伴随国家高速铁路和客运专线的快速建设,对混凝土的拌和以及搅拌设备的自动化程度要求越来越高,在实现混凝土自动化上料、搅拌和卸料的同时,对搅拌站的自动化称量也提出了更高要求。对于高性能、耐久性混凝土除要求有充分的搅拌外,还要求原材料有精确的配比。控制混凝土原材料称量精度,通常要做到以下几点: With the rapid construction of national high-speed railway and passenger dedicated line, the requirements on the degree of automation of concrete mixing and agitation equipment are getting higher and higher. In the meantime, the automatic weighing of the mixing station is also put forward while realizing the automatic feeding, mixing and discharging of concrete A higher requirement. For high performance, durable concrete in addition to requiring adequate mixing, but also requires accurate raw materials ratio. Control of concrete raw material weighing accuracy, usually to do the following:
