On December 4, 2018, the Huzhou Huaikan Southern Cement Co., Ltd. Phase I 5000t/d cooler revamp project, undertaken by Nanjing Kaisen Equipment Division, successfully passed the assessment and acceptance, with all performance indicators meeting the contractual agreements.
Due to fluctuations in raw materials for this production line, there was a significant amount of fly ash material from the kiln. Therefore, for the first time in the modification plan, a renovation approach combining a first-stage grate cooler (third-generation machine) with a second-stage grate cooler (fourth-generation machine) was adopted. The overall renovation period was short, costs were low, and the modified cooler has strong adaptability to materials without affecting the original clinker heat consumption. The ash hopper of the first-stage third-generation grate cooler can effectively remove part of the fly ash, avoiding the issue of large amounts of fly ash returning to the kiln if only a fourth-generation machine were used. After the clinker is crushed by the high-temperature roller crusher in the middle section, it undergoes further cooling by the second-stage fourth-generation grate cooler. The clinker temperature exiting the cooler has significantly decreased compared to before the renovation, and the steam production from waste heat power generation has also increased. After nearly 8 months of operation, the owner has gradually developed an operating method suitable for the renovated cooler. Currently, all assessment indicators meet contract requirements, and the assessment and acceptance certificate has been successfully obtained.
This technical revamp project provided new ideas for cooler renovations, and also accumulated a wealth of experience during the commissioning process, which has strong guiding significance for future cooler modifications.
