The production method is dry process. A rotary kiln(φ3.5×54m) production line with five-stage cyclone pre-heater and decomposition furnace will be adopted.
1.2生產能力及工廠規模Production scale and capacity
燒成系統生產能力為日產熟料1500噸，摻加石膏后工廠年產硅酸鹽水泥500000噸。
The production capacity is 1500t/d for clinker, while 500,000t/a for Portland cement when mixed with gypsum.
1.3 水泥品種 Cement types
本技術和設備可生產符合中國水泥標準GB175-1999中的硅酸鹽水泥,其強度為32.5MP、42.5MP，可根據市場需要進行調節。
The technology and equipment adopted can produce 32.5MP and 42.5MP types of cement in accordance with Chinese Standard GB175-1999. They can be adjusted according to market demand.
2. 工藝設計特點Main technical characteristics
2.1 為保證系統運轉率，提高產品產、質量，設計中大量選用了具有二十世紀九十年代先進水平的新設備、新工藝，以提高生產線的裝備水平，確保設計指標的實現。如新型五級旋風預熱預分解系統、高效空氣梁篦冷機，節能型多通道噴煤管，戴維森高溫風機，魯奇最新技術生產的電收塵（BS930）等，輸送設備采用了耐用、節電的板鏈提升機、鏈式輸送機，將使本工程的裝備在同規模生產線中處于領先水平。
This production line adopts advanced technology and equipment in 1990s to raise technical level and to ensure design indexes. New five-stage cyclone pre-heater system, high efficiency air girder grate cooler, multi-passage pulverized coal burner, Davison heat temperature fan, Luqi BS930 electrical dust collector, as well as chain-board elevator, chain conveyor adopted in this production line can ensure that the technology is advanced compared to other production lines with the same scale.
2.2 在保證生產線的完整性、生產的連續性和可靠性的前提下，力求簡化生產工藝流程，以便于生產管理，減少生產事故點，降低投資。
If it has not bad influences on completeness，continuity and reliability, process procedures will be simplified to enhance production management, reduce troubles and lower investment.
2.3 工藝布置上，簡化設備廠房，減少建筑面積 Simplifying houses for equipment to decrease building area
庫頂露天布置；高溫風機露天布置；帶式輸送機通廊不設屋頂，用玻璃鋼防雨罩防雨；取消提升機樓；收塵器露天放置。
Top of silos are without covers, heat temperature fan and dust collectors are open arranged and glass fiber rainproof covers instead of roofs will be set for belt conveyor passages. There will be no building for bucket elevator.
對各種原料、半成品和成品，在滿足正常生產要求的前提下，合理減少儲存期，并盡量采用堆棚儲存。土建費用大幅度降低。
If it has not bad influences on normal production, by properly reducing storage periods for all raw materials, semi-product and finished product and adopting shed to store those materials and products, civil engineering costs will be greatly reduced.
改進窯尾工藝布置，窯尾預熱器塔架設計為鋼結構，既可加快施工安裝進度，節省投資，又可美化建筑。
Frame for pre-heater at kiln inlet will adopt steel structure to save investment, accelerate erection speed and beautify building.
2.4 充分考慮節能、降耗，生料入窯使用節能型的板鏈式提升機和空氣輸送斜槽，提高了系統的運行可靠性，降低了輸送能耗。
Measures have been taken to save energy and reduce consumption. using chain-board elevator and air slides, reliability of the system is enhanced and conveying energy consumption is decreased.
