A concrete batching plant is a combined device for centrally mixing concrete, also known as concrete precast field. Due to its high degree of mechanization and automation, its productivity is also very high, and it can ensure the quality of concrete and save cement. With the development of municipal construction, the use of centralized mixing to provide commercial concrete mixing plants has great advantages, so it has developed rapidly, and created conditions for the promotion of concrete pumping construction and the realization of the combined operation of mixing, conveying and pouring machinery
The concrete batching plant is mainly composed of five major systems including mixing host, material weighing system, material conveying system, material storage system and control system and other auxiliary facilities. Compared with the station aggregate measurement, the building aggregate measurement reduces four intermediate links, and the vertical blanking measurement saves the measurement time, thus greatly improving the production efficiency. In the case of the same model, the production efficiency of the mixing plant is one-third higher than that of the mixing station.
Generally speaking, concrete batching plants are divided into two categories: fixed batching plants and mobile batching plants, which are the first classifications that many manufacturers distinguish during production. Most of the fixed batching plants also adopt a modular and easy-to-splicing design, which is mainly used in large-scale commercial concrete manufacturers or related manufacturers of concrete components, and can be used in large-scale engineering construction. It is characterized by strong production capacity, stable work and anti-interference. Good sex. The mobile mixing plant is pulled by a trailer unit, which has good mobility and makes production more flexible. It is mostly used in various small and medium-sized temporary construction projects, and can be rented for personal use.
According to the purpose, it can be divided into commercial concrete batching plant and engineering concrete batching plant. Commercial concrete batching plant is a concrete batching plant mainly for commercial purposes. It should be efficient, economical, and meet the requirements of environmental protection. For self-use purposes, consider whether it is compatible with your own project.
According to the layout process, it is generally divided into first-order type and second-order type. The first-order type refers to the one-time lifting of sand and gravel aggregates, cement, etc. to the silo on the roof of the mixing station. Various materials follow the production process from top to bottom. It is carried out, and finally the material is discharged from the bottom layer, which is more common in mixing buildings. Such a mixing station is divided into silo layer, weighing layer, mixing layer, and discharge layer from top to bottom. The mixing efficiency is very high, but the construction is difficult, the demolition is inconvenient, and the investment cost is high. In terms of stage, after weighing the aggregates and then lifting the mixer again, although it occupies a large area and the mixing efficiency is slightly lower than that of the first-stage type, it is easy to disassemble and assemble, the manufacturing cost is low, the installation is easy, and it is widely used. The production capacity of the batch mixing plant is comparable to that of the first-order type.
According to the number of mixers, the mixing plant can be divided into single-host and double-host. The model name of the double-host batching plant is 2HZS series concrete batching plant. The theoretical productivity of the double-host batching plant is 2*25 m³/h. The double-host batching plant is a good supplement to the same type of batching plant.
According to the weighing method, it can be divided into independent weighing and cumulative weighing. Individual weighing will be equipped with a separate weighing unit for each material. After each material is weighed, it will be added to the mixer to stir. This weighing method High precision, but complex design and high cost; cumulative weighing is to add all aggregates into a unified hopper, which is easy to accumulate errors, which is unfavorable for final production, and the more batching bins, the more prone to deviations, not suitable for used in large projects. However, the structure design is simple, and the cost is cheap.
