Ready-mixed concrete. In the concrete mixing station, the well-mixed homogeneous concrete is completely mixed; stirring capacity: the large volume of the ready-mixed concrete that can be transported by the truck after tamping, in m3. The volume of ready-mixed concrete is calculated as 2400kg/m3; feeding rate: the volume of ready-mixed concrete that enters the mixing drum of the transport truck from the mixing station (or batching station) per minute on average. Unit m3/min; discharge speed: the mixing drum rotates at the specified discharge speed, and the volume of concrete discharged from the transport truck every minute after tamping. Unit m3/min; discharge residual rate: the ratio of the mass of concrete remaining in the mixing drum of the transport truck to the mass of concrete with agitating capacity after discharge, expressed as a percentage.

In modern road construction and large-scale construction projects, in order to ensure the quality of concrete, improve work efficiency, and reduce environmental pollution, special concrete mixing plants (stations) are often set up to produce concrete with special equipment such as concrete mixing buildings in the plant; Unload the truck and send it to the construction site for direct pouring. However, if the transportation distance and transportation time of the concrete are a little longer, the cement will precipitate and separate from the water, destroying the uniformity of the concrete; at the same time, the cement deposited on the bottom of the carriage is difficult to remove, which increases cargo damage and reduces dump trucks. The actual shipping quality. The automatic concrete loading mixer overcomes this shortcoming of using ordinary dump trucks to transport concrete and ensures the quality of concrete pouring.

The concrete automatic loading mixer is a special vehicle that continuously mixes the loaded concrete slowly during the transportation process or on the construction site. Therefore, it is also called a concrete mixer truck.
