Dry Mix Concrete Plant Suppliers
Haomei Machinery is one of the listed dry mix concrete plant suppliers in China with years of experience in construction equipment manufacturing. The dry mix concrete plant is a special model of concrete batching plant types, it do not need a concrete mixer, no water tank is need, as the name suggest, in the dry mix concrete batching plant, the batching and mixing process are in dry circumstances, the mixing process in simple and fast. The water is added in the concrete mixer truck, and then mixed into the real concrete. The cost of build a dry mix concrete plant is lower than that of a wet mix concrete plant.
Construction process of dry mix concrete plant suppliers are:
Material selection→determination of mixing ratio→ingredients (sand, gravel, cement, admixture) into the mixer truck→water injection into the water tank of the mixer truck→mixing concrete at the construction site of the mixer truck→pouring and coagulation→curing.
On-site concrete mixing process by concrete mixer truck are:
1, The mixer truck transports the mixture to the site and mixes it dry for 5 minutes
2, Add 60% of the total water requirement (stir while adding water until the end of adding water)
3, Add half of the total amount of admixture (stir for 5 minutes)
4, Add 20% of the total water requirement (stir for 5 minutes)
5, Add the other half of the total amount of admixture (stir for 5 minutes)
6, Adjust the slump (add 50 kg of water each time, stir for 5 minutes, and then measure the slump. If the slump is smaller than the design value, add 50 kg of water again, stir for five minutes, and measure the slump again until the slump is satisfied. Design requirements).
Precautions for dry mix concrete batching plant and key points for on-site mixing operation of mixer truck
1, Verify the mix ratio several times to ensure the most economical and applicable.
2, The dry mix concrete plant must measure the moisture content of the sand and gravel aggregate every morning, noon and night, and at the same time control the amount of each cubic meter of sand and gravel through the operating platform, and mix the ingredients strictly according to the mix ratio.
3, Each aggregate bin is equipped with a vibration device to ensure smooth feeding. At the same time, ensure that all the aggregate on the belt is loaded into the concrete mixer truck.
4, The cement silo is equipped with a vibrating device to ensure that all the cement enters the concrete mixer truck.
5, According to the requirements of national standards, the on-board water meter and the scale of the mixing station shall be calibrated regularly.
6, On-site mixing of concrete by concrete mixer truck shall strictly follow the process of on-site mixing of concrete by concrete mixer truck to ensure the mixing time. At the same time, a proper amount of admixture shall be prepared. When the water consumption has reached the design value and the concrete slump does not meet the construction requirements , increase the amount of admixture in an appropriate amount.
7, In high-temperature and high-heat areas, the silo and stockyard of the dry mix concrete plant should be covered with a roof for shading. At the same time, the temperature of the stirring water should be lowered. The surface of the mixer truck should be covered with sacks, and at the same time, cold water should be poured on the sacks to cool down during transportation and mixing to ensure the temperature of the concrete out of the warehouse.
8, On-site mixing of concrete by concrete mixer truck shall strictly follow the construction process. After adding admixture, it must be stirred at high speed for more than 3 minutes (the mixing speed of dry mixer truck is divided into three levels: slow, medium and fast).
9, The on-site concrete quality of the dry mix concrete batching plant is the whole process of the experimenter's responsibility, and he is also responsible for training the driver's skills to ensure that the driver mixes according to the operation process, ensures the mixing time, makes the mixture evenly mixed, and prevents agglomeration. It is strictly forbidden to add water to the mixer truck without permission. If the slump is too small and does not meet the design requirements, you can add an appropriate amount of admixture carried on the truck under the guidance of the tester, and use it after fully stirring.
