Oman Cement Company

Oman Cement Company Oman Cement Company (SAOG) was shaped in 1978. Rusayl Cement plant was finished in 1983 with a yearly coordinated concrete creation limit of 624,000 tons, of concrete. In 1999 clinkering limit extended to an aggregate of 1.2 million tons for every year. The subsequent creation line went ahead stream in mid 1998. By and by the organization is dealing with growing the limit of plant structure 1.26 MTS every year to 1.70 MTS every year by updating creation line No. 1 and No. 2. The organization offices are: 1-Computerized Manufacturing Oman concrete assembling process is completely automated. This stays away from significant risks in assembling and needs less labor. 2-Central Laboratory The Quality Control is bolstered by focal research center comprising of mechanical technology, X-beam spectrometers, laser molecule size analyzers and mechanized physical properties testing gear. 3-Quality Management System and Environmental Management System oman concrete Quality Management System is as per the Quality Assurance Procedures of ISO 9001 : 2000 accreditation. 4-Pollution Control. The Oman concrete organization produces numerous kinds of concrete which are: 1-Ordinary Portland Cement: It is type I Portland concrete. Its uses are strengthened solid structures, scaffolds and railroad structures. The normal compound pieces of this sort are: 55% (C3S), 19% (C2S), 10% (C3A), 7% (C4AF), 2.8% MgO, 2.9% (SO3), 1.0% Ignition misfortune, and 1.0% free CaO. 2-Sulfate Resistant Cement: It is type V, is utilized where sulfate opposition is significant. Its average compound piece is: 38% (C3S), 43% (C2S), 4% (C3A), 9% (C4AF), 1.9% MgO, 1.8% (SO3), 0.9% Ignition misfortune, and 0.8% free CaO. 3-Moderate sulfate safe: It is type II concrete. This kind of concrete can be utilized in structures of extensive mass, for example, huge wharfs, overwhelming projections, and substantial holding dividers. Its utilization will decrease temperature rise particularly when the solid is dependent upon blistering climate. Its run of the mill mixes arrangement is: 51% (C3S), 24% (C2S), 6% (C3A), 11% (C4AF), 2.9% MgO, 2.5% (SO3), 0.8% Ignition misfortune, and 1.0% free CaO. 4-Oil Well Cement Oil well concrete, utilized for oil wells grouting, typically produced using Portland concrete clinker or from mixed water powered concretes. It is utilized for solidifying work in the penetrating of oil wells where they are dependent upon high temperatures and weights. Its normal compound sythesis is: MgO: 6.0% SO3: 3.0% Loss On Ignition: 3.0% C3S: 48%-65% C3A: 3.0% Insoluble Residue: 0.75% C4AF+2C3A: 24% Creation techniques: There are four phases to deliver concrete that Oman concrete utilizing which are: 1-Preparation of the crude material at quarries 2-Heating and cooling to deliver clinker 3-Preparation of the concrete 4-Cement pressing Procedure depiction: 1-Preparation material at quarries The crude material contains of limestone (80% of crude material), silica, aluminate and iron mineral. The quarries situated around the Oman concrete plant. At quarries the crude materials are extricated with substantial types of gear. At that point the limestones are squashed with versatile smashers associated with long transport line to move them to capacity passing the auto lab to examination the examples with x-beam every two hours. After that the crude material are moved to repositories. At that point they are moved with transport line to the crude factory to pound the crude materials. At long last the pounding crude materials are moved to blend stores to get legitimate blend before took care of them to furnace. 2-Heating and cooling to create clinker The crude materials are moved to channel, where warmth trade is happened between these material and the raising hot gases from furnace, at that point the materials are isolated from the gases. After that the material moved to calciner where the limestone is changed over to calcium oxide, and afterward the calcined materials arefed to the oven where the temperature around 1400 c and afterward leave from furnace to get clinker. At that point the clinker leaves from oven to air to decrease its temperature to 100 c to be fit to be moved to solidify plant. Furnace process 3-Preparation of concrete The clinker that came out of the cooler will be shipped by the can anchor transport to the storehouse. The sack channel on the highest point of the storehouse is estimated for the taking care of by the container chain transport and warm air extension in the capacity. The clinker removed from the storehouse is moved by belt transports to the concrete proportioning. The gypsum is added to the clinker. At that point the proportioned materials are passed on by means of belt transport to solidify granulating. Materials ground by ball factory are shipped separator by can lift. The coarse particles isolated come back to ball factory for regrinding while the fine item is gathered by the sack channel behind the separator and afterward passed on to solidify storehouse with an air slide and can lift. Concrete storehouses is utilized to store the concrete. Concrete plant 4-Cement pressing