Concrete batch plants, and introduce the main site

Concrete batch plants mainly by: Aggregate supply metering systems, cement and fly ash supply and metering systems, water supply and metering systems, metering additive supply system, electric control system, pneumatic system components.concrete batch plants to the cement, sand and gravel aggregates, water and admixtures, additives, etc. by mixing After stirring into concrete steps.

Concrete batch plants main parts are: RCC gravity, basic defect treatment and diversion tunnel closure, etc,Concrete batch plants major security projects. Concrete batch plants based on topographical features, in a reasonable and economic principles for system layout. Arrangement of main facilities and equipment: mixing between buildings, cement tank, fly ash cans, admixture storage configuration, between repairs, power distribution room, laboratory etc, systems and batching system mixing floor layout includes: HZS180 type concrete mixing plant,concrete batching plant feeding belt conveyor, cement fly ash cans and cans. Mixing plant and ancillary equipment are installed ground elevation 248m, of which a powder cans, 2 and 3 of fly ash cement tank beside the mixing tank floor layout.

For the portable concrete plant of concrete

Workers Sunaba to reporters , a few years ago , in which several large Sunaba in Shenzhen , as well as river sand shipped from all over the sales, but a cubic river sand lowest price but also 165 yuan , many builders are river sand prices too high, and the price of sand as long as jianxin portable concrete plant to buy a cube of sea sand , river sand cheaper than the nearly 120 yuan , so now the Shenzhen market sales of building materials used in construction sand, and sand are used seawater washed " washed sand ." Construction of reinforced sand erosion damage after short life reporter learned that , according to the People's Republic of China Ministry of Construction in September 2004 released the " strict construction sand management advice " in the provisions , sand must undergo purification treatment , only to meet the requirements for the preparation of concrete. If you must use sand , fresh water should be flushed through its chloride ion content of not more than 0.02 %. But reporters at the scene saw the sand wash water , still water, do not use fresh water. After the experts say , does not meet the sand containing chloride concrete batching plant state regulations , if a large presence in the building, the fission process of erosion of steel , is specifically classified as the incubation period and period of development, through these two stages , the use of sea sand the basic architecture can be called dangerous . Compared to the state 's 50-year civil life, building sand short life a lot.
