Application of concrete mixing plant
Concrete mixing plant is a combination of multiple equipment used to produce concrete professional machinery. Excellent concrete mixing plant productivity is not only high, but also to ensure the quality of concrete and save cement. It is often used in large quantities of concrete, long duration, large concentration of large, medium-sized water conservancy, electricity, bridges and other projects.
With the development of municipal construction, the use of concentrated mixing, to provide concrete mixing station has great advantages, which has been rapid development, and to promote the construction of concrete pumping, to achieve mixing, transportation, pouring machinery to create conditions for joint operations.
So, how to choose the right concrete mixing plant?
Performance of concrete for construction
Thus choose what kind of mixing host. Such as water conservancy projects must be used to force the mixing console. In addition, should also be based on the type of concrete can be mixed with optional ingredients and storage silos.
Construction of concrete task and its duration
Use these two parameters to choose how much the mixing station. If the coefficient is K, the specifications of the mixing station X = M / (T * H * K) shall be used, where K is 0.7 - and the number of days for the concrete is M; 0.9. In the selection also consider the transport of finished concrete. Such as: direct pumping or vehicle delivery. The volume of the delivery vehicle is also an important basis for determining the type of mixing station.
Construction environment and construction object
In the choice of the purchase of concrete mixing plant, should be fully taken into account the construction and construction of the environment, so as to ensure the smooth construction and construction quality. In the following circumstances we suggest that you are well prepared.
When the site to be a one-time pouring a larger amount of high quality requirements, and there is no reinforcements near the mixing station, the best choice of two smaller mixing station, or choose a master of a pair of dual-machine preparation. When the site traffic inconvenience, maintenance personnel access to the site need to spend a lot of time, the best choice with the same smaller specifications of the double station, or prepare enough spare parts, so as to ensure the smooth progress of construction.

Detailed classification of concrete mixing plant
I believe that a lot of friends just contact the concrete mixing plant on the type of mixing station is not very understanding, and now I am here to give you a brief introduction to the detailed description of the concrete mixing station.
1. According to the purpose of the production of concrete products can be divided into engineering concrete mixing plant and commercial concrete mixing plant, the two categories are more common name. Engineering concrete mixing plant produced by the product is generally more single, for a project, the general productivity is limited; and commercial concrete mixing plant products are widely used in different sites of the site demand, like the same commodity circulation.
2. According to the concrete mixing plant structure, can be divided into mobile concrete mixing plant and fixed concrete mixing plant. Like the construction site to produce multi-purpose mobile concrete mixing plant; and in the fixed area production is fixed.
3. According to the concrete mixing plant layout, it can be divided into single-stage and two-stage concrete mixing plant. In general, the double-stage production efficiency is relatively low compared to the single-stage type, and the production rate is slow.
4. According to the concrete mixing station work, it can be divided into semi-automatic concrete mixing station and automatic concrete mixing plant. The main difference between these two types of control system is the way, generally semi-automatic for the production capacity of small, less production tasks of the mixing station used; fully automatic production capacity requirements for the use of high mixing stations.
5. According to the concrete mixing station operation form, can be divided into two types of periodic and continuous. The difference between the two is that the periodic feed system and the discharge system are circulated in accordance with a certain cycle, while the continuous feed and discharge are carried out continuously
6. According to the scale of concrete mixing station, generally divided into small concrete mixing plant large and medium-sized concrete mixing station two categories. The difference between these mixing stations is mainly for the production efficiency, production capacity and production of concrete types.
