Ready-mixed concrete mixing plant classification

Ready-mixed concrete is defined by the cement, aggregates, water and admixtures as required incorporation, mineral admixtures and other components by a certain percentage, the mixing station was measured after mixing and the use of vehicles sold in the regulations transported to the point of use within the concrete mix. Concrete centralized agitation in favor of the use of advanced technology, the implementation of specialized production management. Equipment utilization, accurate measurement, the dry material with good investment after sufficient mixing concrete mixers, concrete mixing truck is loaded, so good product quality, less material consumption, high efficiency, low cost, but also improve working conditions and reduce environmental pollution.cement-stabilized soil
Ready-mixed concrete plants of fixed, mobile and semi-mobile three.
Large scale fixed ready-mix concrete plants, output per hour is generally 100 to 120 m 3. Fixed ready-mix concrete plants by the process can be divided into single-stage and double-stage type categories. ① typical single-stepped a concrete mixing plant is usually divided into five, six, top-down process. The top layer of the material is stored, transported into and there is a variety of aggregate and cement were the hopper. Water from the pipe into the tank. Its lower layers of ingredients, there is a control room and automatic batching scales, cement, aggregate and water proportionally various weighing. Then the next layer is stirring, equipped with a stirrer, with a good raw materials are unloaded into the hopper mixer mixing evenly discharged into the hopper, leading to all kinds of transport vehicles into the bottom; shipped pouring locations. Features ② two stage plant hopper is low, raw materials twice improved. Plant height reduction, flexible layout can save investment. Semi-mobile ready-mix concrete plants generally use simple plant, production equipment can be removed, and then transfer the assembly. Output per hour is generally 60 to 80 m 3. Mobile ready-mix concrete plant factory with no mixing system, the bunker sand, stone and cement, weighing and transport systems are assembled in a steel device. The dry material is loaded with good concrete mixing truck, into the mixing water, walking mixed, transported to the construction siteconcrete mixer machine
Technology advanced factory automation applications weighing electronics materials and feed, choose the right mix, test the moisture content of the sand and adjust the amount of material, showing silo material level, the production system linkage interlock and fault alarm.

precast concrete plant rescue missions

It is understood that the high conservation center being responsible for 320 National Road, outside the routine maintenance tasks 35.5 km highway and minor repairs and medium-sized repair tasks 171.8 km on the jianxin precast concrete plant branch custody of the road , but also bear 320 State Road , Yichun City, the main economic trunk emergency rescue missions. " This is both a conservation -weather base , but also a weather emergency support center, or service inn on ordinary roads ." Yichun City Roads Authority responsible person, the high conservation center reached a preliminary set of maintenance, emergency rescue , service , etc. functions in one, integrated conservation center for the construction of the province to provide a reference .
"Twelve Five" period, Jiangxi Province will build conservation , emergency services "trinity" of 50 common trunk portable batching plant conservation center. 20 municipal comprehensive conservation center the first building , located in the province's 11 districts and set up near the trunk or important regional general , all projects will be completed before the end of 2012 .

Steady growth in major portable batching plant

"Steady growth " Let sluggish construction machinery industry ushered in the dawn. Just a few days , the construction machinery sector to become the brightest star in the A-share market . jianxin concrete batching plant manufacturer first quarter of excavators, bulldozers , rollers and other products were down 40% year on year . But a package of policy measures to stabilize the growth of the State Council recently launched , is changing the expectations of the market. April , the NDRC approval of the project 328 , the state budget funds growth has reached 28%. CITIC Securities believes that this means that from the beginning of May and June , railway , highway , water conservancy infrastructure investment represented rapid growth is expected to rebound . February 25, 2013 , cement and Shanxi signed a strategic cooperation framework agreement in Zhuhai City, Guangdong Province , the two sides agreed to carry out jianxin ready mixed concrete plant in the cement and concrete products business areas of strategic cooperation , through the powerful combination of complementary advantages and common development , and cement and concrete commodity markets. A dark horse in the cement industry to layout Ling Li , rapid development , good benefits , and cement, concrete integration business model known Chinese cement and concrete products industry .

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.

The hopper is a portable concrete batch plant and pumping systems

The hopper is a concrete mixer and pumping systems, distribution systems tied concrete mixer three major components , each system structures are undertaking different tasks , in which the pumping system is the most important part of the mixer , but the professional operation and managers , to understand the structure and principle of jianxin portable concrete batch plant to reasonable maintenance and repair .
1 Hopper
Hopper is the order of the concrete pump feeder . Hopper and agitator function:
1 ) When the concrete transport equipment to pump feed rate is inconsistent with the pumping speed , the hopper can play a regulatory role in the middle .
2 ) a second stirring means for stirring the concrete can be improved pumpability of concrete .
3 ) the mixing device has a dispensing valve for concrete , concrete cylinder feeding effect, can improve concrete pump suction efficiency.
2 hopper sieve
Hopper sieve effect : Set hopper sieve to prevent oversized concrete aggregates or other debris into the hopper , to stationary concrete batching plants failures, mechanical protection , but also to protect the personal safety. When pumping , and definitely not removed hopper sieve.
3 . Mixing blades
When the stirring blade unit , it should be noted direction . When stirring shaft forward , watching from the side of the hydraulic motor is clockwise , while the role of the blades is to be put forward at the time of the shaft concrete hopper agitation from both sides toward the middle .
