The concrete mixing station is mainly composed of 5 major systems, such as the mixing host, the material weighing system, the material conveying system, the material storage system and the control system, and other auxiliary facilities. The following describes the selection principle of the batching machine of the concrete mixing station:
1. Selection of aggregate batching system in concrete mixing station
Because the loading of the silo is affected by the auxiliary equipment and the site, the volume of the silo should be selected to be larger. The volume of a single silo of the mixing station is generally greater than 20m3. If a belt conveyor is used to feed or the concrete ground silo can be larger, it can reduce the area of the stockyard. The volume of a single silo for a mixing building is generally greater than 50m3.
2.Precautions for selection of metering system in concrete mixing station
At present, the weight measurement method is adopted, which is divided into two forms of cumulative measurement and independent measurement. The accumulative metering structure is simple, easy to maintain, and has a low feeding height, but it cannot control the accuracy of the metering alone. Independent measurement controls the measurement accuracy separately, the structure is more complicated, the height of loading is increased, and the cost is increased.
3. The concrete mixing station is generally fully enclosed and equipped with a centralized dust-removal device. In cold areas, the requirements for cold protection in winter construction should also be considered, and the exterior insulation should be done. Open mixing stations and simple mixing stations, due to poor environmental performance, new commercial concrete mixing equipment is rarely seen at present, and has been banned in some areas.
