Preparation method of superfine mineral admixture for steam-cured concrete
The invention discloses a preparation method of a superfine mineral admixture for steam-cured concrete, which comprises the following steps: preparing powder raw materials according to a certain mass ratio, then adding a grinding aid additive, then transferring into a grinding device, setting grinding time, and after the grinding time is reached, taking out of the grinding device to obtain the superfine mineral admixture. According to the invention, the small ball mills are connected in series to simulate the bin dividing structure of the large tube mill for the first time, the ball forging type, grading, loading capacity and powder particle size in each ball mill are adjusted for matching setting, the grinding effect of each stage of ball forging is fully exerted, and the grinding efficiency of each stage of ball mill is ensured.
本发明公开了一种蒸养混凝土用超细矿物掺合料的制备方法，将粉体原材料按照一定质量比进行配置，然后加入助磨添加剂，随后转入粉磨装置，设定粉磨时间，达到粉磨时间后，出磨得到超细矿物掺合料。本发明首次使用小型球磨机串联模拟大型管磨的分仓结构，同时调整各球磨机内的球锻类型、级配、装载量和粉体颗粒粒径进行匹配设定，充分发挥各级配球锻的粉磨效果，保证各级球磨机的粉磨效率。
