The most common concrete batching plant in the market is the wet mix concrete batching plant, where the water usually stirs the cement and aggregate together within the concrete mixer. However, there is another type called the dry mix concrete batching plant. In this article, you’ll learn what a dry mix batching plant is, as well as the importance of its application.
Understanding the Application of Dry Mix Batching Plant
In general, you should first dry mix the artificially mixed concrete such that the sand and the cement are fully and evenly stirred. If you add the water in before the dry mixture becomes evenly mixed, you’ll realize that the stirring becomes difficult, which in turn, affects the overall quality of the concrete.
The powder mortar used in the dry mix concrete batching plant is also known as dry-mixed mortar. It comprises mineral powder and fine aggregate, with the biggest aggregate particle size not exceeding 5mm. When it comes to the additives and cement, they are added in a certain proportion and are usually stirred fully in their dry state.
Due to the difference in their processes, it’s obvious that the dry mix batching plant is completely different compared to the ordinary wet mixers. Once it’s out of the machine, the dry mix will need a floor structure, drying and heating the sand material is also required. Then, you can lift the sieve and meter the ingredients after being buffered. What’s more, the system also requires a few more things like increasing combustion heating, dust removal, vibration screen, and other requirements. Since certain materials need high precision metering, the measurement aspect is also a bit different. In general, the final product passes via the conveying device and kept in a special finished product warehouse.
The Importance of Using a Dry Type Concrete Batching Plant
Because of the limitations of wet mix concrete plant, the dry type has become an alternative option in the concrete mixing industry. It offers unparalleled advantage compared to the wet type. To begin with, the storage time is relatively short when it comes to wet mixed concrete, with the longest time not exceeding 24h. That means that, eventually, it will condense and be too hard to use.
What’s more, the construction process of wet mix concrete and the overall quality of the project is rather difficult to manage compared to using a dry type concrete batching plant. When it comes to wet mixed mortar, the opening time is usually designed to be 24 hrs. Therefore, the wet mixed mortar makes it a necessity to quickly carry out the construction.
As opposed to the former, the product storage time is relatively long with the dry mix concrete, and can even be kept in the storage for six months. The flexible use of mixing with no waste makes it convenient for construction and application in a variety of production environments, hence, avoiding safety accidents during the project.
Screening of the dry sand is crucial due to the dry-mixed concrete raw materials. According to the wide range of mortars needed for construction, you can adjust the gradation and fineness modulus. With all those factors in mind, the construction of a dry mixer is much better compared to the wet type.
