Oman Cement Company

Oman cementum Company ( SAOG ) was create in 1978. Rusayl cement work was completed in 1983 with an one-year incorporate cement deed capacitor of 624,000 dozenss, of cement. In 1999 clinkering electrical capacity expanded to a sum of 1.2 million dozenss per twelvemonth. The 2nd turnout line came on watercourse in mid 1998. Pre movely the company is working on spread outing the capacity of works signifier 1.26 MTS per twelvemonth to 1.70 MTS per twelvemonth by upgrading production line no. 1 and No. 2.The company inst entirelyations are1- Computerized FabricationOman cement finesse procedure is to the full computerized.This avoids major jeopardies in fabrication and needs less work force.2- Central LaboratoryThe character reference Control is supported by cardinal number research lab consisting of robotics, X-ray spectrometers, optical maser atom size analysers and computerized tangible belongingss proving equipment.3- Quality Management organization and Environmental Man agement Systemoman cement Quality Management System is in conformity with the Quality Assurance Procedures of ISO 9001 2000 enfranchisement.4- Pollution Control.The Oman cement company produces many pillowcases of cement which are1- Ordinary Portland cementIt is type I Portland cement. Its utilizations are strengthened concrete edifices, Bridgess and railroad constructions. The normal compound composings of this type are55 % ( C3S ) , 19 % ( C2S ) , 10 % ( C3A ) , 7 % ( C4AF ) , 2.8 % MgO, 2.9 % ( SO3 ) , 1.0 % sacking loss, and 1.0 % free CaO.2- Sulphate Resistant CementIt is type V, is utilize where sulfate opposition is of import. Its typical compound composing is38 % ( C3S ) , 43 % ( C2S ) , 4 % ( C3A ) , 9 % ( C4AF ) , 1.9 % MgO, 1.8 % ( SO3 ) , 0.9 % Ignition loss, and 0.8 % free CaO.3- Moderate sulfate resistantIt is type II cement. This type of cement can be utilise in constructions of considerable mass, such as big wharfs, heavy abutments, and heavy retaining walls. I ts usage consecrate up stakes cut down temperature rise particularly when the concrete is capable to hot conditions. Its typical compounds composing is51 % ( C3S ) , 24 % ( C2S ) , 6 % ( C3A ) , 11 % ( C4AF ) , 2.9 % MgO, 2.5 % ( SO3 ) , 0.8 % Ignition loss, and 1.0 % free CaO.4- Oil Well CementOil proper cement, utilize for oil Wellss grouting, normally made from Portland cement cinder or from blended hydraulic cements. It is used for cementing work in the boring of oil Wellss where they are capable to heights temperatures and force per unit areas. Its typical compound composing isMgO 6.0 % SO3 3.0 % Loss On Ignition 3.0 % C3S 48 % -65 % C3A 3.0 % Insoluble Residue 0.75 % C4AF+2C3A 24 % achievement methodsThere are four phases to bring forth cement that Oman cement utilizing which are1- Preparation of the innate(p) stuff at preies2- H ingest and chilling to bring forth cinder3- Preparation of the cement4- Cement waddingProcedure description1- Preparation stuff at preiesThe c ongenital stuff contains of limestone ( 80 % of rude(a) stuff ) , silica, aluminate and Fe ore. The preies located around the Oman cement works. At preies the natural stuffs are extracted with heavy equipments. therefore the limestones are crushed with nomadic crushers connected with long conveyor belt to transport them to storage go throughing the car lab to analysis the samples with x-ray each two hours. After that the natural stuff are go to reservoirs. wherefore they are locomote with conveyer belt to the altogether mill to crunch the natural stuffs. Finally the crunching natural stuffs are moved to miscellany reservoirs to acquire proper mixture before feed them to kiln.2- Heating and chilling to bring forth cinderThe natural stuffs are moved to impart, where heat re-sentencing is occurred amid these stuff and the raising hot gases from kiln, so the stuffs are separated from the gases. After that the stuff moved to calciner where the limestone is converted to calcium oxide, and so the calcined stuffs arefed to the kiln where the temperature about 1400 point in time Celsius and so go forth from kiln to acquire cinder. Then the cinder leaves from kiln to childs play to cut down its temperature to 100 degree Celsiuss to be ready to be moved to cement factory.Kiln procedure3- Preparation of cementThe cinder that came out of the ice chest allow for be transported by the pail concatenation conveyer to the silo. The bag filter on the top of the silo is sized for the eating by the pail concatenation conveyer and thermic air enlargement in the storage. The cinder extracted from the silo is transported by belt conveyers to the cement proportioning. The gypsum is added to the cinder. Then the proportioned stuffs are conveyed via belt conveyer to cement crunching. Materials land by orchis factory are transported extractor by pail lift. The harsh atoms separated return to ball factory for regrinding while the all right trade in is collected by the bag filter behind the centrifuge and so conveyed to cement silo with an air slide and pail lift. Cement silos is used to hive away the cement.Cement factory4-Cement waddingThe cement from extraction systems under the cement silo is delivered to the buffer bin by air slide and the pail lift and vibrating screen, before being fed into each bagger. The bagged cement can be loaded refined or stored in depot temporarily.Machinery and EquipmentsNo. Name mathematical function1 Limestone Crusher used in rock feed to oppress limestone2 Clay crusher used in rock prey to oppress clay3 Limestone Stacker Used to travel limestone to preblending reserve4 Limestone reclaimer Used to take preblended mixture from preblending reserve5 Coal and Fe ore Crusher Used to oppress linear stuffs6 Coal and Fe ore Stacker Used to travel Fe ore to conveyor belt so to proportioning station7 Coal & A Fe ore reclaimer Used for repossessing all linear stuffs and coal8 Raw factory used for natural stuffs crunching a nd drying9 Raw factory buffer Used to set the factory recess temperature.10 Preheater fan used to dry the natural stuffs11 Preheater and precalciner Preheater used for preheating and partial decarbonation, and precalciner for calcination12 Rotary kiln used to arouse natural stuffs to a high temperature13 Grate ice chest Used for slaking14 Cement factory Used to crunch cement15 Bag filter Used to roll up dust16 Coal factory Used for coal drying17 Bulk stevedore for motortruck Used to lade the majority18 Cement bagger Used to pack cement merchandiseQuality control systemThe quality control section in the Oman cement company map is to supervise merchandise quality in every phase of production get downing with pull outing the limestone from the prey till the phase of cement Millss, by taking samples and analysis them.1- The computing apparatus and x-ray analysisThe mechanization lab consists of automaton, x-ray spectrometers, optical maser atom size analyser and computerized physica l belongingss.The samples will be taken by an automatic sampling station from a point between the altogether factory and homogenising silo and so transported manually to the cardinal car lab, where it will be semi-automatically prepared and sent to an X-Ray analyser. The consequences analyzed will be sent to a proportioning computing machine. The computing machine will cipher the ratio of natural stuffs and direct out the set value to constant feeder harmonizing to the chemical composings and natural repast faculty required.2- Physical analysisTo prove the choiceness, soundness, puting clip, strength, specific gravitation, heat of hydration and loss on ignition of the cement to accomplish the American specifications demand.Care processThe section maps are-Checking all machinery and equipments are work decently.-Scheduling and be aftering for preventative fear, prognostic tuition. Coordinating with all sections for day-to-day job.