The concrete from extraction frameworks under the concrete storehouse is conveyed to the support container via air slide and the basin lift and vibrating screen, before being taken care of into every packer. The packed away concrete can be stacked legitimately or put away in storage facility incidentally. Hardware and Equipments: No. Name work 1 Limestone Crusher utilized in stone quarry to squash limestone 2 Clay smasher utilized in stone quarry to pulverize earth 3 Limestone Stacker Used to move limestone to preblending store 4 Limestone reclaimer Used to take preblended blend from preblending store 5 Coal and iron metal Crusher Used to smash added substance materials 6 Coal and iron metal Stacker Used to move iron metal to transport line then to proportioning station 7 Coal iron metal reclaimer Used for recovering every added substance material and coal 8 Raw factory utilized for crude materials crushing and drying 9 Raw factory fan Used to change the plant channel temperature. 10 Preheater fan used to dry the crude materials 11 Preheater and precalciner Preheater utilized for preheating and fractional decarbonation, and precalciner for calcination 12 Rotary furnace used to raise crude materials to a high temperature 13 Grate cooler Used for extinguishing 14 Cement factory Used to crush concrete 15 Bag channel Used to gather dust 16 Coal factory Used for coal drying 17 Bulk loader for truck Used to stack the mass 18 Cement packer Used to pack concrete item Quality control framework: The quality control division in the Oman concrete organization work is to screen item quality in each phase of creation beginning with removing the limestone from the quarry till the phase of concrete factories, by taking examples and examination them. 1-The PC and x-beam investigation: The robotization lab comprises of robot, x-beam spectrometers, laser molecule size analyzer and electronic physical properties. The examples will be taken by a programmed sampler from a point between the crude plant and homogenizing storehouse and afterward shipped physically to the focal auto lab, where it will be semi-naturally arranged and sent to a X-Ray analyzer. The outcomes broke down will be sent to a proportioning PC. The PC will ascertain the proportion of crude materials and convey the set an incentive to steady feeder as per the substance pieces and crude supper module required. 2-Physical examination: To test the fineness, adequacy, setting time, quality, explicit gravity, warmth of hydration and misfortune on start of the concrete to accomplish the American particulars prerequisite. Upkeep method: The office capacities are: - Checking all apparatus and types of gear are work appropriately. - Scheduling and making arrangements for preventive support, prescient upkeep. Organizing with all divisions for every day issue. Arranging, organizing of preventive and breakdown exercises for accomplishing high plant accessibility to meet creation target. The technique that the Oman concrete follows if there should arise an occurrence of breakdown, preventive and shutdown upkeep are: 1. Breakdown upkeep If there should be an occurrence of any breakdown support in the creation office, they give data in regards to the breakdown to the upkeep office, and upkeep laborers are sent to the creation plant to fix machine disappointments. 2. Preventive upkeep here, a group of upkeep laborers is sent legitimately to the creation plants to look at whether there is any disappointment in the apparatus or not. 3. Shutdown support At the point when the plant is closed down the representatives in the creation office sent a letter to the support office and progressive advances are taken by upkeep office to comprehend the disappointments. The plant shutdown happens each half year in March and September. The way toward working and checking creation lines and machines immediately, so they can watch the disappointment and harm of the machines and types of gear to fix them or supplant them. Specialized administration The specialized administration duty is to oversee all the mechanical, electrical things and keep up the different supplies and everything that identified with support method, and this administration separated in numerous areas: a-The machine segment The obligation of this area is get ready crisis and arranging plan and do it to all the types of gear and report it to analyze the bizarre disappointment and fix it. Review the apparatus, check with drawings and details and amendment. It contacts with store segment to give the necessary new parts and furthermore contacts with different segments to keep up the types of gear at the workshop. At the workshop they fix the types of gear in crisis conditions, check the types of gear in the event that they work appropriately and routinely, takes care the types of gear and help to clean them. b) The machine activity area The duty of this area create the new parts, make a request outside the organization to get new parts, machine the machine parts the necessary the workshops. c) The quick machine support segment The duty of this area is to check and fix the creation lines. d) The electrical area The el
