Raw materials management of YHZS25 mobile concrete mixing plant

The raw materials used for 25m3/h concrete mixing station are mainly cement, sand aggregate, fly ash, water and admixtures. After mixing these materials in a certain proportion, they can be mixed and stirred by a forced concrete mixer to form concrete. In addition to the accuracy and reasonable degree of grading affecting the quality of concrete, the quality of various materials itself has a certain impact on the quality of concrete. Therefore, the raw material management of factory price concrete mixing plant is very important.

For the management of cement, the selection of cement is mainly ordinary Portland cement. The procurement type should choose a brand with good reputation, and each batch of procurement should be quality checked. When the characteristics such as strength, fineness and stability meet the requirements, and then can be purchased and used.

Sand and gravel aggregates also have certain specifications. The mud content of sand and gravel is generally less than 3%, and the stone material should be made of natural graded gravel to make the concrete have better pumpability. The storage of sand and gravel requires the installation of a special gravel yard, which separates different types of aggregates and closes them to avoid dust pollution. In the process of mixing concrete, it is necessary to add an admixture to improve the workability and stability of the concrete, and the proper amount can reduce the amount of cement. The admixture in the hot sale mixing station is stored with a special admixture tank to prevent moisture and deterioration and affect the use effect. Arrange special materials to monitor the remaining amount of materials. When certain standards are met, the materials will be organized in time to ensure supply.

The choice of concrete mixer determines the performance of concrete mixing station

When purchasing some large-scale mechanical equipment, it is often necessary to focus on the core components of the equipment, which is often referred to as the mainframe. For concrete mixing equipment, it mainly focus on the host, control system, weighing system and other aspects. These are the most important factors in evaluating a concrete mixing plant for sale. The main machine is the concrete mixer. Now the domestic mixing station mainframe is mostly JS series forced concrete mixer, which is the key to determine the production efficiency of concrete batching plant.

For JS series forced mixer, for the forced stirring principle, the material is very evenly stirred and the mixing quality is very good. And it has high mixing efficiency, which can adapt to the mixing of various materials, and is suitable for the mixing work of various types of concrete. There is also a large concrete mixer, the vertical axis planetary concrete mixer, which also has excellent performance and has a wider range of uses.

The selection of the forced concrete mixer should also be considered comprehensively according to the concrete engineering object, characteristics, maximum conveying distance and other specific conditions. And the performance of the forced concrete mixer is different from random. When selecting the model, in addition to the above points, the type and structure of the building, construction technical requirements, site conditions and surrounding environment should also be considered.

The main performance parameters of the commonly used forced concrete mixer should be consistent with the construction requirements. If the capacity is too large, the utilization rate is low; if it is too small, it will not only meet the construction requirements, but also accelerate the equipment loss, such as high concrete strength requirements, construction quantity. For large projects, we can choose the JS500 forced concrete mixer mixing system. The conveying capacity is 25~30 squares. The conveying distance is 200 meters horizontally and 70 meters vertically. The concrete mixing is more complete and uniform than the ordinary concrete mixer, which is comparable to commercial concrete.

What is the impact of concrete pump trucks on construction environment?

In different construction environments concrete pump trucks are used to properly select the equipment and arrangement method of concrete pump. Then we need to study how to improve its production efficiency. In the past, large-scale buildings were cast concrete. In traditional engineering construction, auxiliary equipment such as buckets, elevators, cranes, belt conveyors, etc. were often used for construction. However, these methods have some defects, which are time-consuming and labor-intensive. Concrete pump trucks are ideal concrete conveyors. However, what are the advantages of using truck mounted concrete pump?

The advantage of concrete pump truck construction is energy saving. Concrete pump trucks can solve the horizontal and vertical transportation and watering problems of concrete at the same time, saving some unnecessary and unnecessary equipment. In addition, the construction degree of concrete pump truck is quite high, the labor required is very small, and the construction organization is very simple. The second is efficient and practical. Concrete pumping operations usually need to be carried out continuously. The general construction efficiency is very high and the work progress is fast, which greatly improves the progress of the project. Third, the construction quality is excellent. When pumping concrete, because the quality of the equipment is strict, the successful pumping is a test. The pumping construction is carried out continuously. During the pumping process, the concrete is not easy to be separated, the concrete slump is not large, and the quality of the project is also too hard. It should be noted that the concrete is susceptible to the environment. In the hot summer construction, the conveying pipe should be covered with a wet hood cloth, grass bag, etc., so as to avoid the “dehydration” of the concrete in the pipe, which makes pumping difficult. In cold winter construction, it is advisable to wrap the conveying pipe with insulation material to prevent the concrete inside the pipe from being frozen.
