Conveying system

Material handling consists of three parts:

1.Aggregate transport:Mixing plant transportationThere are two ways of hopper conveyor and belt conveyor。The advantage of hopper lifting is that it occupies a small area and has a simple structure。The advantages of belt conveying are large conveying distance, high efficiency and low failure rate。Belt conveying is mainly suitable for mixing stations with temporary storage of aggregates, thereby improving the productivity of mixing stations。

2.Powder transport: The powder available for concrete is mainly cement, fly ash and mineral powder。The commonly used powder conveying method is screw conveyor conveying, and large mixing buildings use pneumatic conveying and scraper conveying。The advantages of screw conveying are simple structure, low cost and reliable use。

3.Liquid transport: mainly refers to water and liquidadmixtureThey are transported separately by pumps。

Storage system

The material storage methods available for concrete are basically the same。Aggregate stacked in the open (there are also large urban commoditiesConcrete mixing plantWith closed silo);Powder is stored in completely closed steel structure silos;The admixtures are stored in steel structure containers。

Control system

The control system of the mixing plant is the central nerve of the whole equipment。The control system has different functions and configurations according to different requirements of users and the size of the mixing station. Generally, the small mixing station control system available on the construction site is simple, while the system of the large mixing station is relatively complex。
