This project used anthracite from Vietnam as fuel, offline fluidization calciner was adopted in burning system, preheater was six-stage as 4-2-2-2-1-1, fifth stage and sixth stage are overlap fluid, outlet temperature at C1 was lower than 300℃.
Project duration was 28 months, all test targets were achieved the contract requirements, now the clinker production capacity is over 6100t/d, cement quality was the best in Vietnam, and the project selling price is higher than other brand.
Meanwhile, replanning the raw material treatment system,combined the new line with existing line, easy to production and management.
Main equipment of this project were manufactured by China, with high quality and low price, saved the investment of the Owner.
