The large volume of the tank not only affects the cost of purchasing a car, but also affects the performance of the vehicle. The lower the driving coefficient, the heavier the tank_ The higher the heart, the poorer the stability of the vehicle. Therefore, car owners should choose the appropriate Concrete mixer according to the working conditions, economic benefits, performance and other factors of the mixer.

混凝土搅拌车容积不能简单的认为就是罐体的容积，要有明确的三个概念区分：

First of all, the volume of Concrete mixer cannot be simply considered as the volume of tank body, and three concepts should be clearly distinguished:

搅拌车几何容积：搅拌桶内实际的几何容积，是指搅拌罐设，用数学方法计算出来的几何容积。

Mixing truck geometric volume: The actual geometric volume inside the mixing drum refers to the geometric volume calculated using mathematical methods during the design of the mixing tank.

搅拌动容积：搅拌车能够运输的预拌混凝土量（以捣实后的体积计）。可以看成搅拌车到达工程现场所能够卸下的混凝土方量预拌混凝土容量按2400kg/m3计算。

Mixing capacity: The amount of pre mixed concrete that can be transported by the mixer truck (measured by the volume after compaction). It can be seen that the volume of concrete that can be unloaded by the mixer truck upon arrival at the construction site is calculated based on the capacity of 2400kg/m3 of pre mixed concrete.

搅拌容积：搅拌车置于水平位置，搅拌桶能容纳较大的未经搅拌的混凝土物料（包括水），并能搅拌出运混凝土的量（以捣实后的体积计）。

Mixing volume: The mixer truck is placed in a horizontal position, and the mixing bucket can accommodate a large amount of unmixed concrete material (including water), and can mix and transport the amount of concrete (measured by the volume after compaction).

三者的关系应该是：搅拌车几何容积＞搅拌容积＞搅拌动容积，用户经常所说的容积应该是指搅动容积，所以在现购搅拌车时，要注意区分问清车辆的搅拌容积。

The relationship between the three should be: geometric volume of the mixing truck>mixing volume>stirring volume. The volume often referred to by users should refer to the stirring volume. Therefore, when purchasing a mixing truck, it is important to distinguish the mixing volume of the vehicle.
