一、概述在进行湿式喷浆技术攻关试验过程中,开始一年多我们采用风动罐武喷射机喷射湿砼。该机型罐内没有定量给料装置,完全依靠风力吹动自由落料,随机性很大。喂入管道的物料时多时少、时断时续,而且料团直径大,有时形成一个较长的料柱,不能浮 First, an overview In the process of wetting shotcrete technology research, the beginning of more than a year we use pneumatic cans jet jet wet concrete. The model tank does not have a quantitative feeding device, completely depends on the wind blowing freely blanking, randomness. Feeding the pipeline material from time to time less, intermittent, and the diameter of the dough, and sometimes form a longer column, can not float
