How to Choose The Right Concrete Batching Plant

Concrete batching plant consists of mixing console , material weighing system , material conveying systems, material storage systems and control systems five major system components and other ancillary facilities .

1. Mixing console
Mixing console mixing their way into forced mixing and self- fall mixing . Compulsory concrete mixer mixing station at home and abroad using the mainstream , it can stir liquid , semi- rigid and rigid variety of dry concrete . Since the fall mixing console main mix fluidity concrete , now rarely used in the mixing station .

Compulsory mixer structure is divided into the spindle by planetary concrete mixer , a single horizontal shaft mixer and twin-shaft concrete mixer . And especially the twin-shaft compulsory concrete mixer has best performance of integrated use . Our concrete mixing plants are used in all twin-shaft  concrete mixers.

2. Material weighing system
Material weighing system is a weighing system is key components affecting the quality of concrete and concrete production cost, divided into aggregate weighing , powder weighing and liquid weighing three parts.

Under normal circumstances, less than 20 cubic meters per hour, concrete batching plant using superposition weighing methods, namely, aggregates ( sand, stone ) with a scale, a scale with cement and fly ash , water and liquid admixtures were weighed and then put into the water , said liquid additive pre-mixed bucket .

Capacity more than 50 cubic meters per hour, mixing station , the use of the said materials weighing independent way , all have adopted electronic weighing scales and computer control . Aggregate weighing accuracy ≤ 2%, cement , powder , water and admixtures are up weighing accuracy ≤ 1%.

3. Material Conveying Systems
Material conveying consists of three parts . Aggregate conveying ; currently concrete mixing plant conveying and transporting belt conveyor with hopper two ways . Advantages of the hoppers is small footprint , simple structure. Belt conveyor has the advantage of conveying distance , high efficiency , low failure rate .

Belt conveyor is mainly used to aggregate temporary storage of mixing station, mixing station to improve productivity. Powder delivery ; concrete powder available mainly cement, fly ash and slag .

Now widely used method of transport is a screw conveyor conveying powder , mixing with large pneumatic conveying and transporting scraper . The screw conveyor has the advantage of simple structure, low cost and reliable. Liquid transport mainly refers to water and liquid admixtures, they were transported by the pump .

 4. Materials Storage Systems
Method of storage of materials is basically the same . Aggregate open dumps ( there are city large commercial concrete mixing station closed silo ) ; powder with a fully enclosed steel silo storage ; admixture use steel container.

5. Control system
The beginning of choosing concrete mixing plant is from a selection of control system, the control system is the central nervous system of the concrete batching plant . Control system based on user requirements and mixing of different size, and they have different functions and configuration, generally construction site available small mixing plant control system is simple, but the system of large mixing station is relativelycomplex .
