[0002] Most of the current concrete is not mixed and stirred at the construction site, but transported to the construction site after mixing at a large concrete mixing station. To mix concrete, the raw materials and water must first be poured into a mixing tank with rotating stirring blades. After the raw materials are mixed in the mixing tank, they are discharged from the discharge pipe to form concrete that can be used for construction.
