Сложно себе представить выполнение больших volumes of construction work without mixers, especially if there is no possibility of preparing a solution in large volumes directly on the object. For correct calculations, a number of points should be considered. One of them is knowing how many cubes of concrete are in the mixer, which makes it possible to determine the total volume of the working mixture and the possibility of a single transportation of the required amount of mortar.
The considered device is installed on the car chassis. The work item in which mixing and transportation of concrete takes place consists of the following structural details:
Before finding out how many cubes are in the mixerconcrete, consider the principle of operation of this technique. An important factor in the quality of the preparation of the solution is the uniform mixing of the loaded components. A rotating drum with a screw mixing device is responsible for this moment.
The mixer is a fixed screw,mixing operation is performed by rotating the drum. When filling the raw material, the mixture over the surface of the screw goes deep into the tank, where it is mixed to a uniform consistency. To unload the finished concrete drum rotates in the opposite direction. In this case, the screw nozzle will facilitate the exit of the contents of the mixer outside, pushing it forcibly.
How many cubes of concrete in a mixer, depends largely on the modification of the automobile chassis and drum. Among the many types of concrete trucks mention the main distinctive parameters:
Concrete mixers are available on various truck chassis. Domestic units are most often mounted on KamAZ, as well as MAZ, ZIL and the Urals. The capacity of the concrete depends on the volume of the drum.
Foreign analogues are most often used.modifications of trucks "Scania", MAN, "Mercedes", "Nissan", "Mitsubishi", "Volvo". The main factor determining the one-time capacity of the working mixture is the volume of the working drum. In world practice, several standard values have been adopted, making it possible to optimize production needs, depending on the scope of work.
How many cubes of concrete in a KamAZ mixer?In domestic production, the following parameters are provided for the volumes of the working drum: from 2 to 12 cubic meters. Most often ordered mixers with a capacity of five, seven, or nine cubic meters. Foreign modifications mainly use a volume of 6 cubic meters. m
Discharge of the finished solution, regardless ofhow many cubes of concrete in a MAN mixer or another car are made in two ways: forward or backward. Front unloading is performed under the direct control of the driver. This method is common with foreign manufacturers.
In the second case, the unloading of concrete occurs through a special neck in the back of the equipment. This method is practiced in domestic production, it is considered more reliable.
Mixing drum rotates by motor withhydraulic and mechanical drives. The power plant is sometimes presented in a combined version. The engine distributes the power that is spent on the movement of the machine and the rotation of the drum. The best option is an autonomous power unit, the power of which is directed only to the rotation of the tank and the unloading of the concrete solution.
How many cubes of concrete in the mixer MAZa, discussed above. But, besides the main drum unit, a number of extras are included in the package of most mixers. Among them:
An important point is the question by definitionreal volume of concrete solution delivered. This is especially true of bringing the solution in mixers, the capacity of which exceeds the volume declared by the customer. There are several ways to determine how many concrete cubes are in a mixer.
At the enterprise, as a rule, is heldweighing shipped mortar. In this case, it is not so difficult to calculate the volume of concrete. It is necessary to divide the mass of the mixture into its density, the values of which are given below:
Also find out how many cubes of concrete are inMixer (standard) can be at the time of emptying the drum. On average, unloading one cubic meter of the mixture takes about 5 minutes. Consequently, emptying the machine with a volume of 6 cubes will take about half an hour.
It should be noted that during long shipments with loaded mixers, the concrete mix is prepared directly in the drum.
In the cold season, in addition to standard components, additives and chemical reagents are added to the solution, which do not allow concrete to freeze quickly.
Выбирая автомобильный миксер для транспортировки concrete, pay attention to the cleanliness of the inner surface of the drum. Poor washing or lack of it causes the obligatory layering of cured concrete residues on the walls. Over time, this mass will only increase, and it will be almost impossible to determine the actual amount of the solution. In addition, the frozen mixture prevents the normal rotation of the drum, worsening the uniform mixing of the components and the quality of the final product.
The car mixer is an indispensable tool.on modern construction sites. It is used on large-scale complexes, as well as in the construction of country houses or cottages. In addition, the machine is used to fill pools, various platforms, terraces, columns and other concrete structures. Technique significantly speeds up and facilitates the workflow. Depending on how many cubes of concrete are in a Scania mixer or another vehicle, the total fill volume at the construction site depends. Therefore, before ordering a solution, it is necessary to carry out accurate calculations in order not to overpay for the surplus, or not to re-finish a small area for which there was not enough concrete.
