摘　　要：倮打塘砂石系统采用石灰岩人工料源,生产混凝土用砂石骨料。为控制成品骨料含泥量,系统采用了一种剔除含泥量大的小粒径料并辅以水洗的新工艺方式,解决了常规完全水洗方式带来的诸多问题。但由于这是一种新的尝试,其优越性还需要工程实践不断检验、探索。the Guodatang sand and aggregate processing system applies the artificial source of limestone to produce aggregates for concrete production. To control the sediment content in the finished aggregate, one new technology, which features elimination of small-grain-size aggregates with high sediment content and washing aggregates secondarily, is provided to the processing system, avoiding issues resulted from the conventional and complete aggregate-washing method. The advantages of this new method need to be proved and explored contin- uously in engineering practice.
