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 taking a shot at extending the limit of plant structure 1.26 MTS every year to 1.70 MTS every year by overhauling creation line No. 1 and No. 2. The organization offices are: 1-Computerized Manufacturing Oman concrete assembling process is completely electronic. This stays away from significant dangers in assembling and needs less labor. 2-Central Laboratory The Quality Control is upheld by focal research facility comprising of mechanical technology, X-beam spectrometers, laser molecule size analyzers and mechanized physical properties testing hardware. 3-Quality Management System and Environmental Management System oman concrete Quality Management System is as per the Quality Assurance Procedures of ISO 9001 : 2000 affirmation. 4-Pollution Control. The Oman concrete organization produces numerous sorts of concrete which are: 1-Ordinary Portland Cement: It is type I Portland concrete. Its uses are fortified solid structures, scaffolds and railroad structures. The run of the mill compound structures 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 obstruction is significant. Its run of the mill compound organization 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 sort of concrete can be utilized in structures of impressive mass, for example, huge wharfs, overwhelming projections, and substantial holding dividers. Its utilization will lessen temperature rise particularly when the solid is dependent upon blistering climate. Its run of the mill mixes piece 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, normally 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 run of the mill compound organization 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 strategies: There are four phases to create concrete that Oman concrete utilizing which are: 1-Preparation of the crude material at quarries 2-Heating and cooling to create clinker 3-Preparation of the concrete 4-Cement pressing Procedure portrayal: 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 removed 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 stores. At that point they are moved with transport line to the crude plant to pound the crude materials. At last the pounding crude materials are moved to blend repositories to get appropriate blend before took care of them to furnace. 2-Heating and cooling to deliver clinker The crude materials are moved to channel, where warmth trade is happened between these material and the raising hot gases from oven, 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 diminish its temperature to 100 c to be fit to be moved to solidify factory. 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 pack channel on the highest point of the storehouse is measured for the taking care of by the container chain transport and warm air extension in the capacity. The clinker removed from the storehouse is shipped 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 crushing. Materials ground by ball plant are moved separator by basin lift. The coarse particles isolated come back to ball plant 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 sacked 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 squash mud 3 Limestone Stacker Used to move limestone to preblending reserve 4 Limestone reclaimer Used to take preblended blend from preblending reserve 5 Coal and iron mineral Crusher Used to pound added substance materials 6 Coal and iron mineral Stacker Used to move iron metal to transport line then to proportioning station 7 Coal iron mineral reclaimer Used for recovering every single added substance material and coal 8 Raw plant utilized for crude materials pounding and drying 9 Raw plant fan Used to alter the factory channel temperature. 10 Preheater fan used to dry the crude materials 11 Preheater and precalciner Preheater utilized for preheating and halfway decarbonation, and precalciner for calcination 12 Rotary oven used to raise crude materials to a high temperature 13 Grate cooler Used for extinguishing 14 Cement plant Used to pound concrete 15 Bag channel Used to gather dust 16 Coal plant 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 separating the limestone from the quarry till the phase of concrete factories, by taking examples and investigation 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 moved physically to the focal auto lab, where it will be semi-consequently 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 consistent feeder as per the concoction organizations 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 determinations prerequisite. Upkeep method: The office capacities are: - Checking all apparatus and types of gear are work appropriately. - Scheduling and anticipating preventive upkeep, prescient support. Organizing with all offices for day by day issue. Arranging, organizing of preventive and breakdown exercises for accomplishing high plant accessibility to meet creation target. The method that the Oman concrete follows in the event of breakdown, preventive and shutdown upkeep are: 1. Breakdown upkeep In the event of any breakdown upkeep in the creation office, they give data with respect to the breakdown to the support office, and upkeep laborers are sent to the creation plant to fix machine disappointments. 2. Preventive support here, a group of support laborers is sent straightforwardly 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 division sent a letter to the upkeep office and progressive advances are taken by support office to explain the disappointments. The plant shutdown happens each half year in March and September. The way toward working and observing creation lines and machines in a split second, 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 regulate all the mechanical, electrical things and keep up the different types of gear and everything that identified with support method, and this administration separated in numerous segments: a-The machine segment The obligation of this area is get ready crisis and arranging plan and do it to all the supplies and report it to analyze the bizarre disappointment and fix it. Assess the apparatus, check with drawings and particulars and amendment. It contacts with store segment to give the necessary new parts and furthermore contacts with different areas to keep up the supplies 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 supplies 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 prompt machine support segment The obligation of this area is to check and fix the creation lines. d) The electrical segment The el
