目前,较具规模的砼构件厂均使用砼集中搅拌装置。一般装备3～4台具有自动上料,定量加水的砼搅拌机,采用电子秤进行称量控制,搅拌时间由人工掌握。这种砼搅拌方式较之分散式搅拌具有砼配合比准确;生产效率较高;能耗较低;并可使用散装水泥的特点。这种集中砼搅拌站的效率高低以及砼的质量,往往取决于操作工人的技术熟练程度与责任心。因此,一般来说,砼的质量以及技术经济指标均存在一定的波动性。为了提高砼质量的稳定性
At present, the large-scale smashed component plants use smashing centralized stirring devices. The general equipment is equipped with 3-4 mixers with automatic feeding and quantitative water addition. The electronic scales are used for weighing control, and the mixing time is controlled manually. The ramming stirring method has the advantages of accurate mixing ratio of the hydrazine as compared with the decentralized stirring; the production efficiency is higher; the energy consumption is lower; and the characteristics of the bulk cement can be used. The efficiency of this centralized mixing plant and the quality of the crucible often depend on the skill and responsibility of the operators. Therefore, in general, there is a certain degree of volatility in the quality of helium and technical and economic indicators. In order to improve the stability of the crucible quality
