Large tank volume not only affects the cost of car purchase, but also affects the vehicle performance. The driving safety coefficient is low. The larger the tank body is, the higher the center of gravity is, and the vehicle stability is poor. Therefore, the car owners should choose the appropriate concrete mixer truck according to the working conditions, environment, economic benefits, performance, safety and other factors.
First of all, the volume of concrete mixer truck can not be simply considered as the volume of tank, but should be distinguished by three clear concepts
Geometric volume of mixer: the actual geometric volume in the mixing drum, which refers to the geometric volume calculated by mathematical method during the design of mixing tank.
Mixing dynamic volume: the amount of ready mixed concrete that can be transported by the mixer truck (based on the volume after tamping). It can be regarded as the concrete volume that the mixer truck can unload when it arrives at the project site. The ready mixed concrete capacity is calculated as 2400KG / m3.
Mixing volume: when the mixer truck is placed in a horizontal position, the mixing bucket can hold the largest amount of concrete materials (including water) that have not been mixed, and can mix the volume transported to the concrete (based on the volume after tamping).
The relationship between the three should be: the geometric volume of the mixer truck > the mixing volume > the stirring volume. The volume often referred to by the user should refer to the stirring volume. Therefore, when purchasing the mixer truck, we should pay attention to distinguish the mixing volume of the vehicle.
