Cleaning concrete mixing drum and material inlet and outlet:

由于混凝土会在短时间内凝固成硬块，且对钢材和油漆有一定的腐蚀性，所以每次使用混凝土贮罐后，洗净粘附在混凝土贮罐及进出料口上的混凝土是每日维护必须认真进行的工作。

As the concrete will solidify into hard blocks in a short period of time, and has certain corrosiveness to steel and paint, it is necessary to clean the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank.
