According to the CCTV Finance Excavator Index, the operating rate of mixers will rank second for five months in 2025. As a core link in infrastructure construction such as earthwork and concrete pouring, its stable performance indicates that by 2025, China's residential construction, municipal pipeline network, industrial park supporting and other livelihood and industrial projects will steadily advance.
The purpose of a cement concrete mixer is to mechanically mix cement concrete. There are many types of mixers, and their classification methods and characteristics are as follows.
Classify by homework method
There are two types of homework: cyclic homework and continuous homework.
The three processes of feeding, mixing, and unloading in a cyclic operation are carried out at certain time intervals, that is, by mixing in portions.
Due to the accurate weighing of various materials used in mixing, the mixing quality is good. Most of them adopt this type of homework method.
The above three processes of continuous operation are carried out continuously in a longer cylinder. Although its productivity is higher than that of circular operation, the mixing quality is poor due to the difficulty in controlling the mixing ratio and mixing time of each material. Less usage.
