S厂2500t/d预分解窑系统熟料质量问题的技术诊断

Technical diagnoses of clinker quality problem of precalciner kiln system in 2500 t/d production line of S plant

2004年投运的S厂2500t/d生产线,其熟料3d强度低,大致在24.2MPa,28d强度仅在54.4MPa左右波动。分析了S厂原料的影响、装备状况的影响和系统软件、操作技能的影响等影响因素。判断出生料质量不均是熟料质量低的首要原因;其次是配料优化和操作优化的问题。S厂根据诊断结果开展一系列工作后,取得了较好的效果,3d强度已提高至27～28MPa。

t/d clinker production line of S plant is put into production in 2004, 3 d compress strength of the clinker was low about 24.2 MPa and the 28 d strengh fluctuated about 54.4 MPa. Several effect factors like material, equipment condition, system software and operation skill were analysed in this paper. And the inhomogenous quality of raw material was considered as the all-important factor of low comperss strength clinker, batching and operation optimization were the next. A series of work were carred out based on the diagnoses results, and the 3 d compress strength had improved to 27～28 MPa.
