Product plan: Mainly P.052.5 and P.042.5 Ordinary Portland Cement. The packaged cement accounts for 30%, and bulk cement accounts for 70%. Construction scale: The Luang Prabang 3200t/d cement clinker production line is an energy-saving and capacity-increasing retrofit project. The cement clinker output increases from 700t/d to 3200t/d. The annual output of cement clinker is 992,000 tons, and the annual cement output is 1.1 million tons. The scope of the retrofit includes limestone crushing, raw material batching, raw material grinding and exhaust gas treatment, raw material homogenization silo, kiln tail, kiln middle, kiln head, coal powder preparation, cement grinding, cement packaging, and related auxiliary workshop system retrofit.
Production capacity: Before retrofit: 700t/d, After retrofit: 3600t/d
Standard coal consumption: Before retrofit: 160kg/t, After retrofit: ≤102kg/t
Clinker electricity consumption: Before retrofit: 89(kw·t/h), After retrofit: <55(kw·t/h)
Preheater: Before retrofit: Fifth-level preheater from a certain institute in Yunnan, After retrofit: LVRF5 new preheater, separating the preheater from the decomposition furnace and fully utilizing the original preheater frame to install a new decomposition furnace.
Rotary kiln: Before retrofit: Φ2.8*42m, After retrofit: Φ4.2*48.5m
Grate cooler: Before retrofit: Third-generation grate cooler, After retrofit: Fourth-generation LSFC type pushing rod grate cooler
Raw material mill: Before retrofit: Central discharge ball mill, After retrofit: Roller press
