit (Nitrogen). </li></ul><ul><li>Lubricant unit . </li></ul><ul><li>Gas chamber. </li></ul><ul><li>Magnetic separator </li></ul><ul><li>Metal detector </li></ul><ul><li>Blending silo </li></ul><ul><li>Bag house </li></ul>
  • 15. Kiln Mill <ul><li>It has two part ,Pre-heater & Rotary kiln. </li></ul><ul><li>PRE-HEATER:- </li></ul><ul><li>Per-calcinations(67%) :- </li></ul><ul><li>It also called per-heater. The Per-calcinations technology is introduced in 1978 for reduced the length of kiln &to large energy was also save, in considerable amount. </li></ul>
  • 16. <ul><li>KILN: </li></ul><ul><li>kiln is heart of cement industry convert The per-calcinations raw mix into the clinker. </li></ul><ul><li>Kiln derived into three zone: </li></ul><ul><li>Calcinations zone </li></ul><ul><li>Burning zone + coal entering </li></ul><ul><li>Cooling </li></ul>

  • 19. Cement Mill <ul><li>Clinker from silo is comes into hopper from where it goes to weigh feeder .simultaneously gypsum is also added though another weigh feeder. Both material is proportionally mixed and fed into cement mill. </li></ul><ul><li>The cement mill is a horizontal mill and another names is ball mill consist as grinding in the mill are ball. It consist of tow parts, initially the grinding is done by big ball and second section grinding is done by small ball which result in fine to be checked by .for this tons per hour of martial passed to the cement mill . </li></ul>
  • 20.  
  • 21. Packing Plant <ul><li>Cement from the cement silo comes into automatic rotary packer. There are four packer, three are 12 spouts & one 16 spouts. </li></ul><ul><li>worker put empty bags to the hook of packers 50 kg cement is automatically filled in this packs as the packer pack .The weight of cement is continuously displayed and a weigh becomes 50kg.the pack get sealed & transferred to conveyor belt. These packs are loaded automatically in trucks & in wagon (PLC programming over there ) </li></ul>
  • 22. Why we use 4-20mA current loop <ul><li>With 0-20 or 0-10 mA you can’t distinguish between min field value and connection break .Witth 4-20 mA ,internal circuit can distinguish between connection break of min value. Normally when the value is min the transmitter will give you 4 mA while in case of connection breakage it will give you 0 mA. </li></ul>
  • 23. Instrumentation in cement plant <ul><li>Bnani cement Ltd. is an automated plant. In any automated plant, instrumentation plays a very important role. All the parameters are to be measured at the site and have to be measured transmitted to control room where their values are checked and controlled (CCR). </li></ul>
  • 24. Measured- Parameters <ul><li>Temperature :-RTD, Thermocouple, thermometer, pyrometer etc. </li></ul><ul><li>Level :-Ultrasonic level sensor, phola-phone, RADAR etc. </li></ul>
  • 25. <ul><li>Proximity switches </li></ul><ul><li>Limit switch </li></ul><ul><li>ZSS (Zero speed switch) </li></ul><ul><li>Pull cord switch </li></ul><ul><li>Separator </li></ul><ul><li>Metal detector </li></ul><ul><li>Magnetic separator </li></ul><ul><li>Control valve: </li></ul><ul><li>Solenoid valve </li></ul><ul><li>water spray valve. </li></ul>
  • 26. Weigh feeder <ul><li>WEIGHING SYSTEMS ARE ESSENTIAL NEED OF ANY PROCESS INDYSTRY WHERE ROW/ FINE MATERIAL HANDLING REQUIRED WITH AQURACY. </li></ul><ul><li>MOST COMMON WEIGHING SYSTEMS THAT ARE USED IN PROCESS PLANTS ARE- </li></ul><ul><li>WEIGH FEEDER </li></ul><ul><li>BELT WEIGHER </li></ul><ul><li>SOLID FLOW FEEDER/ METER ETC . </li></ul>
  • 27. BLOCK DIAGRAM: W/F
  • 28. PRINCIPLE OF OPERATION <ul><li>LOAD (Q) PER UNIT LENGTH MULTIPLIED BY THE SPEED (I) OF THE BELT / APPRON GIVES THE RATE OF TRANSFER IN UNIT TIME. THIS RATE (I) IS INTEGRATED W.R.T. TIME GIVES THE QUANTITY CONVEYED . </li></ul><ul><li>I= Q . V . 3600 </li></ul><ul><li>WHERE I in Kg/hr </li></ul><ul><li>Q in Kg/m </li></ul><ul><li>V in m/s </li></ul>
  • 29. COMPONENTS OF WEIGH SYSTEM <ul><li>WEIGH FEEDER SYSTEM CONSIST OF : 1. LOAD CELL 2. TACHO LOAD CELL </li></ul><ul><li>STRAIN GAUGE BASED LOAD CELL IS EMPLOYED TO SENSE LOAD ACTING ON IT. </li></ul><ul><li>LOAD SENSING PRIMARY COLUMN IS MADE OF CORROSION RESISTANT SUPER TOUGH STEEL ALLOY OF HIGH TENSILE STRENGTH AND THE STRESS DEVELOPED DUE TO THE LOAD IS MEASURED WITH FOUR PRECISION FOIL TYPE STRAIN GAUGES BONDED TO THE SENSING ELEMENT. </li></ul><ul><li>THE STRAIN GAUGE RESISTORS ARE CONNECTED TO FORM A BALANCED WHEATSTONE BRIDGE NETWORK </li></ul>
  • 30. <ul><li>TACHOGENERATOR </li></ul><ul><li>THE SPEED OF WEIGH FEEDER IS SENSED BY A TACHOGENERATOR, COUPLED TO THE SHAFT OF THE DRIVEN PULLY OF THE BELT WHICH ELEMINATES THE SMALL ERRORS CAUSED DUE TO BELT SLIP. </li></ul><ul><li>DIGITAL TACHOMETER GIVES PULSES PROPORTIONAL TO ITS SPEED OF ROTATION IS COUPLED TO DRIVEN PULLY. </li></ul>
  • 31. Pollution control <ul><li>BAG HOUSE </li></ul><ul><li>JPF </li></ul><ul><li>ESP </li></ul>
  • 32. DCS <ul><li>Distributed control system (DCS) is widely used for automation in modern industry since a process industry is usually installed in wide area and has a large number of machine and process sections, hence to operate and control all the machinery suitable from one place i.e CCR ,one may install DCS. It has the capability to interface with external party software . </li></ul><ul><li>The DCS system used in industry .I took my training has a supplied by the company ABB, hence the system is also know as ABB master. </li></ul>
