16 m³ concrete mixer truck is a kind of heavy machinery and equipment widely used in construction, road construction and other fields, with high mixing efficiency, strong bearing capacity, easy operation, energy saving and environmental protection. As an indispensable and important equipment for modern construction projects, its efficiency and professionalism play a key role in urban construction. The working principle of the concrete mixer is to agitate the concrete through the spiral blades inside the mixing cylinder. During transportation, the mixing drum rotates forward at a low speed to maintain the mixing and fluidity of the concrete and prevent the concrete from being stratified or solidified during transportation. When arriving at the construction site, the mixing drum is reversed and the concrete is discharged through the discharge port.
