Most of the existing raw material mixing devices are stirring tanks. Due to the influence of gravity, most of the raw materials are deposited at the bottom of the stirring tank during mixing. The existing stirring tank only relies on the main stirring paddle for stirring and mixing, and its mixing effect is not good; moreover, both the aluminum source and the calcium source are powdery solids and have the property of being easy to agglomerate and cake. The existing stirring tank has a poor crushing effect on the deposited and caked raw materials, resulting in uneven chemical composition of the produced calcium aluminate binder, poor particle dispersibility, poor product performance, and poor use effect.
