Aggregate batching system

Because the bin loading is affected by auxiliary equipment and site, the volume of the bin should be selected to be larger。

For the mixing station, the volume of a single bin is generally greater than 20m3, and if the belt conveyor material or concrete bin is used, it can be larger to reduce the area of the storage yard。For the mixing building, the volume of a single bin is generally greater than 50m3。Concrete mixing plantGenerally by the batching station，There are two forms of its structure，All steel structure batching station adopts ground batching，Easy maintenance，Easy drainage，But feeding is difficult，Loader or belt conveyor materials are mostly used;The bin of the steel-mixed structure batching station is a concrete structure，Bin batching，Easy loading，Easy to keep warm，But maintenance is difficult.，Loaders, bulldozers or dump trucks can be used for direct loading。

Aggregate lifting system

Generally using belt machine and hopper to lift, belt conveyor production efficiency is high, reliable performance, easy to close, not easily affected by climate, low maintenance costs, but covers a large area。Lifting hopper is generally only used in mixing station, compact structure, small footprint, but high maintenance costs, poor reliability, in large mixingConcrete mixing plantHave fallen out of use。There are also patterned belt and trough belt conveyor, lifting Angle can be greatly improved, trough belt can be vertically lifted, but because of its reliability and the problem of back belt material is not good to solve, generally used is not much。

Mixing main building

Generally, it is fully enclosed, with a centralized dust removal device, and cold areas should also consider the requirements of winter construction and insulation。Open mixing plant and simple mixing plant, due to poor environmental performance, new productsConcrete mixing equipmentIt is rarely seen and has been banned in some areas。

Measurement system

The weight measurement method is divided into two forms: cumulative measurement and independent measurement。The cumulative measurement structure is simple, easy to maintain, and the loading height is low, but the measurement accuracy cannot be controlled separately。The measurement accuracy is controlled by independent measurement, the structure is more complex, the loading height is increased, and the cost is increased。

Powder storage and conveying device

The quantity and size of the powder storage tank should be configured according to the needs, generally determined by the type and availability of materials, and the powder tank should be equipped with a level controller。The powder conveying device generally has the following two kinds: the pneumatic conveying structure is simple, the feeding is uniform, but the long-distance conveying, the air pressure is not easy to control;Screw conveying distance is long, easy to arrange the overall structure, reliable work, the vast majority of mixing stations or mixing buildings are using screw conveying。

Parts and components

Kit selection is often determinedConcrete mixingReliability of equipment。General accessories should choose well-known brands with high reliability, especially the main accessories。For domestic equipment, electronic components, sensors, cement disc valves, and evenagitatorThe reducer, lubrication components and other imported components are more reliable。

In short, to buy a good set of commercial concrete mixing equipment needs to consider various factors。
