New Dry Process Cement Production Line (1000TPD)

1000tpd Dry Process Cement Production LineDescription of New Type Dry Process Cement Production Line: This new type dry process cement production line is a kind of process mainly used for small, medium and large-scale cement plants. Its preheater employs outside kiln precalciner. Capable of utilizing the waste heat from kiln inlet to decompose raw meal, this line is good at saving electricity and heat. Its closed production line makes it possible to reduce its ambient dust pollution to less than 50mg/Nm3. Besides, its capacity to make use waste heat makes it quite cost efficient for users.Here in Jiangsu Pengfei Group Co., Ltd, we offer one-stop service for you, including designing, building, suitable equipment providing, installing and debugging, technical serving, and overall contracting. And we have successfully finished the construction of cement production lines of 6000t/d, 5000t/d, 3000t/d, 2500t/d, 1500t/d, and 600t/d.Production Flow of New Type Dry Process Cement Production Line: 1. Crushing and Pre-homogenizing:Most of the raw materials, like limestone, clay, iron ores, and coal, should be crushed before their pre-homogenization. Limestone is the primary material in this line, and due to its large particle size and high hardness, its good crushing plays an important role in the whole line. Special stacking and reclaiming technology has been used in the pre-homogenizing process so that raw materials can be better primarily homogenized.2. Raw Meal Preparing:Since the raw meal grinding work takes up more than 30% labor force in the whole dry process cement production line, it is quite important to choose appropriate grinding equipment and technological process so that high-quality products can be obtained.3. Raw Meal Homogenizing:The raw meal homogenization is a key factor for stable clinker calcination.4. Preheating and Decomposing:The preheater is used to preheat as well as decompose raw meal. So the length of the rotary kiln is effectively shortened. And the raw meal can fully exchange heat with the hot gases from the kiln. Because of its rapid and high-efficiency heat transfer, the production efficiency and heat consumption of this production line are greatly improved.5. Clinker Calcining:After its preheating and pre-decomposing, the raw meal will be calcined in the rotary kiln, where the generated carbonate will be further decomposed. Meanwhile, a series of solid phase reactions will take place.6. Cement Grinding:As the last process, the cement grinding will consume a great deal of electricity. And in this process, special size granule cement will be obtained.7. Cement Packaging:The cement can be transported in bulk or in bags.Main equipment list DepartmentEquipment nameSpecificationQtyWeight(t)1:Preparation ofRaw MaterialshammerCrusher for limestoneCapacity: 150~220t/hFeed size: 1000mmProduct size: 95%≤25mm1 532 Limestone pre-blendingSide cantilever stackerDB250/14.5Material repose angle: 38°Capacity:300t/h 1 Bridge-type scraper reclaimerQG 120/22Capacity:120 t/h 1 3:Raw Meal Preparation Tube mill3.8*7.5mCapacity : 85t/hFeed size : ≤ 25mmFineness: ≤12~14% ( R 80mm)Product moisture: ≤1%Motor Power : ~1,400kW1   1180Mill fanCapacity : 200,000m3/hPressure :6,500PaMotor Power: 500kW1 1~18  ID fanCapacity : 280,000m3/hPressure : 7,500PaMotor Power: 800kW1 1~20  Bag filterCapacity : 280,000m3/hTemp. : 100ºC-mill on       200ºC-mill offOutlet dust content : ≤30mg/ Nm31~132FanCapacity: 280,000m3/hPressure: 2,800PaMotor Power: 250kW1 1~23    4:Clinker manufacturePreheater and precalcinerCapacity :1,200t/dCyclone :C1 :1-Φ4,950mmC2 :1-Φ4,950mmC3 :1-Φ4,950mmC4 :1-Φ5,200mmC5 :1-Φ5,200mmPrecalciner:Φ3,900×24,000mm1~250Rotary kilnΦ3.3×50mCapacity :1000t/dPiers :3Inclination: 4%Speed :0.4~4.2r/minMotor Power:190kW1    1320Tertiary air ductΦ1,800mm1 Clinker coolerCapacity : 1,200t/dCooling area : ~31m2Inlet temp.:1400ºCOutlet temp. : 65C+amb. temp.Motor Power:63kWClinker crusher 1   11 ~150Burner 1~3EP for coolerGas volume : 180,000m3/hInlet temp.: 250ºC(Max. 400ºC)Outlet dust content :
