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 .

portable concrete batch plant management approach

People of this philosophy fully integrated into the standardized construction, the image of the industry has improved significantly . Guizhou adhere to standardize the construction site and combine to create a civilization of peace . For migrant workers jianxin portable concrete batch plant , the units from the project approach began to develop a detailed management approach viable service workers , establishment of labor management office and service workers training school , set up standardized dormitories, canteens , jianxin batch plants for sale  toilets , visit room . Unified approach to buy insurance for workers , free medical , unified pre-job training, uniform with metal frame bed , cupboard , quilts , issuing uniforms, uniform in the big canteen , uniform IC card Canteen , labor wages paid on time every month . Construction workers for the rich leisure life , the station building Library project site , installation of fitness equipment such as culture, sports facilities , and established the site supermarket. Ningsia E. hillside to Maojiagou highway construction of the " activity room migrant workers " and other cultural activities , uniform regulations of migrant workers accommodation. Comfortable, clean environment of the site , warm, harmonious living environment , completely changed in the past road construction dirty, chaotic, and poor management of the extensive phenomenon .

concrete batch plants works

JIANXIN concrete batch plants is divided into four parts: sand feed, powder to feed, water and feed additives, transmission and storage of its workflow stir shown in Figure 1. , the mixer control system power, into the human - machine dialogue interface, system initialization process, including the recipe number, grade of concrete, slump, producers, etc. according to the amount carried on each silo weighing, measuring bucket. detected, the output signal feed empty or full material, prompting the operator to determine whether to activate the control program starts stirring the sand, stone belt motor fed metering hopper; open fly ash, cement tank valve, start the screw conveyor ash electromechanical cement into the metering hopper; open water storage tank and additives and admixtures control valve so that water flows into the metering hopper metering meet the set requirements after Doudou door open metering, mixing the ingredients into the blender has started to set. time to open the door mixers, concrete has received material into the mixer.

portable concrete plant assessment system

Comprehensive comparison of Guangdong Province shows that demonstration projects roadbed , bridge , tunnel project qualified rate , respectively, compared with 10.6% before the event to improve ,JIANXIN concrete mixer plant and 1.9%. Sichuan, Yunnan real-name registration system to implement key projects , Jiujiang Yangtze River Bridge implement concrete appearance quality grading assessment system , broken down by management and systems complete, we achieved a fine requirements, but also to ensure the quality of the project . Liaoning Provincial Department of Transportation deputy director Liu chu said JIANXIN self loading concrete mixer : "' Five of ' activity concept has gained , has been transformed into real productivity ." Promotes the standardization process management efficiency, effectively alleviate the arduous task of building relatively scarce and management conflicts .

portable concrete batch plant prevention of pollution occurring

Prevention of ready-mixed concrete mixing useful standing pollution occurs in the process of production and transportation , to further improve urban air quality situation , ready-mixed concrete companies JIANXIN ready mix concrete plants city united rectification searched serene environment quality , choice of 40 pre environmental standards mix concrete companies organized to stop aging charm rectification.
Ready-mixed concrete companies in Taiyuan required after completion of the regulation Incident, by Taiyuan Municipal JIANXIN batching plant manufacturers , Municipal Environmental Protection Bureau after passing inspection links before regulation comeback production ; Where acceptance of non-compliance of corporate succession stop aging charm rectify ; short deceitful or not corrective No unauthorized re-production of biographical income recorded in corporate bad behavior record , and adopted another way to force bankruptcy .

portable concrete batch plant raw material mixing

"From our grasp of the environment, because of the lack of origin , 40 % to 50% are exercisable dilute sand, prime gathered in Panyu , Haizhu or Zengcheng near the riverside area, namely water transport relative to contest a little more convenient premises . But north of Baiyun District , northern Huadu District , Conghua will be relatively less . " JIANXIN concrete ready mix plants first volume of the persons concerned Municipal Construction Committee , Guangzhou City on the subway , affordable housing and the same East Tower , West Tower and other key engineering experiments focus on abstinence , in recent years the focus did not invent the original signs of substandard materials engineering foundation.
Guangzhou passing on sand has been detected more severe "internal scale ." Guangzhou a few years ago on a rainy day , has been aware of this problem, achievements imprison section also works in JIANXIN self loading concrete mixer to enhance the quality of the raw material mixing station for monitoring checks, forcing sampling at least once each quarter , in addition there are a number of frequently searched .
